Agric. Regardless of which, the success in soil management to maintain its quality depends on the understanding of how the soil properties respond to its disturbance through tillage practices over time. Volcanic soils which comprise a minor portion worldwide are generally characterized by their high natural fertility yet susceptible to soil erosion due to their fragility. World population is going on increasing, it may be 2.4 billion by 2050, but stabilizing the yield of crop is questionable in Indian agriculture due to improper management of agricultural land. Producers must consider the advantage and disadvantages of a tillage system before changing systems. The conservation-tillage fields averaged 540,000 earthworms per acre, compared to just 285,000 in conventional tillage. Adv. Weed Sci., 42 : 205-209, Burford, J.R., et al. In some cases, impacts on grain yield varied and the factors responsible for it need to be identified. The improved grain output of wheat was primarily due to increased tiller development in CT treatments during both the years. Agric., Ibadan, Nigeria. 65: 725-730. Agron. Average Pb concentration for surface soils worldwide is 32 mg/kg and ranges from 10. Similarly, maximum most of the growth attributes, productivity components and physical quality charcters were recorded in CT tillage practice. Agron. Field research was conducted at Hancock, WI, from 1985 through 1987 to evaluate effects of conventional tillage, chisel plow, ridge tillage, and no-tillage systems on population dynamics and control of annual weed species in corn grown continuously on a loamy sand soil without irrigation. With appropriate adjustments to crop management, conservation tillage offers a low-risk way of substantially reducing sediment and phosphorus losses from cropland to streams, rivers and lakes. Higher water contents of soil of the sowing period in TS4 provided higher stand density. Conservation tillage systems show higher net returns vs. conventional tillage Fields using conservation tillage practices achieved higher net returns per acre than conventionally tilled fields for both corn (Table 1) and soybeans (Table 2). Weed Technol., 14: 726-733. Several management systems can be used to improve the soil physical conditions. Van Nostrand Reinhold. Associated with the larger yield increase from lime in the no-tillage culture were 1) a higher pH in the 0 to 10-cm soil layer (averaging 6.4 in no-tillage compared to 6.0 in conventional tillage) in the eighth year; and 2) larger increase in exchangeable Ca and a reduction in exchangeable AI in the 0 to 10-cm layer.

Bras, 35: 157-170. by GERAUORK ZELEKE A Thesis Submitted to the University of Nairobi for the Partial Fulfilment of the Requirements for the Degree of Master of Science in Agricultural Engineering ^SfT\ (1995). The NT practice manifested the best results with 3.5-fold fuel saving and 2.2-fold human labor saving as well as 7.8 times more operating area per unit time compared with CT. J. Lead content was found higher at surface soil in comparison to 15 cm depth at all the ten sites. The Soil and Health Foundation, Emmaus, Pa. 67-83, Kaminski.J. Some of the reasons for this apparent discrepancy are because of the physical properties of the soils in semi-arid Africa, Conservation tillage with broad-spectrum herbicides may have the potential to control weeds and enhance cotton (Gossypium hirsutum L.) yield. Conservation tillage is a tillage system that creates a suitable soil environment for growing a crop and that conserves soil, water and energy resources mainly through the reduction in the intensity of tillage, and retention of plant residues. No-till SOC reserves ranged from 4.8 to 11.6 Mg ha–1 greater than SOC reserves in the other tillage treatments in the 0- to 30-cm depth. However, RT with broad-spectrum herbicides had the maximum weed reduction and lowest dry weed biomass (DWB). Thus, weed scientists have a greater role to play in the development, popularization and adoption of location specific effective, economical and eco-friendly weed management technologies for different ecosystems of India. Tillage is defined as the soil-related actions necessary for crop production (Boone1988). Conservation tillage logarithmically decreased CO2 emissions and the lowest value was determined in NT with 71.4% reduction compared with the CT value (137.4 kg CO2 ha−1). “We can really see an improvement in earthworm populations going from a conventional program to a no-till program,” he says. The highest fuel consumption (47.8 l ha−1) and human labor requirement (8.9 h ha−1) and the lowest equipment working effectiveness (0.17 ha h−1) were determined under CT. C. (2001). Data were collected in 1994 from two experimental sites in Arkansas, USA, one at Marianna and one at Clarkedale. Conservation tillage practices reduce erosion by protecting the soil surface and allowing water to infiltrate instead of running off. 1, 97-98, Lindstrom, M. J., et al. Information on the subject is not presently available but is needed to guide growers in neutralizing soil acidity caused by high rates of nitrogen applied to corn.Because the absence of tillage precludes the mixing of lime with soil when no-tillage corn (Zea mays L.) is grown, an experiment was conducted to determine if surface application would be effective. Ci.Rural 30, 605-609, Kandasamy, O.S. et al eds) Madison, WI. New York. Several studies have examined the effects of tillage practices on soil microbial communities in different cropping systems. Gregory, P.J. Field experiment was conducted in 2010 and 2011 at Agriculture Research Institute, D.I. However, a vast yield gap exists between potential yield and the actual yield obtained due to partial adoption of recommended package of practices by the farmers. Soil Tillage Res., 17: 115-124. and Nelson, W.W. (1973). 94: 153-171. Indian Society of Weed Science and Univ. 93: 836-844, Hill, R.L. Climate change is worsening the situation by imposing water scarcity in India. Gangwar, K.S., et al. Numerous studies conducted in temperate climate zones showed that no-tillage resulted in acidification of surface layer when continued for several years compared to conventional tillage. Consequently, no-till or reduced tillage systems that do not have the soil surface covered by residue in irder to prevent formation of crust as a result of raindrop impact, tend to lose water through runoff in a region where water economy is essential. Crop rotation and also mixed cropping improves soil fertility and also it reduces soil erosion. production has increased in recent years because of several factors including their potential to reduce losses or sequester soil organic C (SOC). Access scientific knowledge from anywhere. Adoption of resource conservation such as conservation tillage practice with residue retention on the soil and diversification of the rice–wheat cropping system with the inclusion of pulses, oilseeds may lead towards achieving overall sustainability of the system. However, increased reliance may be placed on herbicides with some conservation tillage Specific CO2 emissions in NT were lower by 72.1% in vetch and 60.4% in wheat than the CT values. Soil samples were collected at the end of May 2017 from the plots laid out in RCBD replicated four times, then analyzed and data were subjected to ANOVA using GeniStat software. 0000000676 00000 n Thus, it appears probable that the principal mechanism for the yield reduction caused by the lack of lime was reduced growth. The techniques used range from stubble-mulching techniques keeping some residue on the soil surface by doing only some tyne operations. Donovan, J.T. Heavy metals accumulate in top soil [6], and then enters into crop plants and fodder plants and may accumulate in human tissues by the process of biomagnification [7]. Conventional tillage (CT), disking, no tillage with rye removed (RR), no tillage with standing rye (SR), and strip tillage (ST) were evaluated with and without ethalfluralin plus halosulfuron (1.5 plus 0.036 kg ai/ha, respectively) applied preemergence. For this reason, Extension economists at the University of Georgia have completed an investment comparison of conventional- and conservation-tillage equipment using enterprise budgets. Our findings suggest that sustainable cropping systems on hillslopes integrating a blend between organic and conventional doctrines better maintain or improve soil ecosystem functioning. The heavy metal content in arable soils is affected by soil characteristics and cropping practices [9]. Saskatoon, SK. It reduces greenhouse gas emission and also it can improve carbon sequestration. 49, 1270-1273, Hopp, H., and Slater, C.S. Seedling emergence is critical for better establishment of crop. Baeumer, K and Bakermans, W.A.P. xref ... Bornoux et al. The implementation of sustainable soil management strategies is vital for hillslopes and low-fertility soils where plantations cover vast tracts of land. Reduced tillage with broad-spectrum herbicides produced maximum plant height, 100-seed weight, and lint yield. Conservation vs. ; weedy rice; Lantana camara L.; Chromolaena odorata (L.) R.M. Research on Minnesota farms shows that conservation tillage can greatly reduce soil erosion, with minimal effect on crop yields and often at lower production costs than conventional tillage. Tillage helps in controlling weeds by burying weed seeds and emerged seedlings leaving a rough surface to hinder weed seed germination, expose underground parts of perennial weeds leading to their desiccation (Subbulakshmi, 2007). Inst. The effects of two tillage systems and three crop rotations on the aggregation indices were studied. Therefore, the effect of four different tillage practices in a Hungarian vetch–winter wheat crop rotation (CR1) compared to fallow–winter wheat crop rotation (CR2) for water use efficiency was investigated in a semi-arid region with a high altitude (∼1750 m a.s.l.) In 2002, weed populations were significantly greater than those in 2001, and in 2002, regardless of herbicides, yields of mature fruit were greater in tillage treatments with higher rye residues (SR, ST).

Treatments consisted of two planting systems (conventional-tillage (CT) and no-tillage (NT)), under three crop rotations (soybean/wheat/soybean (S/W/S), maize/wheat/maize (M/W/M) and soybean/wheat/maize (S/W/M)) and two layer depths, 0–20 and 20–40 cm, arranged in a split plot design with three replications. (2006). The ST significantly (P < 0.01) decreased BD and PR within 30 cm of soil surface. The mean pod yield recorded (3371 kg ha-1) with improved practices was 24.39 percent higher than farmer’s practice (2710 kg ha-1). Conservation tillage offers an alternative approach for managing clayey soils in the midsouthern United States. : 65-93. Main objectives of conservation agriculture is reducing tillage, year round cropping, crop rotation, mulching may be live or residue. ; Mikania micrantha Kunth., are a few of many major weeds of concern currently in India. 1961. Conservation tillage decreases soil erosion, leaching of fertilizer, pesticides and herbicides into the ground water. Breakeven yields and prices needed to realize a return on investment were also … 33, 445-448, Congresso Latino Americano de Ciencia do solo 10, Borges, D.F. The maximum microbial population was found in ZT. This study evaluated the effects on SOC of three cropping systems (continuous corn [CC], continuous soybean [CSB], and soybean–corn [SB-C]) in six, Long-term no-till or reduced tillage may decline functioning ability of soils due to surface/subsurface com-paction and/or stratification of plant nutrients. King & H. Comparisons of the two tillage methods were also made without lime to determine the degree of response to lime. Therefore, NT practice could be recommended as the best practice for rainfed crop rotation in semi-arid regions. Book A Systems Approach to Conservation Tillage. We suggest that at this stage soil tillage research in the semi-arid regions of Africa and Asia should re-examine some of the concepts of conservation tillage in relation to soil physical properties and processes in order to obtain a tillage system that ensures high crop yields without destruction of the soil resource. Green foxtail and redroot pigweed were more difficult to control in chisel plow and no-tillage than in the conventional and ridge tillage systems with several herbicide treatments. Tillage includes all operations of seedbed preparation that optimize soil andenvironmental conditions for seed germination, seedling establishment and crop growth (Lal1983). Soc.Am.Proc. %PDF-1.4 %���� Rec. (2001). (2006) In: 18 th World Congress of Soil Sci., July 9-15, 152-159. Conventional tillage is a tillage system using cultivation as the major means of seedbed preparation and weed control. The definition by Ahn andHintze (1990) states that tillage is any physical loosening of the soil as carried out ina range … The no-tillage system had the best aggregation indices for the 0–20 cm layer due to the increase in the organic carbon content. ; Echinochloa spp. The objective of seed bed preparation is to create stress free soil environment (water, mechanical impedance, aeration, nutrition etc.) The most important advantage of conservation tillage systems is significantly less soil erosion due to wind and water. in the New Millennium on Eco-Friendly Weed Management ... Bornoux et al. This person is not on ResearchGate, or hasn't claimed this research yet. Imprint CRC Press. Solublity of metals is influenced by pH of soil, redox potential, complexing agents such as carbonates, sulphates, chlorides and organic acids [10, 11] Lead (Pb) is a major heavy metal pollutant in water and soil. replications. Conservation tillage systems showed higher net returns versus conventional tillage and reduced farmer operating costs. Soil and Water Cons., 39(1): 64-68, Machado, P.L.o.A. By Maureen Kuwano Hinkle. J. Considerably it can save 20-30% of water. 33-45. Information on the subject is not presently available but is needed to guide growers in neutralizing soil acidity caused by high rates of nitrogen applied to corn. Copyright © . Experiment was conducted applying randomized complete block design based on split-plot trial plan. Water contents in 30–60 and 60–90 cm soil layers in the TS4 practice also were higher than the TS1 practice values. (1993). Intensive cultivation and excess chemical fertilizer continuous tillage activity have shown that environmental, soil & water degradation in South Asia has produced serious problems in soil health or agricultural development with a rise in population. ; Leptochloa chinensis (L.) Nees. To read the full-text of this research, you can request a copy directly from the authors. Water contents of soil were the lowest in the TS1. South African J.Plant and Soil. Khan, Pakistan to examine tillage and herbicide effects on weed control and cotton yield in wheat-cotton system. Tillage is needed to make proper seed-bed, which varies with the crop to follow and largely depends upon soil types, nature of preceding crop and residue management systems. 0000001220 00000 n Weed Sci., 44: 314-322, Dheer Singh and Tripathi, R.P. It was more noticeable in no-tillage corn than in conventionally tilled corn. The experiment was arranged in split plot in RCBD with 4, The use of conservation tillage systems for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] 0000002271 00000 n (2001). Ohil Agric. Soil Sci. This makes the field unsuitable for cultivation of crops in future. 16-17 Feb. 1989, 99. Soil samples were collected in depth increments of 0 to 7.5, 7.5 to 15, and 15 to 30 cm in the fall of 1989 and 2004 after harvest and analyzed for SOC. J. Although the amount of weeds in winter wheat plots was the highest in the TS4 practice (67.4 kg ha−1) when considering three-year average values, grain yield in TS4 was also high (2652 kg ha−1) and statistically similar to TS1 (2762 kg ha−1). The mean WFPS under NT, RT-2 and RT-3 systems in 0-10 cm and with all tillage systems (except ST in 10-20 cm) in subsurface layers were higher than 60%, which is considered a threshold for nitrogen losses as N 2 O fluxes. L.)-grain maize (Zea mays L.)-winter wheat. Similarly, improved practices had higher sustainability yield index (0.63), sustainability value index (0.47), higher water expense efficiency (74.92 kg ha-1 cm-1), gross water productivity (16.58 ₹ m-3), net water productivity (11.89 ₹ m-3) and incremental benefit cost ratio (30.1) over farmers practice. 61: 119-130, Mahli, S.S and Nyborg, M. (1990). Conservation tillage decreases soil erosion, leaching of fertilizer, pesticides and herbicides into the ground water. Hence, it is important to ensure an adequate seed and soil contact to facilitate water movement into seed, which intern depends upon physical characters of seed bed, thus affect germination and plant stand (Bouaziz, 1987). Soil samples were collected from disturbed and undisturbed plots of NT as well as plots under other tillage systems from three soil depths (i.e., 0-10, 10-20 and 20-30 cm) in November 2016. Conventional tillage (1 ploughing by tractor drawn disc plough + 2 harrowing + 1 fb cultivator with planking) increased grain yield (10.85 percent) and (7.21), both during the first and second years of experimental plots, over minimum tillage (1 ploughing by tractor drawn rotavator) (MT). Frye, W.W., et al.(1985). Soil texture was variable at different sites, sand content ranged from 34.0% to 45.6 %, clay 39.0 % to 45.4 % and silt content was low ranged from 14.8% to 20.6%. Broad-spectrum herbicides (haloxyfop + lactofen) reduced weeds by 92 and 94%, and produced highest lint yield (1222 and 1515 kg ha-1) in 2010 and 2011, respectively. et al.(2000). (1997). 0 Thus, benefits of the zero tillage could be realized only after retaining proper mulch loads and with proper control of weeds. 1. Zero tillage gives smothering effect to weeds but some studies shows that, higher density of perennial grass weeds in reduced tillage systems compared to conventional tillage. Conservation tillage improves activity of earth worm and other soil … This study highlights a balanced design for an integrated production system for rainfed olive orchards that can maintain productivity while suitably encouraging environmental quality and ecosystem services. In the present review, attempt was made to come out with an effective integrated approach which could be used for successful adoption of the zero tillage in north Indian region. The double crops are corn following cotton, and soybean following sorghum; and the cover crops are black oats following cotton, and hairy vetch following sorghum. These conservation tillage all involve less tillage system in comparison to the conventional tillage which involve plowing with 2-3 times harrowing and one time furrowing then crop planting. 34 19 Soc. particularly the Sahelian zones where the soils are sandy, have high bulk densities and therefore low total porosities and form crusts upon wetting and drying. So to evade these problems, conservation agriculture is the only way. Improvement of tillage-sowing practices can be a practical way of sustainable and environmentally friendly production by decreasing fuel and CO2 emission and increasing yield in a rainfed crop rotation [Hungarian vetch (Vicia pannonica Crantz)—winter wheat (Triticum aestivum L. cv. 0000003718 00000 n Doran, J.W. 23-24:176, Dick, W.A., et al. The results obtained from various studies showed that the no-till treatment caused lower infiltration rates ( Abu-Hamdeh, 2002;Lipiec et al., 2006;Matula, 2003). The highest weed infestation, seedling density and the shortest emergence time were determined in this practice. The effect on cropping efficiency, machine productivity and development economy of two tillage cum (Vermicompost and FYM manure, Urea, and DAP) or two facts regarding the application of foliar spray and without zinc fertilizers were evaluated. Parthenium hysterophorus L.; Phalaris minor Retz. Do not till wet or saturated soils -- this can create large clods. (1983). However, the productivity of crops is much lower than many countries and needs enhancement to produce ∼400 million tons of food grains for meeting food demands of a population of 1.7 billion by 2050. Field Crops Res., 69: 27-40, Lang, P.M., and Mallett, J.B. (1984). The results of this study evinced that reduced tillage is suitable in this region, since it is promising in the SOM enhancement. Conservation tillage improves activity of earth worm and other soil micro flora. Soil Tillage Res, 6, 149-161, Lampurlanes, J and Cantero-Martinez, C. (2003). The NT and RT resulted higher BD and PR, and lower MaP and TP than CT and ST in all three depths, though the values were generally not limiting for crop growth. 0000004306 00000 n Soil Till. Znut.Cycl. 44:765-771, Duglas, J.T., and Goss, M.J. (1982). Samples were collected at the IAPAR Experimental Station, Londrina, state of Parana, Brazil, from an experiment that has been carried out for 21 years in a dystrophic red latosol (Typic Haplorthox). Lead has been widely used as additive in gasoline in last century and has been phased out all over world now. Contaminated soils have several negative impacts on environment including degradation of water quality, decrease in crop yield and crop quality. The maximum N2O emission was recorded in ZT, which was almost 3–6% higher than that of RT and CT, respec-tively. Conservation tillage decreases soil erosion, leaching of fertilizer, pesticides and herbicides into the ground water. J. The pH and exchangeable Ca and AI in the 10 to 20-cm soil layers from tilled and nontilled soil were almost identical. Soil Tillage Res., 11:159-166. Rio de Janeiro, Anais'. Res. Increase in lead content of agricultural soils has been found near industrial areas and high ways. (1988). Bezostaja)—fallow] in semi-arid conditions. Adv.Agron. In: First Biennial Conf. The water losses with evaporation rise if soil surface is bare. (2006) reported higher carbon accumulation rates (around 0.4-1.7 t C ha -1 year -1 ) under zero tilled conditions compared to tilled condition. Soil Sci. Soil Sci., 70: 203-214, Cavalaris, C.K. Ehlers, W., et al. Notwithstanding, it seems that since most of the SAT soils are structurally unstable, further conventional tillage even though it has ephemeral advantages, may in the long term be exacerbating the problems of structural instability and their deleterious effect on water and soil conservation and therefore on crop production. 40, 762-768, Lal. Rep. 71-72, Calegari. There was no clear effect on water use efficiency of winter wheat of the no-tillage practice compared to conventional tillage practice. Due to higher residue in surface soil in conservation tillage, it will improve soil organic carbon content, while other work reported a decrease in soil organic matter compared to ploughed soil down to a depth of 10 cm after 3 years of study. This combination is an optimum weed management strategy that contributes significantly to cotton production. Numerous studies … Similarly, SOC concentrations and reserves were greatest in CC and least in CSB, with intermediate values for SB-C in all tillage systems. Soil Tillage Res, 14, 34-58, Lal.R. Fields using conservation tillage practices achieved higher net returns per acre than conventionally tilled fields for both corn and soybeans. The olive yield responses to each production system were evaluated, and the selected physico-chemical soil properties (pH, bulk density, soil organic carbon, cation exchange capacity, total N, P, and K), soil enzymes (β-glucosidase, protease, dehydrogenase, and phosphatase activities), and soil-microbial biomass C and N were monitored. Here, we show a substantial improvement in soil health restoration using the organic rather than a conventional system. Factors gorverning heavy metal content in crop plants are soil properties, water quality, climatic parameters, agrochemical application, plant uptake and plant parts [8].
