Tillage Practices

In a brief review, earlier German and English attitudes to tillage research are contrasted, especially on the emphasis on soil structure v emphasis on weed control; the effect of the advent of zero tillage on this difference is discussed. It was concluded that chemical weed control gives greater freedom in tillage practice, and research is revealing risks that may be unacceptable for certain crops when tillage practices are changed.

A field experiment was conducted to evaluate the plant height, yield and yield attributes of wheat under different tillage practices and nitrogen level at Dang, Nepal during winter season 2018-19. The experiment was laid out in split plot design with two tillage practices viz. zero tillage and conventional tillage as main plot factor and four level of N viz. 50 kg ha-1, 75 kg ha-1, 100 kg ha-1and 125 kg ha-1 as sub plot factor and each replicated thrice.  The result revealed that there is no significant relation between tillage practice and plant height of wheat while N level significantly affect the plant height. 125 kg N ha-1 recorded the highest plant height (110.7 cm). Zero tillage recorded the highest effective tiller m-2 (254) and grain yield (3.3 t ha-1) whereas spike length, grain spike-1, biological yield and harvest index were not significant with tillage practices. Regarding the N level, 125 kg N ha-1 recorded the highest effective spike m-2 (279), spike length (10.6 cm), grain spike-1 (48), thousand grain weight (46.3 g), grain yield (3.6 t ha-1) and biological yield (9.4 t ha-1). 50 kg N ha-1 recorded the highest harvest index (42.9%). The interaction between the tillage practice and nitrogen level showed the significant effect on grain yield and harvest index where as other parameters showed non-significant relation. The zero tillage with 125 kg N ha-1 recorded the highest grain yield (3.9 t ha-1).

The present experiment was conducted to evaluate two important conservation tillage practices namely zero tillage in wheat and bed planting for growing vegetables for deciding the economic feasibility of their adoption in Gohana and Kharkhoda block of Sonipat district in Haryana. In first scenario, comparison were made between Puddled transplanted rice followed by conventional tilled wheat (PTR – CTW), and puddled transplanted rice followed by zero till wheat (PTR – ZTW). In second scenario, conventionally tilled Jowar in kharif followed by conventionally tilled wheat system (CTJ – CTW) was compared with vegetables on beds in both seasons (BV-BV). Sowing of wheat by zero till drill in PTR – ZTW system, decreased cost of cultivation by 21% over its value of Rs 20688 in PTR – CTW treatment; increased grain yield by 5% over the grain yield of 5.99 t ha-1 in PTR – CTW treatment. The B: C ratio of PTR – ZTW was 4.65 while that of PTR – CTW treatment was 3.24, which indicated economic viability of zero tillage practice. While in case of cauliflower in BV-BV system, the total cost of cultivation was estimated at Rs 51500/ha and net returns of Rs 38072/ha i.e an increased net return of 5.8 times over the net return of Rs 46223.5 in CTJ – CTW treatment. The B: C ratio of BV-BV was 5.21, while that of CTJ – CTW treatment was 2.35. Thus, it was concluded that in rabi season, cauliflower on beds and zero till wheat are most economically viable options in this temporary waterlogged regions of Yamuna basin.

The influence of zero-tillage practice on soil, weed control during winter fallow and growth behaviour of sorghum and cotton is discussed in relation to conventional practice. In a year of partial drought when all yields were reduced, zero-tillage gave slightly superior results, but when moisture was adequate it depressed yields by up to 40%. The yields of following crops of wheat and vetch after sorghum, were depressed in the zero-tillage plots by 5-30% in 2 field experiments, compared with conventional practice. CCT.

The study was carried out at the field of Regional Pulses Research Station, Madaripur under Bangladesh Agricultural Research Institute (BARI) during Rabi season (winter) to evaluate the effect of different tillage practices on growth, yield attributes, nutrient uptake and yield of chickpea, and to compare between the zero tillage and tillage practice.The experiment was planned with five different tillage practices viz. Zero tillage (T1), Single tillage (T2), Two tillage (T3), Three tillage (T4) and Four tillage (T5), and it was laid out in a randomized complete block design (RCBD) with three replications. Blanket dose of fertilizers of N, P, K, S, Zn and B at 20, 21, 30, 10, 3 and 1.5 kg ha-1, respectively were used in all tillage treatments. The highest mean seed yield achieved (1395 kg ha-1) in zero tillage (T1) followed by four tillage (T5) practice. The maximum number of branches plant-1 and more number of pods plant-1 was recorded in zero tillage treatment. Nutrient content showed non-significant effect across most of the treatment. The highest nodulation and nutrient (N, P, K and S) uptake was also obtained from T1 treatment. Tillage practices exhibited positive effects on soil properties. The highest soil organic carbon, total N, available P, K, S, Ca, Mg, Zn and B were found in zero tillage (T1). Based on profitability, the zero tillage was economically viable with compared to tillage practice. Although this practice (T1) saves the money about 3.8% to 13.7% and time also saves minimum 8 days for succeeding crops. So, the present study suggests that zero tillage practice could be implemented in the high and medium high land for chickpea cultivation. Low income farmers may practice the zero tillage technology. Future research should be carried out to evaluate the suitable rate of nutrient in zero tillage (conservative tillage) practice for yield maximization of chickpea and sustaining soil fertility.

<p>Improved fallows of <em>Sesbania sesban</em> (Sesbania) have been known to improve soil physical and chemical properties and increase crop yield compared to traditional fallows. However, the effects of soil tillage practices after improved fallows on soil properties, weeds, labour and subsequent maize crop have not been assessed in Southern Africa. This study aimed to evaluate how tillage practices affect yield of maize and affect soil properties after two years of fallow and subsequent cropping phase. In this study, done at sites in eastern Zambia, maize yield from a two-year planted Sesbania, natural fallow, continuously fertilized and unfertilized maize were compared under conventional, flat till and zero tillage practices. A split plot experiment, with improved fallow systems in the main plot and the tillage practice in the subplot, was established at the sites. The results showed that the increases in grain yield under conventional tillage over zero tillage practice were 17.8% and 28.2% during 2000/2001 and 2001/2002 seasons, respectively, at Msekera. At Chadiza, the increases in grain yield under conventional tillage over zero tillage were 66.3% and 327.4% during 2000/2001 and 2001/2002 seasons, respectively. Greater maize yields were achieved under Sesbania planted fallows compared to the natural fallow and maize monoculture without fertilizer. Overall, zero tillage practice resulted in lower maize grain yield, higher bulk density, reduced water intake, higher weed infestation and high labour demand during weeding compared to conventional tillage.</p>

In Haryana (India) cotton is generally sown with conventional tillage practices witnesses poor germination and plant establishment. Poor plant stand is attributed by burning of emerging plants due to very high temperature at the time of planting, which is further worsen by crust formation due to pre-monsoon showers. Keeping these points in view, an experiment was conducted with farmers' participatory research mode in village Hajwana of Kaithal district. Cotton sown with zero tillage technique resulted in approximately five percent higher yield i.e. 136.3 kg ha-1 over conventional tillage. Mean returns over variable cost of all the three years were 10.8 percent i.e. Rs. 11794 ha-1 more in zero tillage over conventional tillage. Benefit: cost ratio were 3.86, 3.86 and 4.61 in conventional method of planting, bed planting and zero tillage technique, respectively. Zero tillage planting of cotton reduced fuel consumption by 93.4 % and 91.7 % compared to bed planting and conventional planting respectively.

A field experiment was conducted to evaluate the effect of tillage practices, residue management and cropping system on soil properties at NMRP, Rampur, Chitwan from November 2015 to April 2016. The experiment was laid on Strip split design with combination of 12 different treatments i.e, zero tillage & conventional tillage as main plot in the strip, residue retention & residue removal as sub-plot factor and maize – wheat, maize + soybean – wheat & soybean – wheat cropping system as sub-sub plot factor. Three replications of the treatments were made. Soil sample before experiment and after harvest of wheat was taken (0-15cm). The experiment showed significant effect of zero tillage on organic carbon (2.169%) and on total soil nitrogen (0.112 %). Zero tillage with retention of residues is valuable tool for the conservation agriculture and helps in sustainability of soil however long-term research for the tillage management and residue retention should be conducted to highlight the major effects on change in properties of soil.Int.

The Impact

PRE herbicides are less effective in the zero-tillage system because of increased residual crop stubble and reduced soil incorporation. However, since weeds are not physically controlled in the zero-tillage system, reliance on efficacy of PRE herbicides is increased. This research investigated the impact of carrier volume and droplet size on the performance of PRE herbicides (in wheat crops at four sites in 2010) to improve herbicide efficacy in conditions of high stubble biomass in zero-tillage systems. Increasing carrier volume from 30 to 150 L ha−1increased spray coverage on water-sensitive paper from an average of 5 to 32%. Average control of rigid ryegrass by trifluralin (at Cunderdin and Merredin sites) and trifluralin or pyroxasulfone (at Wickepin and Esperance sites) improved from 53 to 78% with increasing carrier volume. Use of ASABE Medium droplet size improved spray coverage compared with ASABE Extremely Coarse droplet size, but did not affect herbicide performance. It is clear that increased carrier volume improves rigid ryegrass weed control for nonwater-soluble (trifluralin) and water-soluble (pyroxasulfone) PRE herbicides. Western Australian growers often use low carrier volumes to reduce time of spray application or because sufficient high-quality water is not available, but the advantages of improved weed control justifies the use of a high carrier volume in areas of high weed density.

Summary. Continuous cereal cropping in southern Queensland and northern New South Wales has depleted native soil nitrogen fertility to a level where corrective strategies are required to sustain grain yields and high protein content. The objective of this study was to examine the performance of chickpea in chickpea–wheat rotations in terms of yields, water use and N2 fixation. The effects of sowing time and tillage practice have been studied. Chickpea grain yields varied from 356 kg/ha in 1995 to 2361 kg/ha in 1988; these were significantly correlated with the total rainfall received during the preceding fallow period and crop growth. Almost 48% of total plant production and 30% of total plant nitrogen were below-ground as root biomass. Mean values of water-use efficiency for grain, above-ground dry matter, and total dry matter were 5.9, 14.2 and 29.2 kg/ha.mm, respectively. The water-use efficiency for grain was positively correlated with the total rainfall for the preceding fallow and crop growth period although cultural practices modified water-use efficiency. The potential N2 fixation was estimated to be 0.6 kg nitrogen/ha.mm from 1992 total dry matter nitrogen yields assuming all of the nitrogen contained in chickpea was derived from the atmosphere. Sowing time had a much larger effect on grain yield and N2 fixation by chickpea than tillage practice (conventional tillage and zero tillage) although zero tillage generally increased grain yields. The late May–early June sowing time was found to be the best for chickpea grain yield and N2 fixation since it optimised solar energy use and water use, and minimised frost damage. Nitrogen fixation by chickpea was low, less than 40% nitrogen was derived from atmosphere, representing less than 20 kg nitrogen/ha.year. The potential for N2 fixation was not attained during this period due to below-average rainfall and high soil NO3-N accumulation because of poor utilisation by the preceding wheat crop. Increased soil NO3-N due to residual from fertiliser N applied to the preceding wheat crop further reduced N2 fixation. A simple soil nitrogen balance indicated that at least 60% of crop nitrogen must be obtained from N2 fixation to avoid continued soil nitrogen loss. This did not occur in most years. The generally negative soil nitrogen balance needs to be reversed if chickpea is to be useful in sustainable cropping systems although it is an attractive cash crop. Sowing time and zero tillage practice, possibly combined with more appropriate cultivars, to enhance chickpea biomass, along with low initial soil NO3-N levels, would provide maximum N2 fixation.
