Cotton Yield and Lint Response to Tillage System and Irrigation Interval under Wheat Based Cropping System

Background: Horizontal expansion of area under pulses at country level has very little possibilities. This necessitates exploring alternate ways to increase the area and production of pulses. Bt cotton is the major cash crop grown in large area in Southern transition zone of Karnataka on red soils. Bt cotton hybrids are sown at wide row spacing hence provide sufficient space for cultivation of short duration pulses like cowpea and horse gram.Methods: On-farm trials were carried out in medium deep red soils of Basavanagiri village of Mysore district, Karnataka during 2014-15 and 2015-16. There were six treatments consists of Bt cotton with farmers practice (T1), Bt cotton with best management practice (T2), sole cowpea (T3), sole horse gram (T4), Bt cotton intercropped with cowpea (T5) and Bt cotton inter cropped with horse gram (T6). On-farm trials were laid out by using RCBD design in five farmer fields, which served as replications.Result: On-farm investigation indicated that there was no much difference between cotton yield sole crop with BMP and inter cropped cotton yield. However, cotton yield was significantly lower in farmers practice over BMP. Intercropping of cowpea and horse gram with Bt cotton resulted in higher cotton equivalent yield, LER and production efficiency over the sole cotton cropping system. This was due to the wider spacing of the cotton and better resource use efficiency in intercropping system.

SUMMARYReduced tillage is said to be one of the potential ways to reverse land degradation and ultimately increase the productivity of degrading soils of Africa. We hypothesised that crop yield following a modest application of 2 t ha−1 of crop residue in a reduced tillage system is similar to the yield obtained from a conventional tillage system, and that incorporation of legumes in a cropping system leads to greater economic benefits as opposed to a cropping system involving continuous maize. Three cropping systems (continuous maize monocropping, legume/maize intercropping and rotation) under different tillage and residue management systems were tested in sub-humid western Kenya over 10 seasons. While soybean performed equally well in both tillage systems throughout, maize yield was lower in reduced than conventional tillage during the first five seasons but no significant differences were observed after season 6. Likewise, with crop residue application, yields in conventional and reduced tillage systems are comparable after season 6. Nitrogen and phosphorus increased yield by up to 100% compared with control. Gross margins were not significantly different among the cropping systems being only 6 to 39% more in the legume–cereal systems relative to similar treatments in continuous cereal monocropping system. After 10 seasons of reduced tillage production, the economic benefits for our cropping systems are still not attractive for a switch from the conventional to reduced tillage.

Abstract With the advance of the no-tillage system (NT system) in Brazil, the adoption of technologies for nitrogen fertilization in these soils become essential for increasing the efficiency of N use in the system. In this sense, the objective of this study was to quantify ammonia losses, N removal in grains, and with 2nd crop yield in NT system and conventional (T system) planting areas that received application of different N fertilizers and their technologies. Ammonia volatilization, N extraction in grains and corn yield in response to the application of conventional fertilizers were compared to urease inhibitors treated urea in NT and T systems. The treatments were: no-N (Control); Prilled urea (PU); urea + NBPT (UNBPT); urea + Cu + B (UCuB); ammonium nitrate (AN), and ammonium sulfate (AS). In the NT system, the N-NH3 losses were 49% greater than in the T system; without differences for corn yield. The fertilizers as AN, and AS had the lowest N-NH3 losses, regardless of tillage system. UNBPT reduced the mean N-NH3 loss by 33% compared to PU. UNBPT (1,200 mg kg-1) and UNBPT (180 mg kg-1) reduced by 72% and 22% the N-NH3 losses compared to PU in the NT system.

The experiment was conducted at Cotton Research, Training and Seed Multiplication Farm, Jagodishpur, Chowgacha, Jessore initiated June 19, 2015 for the cropping season 2015-16 to observe the performance of cotton based cropping system including total three crops in a year. The other crops were i) relay wheat – mungbean and ii) relay lentil – mungbean. Four cotton varieties CB-12, CB-13, CB-14 and CB Hybrid-1 were sowed in a RCBD design with three replications. Seed cotton yield was significantly different among the varieties. The highest seed cotton yield (2519.3 kg/ha) was obtained from CB Hybrid-1 and the lowest (2112.37 kg/ha) seed cotton was produced by CB-13. The highest BCR (1.31) was observed in cotton (CB Hybrid-1) –relay lentil –mungbean cropping pattern and the lowest BCR (1.10) was observed in Cotton (CB-13) – relay wheat –mungbean cropping pattern. The finding infers that cotton – relay lentil - mungbean cropping pattern might have the potentiality to increase cropping intensity in Bangladesh. J. Environ.

ABSTRACT Determining nitrogen (N) accumulation and export by common bean as a function of straw and of the splitting of this nutrient is very important, aiming at the management and sustainability of agricultural systems. This study aimed to determine the N accumulation and export by common bean as a function of Zea mays and Urochloa ruziziensis grass straw (maize, maize/U. ruziziensis intercropping and U. ruziziensis) and splitting of top-dressing N fertilization. The experiment was conducted in Jaboticabal-SP-Brazil, during the 2012/13 crop season, in a Red Eutrophic Oxisol (Eutrudox) in no-tillage under irrigation. The experimental design was a randomized block with split plots with four replicates, totaling 120 subplots sized in 25m2 each. The plots consisted of the cropping systems prior to common bean: maize, maize/ U. ruziziensis intercropping and U. ruziziensis. The subplots were composed of ten top-dressing N fertilization splitting schemes (NS) at the phenological stages V3, V4 and R5 in different combinations. Common bean grain yield differs among cropping systems and as a function of top-dressed N split application. U. ruziziensis grass as single crop promotes greater N accumulation in common bean shoots compared to maize and its intercropping with U. ruziziensis grass. Regardless the cropping system, top-dressing N application in a single dose (90 kg ha-1) at V4 leads to similar accumulations and exports to those found in the absence of N fertilization. Splitting schemes with N application at the R5 stage increase the exports of this nutrient by common bean in succession to maize and its intercropping with U. ruziziensis grass.

An experiment was conducted during 2012-13 and 2013-14 at Ludhiana, Punjab to find out the productivity and profitability of the cotton-wheat cropping system as influenced by complex fertilizers. The experiment was comprised of nine fertilizer treatments. The results demonstrated that significantly higher cotton yield and stalk yield was recorded under T9 -AP60+S15+Zn1.5 (15.3 q/ha and 50.5 q/ha respectively in 2012 and 22.2 q/ha and 55.6 respectively in 2013) which was statistically at par with T6 – DAP (P60)+S15+Zn1.5 (15.0 q/ ha and 50.4 q/ha respectively in 2012 and 22.1 q/ha and 55.4 q/ha, respectively in 2013). Similarly in wheat crop, T9 -AP60+S15+Zn1.5 gave significantly higher grain yield and straw yield (39.0 q/ha and 63.0 q/ha, respectively in 2012-13 and 45.6 q/ha and 73.6, respectively in 2013-14) which was comparable with T6 – DAP (P60)+S15+Zn1.5 (38.5 q/ ha and 62.8 q/ha respectively in 2012-13 and 44.4 q/ha and 72.4 q/ha in 2013-14) as compare to other treatments. Economic analysis indicated higher net return (₹ 8739.0) and B:C ratio (0.37) for cotton under T8- AP30+S7.5+Zn0.75 whereas T9 -AP60+S15+Zn1.5 net return (₹14417.5) and B:C ratio (1.07) for wheat as compare with other treatments.

The Cost

Rice-wheat production is an essential component of cropping systems in the Indus-Ganga Plains (IGP) which play a pivotal role in food security of south Asia. These crops are being cultivated on an area of about 13.5 M ha of South Asia. In rice-wheat cropping system, the major reason for lower wheat grain yield is use of unwise tillage practices during wheat seedbed preparation, cultivation of late maturing rice varieties, water shortage, labor shortage, high cost of fertilizers and poor crop management practices. Resource-conserving technology improves the sustainability and productivity of wheat, which ultimately increase the farmer’s livelihood and reduce poverty. Tillage plays an important role in agricultural operation for soil manipulation to optimize the crop productivity. Different tillage systems are being practiced for wheat production in rice-wheat cropping systems including intensive tillage system, conventional and deep tillage, conservation tillage that consisting of minimum tillage, ridge tillage, and no-till or zero tillage system. Zero tillage gives more accessible and efficient planting system that ensures timely wheat cultivation, cut off the tillage operation, better crop residue management that ultimately minimize the cost of production and keeps environment clean. Operational costs for wheat sowing are 50-60% lower with zero tillage (ZT) sowing than with conventional sowing. The cost saving effect is the main reason for the spread of zero tillage technology in rice-wheat system. Current paper presented a review of different tillage systems and their effects on soil physical properties, plant available water, soil organic matter and nutrients, rice residues, wheat yield and farmer’s economics.

Three experiments were conducted in Lewiston, NC, from 1999 through 2002 to evaluate the influence of various application timings of flumioxazin preplant (PP) and postemergence-directed spray (PDS) on cotton injury. In experiment 1, flumioxazin was evaluated in a reduced-tillage system at 71, 105, or 140 g ai/ha in mixture with glyphosate, applied at 28, 14, or 7 d before planting (DBP), followed by irrigation at cotton emergence. Flumioxazin applied PP at any rate and irrigated at emergence injured cotton less than 7% at 2 wk after emergence (WAE) and less than 6% 5 WAE. In experiment 2, flumioxazin was evaluated in a conventional-tillage system at 71 or 105 g/ha as a PDS treatment applied to dry soil, wet soil, and dry soil irrigated immediately after application when cotton was 20 to 30 cm height. Cotton treated with flumioxazin PDS at either rate applied to dry soil, wet soil, or dry soil followed immediately by irrigation was not injured. In the third experiment, flumioxazin at 71 g/ha alone or in mixture with glyphosate at 1.12 g/ha was applied at 30, 21, 14, and 0 DBP in a conventional-tillage system. Flumioxazin applied alone or in mixture with glyphosate applied at any time did not injure cotton. In all experiments, cotton lint yields were not influenced by herbicide treatment.
