Residue Retention

The rice–wheat cropping system being the backbone of food security in South-Asia has resulted in soil health deterioration, declining water table, and air pollution affecting livability index of the region. The effect of rice residue retention (RRR), irrigation levels and foliar application of K on wheat grain yield (GY), water use efficiency (WUE) and profitability was tested over three years. RRR increased wheat GY (5224 kg ha−1), above-ground biomass (AGBM = 11.9 t ha−1), tillers per square meter (TPM = 469) and grains per meter square (GrPMS = 13,917) significantly. Relative water content (RWC = 93.8) and WUE (2.45 k gm−3) were also increased significantly by RRR. Consequently, profitability (Net return = 624.4 $ and Benefit to cost (B:C) ratio) was enhanced. Foliar application of K enhanced GY (5151 kg ha−1), AGBM (12 t ha−1), RWC (94.1), SPAD (52.2), WUE (2.40 kg m−3), net returns (625.2 $) and BC ratio (1.62) significantly. RRR increased GY (15.66%) and WUE (17.39%) with additional revenue of 151 $ with only one irrigation at the CRI stage (ICS). RRR adopted over 10% of the area can earn 187 million-US$ annually. RRR if adopted over existing practice on a large area would reduce environmental degradation with an enhanced income to small and marginal farmers.

SUMMARYAn experiment is desoribed which was conducted for 2 years under dryland conditions of north-west India to evaluate the optimum rate of application of N fertilizer and plant population density for a rapeseed crop. Stomata closing (phenyl mercuric acetate), film forming(Mobileaf) and reflective type (kaolinite) antitranspirants were used to examine their effectson conservation of stored moisture for a possible increased water use efficiency under drylandconditions.The rapeseed crop responded to N fertilizer and it was profitable to use 53 kg N/ha xinder these conditions. In a drier year a wider row spacing of 60 cm (1·1 x 106 plants/ ha) was significantly better than narrower spacing of 30 cm (2·2 xlO5 plants/ha). Plants grown in wider row spacings utilized less water during the vegetative and flowering stages than those grown in closer spacings.The relative water content of leaves sprayed with antitranspirants was greater than in the control plants. The leaf temperature of the kaolinite-treated canopy was 1·5 °C lower than the ambient air temperature. Averaged over 2 years, the film-forming antitranspirant Mobileaf increased the seed yield by 26% while spraying with phenyl mercuric acetate at 50 and 75 days and kaolin application at 50 days increased the rapeseed yield by 11, 18 and 17% over the no antitranspirant treatment.

I Intensively practices rice-wheat (R-W) cropping system (RWCS) in South-Asia is suffering from many sustainability issues such as micronutrient deficiencies, labour scarcity, production cost, declining land, declining groundwater level and water productivity along with declining soil health.  Climate change further complex the things in one or other way. Therefore, the intervention of climate smart technologies are urgent for improving water productivity in an enormous water use RWCS of South-Asia. Although, farmers are confused regarding picking of suitable climate smart technology (CST) viz., laser land leveling, un-puddled direct-seeded rice (UPDSR), soil matric potential based irrigation, double zero tillage in wheat followed by rice, raised bed planting, short duration cultivars and correct transplantation time, for enhancing their livelihoods through increasing land and water productivity on one side and mitigating global warming consequences on other. Performance of these technologies is both site and situation specific, and care must be taken in practicing them. Most of them cutting down the drainage losses, which further reduces recharging of soil profile which is not required in water stressed regions while these might be termed as energy-saving technologies; otherwise used to withdraw water from the deeper soil depths. These CST are also useful for waterlogged regions. However, CST viz. correct transplantation time and short duration cultivars partition higher fraction of ET water (evapotranspiration) from E (evaporation) to T (transpiration) component which further favour higher grain yields and thus, higher water productivity. Therefore, it is crucial for the introduction of CST for improving agricultural and water productivity in the era of climate change in an enormous water use RWCS of South-Asia.

A large area is available in the form of boundaries, bunds, block plantations, wastelands where this system can be adopted. Poplar and Eucalyptus are suitable and promising agroforestry tree species, which is planted cropping system. In this particular study, Economical aspects and viability of wheat and Mustard have been studied. Trees intercropped with crops attained better growth and higher litter. In the study of nutrients (NPK) it is reviewed that all the three nutrients increase as the age of trees increases. All the nutrients increases as the tree age are increased. It is clearly seen after the whole research work done, nutrients in the soil are high insole plantation of trees. The yield of intercrops is low in the fields which are cultivated along with trees. The height of intercrops is higher under Poplar than intercrops under Eucalyptus. This might be due to the leaf pattern and its canopy shade. No significant results were obtained for tillers per plant and effective tillers per plant in wheat, however, more tillers were found in pure cropping. In Mustard primary branches per plant and seeds per siliqua were at par under Eucalyptus, Poplar, and pure cropping. Yield parameters such as secondary branches per plant, siliqua per plant, and test weight were significantly higher in pure cropping. The grain and straw/stover yields of both the crops under Eucalyptus and Poplar decreased significantly as compared to open fields (crops without Eucalyptus and Poplar). Net returns from a crop grown with Eucalyptus, & Poplar and sole cropping revealed that maximum income (Rs.82819.00/ha) was recorded in pure cropping (monoculture) of wheat, whereas net returns from Mustard grown Eucalyptus, Poplar and sole cropping revealed that maximum income (Rs.67275.00/ha) and whereas negative net returns of Rs.3943.47/ha (under 4years Eucalyptus) and also negative net returns Rs. 8731.00/ha (under 5 years Poplar) was recorded in Mustard oil.

The research on productivity, energy-use efficiency and economics of pigeonpea based cropping system, viz., pigeonpea–wheat, pigeonpea – barley, pigeonpea – lentil, pigeonpea – field pea and pigeonpea – toria compared with rice–wheat cropping system was carried out at the Experimental Research Block of School of Agricultural Sciences, SGRRU, Uttarakhand. These cropping systems were evaluated under rainfed conditions. Results showed that all the pigeonpea – based cropping system were significantly superior to traditional rice – wheat cropping system in terms of productivity, net returns, benefit:cost ratio and net energy returns. Pigeonpea – lentil cropping system proved superior in terms of system net returns (Rs 63,616/ha), benefit:cost ratio (1.64) and energy ratio (1.94) to pigeonpea - wheat, pigeonpea – barley, pigeonpea - field pea and pigeonpea - toria cropping system. The plots under rice - wheat cropping system recorded the lowest pigeonpea-equivalent yield (1.32 t/ha), net returns (Rs 2,750/ha) and benefit:cost ratio (0.06). The nutrient status of the soil improved significantly due to pigeonpea – lentil cropping system over other cropping systems. Pigeonpea – lentil cropping system proved to be the best in terms of monetary returns, net energy return and soil productivity and hence, could be adopted in the mid-hill regions under rainfed conditions.

Direct Seeded

Direct-seeded rice (DSR) is a potent option for north-west India considering the current shortages of labour and water. The formation of a subsurface compact layer in medium to coarse textured soils due to continuous puddling used for commonly grown puddled, transplanted rice hampers the root growth of DSR and wheat crops. It is thus imperative to study the deep tillage effects on water balance and water productivity of the DSR–wheat cropping system. A two-year field experiment was conducted during 2016–17 and 2017–18 in a sandy loam soil to study the soil water dynamics in relation to tillage and irrigation regimes in a DSR–wheat cropping system. There were two irrigation regimes both in DSR (irrigation at 4-day and 8-day intervals) and wheat (based on irrigation water to pan evaporation ratio of 1.0 (I1.0) and 0.5 (I0.5)) in main plots; with three tillage treatments in subplots: (1) conventional tillage for both DSR and wheat (DSRCT-WCT), (2) deep tillage before sowing of DSR during the first season + conventional tillage in wheat (DSRDT1-WCT) and (3) deep tillage before sowing of DSR during both seasons + conventional tillage in wheat (DSRDT2-WCT). The irrigation water input was lower by 325 mm under 8-day, I0.5 compared with 4-day, I1.0 irrigation regimes during both years. The evapotranspiration (ET) was significantly higher in plots with the 4-day compared to 8-day irrigation regime by 22.8% and 17.2% during 2016 and 2017 respectively. In wheat, ET was significantly higher in plots with I1.0 than I0.5 by 42.7% and 34.8% during 2016–17 and 2017–18 respectively. The ET was significantly higher in DSRDT2-WCT and DSRDT1-WCT than DSRCT-WCT in DSR. The water productivity was higher in less frequently (8-day and I0.5) than in frequently irrigated (4-day and I1.0) plots. Deep tillage during both seasons (DSRDT2-WCT) had no significant influence on the soil water balance components and water productivity in comparison to deep tillage only once in two years (DSRDT1-WCT). However, the ET and water productivity were significantly higher in plots with deep tillage compared to conventional tillage.

Cotton Genotypes

SUMMARYCotton–wheat (CW) is an important cropping system in South Asia. Wheat yields under a conventional CW system are generally lower compared to a rice–wheat system due to delayed seeding. Relay seeding of wheat can help timely sowing, capturing residual soil moisture of last irrigation to cotton, and increase the productivity and profitability of CW system. The field experiment included two Bt-cotton genotypes having different canopy cover (RCH 776 and MRC 7017), two types of relay seeders (RSs) for cotton planted at 67.5-cm and 101-cm row spacing and four types of relay seeding methods (manual broadcast, strip rotor (SR) and zero-till double disc and conventional till). Relay planting of wheat allowed one additional boll picking, which increased seed cotton yield by 12% compared with conventional tillage wheat. Cotton genotypes and RSs had no effect on emergence and yield of wheat. The RSs with SR and zero till double disc furrow openers performed better in terms of wheat emergence and grain yield compared to zero-till tine openers. Under relay seeding, wheat sowing was advanced by 31 days, which increased grain yield by 18.8% compared with conventional tillage practice. Net returns from the CW system with relay seeding of wheat were higher by US$ 311 to 425 ha−1 compared with the conventional CW system.
