The Impact

Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility, reduced crop productivity, and grower’s income. Phosphorus (P) and zinc (Zn) deficiencies are considered important nutritional constraints under rice-wheat cropping system. One strategy to increase crop productivity and grower’s income under the rice-wheat system is the balanced application of P and Zn fertilizers. The objective of this research was to evaluate the impact of sole and various combinations of P (0, 40, 80, and 120 kg ha−1) and Zn levels (0, 5, 10, and 15 kg ha−1) on productivity (grain yield and yield components) and profitability (net returns) of different rice genotypes (cultivars) (fine (cv.Bamati-385) vs. coarse (cv. Fakhre-e-Malakand and cv. Pukhraj)) and their residual effect on the income of the succeeding wheat crop (cv. Siran-2010). The results revealed that both rice and wheat productivity and profitability was higher with the combined application of both nutrients at higher rates (80 and 120 kg P ha−1 and 10 and 15 kg Zn ha−1). The highest productivity and profitability was obtained with the cultivation of hybrid rice “Pukhraj” (Pukhraj > Fakhre-e-Malakand > Basmati-385). It was concluded from this study that application of higher P and Zn levels and growing of hybrid rice increased productivity and profitability under the rice-wheat cropping system.

Aims: To investigate the direct and residual effect of boron application on yield and nutrient content under rice-wheat cropping system in middle Gangatic alluvial plan. Study Design: Completely random design (CRD). Place and Duration of Study: Net-house of the Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India during 2017-18. Methodology: The pot experiment was comprised with ten treatments among them eight for boron (ranges from 0.5 to 4.0 mg B kg-1) along with control and recommended dose of fertilizer (RDF). Rice (Oryza sativa L.) variety ARIZE 6444 was used as test crop and after harvesting of rice crop, wheat (Triticum aestivum L.) variety HUW 468 was grown in the same pot without fresh application B. The yield data was recorded after harvesting of rice and wheat. The nutrient content in grain and straw and post-harvest soil properties were analyzed using standard protocol. Results: The maximum grain yield in rice (44.07 g pot-1) was recorded in T5 (RDF + 1.5 kg B ha-1), whereas in wheat (19.70 g pot-1) was observed in T8 (RDF + 3 kg B ha-1). The maximum straw yield in rice (24.35 g pot-1) was recorded in T5 (RDF+ 1.5 kg B ka-1), whereas in wheat (48.65 g pot-1) was in T8 (RDF + 3 kg B ha-1). Application of RDF along with 1.5 kg B ha-1 was recorded the maximum (48.99%) harvest index in rice, whereas its (B) residual effect in wheat crop was maximum in RDF + 2 kg B ha-1. Application of B @ 1.5 kg B ha-1 significantly enhanced the Fe, Cu, Mn and Zn content in rice grain, whereas residual effect of 3 kg ha-1 B application has significantly improved the Fe, Cu and Mn content in wheat grain. Conclusion: It was found that application of B did not increased grain yield of rice and wheat significantly over RDF. A significant residual effect of B application in rice was noticed even after the harvest of wheat crop particularly at highest doses of B application.

Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) in IGP deplete soil fertility and crop productivity. In order to maintain or enhance the sustainability of this system use of crop residues and biological formulation of microbes will be play an important role in this areas. Field experiment was conducted in rabi seasons of 2013-14 and 2014-15 at New Delhi, India to study the effect of microbial inoculated rice residue and N management on growth, productivity and economics of wheat under rice–wheat cropping system (RWCS). After rice harvest in both years, wheat variety “HD-2967” was grown on the same layout with applied treatments. Results of this experiment revealed that composting inoculated (CI) paddy straw mulch were recorded significantly higher effective tiller, spike length, spike weight, 1,000-grain weight(test weight) and yield during both the years. However, 100% RDN + Azotobacter (Liquid) was found maximum with regard to all yield and yield attributes characteristics. On economic comparison application of composting inoculated PSM with 100% RDN + Azotobacter gave maximum gross return and net returns.

The Impact

Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and reduce crop productivity as well as zinc (Zn) concentrations in rice grains and straw. Low Zn concentrations in rice grains have a negative impact on human health, while low Zn concertation in rice straw creates a nutritional problem for animals. The current high yielding rice varieties and hybrids remove large quantities of Zn from the soils, lowering the residual concentrations of soil Zn for the subsequent crop (e.g., wheat). Field experiments were conducted on farmers field in Malakand with the objective to evaluate the impact of various combinations of phosphorus (0, 40, 80, and 120 kg ha−1) and Zn levels (0, 5, 10, and 15 kg ha−1) on biofortification of Zn in grains and straw of rice genotypes [fine (Bamati-385) vs. coarse (Fakhre-e-Malakand and Pukhraj)]. The results revealed that Zn biofortification in rice genotypes increased with the integrated use of both nutrients (P + Zn) when applied at higher rates (80 and 120 kg P ha−1, and 10 and 15 kg Zn ha−1, respectively). The biofortification of Zn in both grains and straw was higher in the coarse than fine rice genotypes (Pukhraj > Fakhre-e-Malakand > Basmati-385). It was concluded from this study that the application of higher P and Zn levels increased Zn contents in rice parts (grains and straw) under the rice-wheat system. We also concluded from this study that Zn concentrations in rice grains and straw are influenced by plant genetic factors and Zn management practices.

A field experiment was conducted during Kharif and rabi seasons of 2015 and 2016 at farmer’s field of Banka District as an On Farm Trial to study the crop residues management with different crop establishment methods in rice (Oryza sativa L.)–wheat (Triticum aestivum L.) cropping system. Treatment comprised two levels of crop residue management ie. residue removal and residue retention (33%) and three levels of crop establishment methods ie. (a) conventional puddled transplanted rice fb conventional-till wheat (PTR-CTW), two times ploughing with cultivator followed by two times puddling and one planking was done before the manual transplanting of 21 days old seedling at 20 cm spacing from row to row. After rice harvesting, wheat was sown by broadcasting in conventional tillage plots with two times harrowing with cultivator followed by one planking; (b) unpuddled transplanted rice fb zero-till wheat (UPTR-ZTW): two times ploughing with cultivator followed by planking, after that water is submerged for transplanting and wet tillage was avoided. 21 days old rice seedlings were transplanted at a spacing of 20 x 15 cm. Wheat crop was sown under ZT using zero tillage machines; (c) zero-till direct-seeded rice fb zero-till wheat (ZTDSR-ZTW): direct-seeding of rice was done using zero-till seed-cum-fertilizer drill in ZT-flat plots at 20 cm row spacing. Wheat crop was sown in zero tillage using zero till machine. Rice variety (Rajendra Sweta) was sown directly by zero till in ZTDSR-ZT plots in the first fortnight of June. On the same date, rice seedlings for transplanting were raised in nursery by ‘Wet bed method’. Experiment was conducted in a split plot design which is replicated by thrice. Grain/panicle or spike, panicle or ear length and effective tillers/m2 recorded more in residue retention treatment and it was registered significantly superior with residue removal treatment under crop residue management in rice and wheat crop during both the years of experiment. Amongst crop establishment method, ZTDSR-ZTW was recorded more Grain/panicle or spike, panicle or ear length and effective tillers/m2 and it was significantly superior with UPTR-ZTW and PTR-CTW treatments under crop establishment methods in rice and wheat crop during both the years of experiment. Residues retention (33%) significantly improved the grain yield of both the component crops. For rice crop, 8.2–10.0% higher grain yield was realized with retention of crop residues. Grain and straw yield of rice were registered more in ZTDSR-ZTW (3.86-3.99 t/ha) & (5.56-5.75 t/ha) closely followed by UPTR-ZTW (4.38-4.45 t/ha). Concerning the data of residue management on economics revealed that the residue retention was recorded more gross return, net return as well as B: C ratio followed by residue removal treatment in both years of experimentation for rice and wheat crop and ZTDSR-ZTW was recorded more gross return, net return as well as B: C ratio followed by UPTR-ZTW and PTR-CTW treatments under crop establishment methods in rice and wheat crop during both the years of experiment.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.

The Impact

Under the rice–wheat cropping system (RWS), the continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility, and reduce crop growth and total rice biomass. In RWS, both phosphorus (P) and zinc (Zn) deficiencies are considered important nutritional constraints for reducing rice crop growth rates (CGR) and total biomass/biological yield (BY). The objective of this experiment was to investigate the impact of phosphorus (0, 40, 80, 120 kg P ha−1) and zinc rates (0, 5, 10, 15 kg Zn ha−1) on CGR and BY of three rice genotypes [fine (Bamati-385) versus coarse (Fakhre-e-Malakand and Pukhraj)] in Northwestern Pakistan during summer 2011 (Y1) and 2012 (Y2). The results revealed that higher CGR at various growth stages and total BY was obtained with the integrated use of higher phosphorus (80 and 120 kg P ha−1) and zinc rates (10 and 15 kg Zn ha−1). The lower CGR and BY were recorded when P and Zn were not applied (control) or when P and Zn were applied alone. In the case of rice genotypes, the highest CGR and BY were recorded for the hybrid rice (Pukhraj) than the other two genotypes. The CGR was increased to the highest level at the heading stage as compared to tillering and physiological maturity. The increase in CGR had a positive impact on the total BY of rice cultivars. The increase in BY had a positive relationship with grain yield and grower’s income. It was concluded from the study that the combined application of higher P and Zn rates to the coarse rice genotypes (Fakhre-e-Malakand and Pukhraj) could increase CGR, total BY, crop productivity and profitability.

Field experiments were conducted at the Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar during 1996/97 and 1997/98. Each experiment comprised 10 crop sequences: (a) wheat–rice, (b) chickpea–rice, (c) lentil–rice, (d) pea–rice, (e) wheat–mungbean green manure–rice, (f) wheat–Sesbania green manure–rice, (g) wheat–fodder–rice, (h) chickpea–fodder–rice, (i) lentil–fodder–rice and (j) pea–fodder–rice, in a randomized block design with four replications. The crop sequences were compared in terms of economic rice equivalent yield (REY), protein production, apparent nutrient balances and effect on soil fertility status. Amongst crop sequences involving two crops each year (200% cropping intensity), chickpea–rice gave highest REY and protein production. Of the sequences involving three crops each year (300% cropping intensity), chickpea–fodder–rice and wheat–fodder–rice were superior to others. The P balances were positive for all sequences, whereas K balances were generally negative except for sequences involving green manure legumes. Green manuring with Sesbania or mungbean helped restore soil fertility, indicating the advantage of green manure for higher productivity and sustainability of rice–wheat system. Chickpea–rice and chickpea–fodder–rice appeared promising alternatives to rice–wheat crop sequence.

The Impact

Rice (Oryza sativa L.) is the second most important crop in the world after wheat and also the most important crop in Nepal. The production of rice is influenced by various biotic and abiotic factors. Temperature is the major constraint for the crop yield. The present experiment was conducted to study the impact of temperature on straw and crop productivity from June to October 2014. The experiment was conducted under temperature control chamber, in which temperature was elevated from the ambient level by 2ºC and 3ºC for the entire crop growth period. Grain and straw yield was measured using electronic weighing machine. Maturity of grain was 10 and 7 days earlier at elevated temperature by 3ºC and 2ºC respectively. Under similar condition of water depth, plant spacing, rice variety and soil nutrient, rise in temperature up to 2ºC is favorable for rice straw yield and crop productivity. Yield loss under elevated temperature by 3ºC is due to floret sterility. Further research on temperature resistance rice variety is necessary.

The utilization of organic fertilizers in farmlands to enhance crop productivity and soil health is increasing globally. Compost and charcoal obtained from the decomposition and slow pyrolysis (respectively) of plants and animals wastes. Here we evaluated the effect of charcoal and compost on the growth and yield of wheat (Triticum aestivum L.) at Agriculture Research Farm Peshawar, Pakistan during 2014-2015. Results showed that the application of compost and charcoal as sole or in combination significantly affected the yield and yield attributes of wheat. Data divulged that the maximum numbers of plant tillers (337 m-2), number of productive tillers per plant (313 m-2), number of grains per spike (56 spike-1) and 1000 seeds weight (50.2 g) were produced by the combined application of compost and charcoal at 5+5 Mg ha-1 while plant height (95.3 cm) was enhanced with the application of charcoal at 10 Mg ha-1. The gain (4106.7 kg ha-1) and biological yield (8473.3 kg ha-1) was significantly increased with the compost application at the rate of 10 Mg ha-1. These results proved that charcoal and compost can be used as organic fertilizers for boosting growth and yield performance of wheat under the agro-climatic conditions of Peshawar, Pakistan.
