Agronomic Management

Rice (Oryza sativa L.)-wheat (Triticum aestivum L. emend. Fiori and Paol.) is the most important two crops a year intensive rice based cropping system of Asia. Agronomic management is the most important input for getting potential yield and high net returns in any crop or crop sequence. Most of the farmers used to grow old varieties of rice and wheat without any row arrangement. Fertilization is mainly limited to nitrogenous fertilizer only. Therefore, the present study was undertaken to find out the effect of different agronomic management practices on productivity and economics of rice-wheat system at farmers’ fields. Inclusion of improved variety in rice and wheat incurred additional cost of $52/ha and provided additional return of $101/ha, whereas sowing/transplanting of rice and wheat in lines incurred additional cost of $30/ha and resulted in additional returns of $146/ha. Balanced fertilization incurred additional cost of $38 over the imbalanced fertilization and provided additional returns of $180/ha. Recommended package of practices (improved variety, line sowing/transplanting and balanced fertilization) incurred additional cost of cultivation of $120/ha over the farmers’ practice and achieved additional net returns of $426/ha.

Rice (Oryza sativa L.) is first staple crop of Nepal. The national average yield of rice is less than its potential yield, for which poor agronomic management has been reported as the critical factor. Among various agro-management practices seedling age, seeding density and nitrogen rates significantly affect the growth and yield of rice. The lower seeding density produces the taller plant, more effective tiller, lower sterility and higher grain yield. On the other hand, seedling of older age from higher seeding density gives the lowest yield. Transplanting younger seedling with low seeding density and application of recommended dose of nitrogen gives a higher yield. This article summarizes various effects of seedling age, seeding density and nitrogen rates on plant height, number of effective tillers, number of filled grains, thousand grain weight and grain yield of rice. This information may be useful for maize growers and researchers.

Residue Retention

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.

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.

High Rainfall

Average yield of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) in the high rainfall cropping zone (>750 mm) of south Western Australia from 1996 to 2001 was 2.5 t/ha. This is far below the water-limited potential yield (water losses of 110 mm, transpiration efficiency of 20 kg/ha.mm) of 6–8 t/ha. Nutrition of the cereal crops has been regarded as one constraint to reaching the potential yield, although grain yield increases (responses) under conventional management practices (a series of full cultivation operations) have been inconsistent. Three experiments, with a total of five trial sites conducted over two seasons, were carried out to test the response of wheat and barley to fertiliser applications of nitrogen (N), phosphorus (P), potassium (K), sulfur (S) and trace elements (TE). Various combinations of nutrients were applied. These ranged from no fertiliser (nil), to farmer practice (N at rates at 34–82 kg/ha, P at 3–17 kg/ha, K at 0–50 kg/ha and S at 4–11 kg/ha), to nutrients calculated to supply the needs of a 6–8 t/ha cereal crop (N, P, K, S, TE). The aim was to determine whether the supply of non-limiting levels of crop nutrients could raise yields to the potential yield as determined by seasonal rainfall. In the drier seasons experienced in 2001 and 2002 at Arthur River and Cranbrook, with growing season rainfall (May–November) up to about 350 mm, it was possible to raise grain yields to levels at or above the calculated rainfall-limited potential with increased nutrition (4.2 t/ha for barley and 4.5 t/ha for wheat). However, in the wetter environment of Boyup Brook in 2002, where seasonal rainfall was greater than 500 mm, extra nutrition by itself was not sufficient to reach the water-limited potential, even where the yields were increased from 3.5 to 5.2 t/ha for wheat and from 3.9 to 4.5 t/ha for barley. Further experimentation is required to clarify the factors limiting responses to nutrition when the growing season rainfall is greater than 500 mm and thus allow greater confidence in extrapolating these results in the high rainfall cropping zone of Western Australia. In wheat, the highest profits were obtained from the complete fertiliser strategy (N, P, K, S, TE). However, for barley, the greatest profits were not obtained with the highest grain yields and fertiliser strategies due to decreased grain quality.

Chlorophyll Formation

The productivity of sesame is mainly dependant on proper agronomic management practices including nutrient management. In oilseeds, sulphur plays a prominent role in the synthesis of essential oils, chlorophyll formation and gives pungency in oil. It is also increasing drought and cold resistance of oilseed crops. Hence, field studies were conducted for two consecutive years to study the effect of various sources of sulphur (Gypsum and Sulphur Bentonite) and their different levels (15, 30 and 45 kg S ha-1) on growth, yield and economics of sesame. Studies revealed that, irrespective of sources of sulphur seed yield increased progressively with increase in sulphur dose from 15 to 45 kg ha-1 and the increase was significant at 45 kg ha-1 over 15 kg ha-1and control. Application of sulphur at 45 kg/ha through gypsum produced significantly higher plant height (97.1 cm), branches/plant (4.98), capsules/ plant (95.9) and seed yield (586.5 kg/ha) than at 15 kg S/ha through gypsum, Sulphur bentonite and recommended NPK and remaining at par with application of Sulphur at 30 kg/ha. Sulphur application at 45 and 30 kg ha-1 through gypsum recorded significantly higher net returns (Rs. 33365 and 31963 ha-1 respectively) and B: C ratio (2.47 and 2.38 respectively) than Sulphur Bentonite and recommended NPK during both the years.

A field experiment was conducted to evaluate the effect of land management practices and residual effect of nutrient management practices of rice on the performance of subsequent wheat crop in the rice-wheat cropping system in Agriculture and Forestry University (AFU), Rampur, Chitwan, Nepal during June 2018-March 2019. The experiment was executed in a split-plot, included two establishment methods viz. (i) conventional tilled dry direct-seeded rice followed by (fb) zero tillage wheat (CT-DDSR fb ZT) (ii) puddled transplanted rice followed by conventional tillage wheat (Pu-TPR fb CT) as main plot treatments, and four nutrient management practices: (i) 100% recommended dose (100% RDF; 150:45:45 and 80:60:40 kg N, P2O5, and K2O ha-1 respectively for rice and wheat), (ii) Residue retention @ 5 t ha-1 of wheat on rice fb residue of rice on wheat + 75% RDF of each crop (RR +75%RDF), (iii) Nutrient expert (NE) dose (140:56:53; 140:60:45 kg N, P2O5, and K2O ha-1 for rice and wheat respectively), (iv) Brown/green manuring of Sesbania in rice fb rice residue @ 3.5 t ha-1 in wheat +75% RDF of each crop (BM/GM fb R+75% RDF) as subplot treatments with three replications. The variety of wheat ‘Bijay’ was sown @120 kg ha-1 with spacing 20 cm × continuous. The data on phenology, yield, yield attributes, and economics were recorded and analyzed by R studio. The study revealed that none of the yield attributes and yield of wheat were significantly influenced by the establishment methods. Significantly more effective tillers (281.94 m-2) and grains per spike (44.48) and higher straw yield (5.95 t ha-1) were recorded under NE dose. The grain yield of wheat was 21% and 16% more under NE dose and BM/GM fb R+75% RDF respectively compared to 100% RDF. CT-DDSR fb ZT wheat had slightly less net returns (NRs. 4523 ha-1) than Pu-TPR fb CT-wheat. NE dose was the most profitable. Hence, rice establishment methods were indifferent but NE dose was the best nutrient management practice for better production and profitability for the wheat in the rice-wheat system.

Aim: Blackgram is one of the most important pulse crops raised in several types of soil under well drained conditions. Currently, it is cultivated as monocrop , intercrop as well as rice fallow crop in southern India. When the rice fallow pulse systems are described as, the pulse crop is seeded before or after rice harvest without ploughing, the remaining soil moisture may be better used through conservation agriculture measures. It's also known as a relay crop, a no-till crop, or a residual crop.In general, the production and productivity of black gram is declining because of poor management practices . Thus, this study was undertaken rice establishment methods as a strategy to determine the availability of residual moisture on the establishment of rice fallow black gram system during the early growth stages. Place and Duration of Study: A field investigation was carried out at Agricultural College and Research Institute, Madurai (Tamil Nadu Agricultural University9o54’ N Latitude, 78o54’ E Longitude with an  altitude of 147 m above MSL), Tamil Nadu, India from September 2019 to April 2020 Methodology: To see how different seeding methods and time influence the rice fallow black gram, the factors include rice planting methods as the main plot, methods of sowing black gram on rice fallow black gram as  sub plot, and time of sowing black gram on rice fallow black gram given out in sub-sub plot treatment. Results: The treatments had the best growth qualities, growth analysis, and yield. It could be because the above-mentioned combinations had higher residual moisture content, which resulted in a higher germination percentage, better crop stand, and higher growth and yield of rice fallow black gram. Conclusion: The best management strategy is to sowing black gram in rice fallow situations with a rice fallow pulse planter at 10 days before rice harvest, under the direct seeded of rice establishment technique with drum seeder.
