“…The lower energy efficiency index was observed in the treatment combination AR+SSB+POE (3.44), which might be due to the higher energy input and lowest grain yield obtained from the respective treatment. This conclusion is consistent with those of Bohra and Kumar (2015). The energy intensiveness was observed to be lower in the treatment combination SRI+ W F and SRI+ PE+CW (0.10 MJ/Rs).…”

Background: SRI and aerobic rice are one of the techniques of growing rice under water scarcity areas where meeting water requirement is becoming a global threat. Weeds are another threat to yield of rice irrespective of different establishment methods. Until checked, it can decline rice yield and quality up to more than 70%. SRI and aerobic rice have different densities of weeds and integrated weed management can be applied to suppress the weeds. Considering the current scenario, research was conducted to investigate growth, yield and bioenergetics of rice under different establishment methods and weed management. Methods: The experiment entitled “Effect of crop establishment methods and weed management practices on productivity and bioenergetics of rice” was carried out in split plot design with main plots, viz., M1- aerobic rice (AR) and M2- system of rice intensification (SRI) and five subplots W1- pre-emergence (pendimethalin @1 kg a.i ha-1) fb post-emergence (bispyribac-sodium @20g a.i ha-1) (PE+POE), W2- pre-emergence (pendimethalin @1 kg a.i ha-1) fb cono weeding at 15, 30, and 45 DAT/ DAS (PE+CW), W3- weed free (WF), W4- weedy check (WC), W5- stale seedbed followed by post-emergence herbicide (bispyribac-sodium 10% SC 20 g a.i ha-1) (SSB+POE) in split plot design with three replications taking the variety ‘Pusa Basmati-1121’ as a test crop. Result: Among the establishment methods, SRI recorded significantly higher growth attributes like plant height and dry matter production and yield attributes like number of panicles per hill, panicle length, number of grains per panicle, test weight, grain yield, straw yield, biological yield, and harvest index. Among the weed management treatments, WF recorded significantly higher growth attributes like plant height, number of tillers per hill, dry matter production and yield attributes like number of panicles per hill, panicle length, number of grains per panicle, test weight, grain yield, straw yield, biological yield, and harvest index that was followed by treatment PE+CW. Maximum net return and B:C ratio was observed in the treatment combinations M2W2- SRI + (PE+CW). The maximum total energy input was found in the treatment combination M1W1- AR+ (PE+POE) and the maximum total energy output was found in the treatment combination M2W3- SRI + WF. The energy intensiveness was observed to be maximum in the treatment combination M1W4- AR + WC and the maximum energy efficiency index was observed in the treatment combination M2W3- SRI+WF.

“…The DSR based rice-groundnut cropping system (Table 3) fetched higher gross returns (`240.4 × 10 3 /ha), net returns (`97.2 × 10 3 /ha), benefit:cost ratio (1.71) and profitability (`266.4/ha/day) over TPR owing to lower cost of cultivation (man-days) and higher system yield. The results confirm the findings of Bohra and Kumar (2015). Organic sources of nutrient to rice resulted in higher cost of cultivation of the system due to higher cost of organic manures.…”

A field experiment was conducted during the rainy (kharif) and winter (rabi) seasons of 2019–20 and 2020–21 at the Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, to study the effect of different riceestablishment methods and nutrient management on yield, economics and soil properties in rice (Oryza sativa L.)– groundnut (Arachis hypogaea L.) cropping system. The experiment was laid out in a split-plot design with 3 replications. Six treatment combinations, comprising of 2 rice-establishment methods, viz. direct-seeded rice (DSR) and transplanted rice (TPR) and 3 levels of nutrient-management practices, viz. inorganic-100% soil test-based fertilizers (STBF), organic-dhaincha [Sesbania aculeata (Wild.) Pers.] green manuring +1/3rd soil test-based nitrogen (STBN) through vermicompost @2 t/ha + 1/3rd STBN through neem oil-cake @ 0.87 t/ha and integrated nutrient management (INM), viz. green-manuring + 50% STBN (inorganic @ 50.0 kg N/ha) + 100% P2 O5 + 100% K2 O, in rice during kharif were allotted to the main-plots. Three nutrient-management practices to groundnut during rabi, viz. 75% STBF, 100% STBF and 75% STBN (inorganic) + 25% STBN through FYM @ 1.63 t/ha + 0.2 lime requirement @ 0.38 t lime/ha + biofertilizers (Rhizobium + phosphate-solubilizing bacteria) + 100% P2 O5 + 100% K2 O, were allotted to the sub-plots. Transplanting of rice (TPR) increased the yield parameters of rice, resulting in 3.3% higher grain yield (5.65 t/ha) than direct seeding of rice. The INM improved the yield parameters of rice, resulting in 13.3 and 15.2% increase in grain yield over sole inorganic and organic practice, respectively. Carryover effect of the DSR on succeeding groundnut crop improved the yield attributes and resulted in 15.8% higher pod yield (2.49 t/ha) than the groundnut crop grown after TPR. Residual effect of organic nutrient management in rice crop enhanced the yield parameters of succeeding groundnut, resulting in 4.2 and 16.5% higher pod yield than the groundnut grown after INM and inorganic practice in rice, respectively. The INM practice in groundnut increased its yield parameters, resulting in 11.4 and 18.1% higher pod yield over 100% and 75% STBF, respectively. The DSR enhanced the system yield (12.51 t REY/ha) of rice-groundnut cropping system by 6.8% over TPR. The INM practice in rice crop enhanced system yield by 12.6 and 4.2% over inorganic and organic practice, respectively. Similarly, INM to groundnut crop resulted in 7.4 and 11.2% higher system yield than 100% and 75% STBF, respectively. The DSR, INM practice in rice and INM practice in groundnut crop fetched higher gross returns (`240.4 ×103 /ha, 245.5 ×103 /ha and 247.0 ×103 /ha), net returns (`97.2 ×103 /ha, 108.9 ×103 /ha and 92.7 ×103 /ha), benefit: cost ratio (1.71, 1.80 and 1.62) and system profitability (`207.9, 298.5 and 254.1/ha/day). Organic management under DSR and INM in groundnut improved the physico-chemical and biological properties of soil.

“…Grain and straw yield of rice and wheat: The grain (4.23 and 4.42 t/ha) and straw yields (7.61 and 7.67 t/ha) in transplanted rice were significantly higher than aerobic rice (3.48 and 3.67 t/ha of grain yield; 6.73 t/ha and 6.79 t/ha of straw yield) in both the years of rice cultivation (Fig 1). It might be due to the adequate availability of water and nutrients and weed free conditions that favoured good crop growth and ultimately led to higher yield in conventional transplanted rice (Gouda et al 2021).…”

A field experiment was conducted during rainy (kharif) and winter (rabi) seasons 2019–20 and 2020–21 at the research farm of ICAR-Indian Agricultural Research Institute, New Delhi to study the effect of rice establishment techniques (RETs) and microbial consortia mediated in situ rice residue management options on nitrogen (N) budgeting in a rice (Oryza sativa L.)-wheat (Triticum aestivum L.) cropping system (RWCS). The experiment was laid out in split plot design with 3 replications having 2 main plot treatments, viz. aerobic rice (AR) and conventional transplanted rice (CTR) in kharif and 7 sub plot treatments, viz. clean cultivation (removal of paddy straw), paddy straw incorporation, paddy straw mulching, paddy straw incorporation + Pusa decomposer, paddy straw mulching + Pusa decomposer, paddy straw incorporation + urea @20 kg/ha, paddy straw incorporation + Pusa decomposer + urea @10 kg/ha. The residual effects of these treatments were observed in seed drill and zero till sown wheat in rabi seasons. Results showed that N uptake (95.1 kg/ha and 100.4 kg/ha in CTR and 79.4 kg/ha and 83.8 kg/ha in AR) was significantly superior in CTR than AR in kharif seasons. The residual effects of in situ rice residue management options in wheat, paddy straw incorporation + Pusa decomposer + urea @10 kg/ha resulted in significantly higher N uptake (136.4 and 141.5 kg/ha) than other treatments, and it was followed by paddy straw incorporation + Pusa decomposer in both the years. The nutrient uptake by the RWCS was an important indicator of soil fertility and plant nutrient status. This investigation concluded that there is need for use of microbial consortia mediated in situ rice residue management in RWCS for positive N balance in spite of enhanced nutrient uptake.
