@article{Samant_Garnayak_Paikaray_2022, title={Improvement of Productivity, Agro-Meteorological Indices, Energetics and Nutrient Balance of Rice-Groundnut Cropping System}, volume={51}, url={https://banglajol.info/index.php/BJB/article/view/61994}, DOI={10.3329/bjb.v51i3.61994}, abstractNote={<p>Effects of two rice establishment methods namely, direct seeding (DSR) and transplanting (TPR) and three nutrient management practices in rice and three nutrient management practices in groundnut of rice (<em>Oryza sativa </em>L.)- groundnut (<em>Arachis hypogaea </em>L.) system were investigated. TPR produced 7.1 and 5.6% higher grain (5.75 t/ha) and straw (6.81 t/ha) yields than DSR with superior yield attributing characters. INM (green manuring + 50% STBN + 100% P<sub>2</sub>O<sub>5</sub> + 100% K<sub>2</sub>O) enhanced grain and straw yields of rice by 13.3 and 10.0% over inorganic (100% STBF) and by 15.2 and 8.2% over organic (green manuring + 1/3<sup>rd</sup> STBN through vermicompost + 1/3rd STBN through neem oil cake) management practices, respectively. INM practice in groundnut (75% STBN + 25% STBN (FYM) + lime 0.2 LR + biofertilizers (<em>Rhizobium </em>+ PSB) <strong>+ </strong>100% P<sub>2</sub>O<sub>5</sub> + 100% K<sub>2</sub>O) also produced the highest pod (2.74 t/ha) and haulm (3.62 t/ha) yield, which were, respectively, 39.8 and 5.5% higher over 75% STBF and 20.2 and 1.4% more than 100% STBF. But, DSR resulted in higher system yield (12.7 t REY/ha), system productivity (34.7 kg REY/ha/day), energy productivity and accumulated heat use efficiency than TPR system. INM practice in rice showed maximum system yield, productivity and P and K balance whereas, organic approach resulted in higher N balance. INM in groundnut produced the maximum system yield, productivity, HUE and N balance, but 75% STBF showed maximum agro-meteorological indices, P and K balance in spite of lowest system yield and system productivity. Energy productivity and efficiency were higher with 100% STBF in groundnut.</p> <p>Bangladesh J.
