The experiment was laid out in factorial randomized block design with three replications of each twenty treatment combinations consisting of four fertility levels and five secondary and micronutrient levels. Integrated nutrient management exhibited significant effect on growth, yield attributes and yield of baby corn. Application of 75 % RDF+vermicompost @ 2.5 t ha-1 +mixed bio-fertilizers recorded the highest plant height, number of leaves plant-1 , LAI , dry matter accumulation of baby corn at harvest along with yield baby corn (1.50 t ha-1) and green forage (26.03 t ha-1). Application of 40 kg S ha-1 +5 kg Zn ha-1 +2.5 kg B ha-1 has resulted in significant increase in yield components such as number of corns plant-1 , length and girth of baby corn, baby corn weight along with yield of baby corn (1.54 t ha-1) and green forage (26.17 t ha-1). The highest net return (` 77921 ha-1) and B: C ratio of 3.07 were registered in 75% RDF+vermicompost @ 2.5 t ha-1 + mixed bio-fertilizers. Application of 40 kg S ha-1 +5 kg Zn ha-1 +2.5 kg B ha-1 resulted in highest net return (` 81217 ha-1) and B: C ratio of 3.13.

Dry direct seeded rice (DSR) has emerged as an economically viable alternative to puddled transplanted rice to address emerging constraints of labor and water scarcity and the rising cost of cultivation. However, wide adoption of DSR is seriously constrained by weed management trade-off. Therefore, the availability of effective weed control options is critical for the success and wide-scale adoption of DSR. A field study was conducted at ICAR-National Rice Research Institute, Cuttack, India, in the dry seasons of 2015 and 2016 to evaluate the performance of three crop establishment methods and five weed control practices on weed management, productivity, profitability and energetics of dry DSR. The results demonstrated that weed density and weed dry weight was lower in drill seeding than broadcast seeding by 26–36% and manual line-seeding by 16–24%, respectively, at 30 and 60 days after crop emergence (DAE). Among herbicides, post-emergence application (17 DAE) of azimsulfuron was most effective in controlling weeds compared to early post application of bispyribac-sodium and bensulfuron-methyl+pretilachlor. Weed competition in the weedy check treatment resulted 58% reduction in rice yield. Among establishment methods, drill-seeding was most profitable with US $ 685 ha−1 higher net income than broadcast seeding primarily due to higher yield. Among weed control treatments, azimsulfuron was most profitable resulting in US $ 160 and 736 ha−1 higher net income than weed free and weedy check, respectively. The specific energy was lowest for drill seeding among establishment method and azimsulfuron among weed control practices, suggesting lowest energy consumed in producing per unit of grain yield.
