Abstract:
A field experiment was carried out during the kharif seasons of 2018 and 2019, at Crop Research Farm (CRF), Department of Agronomy, NAI, SHUATS, Prayajraj, U.P. In order to compare the effects of three different transplanting techniques—manual transplantation of 14-day-old seedlings, mechanized transplanting of 14-day-old seedlings, and transplanting of 21-day-old seedlings (SRI) and seven nitrogen management practices viz. RDN (100 percent N inorganic), RDN (75 percent N inorganic + 25 percent N through PM), RDN (75 percent N inorganic +25 percent N through VC), RDN (75 percent N inorganic +25 percent N through VC + Azospirillum SI), Leaf Color Chart (LCC) based N application, and Soil Test Crop Response (STCR) N application a based-on target Yield. The experiment was set up using a split plot design, with a main plot consisting of three planting techniques and seven nitrogen management techniques as sub plots that were replicated thrice. During both of the experiment's years, manual transplantation of 14-day-old seedlings (SRI) resulted in considerably greater growth parameter, yield, and yield attributes while being equivalent to other planting techniques. Comparable to the application of RDN (75 percent N inorganic +25 percent N through PM), RDN (75 percent N inorganic+25 percent N through PM+ Azospirillum SI) produced significantly higher growth and yield parameters.
