Abstract:
A field experiment was conducted in two consecutive years (2019-20 and 2020-2021) at College of Agriculture, JNKVV, Jabalpur for assessing the yield and yield attributes of rice under different crop establishment methods and nutrient management practices. Experiment was laid out in split plot design replicated thrice. The treatments consisted of three crop establishment methods (Transplanting, SRI and Wet seeded rice) in main plot and six nutrient management practices (F1:100% NPK, F2:50% RDN + 50% N through sunhemp+100% P+100%K, F3:75% RDN + 25% N through sunhemp+ 100%P+100%K, F4: 50% RDN + 50% N through vermicompost + 100%P+100%K, F5:75% RDN + 25% N through vermicompost + 100%P+100%K and F6:100% NPK as recommended dose + two spray of PGPR (Pseudomonas) were allocated to subplot. Result of study reveal that the yield attributes, grain and straw yields were significantly higher in system of rice intensification over transplanting and wet seeded rice. The highest net returns and B:C ratio was recorded under SRI method of planting. Among the various nutrient management practices, application of 75% RDN+ 25% N through vermicompost, significantly enhanced the yield attributes viz., effective tillers m2 (350.19), panicle length (24.81 cm), weight of panicle (4.33 g) and grains/panicle (117), respectively as compared with 75% RDN+ 25% N through green manuring. Moreover, grain and straw yields were significantly higher under the treatment in which 75% RDN+ 25% N through vermicompost was applied followed by 75% RDN+ 25% N through green manuring. The net returns and B:C ratio was maximum with the application of 75% RDN + 25% N through VC being at par with application of 75% RDN + 25% N through green manuring.
