Abstract

Foliar nutrition is aimed to eliminate the problems of fixation and immobilization of nutrients. Hence, foliar nutrition is being recognized as a significant way of fertilizing modern agriculture, especially under rainfed conditions. Nano fertilizers because of smaller size and higher surface area are efficient as compared to conventional and produce better results when used in combined form. The experiment was laid out in Randomized complete block design with three replications. A field experiment was conducted in black clayey at Agricultural Research Station, Dhadesugur, during Kharif 2023. There were eight treatment combinations, consisting of different levels of conventional and nano fertilizers. RDF - 150:75:75 kg N:P2O5:K2O ha-1 and 50 % of N, entire P and K were applied as basal and remaining 50 % of N was top dressed at tillering and panicle initiation stage. RNR- 15048 variety of transplanted rice. Application of 50 % Rec. N with soil application + 50 % Rec. N through nano urea with two applications (at tillering and panicle initiation stage) + Rec. P & K with soil application recorded significantly higher number of green leaves, leaf area and leaf area index at harvest (52.7, 954.8 cm2 plant-1 and 4.77, respectively). It also produced higher panicle length (20.1 cm), number of grains panicle-1 (242.3), panicle weight (3.73 g plant-1), test weight (19.1 g) and grain yield (5578 kg ha-1). Nutrient content and uptake also showed higher values for the same treatment. Combined application of conventional and nano fertilizers helped to increase growth, growth attributes like number of leaves, leaf area, leaf area index, yield attributes, yield, nutrient content and nutrient uptake of transplanted rice.
