- Abstract
An investigation was carried out at College of Agriculture, V.C. Farm, Mandya during summer seasons of 2021 and 2022 to study the impact of nano nitrogen and nano zinc fertilizers on sustainable paddy production under different systems of establishment. The study consisted of fourteen treatments involving different concentration and sources of nitrogen with nano nitrogen and nano zinc under different establishment methods viz., transplanted paddy and system of rice cultivation (SRI) and different methods of application of nano fertilizers like seed treatment, root dipping and foliar spray. The experiment was laid out in randomised complete block design (RCBD) and replicated thrice. The results indicated that significantly higher leaf area (636.97 cm² hill-1), DMA (330.64 g), productive tillers (27.05), filled grains per panicle (182.33), grain and straw yield (7045 and 9152 kg ha-1, respectively) at harvest, gross returns (Rs.1,43,007 ha-1), net returns (Rs. 87,052 ha-1) and B:C ratio (2.56) was obtained with the application of 75 per cent N and two foliar sprays of nano nitrogen and nano zinc at 25 to 30 and 45 to 50 DAT under SRI method of establishment.
