Nutrient dynamics in soil as affected by planting methods, water management and weed management in dry seeded rice
Author(s): Neelam Bisen and Ramesh K Singh
Abstract: Field experiments were conducted on rice (Oryza sativa L.) to evaluation of nutrient balance sheet as influenced by planting methods, water management and weed management in dry seeded rice, at irrigation plot (UGC, SAP project), Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (Uttar Pradesh) during kharif seasons of 2016 and 2017. The experiment was conducted in split plot design with four replications and 20 treatment combination. Results showed that maximum losses/ gain of nitrogen, phosphorus and potassium was maximum in FIRB planting, (-2.35 and -5.92 kg/ha), (2.02 and -0.91 kg/ha), and (-63.72 and -57.64 kg/ha) during 2016 and 2017. Among water management the net gain /loss was higher in saturation to field capacity (-3.61 and -5.96 kg/ha) N, (2.05 and -1.04 kg /ha) P and (-63.09 and-57.91 kg/ha) K during 2016 and 2017 respectively. Among the weed management treatments the weedy check recorded maximum gain in N (7.10 and 2.68 kg/ha), and P (2.88 and 0.18 kg/ha). The minimum losses of K (-54.06 and -51.88 kg/ha) was also recorded in weedy check during both year. Thus it needs to evolve such practices of planting, water and weed management in DSR, that it maintains the balance in soil with sustainable yield.
