Abstract:
The field experiment entitled, “Effect of foliar application of bio-stimulants on growth, yield and uptake of nutrients in rice (Oryza sativa L.)” was conducted during kharif, 2021 at Instructional Farm, Department of Agronomy, College of Agriculture, Dapoli, Ratnagiri, Maharashtra. The treatments comprise of Sea grow powder, Triacontanol, Chitosan and Chitosan irradiated. Parameters such as plant height (cm), number of functional leaves hill^-1, number of tillers hill^-1, dry matter hill^-1 (g), number of panicles hill^-1, number of grains panicle^-1 and panicle length (cm), grain yield (kg ha^-1) and straw yield (kg ha^-1) were observed with application of various bio-stimulants at 30, 60 and 90 DAT and at harvest stage. The results of the experiment showed that application of different bio-stimulants has positive effect on growth, yield attributes and yield of rice. Significantly higher values of above-mentioned parameters were recorded with application of bio-stimulant Sea grow powder @ 1.5 g lit^-1 (T₃) and lower values were observed with treatment T₇ Control (Water spray). Thus, higher growth and yield can be obtained with foliar application of bio-stimulant (Sea grow powder) @ 1.5 g lit^-1 (T₃) along with RDF in rice crop.
