Abstract

A field experiment was conducted at University of Agricultural Sciences, GKVK, Bengaluru during kharif 2022 to studies on influence of lipo-chito oligosaccharides, nano and water-soluble fertilizer on growth and growth parameters of soybean [Glycine max (L.) Merrill]. The experiment was laid out in randomized complete block design with ten treatments and replicated thrice. The results revealed that application of 75% recommended dose of NP + 100 % K along with soil application of lipo-chito oligosaccharide (LCO) fortified bio-fertilizer @ 10 kg ha-1 + foliar application of 19:19:19 @ 2 % spray at flowering and pod filling stages recorded significantly higher leaf area, leaf area index at 60 DAS (1772 cm2 plant-1 and 4.91 respectively), leaf area duration (57.59 and 81.07 cm2 day-1 at 30-60 DAS and 60 DAS-harvest, respectively), no. of nodules plant at 35 DAS (31.12), total dry matter accumulation (12.74 and 20.05 g plant-1 at 60 DAS and harvest, respectively), absolute growth rate (0.24 and 0.30 g day-1 at 30-60 DAS and 60 DAS-harvest, respectively), crop growth rate (8.15 and 9.21 g cm-2 day-1 at 30-60 DAS and 60 DAS-harvest, respectively) and relative growth rate (0.031 and 0.040 g g day-1 at 30-60 DAS and 60 DAS­­-at harvest, respectively).
