In order to investigate the effect of planting date and foliar application of nutrients on crop growth and seed yield of soybean variety DSb 21. A field experiment was conducted by adopting split plot design with three replications at Main Agricultural Research Station, UAS, Dharwad during kharif, 2016 and 2017. The experiment consisted of three planting dates with fortnight interval (first fortnight of June, second fortnight of June and first fortnight of July) and foliar spray of eight treatments. Among the dates of sowing, first fortnight of June (D1) recorded significantly highest values for plant height (65.54 cm), number of branches (12.42), leaf area (56.28 cm2), leaf area index (4.84), chlorophyll content (42.51) and seed yield per hectare (32.35 q). Foliar spray of KNO3 @ 0.5% + KH2PO4 @ 0.5% + Boron 0.50% (T8) recorded highest plant height (64.28 cm), number of branches (10.22), leaf area (54.47 cm2), leaf area index (4.57), chlorophyll content (43.34) and seed yield per hectare (31.41 q). In general, the results of this study indicated that planting date of first fortnight of June sprayed with KNO3 @ 0.5% + KH2PO4 @ 0.5% + Boron 0.50% were suitable for soybean planting in Dharwad region of Karnataka.
