Abstract
The pot culture experiment was conducted to study the effect of foliar application of boron through boric acid @ 0.2, 0.4, 0.6 and 0.8 percent and soil application of borax @ 2.5 kgha-1 and 5.0 kg ha-1 on growth and yield of French bean Cv. Phule Suyash. In Entisol at Division of Soil Science and Agricultural Chemistry, College of Agriculture, Pune, during Rabi 2017-2018. The experimental soil was deficient in boron (0.35 mg kg-1). There were eight treatments replicated thrice in a completely randomized design. Application of GRDF (50:110:110 N, P2O5, K2O kg ha-1) along with two foliar sprays of boric acid @ 0.6 per cent at 25 and 55 DAS recorded significantly higher uptake of nitrogen (3.58 g pot-1), phosphorus (0.23 g pot-1), K (1.84 g pot-1) and Boron (39.91 mg pot-1). Significantly higher protein (22.65%) content in french bean was recorded with the application of GRDF along with soil application of borax @ 5 kg ha-1 at the time of sowing and it was closely followed by GRDF + Two foliar sprays of boric acid each @ 0.6 per cent at 25 and 55 DAS (22.50%).
