Effect of boron, gypsum on yield and yield attributes of Indian mustard (Brassica juncea L.) in amended alkali soil

Abstract

A field experiment for two consecutive seasons (2016-2017, 2017-2018) was conducted to study the effect of three levels of Boron (0.5, 1.0, 1.5 kgha–1) and three levels of gypsum (100, 150, 200 kg ha–1) on yield of mustard, nutrient uptake and changes in soil characteristics under amended alkali soil condition. Results showed that yield and yield attributes of mustard were significantly improved with application of gypsum and B, either applied separately or conjointly. Conjoint use of Boron (@ 1kgha–1), gypsum (@150 kgha–1), however, gave best performance in terms of yield, yield attributes as also the nutrient uptake and oil content of mustard. Similar observations were recorded on changes in soil characteristics particularly in respect to drop in exchangeable Na levels.
