The extent of reduction in LRI with 125 and 150 per cent RDF over 100 per cent RDF, was 15.4 and 30.1 per cent, respectively at 135 DAS and 11.3 and 23.8 per cent at harvest, respectively. Whereas 3 foliar sprays of MgSO 4 +KNO 3 and MgSO 4 +19:19:19 along with soil application of MgSO 4 during flowering, boll formation and boll development stages, reduced the LRI by 18.7 and 16.2 per cent at 135 DAS and 12.7 and 11.5 per cent at harvest growth stages, respectively as compared with control (2.40 and 2.59). The leaf chlorophyll, nitrogen and magnesium contents were increased at all the stages, with higher fertilizer levels and foliar application of nutrients.
