This may secure higher photosynthetic activity in effective leaves and supplied to developing
pods with current photosynthates for proper filling, resulting in higher yield. Vekaria et al.
(2013) and Kumar et al. (2017) also found similar results.
The foliar application of 1% KNO3 at 25-30 DAS and 60-65 DAS (T7) recorded significantly
maximum gross monetary returns (Rs. 80079 ha -1 ) and net monetary returns (Rs. 48242 ha -1 )
and was at par with application of 2% KNO 3 at 25-30 DAS and 60-65 DAS (T 8) which recorded
gross monetary returns of Rs.77115 ha -1 and net monetary returns of Rs.43514 ha -1 . The
minimum gross monetary return (Rs.59856 ha -1 ) and net monetary returns (Rs. 31783 ha -1 ) was
observed in T1 (control). This might be due to improvement in growth and yield attributes and
ultimate increase in seed yield which could be the reason for enhanced economic returns in the
above treatments. Maximum B:C ratio of 2.52 was recorded with application of 1% KNO 3 at
25-30 and 60-65 DAS (T7) followed by treatment of 1 % KNO3 at 60-65 DAS (T5). The lowest
B:C ratio of 2.13 was observed in T 1 (control). Similar observation was recorded by Kumar
and Srivastava (2015).
Conclusion
Foliar application of 1% KNO 3 at 25-30 and 60-65 DAS on soybean was beneficial for getting
the higher productivity, maximum monetary returns and higher B:C ratio.
