Abstract:
A field experiment conducted during the third crop season of 1981—'82 in
the rice fallows of the Rice Research Station, Kayamkularn, to study the comparative
efficiency of soils as well as foliar application of nitrogen, phosphorus and their
combination on the growth, yield and quality of blackgram revealed that the grain
yield was significantly increased by the combined application of nitrogen and
phosphorus partly through soil and partly through foliage. The maximum grain
yield (1631 kg/ha) and net profit (Rs. 3254.80) were recorded by the treatment in
which both nitrogen and phosphorus (20 kg N and 30 kg P205/ha) were given 1/3
through soil as basal dose and 2/3 in two equal split doses through the foliage, at
the vegetative phase and at flowering. Protein content of grain and grain protein
yield were also significantly influenced by the treatments receiving both nitrogen
and phosphorus partly through soil and partly through foliage.
