Abstract:
To study the retaliation performances of Phosphorous and Boron on growth, yield and yield attributes of cowpea (Vigna unguiculate Walp.) crop. A field experiment was executed during Zaid season of 2021 at crop research farm of SHUATS, Prayagraj to study about the effect of phosphorous and boron on growth and yield of cowpea. The experiment was laid out in most commonly encountered Randomized Block Design (RBD) with three replications of each treatment for all traits. In view of this experiment three phosphorous levels P1 (40 kg/ha), P2 (50 kg/ha), P3 (60 kg/ha) as well as three boron levels B1 (1 kg/ha), B2 (1.5 kg/ha), B3 (2 kg/ha). Result were revealed that maximum Plant height (75.64 cm), number of branches per plant (9.66), number of nodules per plant (16.80), Dry weight (67.24 g/plant), Seed yield (1.26 t/ha) and Straw yield (1.42 t/ha) and Harvest index (47.96 %) were found to be significantly higher with application of Phosphorous 60 kg/ha + Boron 2 kg/ha as compared to the other treatments. This study concluded that the maximum seed yield (1.26 t/ha) were obtained with application of Phosphorus 60 kg/ha + Boron 2.0 kg/ha which was significantly superior over rest of the treatments.
