Economic feasibility and correlation coefficient of forage cowpea - A Review

Abstract

The present investigation was carried out to determine the economic feasibility and correlation coefficient between growth and yield contributing characters with the forage yield of cowpea. Results revealed that Interaction of variety and levels of phosphorus enabled the crop to increase seed and fodder yields significantly. Variety UPC-626 when fertilized with 80 kg P2O5 ha-1 recorded maximum green (322 q ha-1) and dry fodder yields (50 q ha-1) as compared to other varieties. With respect to economics of the treatments, variety UPC-626 gave maximum net profit of Rs. 15248 ha-1 with a B:C ratio of 1.85. Application of phosphorus at 80 kg ha-1 was found to be beneficial for getting higher profit (Rs. 12772). Variety UPC 626 gave highest net returns of Rs. 16548 and B:C ratio of 1.43 when fertilized with 80 kg P2O5 ha-1Estimates of correlation coefficient indicated positive significant relationships, existed between growth attributes (viz., plant height, no. of leaves, branches and DMA g plant-1) and green forage yield of cowpea.
