Effect Of Nitrogen And Phosphorus On Growth And Yield Of Okra

Nitrogen application showed significant response at all the stages of growth. An increase in the level of nitrogen up to 120 kg per hectare reflected significant increase in various growth characters of plant, yield and physico- chemical composition of fruits. But number of days taken to flowering was reduced significantly with the increased level of nitrogen. The application of 60 kg phosphorus per hectare also recorded the same trend for the characters studies as it was found in case of nitrogen. Earliest flowering and height number of fruits per plant were noted under N2P2 treatment combination where as highest yields per hectare was noted under N2P2 treatment combination, which was found significantly superior to other combination. Physico- chemical composition of fruits was also influenced by treatment combination. The length, diameter, fresh weight and dry weight of per fruit were maximum under a treatment combination of N2P2. The most important study of this experiment is the application of various nutrients 120 kg nitrogen, 60 kg phosphorus per hectare had given better results on almost all the characters under study. However, the N2P2 combination gave the highest yields.
