Application of Wastewater Irrigation on Growth and Yield of Chilli Under Nitrogen and Phosphorus Fertilization

Abstract

In the present study a pot experiment was carried out in 2009 where different nitrogen (N) and phosphorus (P) combinations with soil (N0P0, N20P30, N20P60, N40P30, and N40P60) were taken into pots. Nutritional growth and yield such as length, fresh and dry weight, leaf area, leaf number, pedicle length, fruit length, fruit number, and seed content were significant at P ≤ 0.05. Evaluation of data reveals that plant growth parameters and yield of chilli significantly increased in wastewater treatment with 20 kg ha−1 N and 30 kg ha−1 P in comparison to groundwater treatments. It was also found that higher dose of fertilizers with wastewater decreases plant growth and development of Capsicum annuum L. Thus it was concluded that wastewater reuse as a source of nutrient may not only solves the problems of the more use of chemical fertilizers but also decreases the fresh water scarcity in agriculture land.
