Abstract:

Shortage of freshwater resources and limited fertilizer usage due to cost related issues in agriculture are the basic limiting factors in food production. This study evaluated the effect of greywater application on shoot dry mater and uptake of maize crop. The experiment included five treatments canal water, untreated greywater and treated greywater through reed bed technology using Cyperus iria, Phragmites karka and Typha elephantina, arranged in a randomized complete block design. All the treatments received a basal doze of NPK fertilizer. The soil used in the experiment was silty clay in texture with 55% clay, pH - 7.70, EC - 1.07 dS m-1, CaCO3 - 12.50% organic matter - 0.17%, NO3-N - 4.60 mg kg-1, NH4-N - 1.68 mg kg-1, ammonium bicarbonate diethylene triamine penta acetic acid (AB-DTPA) extractable P and K as 0.18 and 270 mg kg-1, respectively. The treated greywater had a highly significant effect on shoot dry matter and N, P and K uptake in maize. The highest contents were found in treatments applied with greywater, treated under reed bed technology using Cyperus iria and the lowest in canal water applied treatments. Part of applied fertilizer was supplemented through greywater application.
