UTILITY OF SEWAGE WATER AS A SOURCE OF IRRIGATION WATER FOR SPINACH (SPINACEA OLEARACEA L.) AND ITS EFFECT ON SOIL HEALTH*Abhishek James, Rambharose and Nasratullah Ghulami
A pot experiment was carried out to Study the effect of sewage water irrigation on soil properties and growth and yield of spinach. The treatments comprised sewage water 0, 25, 50, 75 and 100 % together with tap water. The results indicate that 100 % sewage water gave significant positive effect on number of leaves plant-1 (10.89), fresh weight plant-1 (14.89 g) and dry weight plant-1 (1.97g). The soil fertility has increased significantly by 100 % sewage water due to high contents of organic carbon, available nitrogen (254.25 Kgha-1), phosphorus (15.06 Kgha-1) and potassium (325.27 Kgha-1) but, pH decreased slightly and higher EC (dSm-1) was recorded. The other treatment has low significance.
