Studies on Fertigation with Organic Manures for Tomato

Application of compost 5 t ha-1 + 2 t ha-1 lignite significantly increased the average fruit weight, fruit yield per plant, fruit yield, nutrient contents in fruit and plant, fertilizer use efficiency, net return, B: C ratio. Daily method of fertigation significantly increased the chlorophyll content at fruit set stage, average fruit weight, fruit yield per plant, fruit yield, POC, SOC, POC : SOC ratio in soil, available nutrients in soil, nutrients content in fruit, fertilizer use efficiency, net return and B : C ratio over conventional method of fertilizer application. Combination effect of methods of fertilizer application and doses of NPK fertilizers resulted in significantly higher average fruit weight, fruit yield per plant, fruit yield, available N and P in soil and N content in plant. Combined effect of organic manures and doses of NPK fertilizers significantly enhanced fruit yield of tomato. Combined effect of organic manures and methods of fertilizer application significantly increased fruit yield of tomato and available nitrogen in soil.
