Effect of Liquid Steeped Chicken Manure and Liquid Steeped Peanut Cake Applied Through Drip Irrigation on Tomato Growth

A pot experiment with tomato cv.Hongbaoshi grown on perlite and soil receiving liquid steeped chicken manure and liquid steeped peanut cake applied through drip irrigation system was conducted to find out the feasibility of this new application method of the two manures.As compared with tomato specific nutrient solution,under perlite culture,fruit yield of liquid chicken manure and peanut cake treatments was only 64.5% and 82.9% of that of nutrient solution,respectively.Under soil culture,fruit yield of liquid chicken manure and peanut cake treatments was 147.0% and 82.8% of that of nutrient solution,respectively.No significant difference of single fruit mass,contents of total soluble solids and titratable acids of fruits was observed among treatments. The dregs was 3.5% when chicken manure was steeped and most of the liquid could be injected into drip irrigation system.However,there was much more dregs(accounting for 74.0%) when peanut cake was steeped which made it unsuitable to be used in drip irrigation system.
