Abstract
A pot experiment was performed out at Meniat El-Nasr district, Dakahlia Governorate, Egypt to evaluate the effect of some organic residuals (rice straw and farmyard manure) on vegetative growth, yield components and chemical composition of tomato crop (Lycopersicon esculentum., Mill) grown on an alluvial soil during the successive season of 2004/2005 and residual effect of applied treatments on soil quality. Treatments were representing all combination of organic waste sources (control, rice straw (RS) and mixture of rice straw + farmyard manure (RS + FYM) were applied at the rate of 20 m3 fed-1 and N fertilizer rates (0, half and all of recommended rate as sulfate, 20.5% N) in presence of The used soils collected after cotton and the other collected after rice in split- split plot design with three replicates.The obtained results could be summarized as follows:
- The mean values of chlorophyll readings (SPAD), fresh and dry weights (g pot-1) tended to increase high significantly as a result of organic wastes and N- fertilizers applications under studied soils conditions. The highest mean values of chlorophyll readings (SPAD), fresh and dry weights at the 1st and 2nd soil respectively, occurred with the treatment of 20 m3 fed-1 of RS with FYM (W2) + half nitrogen dose (N2) (75 kg N fed-1).
- Data clearly appear that the additional of organic wastes and nitrogen had insignificant effect on N and P and K-uptake by shoot of tomato plant at two alluvial soils under studied. The highest mean values of N-uptake by shoot of tomato plant at the 1st and 2nd soil, occurred for the treatment 20 m3 fed-1 of RS with FYM (W2) + half nitrogen dose (N2) (75 kg N fed-1).
- Statistical analysis shows that means of fresh and dry yields (g pot-1) and fruits number of tomato fruit were increased highly significant due to the different additions of organic wastes and N fertilizer rates. The highest mean values of fresh weight (g pot-1) were observed at the 1st and 2nd soil respectively due to the additional of 75 kg N fed-1(half dose) with (FYM + rice straw) at a rate of 20m3fed-1.
- Data clearly appear that insignificant differences were observed with nitrogen uptake by tomato fruit due to the applications of 75 kg N fed-1 (half dose with (FYM + rice straw) at a rate of 20m3fed-1. The highest mean values of N, P and K-uptake (mg pot-1) in the 1st and 2nd soil occurred due to the addition of 75 kg N fed-1(half dose) with (FYM + rice straw) at a rate of 20m3fed-1. The highest means of P-uptake at the 1st and 2nd soil respectively, produced from the additional of W2 (RS+FYM) at a rate of 20 m3 fed-1 with N2 (75 kg N fed-1 half dose).
