Abstract

Two successive field experiments were conducted in a private farm at Gemiana village near El-Mansoura city, Dakahlia Government, Egypt, during seasons of 2009 and 2010 to evaluate the effect of two rates of chicken manure combined with bio-fertilizers, mineral fertilizers and some foliar application treatments as well as their interactions on vegetative growth parameters (Plant height, No. of branches/plant, No. of leaves/plant, Fresh and Dry weights)and some chemical constitutes of tomato leaves (Lycopersicon esculentum) "Nada" hybrid under drip irrigation system.
The obtained results showed that the mean values of plant height, number of leaves and branches/plant, fresh and dry weights of tomato plants, N, P, K% in the leaves, chlorophyll a, b and total chlorophyll were increased due to increasing chicken manure rate up to 6 ton/fed. + bio fertilizer mixture during both seasons of the experimentation. Also, the highest mean values of vegetative growth parameters, N, P and K percentages, chlorophyll a, b and total chlorophyll in leaves under study were obtained with increasing NPK level from 0 up to 50% of the recommended dose (RD) during both seasons.
The highest significant values of the aforementioned parameters were recorded with spraying plants by seaweed extract (2.5 ml/L.) followed by spraying yeast extract (5 g/L.). These increases were true in the two seasons of the study.
The study showed that the best results of vegetative growth parameters and N, P and K percentages in the leaves, chlorophyll a, b and total chlorophyll were recorded with adding 6 ton/fed. chicken manure + bio fertilizer mixture with 50% NPK from recommended dose and spraying seaweed extract during both seasons.
