| Abstract | ||
| The effect of organic nitrogen (compost added at 30 m3/fed., chicken manure at 20 m3/fed.) and inorganic nitrogen (calcium nitrate, ammonium sulphate added at 100, 150 and 200 kg/fed. For all them) on the production of tomato (Vr. Sacar) and some soil properties of sandy soil was evaluated through a field experiment using a complete randomized blocks design at EI-Ferdan area, EI-Ismalyia governorate. Results showed that the inorganic materials led to the best results of plant growth and yield of tomato where the calcium nitrate treatment at 200 kg/fed. gave the maximum value of plant growth parameters and fruit yield of tomato followed by ammonium sulphate, while the organic materials gave the minimum effect. The treatment of 20 m3/fed. chicken manure was more effective than 30 m3/fed. compost for the later one. On the other hand, the best results for soil properties were obtained by organic materials application, where the chicken manure treatment exhibited the highest value of organic matter, total porosity and available N, P and K, while gave the lowest values for pH, ESP and S.d. followed by compost treatment. | ||
