Abstract | ||||
A field experiment was conducted on a sandy soil at Ismailia Agric. Res. Station, Egypt during the winter season of 2005/2006 to study the effect of phosphorus, sulphur and zinc and their interaction on seed and straw yields of chickpea (Giza 3 var) and its nutrient contents. Treatments comprised a combination of three doses of phosphorus (0, 20 and 40 kg P2O5/fed), sulphur (0, 200 and 400 kg S/fed) and zinc (0, 150 and 300 g Zn/fed). Data obtained indicated that the individual applications of P, S and Zn fertilizers under the conditions of the present investigation had an effective role on seed and straw yields of chickpea, with a superior effect for P as compared with S and Zn. The combined applications of (PxS), (PxZn) and (SxZn) resulted in significantly higher for seed and straw yields of chickpea as compared to the individual ones. At the same time, the application of P in combination with S and Zn showed a more pronounced effect in increasing crop yield when compared with the control treatment. The highest seed yield was obtained by the combined treatment of (40 kg P2O5/fed + 400 kg S/fed + 300 g Zn/fed). In addition, increasing the levels of P, S and Zn significantly increased the N, P and S contents in seeds and straw. The Zn contents of seeds and straw decreased with the application of P, while they were significantly increased with the application of S and Zn. The combined treatments of P, S and Zn showed synergistic relationships and the combined treatment (40 kg P2O5/fed, 400 kg S/fed and 300 g Zn/fed) proved to be the most appropriate one among the studied applications. | ||||
