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.
