Response of peanut to sulphur and phosphorus fertilization under different moisture regimes
Abstract: A field experiment was conducted on a sandy soil at Elismailia Agric. Res. Station, Egypt to study the effect of sulphur and phosphorus rates under different moisture regimes on crop yield, yield attributes and seed oil quality of p[eanut (Gioza 5 var.). The treatments comprised three moisture regimes (25%, 50% and 75% of available soil moisture depletion) as main plots, in combination with 4 rates of sulphur (0, 250, 500 and 750 kg/fed.) and 2 ones of phosphorus (40 and 60 kg P2O5/fed.) as sub plot, were tested in a split plot design with three replications.
Generally, it could be conducted from the present investigation, as the sulphur rates increased, there was a significant increase in peanut yield and its components, when phosphorus was limited to 40 kg/fed., and for all studied moisture regimes. However, peanut yields of pod and haulm decreased significantly when sulphur and phosphorus were applied at rates of 500 kg S/fed. or more and 60 kg P2O5/fed., respectively. The highest pod and haulm yields were obtained from 500 kg S/fed., 40 kg P2O5/fed., and 25% available soil moisture depletion. As for seed quality of peanut, it was also found that oil and protein contents of peanut seeds were increased significantly with increasing the doses of elemental sulphur up to 500 kg/fed. under level of 25% available soil moisture depletion. Whereas, no appreciable change in the seed oil and protein content with the successive application of phosphorus up to 60 kg/fed.
