Interaction effect of phosphorus-sulphur on wheat production grown on sandy soil

Arabic :

التأثير المتداخل لكل من الفوسفور والكبريت على إنتاجية محصول القمح النامى فى أرض رملية

Abstract

A field experiment was carried out on a sandy soil at the Experimental Farm of Ismaillia Station, Agricultural Research Center, Egypt to study the interaction effect of phosphorus and sulphur fertilization on the beneficial effects of farmyard manure amendment added to a sandy soil. The P rates were 0, 15 and 30 kg P/fed applied as superphosphate and S rates were 0, 50 and 100 kg S/fed applied as elemental sulphur. A comparison between mean of the control (0P+0S) with the mean of (0 P+ 50 S) and (0 P+ 100 S) treatments. This comparison showed that there was a significant positive response in both grain and straw yield to the increasing S application rate. The analysis of variance showed a highly synergetic significant P by S interaction on wheat yield and nutrient uptake. The highest three yield of either grain or straw were achieved in (30 P+ 100 S), (30 P + 50 S) and (15 P+ 100 S) treatments ranked in descending order. The differences in grain or straw yield among these three treatments were significant (P< 0.05), indicating that fertilizing wheat crop in sandy soil, amended with farmyard manure by about 50% of its total N requirement, by 30 kg P and 100 kg S/fed produced the maximum yield. Nitrogen, P, K and S uptake by wheat followed the same trend of grain and straw yields. However, no wide variations are occurred on soil chemical properties i.e. pH, EC, ESP and SSP as well as soil available N, P and K at the end of the growing season
