Interaction effect of sulphur and phosphorus on yield and nutrient content of lentil
|

Abstract: A field experiment was conducted on sandy soil at Ismailia Agric. Res. Station, Egypt to study the effect of sulphur and phosphorus interaction on lentil (Giza 370 variety) yield, its components and nutrient contents of seeds and straw. Treatments comprised in combination with four levels of both sulphur (0, 250, 500 and 1000 kg S/fed) and phosphorus (0, 20 40 60 kg P2O5/fed).
Generally, it can be concluded that under the present study, increasing the application of S or P fertilizers significantly increased seeds and straw yield of lentil and its components up to certain levels of 500 kg S/fed and 40 kg P2O5/fed, after which additional applications reduced the yield significantly. The interaction between S and P was significantly and the highest yield was obtained by combination of 250 kg S/fed and 40 kg P23O5/fed. In contrast, appreciable reduction in lentil yield was found with further increase of s and P levels.
As for nutrient contents of seeds and straw, it was found that the combination of s and P significantly increased N and P contents of seeds and straw progressively up to certain levels. It has a higher effect than individual S or P on increasing P content. The interaction of S and P was significant, and the highest contents of N and P in seeds (4.50% and 0.84%, respectively) were obtained at 250 kg S/fed and 40 kg P2O5/fed. There was no significant effect of S and P fertilizer application on the K content in seed and straw. The total S content in seeds and straw increased significantly with every successive application of S over control. Similarly, P fertilization also helped in increasing the S content with increasing rates of p application was higher in the presence of the higher rate of S than the lower rate and control. The S and p exhibited a strong synergistic relationship for lentil nutrition.
