Effect of Mineral Fertilizers on Peanut Productivity Under Drip Irrigation System

Abstract

One of important practical measures to improve soil fertility is application of organic fertilizers; in addition to providing necessary microelements for improve the productivity of crops. Two field experiments were carried out during successive seasons of 2018 and 2019 at at the National Research Center farm, Nubaria area, El-Beheira Governorate, Egypt, to study the role of fertilizers (Microelements and Hydro Follase) and drinking water purification residuals DWPR on productivity of peanut plants grown in sandy soil. A split-plot design in a randomized complete block arrangement was used with four replications. The main plots were allotted to two DWPR (10 and 20 m3) beside control, the three microelements and Hydro Follase (0% control, 50% and 100%) were devoted to sub-plots. Results showed significant of all studied parameters except shelling% for DWPR, microelements and the interactions in both seasons. The application of DWPR at dose 20 m3/fed causes an increase seed yield/plant (66.9 – 49.9 g), seed index (87.8 – 87.7 g) and seed yield/fad (1.34 – 1.33 ton) in both seasons, respectively. The results indicated that the microelements level at 100% increases seed yield/plant (72.9 – 56.8 g), seed index (90.3 – 89.3 g) and seed yield/fad (1.46 – 1.56 ton) in both seasons compared with 0 and 50%. The interaction between 20 m3/fed DWPR and 100% microelements recorded the greatest value of seed yield/fad (1.74 – 1.85 ton) in both seasons. Finally it is possible to use DWPR application at 20 m3/fedwith 100% microelements to improve the productivity of peanut under sandy soil conditions.
