Abstract

 
 

 A FIELD experiment was carried out for two successive summer ……seasons at Ismailia Agric. Res. Station, Ismailia Governorate, Egypt (Latitude, 30o 35' 41.901" N and longitude, 32o 16' 45.834" E) to investigate the effectiveness of soil amendments on sandy soil properties, nutritional status and peanut productivity. Two forms of organic amendments (Compost and Farmyard manure, FYM) at two rates (5 and 10 m3/fed.) and three forms of mineral amendments (Gypsum, Rock phosphate and Felds par) were applied each alone at two rates (1 and 1.5 ton/fed.).  Results indicate that values of field capacity (FC), wilting point (WP) and available water (AW) increased significantly by the application of both organic and mineral amendments as compared to control treatments at both studied seasons. Moreover, data indicate that values of soil moisture content (FC, WP and AW) increased significantly by increasing the rate of both organic and mineral amendments, however high rate was superior. Gypsum and farmyard manure treatments recorded the highest values of soil moisture content.
 
The available N, P and K in soil increased significantly in case of applying either10 m3/fed Compost and FYMor1.0 ton/fed of Gypsum, rock phosphate and Feldspar. On the other hand, the pH and EC values, decreased by applying different soil amendments. Moreover, the application of gypsum (1.0 ton/fed.) and FYM (10 m3/fed) gave the highest significant yield components as well as crude protein percentage as compared to either control or other tested treatments. The same trend was observed with (N, P and K) total content of grains, straw and apparent nutrients use efficiency for peanut.
 
Finally, application of FYM and Gypsum as soil amendments at a rate of (10 m3/fed and 1 ton/fed) respectively, improved soil chemical and physical properties and increased apparent nutrients use efficiency and yield components of peanut as well as their total content of macronutrients.
