Yield and nutrient status of wheat plants (Triticum aestivum) as affected by sludge, compost, and biofertilizers under newly reclaimed soil

Abstract

The obtained results showed that either sludge or compost as organic fertilizers increased most yield parameters, i.e., spike length, weight of spike, and number and weight of grains per spike. Grain and straw yield as well as biological yield ton/faddan increased by either sludge or compost as compared with chemical fertilizers. Nutrient uptake of wheat grain increased also by both fertilizer and dual application with either sludge or compost with biofertilizers. From the obtained results, it was revealed that application of compost or sludge with either "azotobacter" or yeast as biofertilizers has superior promoting effect on yield and yield components as well as nutrient content of the grains than chemical fertilizers. Thus, it can be recommended to substitute chemical fertilization by these organic and biofertilizers to obtain high productivity of wheat.
