Effect of Biochar, Compost, Chicken Manure and Mineral Fertilization on Total Uptake of NPK of Wheat and Barley in Sandy Soil

Abstract

Wheat and barley are the most important agricultural crops in many countries around the world, just behind rice and maize in importance. Hence, two field experiments with design of spit plot were carried out in winter season of 2014-2015 at the Faculty of Agriculture Research Farm, Mansoura University, Egypt to investigate total uptake of N, P and K by wheat (Sakha 68) and barley (Gemeza123) under different application rates of mineral and organic fertilizers, as well as grain Protein yield of Kg fed-1. Treatments of organic were chicken manure, compost and biochar, while the studied mineral fertilizer treatments took with rates of 50,75,100 and 125 % .The results revealed that total removed (uptake) of NPK by wheat plant were 80.88, 15.79, and 123.54, respectively; while with barley plant they amounted by 61.60, 11.21, and 56.83 were assigned with the treatment of chicken manure + 125% of recommended NPK treatments. Also, the best interaction was found between chicken manure + 125% mineral treatments which gave the highest value of protein uptake which were 310.60 and 278.76 kg fed-1 compared with other interactions of wheat and barley crops. It can conclude that Chicken manure + 125% mineral treatments were the superior in most amendments and gave the highest values of total NPK uptake and protein yield which in turn lead to improve crop productivity as well as sustain soil health and fertility.

Efficiency of Wheat Straw Biochar in Combination with Compost and Biogas Slurry for Enhancing Nutritional Status and Productivity of Soil and Plant

“…However, some limitations are associated with organic amendments application in the soil such as low yield, as compared to chemical fertilizers [24]. These amendments provide short term benefits to crop and get decomposed in one cropping season due to high temperature [25].…”

Technological, agronomical and economic efficiency of new organic and organo-mineral soil amendments

“…Integrated use of organic materials and chemical fertilizers is beneficial in increasing available nutrients content and organic carbon content in soil [12,13]. Scientifically based application of organo-mineral amendments stimulates biological activity, improves soil structure, water retention and preserves soil fertility.…”
