The role of decomposed organic fertilizer inoculated with fungi and bacteria in enhancing wheat growth

Abstract

To reduce the addition of chemical fertilizer to agricultural soils, this research has been conducted to assess the impact of three types pre-decomposed organic manures (chicken, sheep, and alfalfa green manure) on productivity of wheat plant (Triticum aestivum L.). after composting process of selected manures, the pot experiment was conducted to study the effect of inoculated and decomposed manures at three rates (0.5%,1%,2% w/w) on wheat growth. Essential growth parameters such as number of seeds and spikes, weight and protein of seeds, length of shoot and root, Concentration of N, P and K in wheat plant under the effect of local manures were studied. The results shows that chicken manure at rate of 2% had greatest result in weight and number (25.96g ,683.33) of seeds also protein percent (16.72) compare to other treatments, while sheep manure at rate of 2% recorded high result in number of spikes parameter. Number, weight of seeds and root length gets low result (101.00cm ,3.84cm ,25.73cm) with adding 0.5% alfalfa green manure. Also, Number of spikes, seed protein and shoot length gets low result (2.93 ,12.69 ,81.40) with 0.5%sheep manure. The growth parameter of length of shoot and root reveled maximum (101.06cm, 50.06cm) with chicken manure2% and minimum (81.40cm, 25.73cm) with sheep manure0.5% and alfalfa green manure0.5% respectively. Macro nutrients of N and K gets high value (3.89%, 2.90%) in chicken treatments2% respectively and P gets high amount (0.90%) in alfalfa green manure2%. Lowest result of N, P and K (2.24%, 0.14%, 2.23%) recorded at 0.5% rate in alfalfa green manure and chicken manure respectively. The study tells that decomposed chicken manure2% generally have great effect on growth and yield of wheat plant compare to other manures and rates.
