Agronomic advancement in nutrients management for sustaining growth and crop contribution in wheat (Triticum Aestivum L.) [electronic resource]

Challenges of the coming few years lies in the debate that agriculture can provide the world population with food in need,
which are annually exceed. Unprecedented pressure placing on agriculture researchers to achieve food security. Field experiments
in Randomized complete block design with four replications were conducted at Agriculture Research Station, Collage of Food and Agriculture Sciences,
King Saud University, to evaluate fertilizers management in winter wheat. Treatments included nine combinations of decaying agriculture wastes
produced from different organic manures as activators and NPK fertilizers, the treatments were dual replicated two times, one with seed inoculation
with nitrogen fixer bacteria (Azotobacter) and phosphate dissolving bacteria (PDB) (Pseudomonas sp.) and without seed inoculation. Results obvious,
poultry litter manure compost followed by camel and sheep exceeded cow manure in most of the studied characters. Moreover, mixing the three types
of composts (5 and 10ton ha-1) with the half dose of chemical fertilizers could compensate the reduce dose, even the reduction equals the half dose
and recorded supervision effect in growth contribution, photosynthetic productivity, accumulation, grain yield, yield component parameters
and protein percentage. However, insignificant differences were detected due to further increase the doses of the three types of compost.
Seed inoculation with biofertilizers enhanced plants to better growth and yield performances. Lastly, it could be concluded that, recycling
of agriculture wastes to compost and using it in combination with NPK fertilizers is acceptable option and an effective practice could produce
greater yield production with better quality traits and maintain satisfactory high profit.
