Farm yard manure and bio-fertilizers to replace part of mineral nitrogen fertilizer in wheat fields

الملخص EN

fertilizers to substitute part of chemical nitrogen fertilizer in fertilizing wheat crop.

The durum wheat cultivar Sohag 3 and the bread wheat cultivars Giza 168 and Sids 1 were treated with: (1) no fertilizers (control), (2) 70 kg of mineral N/faddan (recommended dose), (3) 45 kg of chemical N/fad.

+ 20 m3 FYM /fad., (4) 45 kg of mineral N/fad.

+ seed inoculation with Rhizobacterin, and (5) 45 kg of mineral N/fad.

+ seed inoculation with mixture of Rhizobacterin and Phosphorin.

The experiment was designed in split plot with four replications.

Results indicated that the differences in grain yield between cultivars were narrow, where’s Sohag 3 gave higher grain yield (18.62 ardab/fad.) and it had heavier 1000 kernel weight and higher grain protein percentage and had taller plants.

Giza 168 proved to be earlier in maturity and gave higher number of kernels/spike.

Sids 1 produced higher number of spikes/m2 and higher biological yield.

Application of 45 kg N + 20m3 FYM/fad.

resulted in significant increases in plant height, number of spikes/m2, biological yield, grain yield and grain protein percentage.

On the other hand, maturity was delayed when the application of mineral N was combining with FYM.

Also, the application of 45 kg N + seed inoculation with mixture of Rhizobacterin and Phosphorin increased number of kernels/spike and 1000 kernel weight.

Generally, results indicated that it is possible to minimize the amount of mineral N fertilizer by using FYM and/or biofertilizers.

Whereas using FYM and bio-fertilizers could prevent the environment from chemical pollution, which is harmful to human bling and animals.A field experiment was carried out during the two growing seasons 2008/09 and 2009/10 at Shandaweel Agric.
