Influence of farmyard manure, biological inoculation and organic extract on peanut productivity under organic farming system in sandy soil [electronic resource].

Includes reference.

A field experiment was carried out for two successive summer seasons (2007and 2008) in sandy soil at EL- Ismailia Agriculture Research Station EI-Ismailia Governorate to study the effect of farmyard manure(FYM) applied at different rates 0,10,20,30 and 40 m³ fed⁻¹ with either inoculation with a mixture of biofertilizer P (Bacillus megatherium), K (Bacillus Circulans) dissolving bacteria and N2 -fixer ( Bradyrhizobium) or non -inoculation. All plots of experiments were foliar treated with different rates (100,200 and 400 L fed⁻¹ ' ) of organic extract (rabbit manure). Results indicated that mean values of peanut yield components increased significantly due to the application of high rate of FYM ; these increases were 81.2%,and 79.7% for seeds and straw, respectively. High rates of orgcmic extract were more effective as compared to lower rate . Moreover, using mixed inoculation treatment, also, affected significantly the peanut yield (seedsand straw) as compared to non -inoculation ones.
