| Abstract |
Modern agriculture is depended on the integration between biofertilizers and both of organic and/or inorganic fertilizers to enhance the utility of nutrients in farming system and to be safe and friend of environment. The common bio-inoculums are Effective Microorganisms (EM) and N-fixers. EM is based on four principal types of organisms commonly found in all ecosystems (Lactic acid bacteria, yeast Actinomyces, photosynthetic bacteria and Ray fungi). Meanwhile N-fixers contains dual inoculation of Rhizobium and Azospirillum.
A field experiment was carried out at Experimental Farm of Ismailia during summer season 2002 on peanut crop. In this experiment two sources of organic fertilizer; fermented compost (Comp) and town waste (T.W) with two levels of nitrogen fertilizer; full recommended (RRn) and half recommended rate (1/2RRn).
The results showed significant effects with using bio and compost fertilizers, where seed yield recorded 1086.7, 1080.5, 1022.6, 1018.3, 978.5 and 913.3 kg/fed for treatments Comp., EM, N-fixers, RRn, T.W and 1/2RRn respectively. Also, nitrogen uptake of peanut seeds was 43.76, 40, 36, 40.15, 39.95, 33.23 and 30.65 kg/fed with the treatments Comp., N-fixers, EM, RRn, Wt and 1/2RRn respectively.
Concerning the dual effect of (Bio-chemical), (bio-organic) and (chemical-organic) fertilizers, the results of the integration between EM or N-fixers inoculums and compost or full recommended nitrogen (RRn) gave higher seed yield and NPK content of seeds.
The best peanut seed yield obtained from the interaction treatment of EM+Comp.+1/2RRn followed by the treatment of N-fixers + Comp. +1/2RRn (1450 and 1235kg/fed). Nitrogen uptake in both treatments were 67.51 and 58.68 kg/fed respectively.
The treatments of town waste fertilizer revealed lower values of seeds yield and NPK uptake. The yield decreased to 1214 and 1000 kg/fed for the treatments (EM + T.W + 1/2 RRn) and (N-fixers + T.W + 1/2 RRn) respectively.
EM and N-fixers inoculums decreased the recommended rate of mineral nitrogen in the experiment to about 50%.
