| Abstract | ||
| Two field experiments in randomized complete block design with three replicates were carried out at Shandweel Agriculture Research Station, during 2013 and 2014 seasons. The objective of the the present study is to evaluate the application of organic fertilizer (FYM), biofertilizers (Microbien), humic acid and fulvic acid as substitutions of all or part of the nitrogen chemical fertilizer in fertilizing common bean variety Paulista. The obtained results indicated that any treatemnt of adding FYM, microbien and humic and fulvic acids with the recommended dose of nitrogen increased values of plant height, fresh root weight at 50 and 70 days from planting, nitrogen content fresh pods (%), leaf area and number of pods/pant more than vaules the N rocommended dose (RD) only, and then with ¾ N RD and ½ N RD, especially with adding humic and fulvic acids. Adding FYM, microbien and humic and fulvic acids with the recommended dose of nitrogen increased pod length, fresh pod yield (ton/fed) and exportable fresh pods yield (ton/fed) more than the N values rocommended dose (RD), and then with ¾ N RD and ½ N RD, especially with adding FYM. Adding FYM was effective on nitrogen content in leaves (%) at the high levels of nitrogen (rocommended dose (RD) and ¾ N RD), while, the effect of adding humic and fulvic acids were realized at the level of ½ recommended dose of nitrogen fertilizer. The highest fresh pods yield, i.e., (3.985 and 3.961 ton/fed) were recorded by the combination between the recommended dose of chemical nitrogen plus the farm yard manure in the first and second season, respectively. No significant effect between ¾ RD (N) + FYM, ¾ RD (N) + Microbien and ¾ RD (N) + humic and fulvic acids compared with the recommended dose of chemical nitrogen of the most studied traits. It is clear that the application of organic and biofertilizer with ¾ chemical fertilizer not only improve crop productivity but also decrease of mineral frtilizer and reduce environmental hazards. | ||
