The Common bean (Phaselous vulgaris L.) Response to Different Levels of Organic and Inorganic Fertilizers

Abstract

The high cost and excess use of inorganic fertilizers are the important concerns for high and beneficial yield of common beans and at the same time the integrated crop management practices are the universal demands for agriculture and environment. Therefore, the research was carried out from June to Sept of 2018 in the botanical garden of Agriculture Faculty, Kabul University, Afghanistan to evaluate the influence of isolate and combine application of diammonium phosphate (DAP) and PM (PM) with different concentrations on the growth, yield and yield attributes of common bean. According to the results achieved, it was found that combination of 80 kg DAP ha-1 + 5ton PM ha-1 improved the performance of common bean, with respect to 2272.33 kg grain yield( GY) ha-1 over the isolate used of DAP and PM (10 ton PM ha-1, 130 kg DAP ha-1 and control, respectively). In addition, the application of 5 ton PM + 80 kg DAP ha-1 showed positive effects on growth and yield attributes while no significant effects were observed on control (without any fertilizer application) for any trait of common bean. There were also strong positive correlations within the growth and yield attributes which indicate the importance for common bean GY. The present research showed that integrated application of DAP + PM is a good source of P and other primary elements for the growth and yield performance of common beans.
