Çarşamba Ovası Koşullarında Yem ve Yeşil Gübre Amacıyla Yetiştirilen Yem Baklası (Vicia faba L.)’nın Toprağın Bazı Fiziksel ve Kimyasal Özelliklerine Etkileri

Abstract

The research was carried out in Çar?amba Plain conditions between 2000-2004. “Green manure-maize-wheat” rotation system was applied in the research that was established as to randomised block design in with four replications. Faba bean was used as green manure plant. In the research, two different application methods of green manure that were done by means of having both all parts and only root+stubble part of the green manure plant buried, different nitrogen doses application to the main crops that were grown subsequent to green manure in each two applications (0, 60, 120, 180 kg N ha-1 for maize, 0, 50, 100, 150 kg N ha-1 for wheat), chemical fertilizer application in traditional system and control subject applications in which green manure and nitrogen didn't take place, were discussed. There were no significant effects of green manure applications on the structure stability index values, aggregate stability index values, volum weights and the macro, micro pore volumes of soils. However, in the first year of rotation, structure stability index values and macro pore volumes showed based on the control as statistically significant difference. In general, both types of applications of green manure provided an increase in organic matter and total nitrogen contents of soils with respect of the control. According to research, practice and procedures in a positive effect on physical and chemical properties of soils, but the conditions of the region due to the effect of organic material that degradation quickly determined that a temporary and limited.
