Organo-Mineral Fertilization Effects on 1,000 Kernels Weight of Winter Wheat in Constan?a Area

摘要

Fertilization plays an important role in achieving superior yields, both quantitatively and qualitatively. This paper is based on investigations carried during 2017-2019 on experimental plots located in N?vodari, Constan?a County, on a chernozem, with low alkaline reaction, medium level content of total N and P and good level content of K.? The experimental plot is part of the pedoclimatic micro-zone I1O - CZ (K) - Micro zone of limestone chernozems, with coastal climate, in regions with corrugated landscape. The zone belongs to the climatic zone I1 - dry drought, seaside climate, average annual temperature 10.5 - 11.5 ° C, solar radiation 132 - 136 kcal/cm 2 , monthly average precipitation 350 - 400 mm. In the experiment, we used two wheat varieties, Glosa and Genesi, and varied fertilization variants: NPK 15:15:15, manure and foliar fertilizer, at different doses. Under these conditions, the aim of this study is to evaluate the effects of organo-mineral fertilization on wheat production, in terms of quantity and quality. In the case of wheat it was found that TKW (thousand kernels weight) can be influenced by agro-ecological conditions, agro-technical measures, mineral fertilization and irrigation. The results showed a synergistic effect of organo-mineral fertilizers on TKW
