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

Abstract

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 Năvodari, Constanța 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

, 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
