THE INFLUENCE OF CHEMICAL FERTILISERS AND SOIL UPON THE CROP FORMATIONTO GROUNDNUTS AND THE CORRELATION WITH THE PHENOMENON OF WITHERING
AbstractDuring the years 2012-2013 it have been carried out observations and measurements on plants growth and seed filling of groundnuts under the influence of chemical fertilizers application on the sandy soils from Tamburesti Research Station. Plants accumulation of dry substance is occuring to maturity and seed weight also. Through the application of treatments with N and NP the increase is higher compared to control. Also, seed sizes and the weight of 1000 seeds are larger when N and NP fertilizer was applied compared to control. The formation of the yield is done faster and in greater quantities in the case referred to the treatment comparative with control. Seed are withered in a smaller number compared to control, when N and NP is applied. For Tamburesti variety the formation of the crop has been faster comparative with Venus variety, where the phenomenon of withering is more emphasized. The accumulation of protein and fat substances takes place until the maturity of the seeds.
