THE BEHAVIOR OF SOME COTTON (GOSSYPIUM HIRSUTUM) GENOTYPES UNDER SANDY SOIL CONDITIONS IN SOUTHERN OLTENIA

Abstract

This study follows the behaviour of seven genotypes of cotton (Gossypium hirsutum), cultivated on the sandy soils of Dăbuleni, with the aim of diversifying the range of plants tolerant to climatic factors in southern Oltenia. Observation of vegetative characteristics such as plant height, number of sympodia, number of flowers in the first decade of flowering and quantitative characteristics such as boll weight, fibre weight, seed weight and number of seeds / plant were the object of the study. Research on cotton plant development was correlated with climatic data recorded by the weather station of Dăbuleni RDSPCS, during the growing season from plant sowing in the field to boll formation. Following the study and showing positive results, The Beli-Lom genotype stood out in terms of flowering yield and fibre percentage, and the Cirpan-539 and Beli-Iskar genotypes had positive vegetative growth yield.
