RESEARCH ON THE INFLUENCE OF SOIL WORKS ON COWPEA CULTIVATED UNDER ECOPEDOLOGICAL CONDITIONS IN SOUTHERN OLTENIA

The results obtained in the cowpea culture, studied during 2016-2018 in the conditions of the sandy soils, highlight the importance of germination bed preparation and the size of the nutrition space on the growth and fructification processes of the plant. Â Analyzing the soil moisture dynamics during the plant vegetation, there is a better conservation of water in the soil, when was performed by plowing at a depth of 22-25 cm + disking to a depth of 10-15 cm,the soil moisture being within the limits of 6.98-16.8%. The best results were recorded by sowing 25 germinable seeds / m2 in a germination bed prepared by the plowing at a depth of 22-25 cm + disking of 10-15 cm deep (9.75 pods / plant, 8.85 grains / pod, 2483.5 kg / ha). This version was recorded the lowest level of weed (scoring on the EWRS scale with note 2.0, in the branching phase and 1.66, in the flowering phas
