ABSTRACT
This research was conducted at Universidade Federal de Campina Grande, Technology and Natural Resources’ Center, Academic Unit of Agricultural Engineering, under a protected environment, with the following geographic coordinates: latitude 07 º 13 'S, longitude 35 º 53' W and an average altitude 550 m. The objective of this work was to evaluate the production of sesame when subjected to different levels of water stress on soil and fertilizer levels, to define the best management of water and organic fertilizer in order to increase sesame’s production. The largest flower’s production of sesame’s plants occurred with increasing levels of water stress in relation to the production of plants grown without water limitation. In the variable fruit’s number the production decreased with increasing water stress. In relation to the treatment with 40% of water stress the production per plant was 13.63 g of fruits and 5.55 g of seeds, reducing the higher levels of water stress. The organic fertilization with biosolids resulted in higher altitudes of the plants.
