Physiology and yield of piel de sapo melon (Cucumis melo L.) under water deficit in semi-arid region, Brazil
Melon (Cucumis melo L.) is a crop of great socioeconomic importance in regions with semiarid climate, as found in Northeast Brazil. In this region water deficit is a usual condition as well as the main reduction factor of plant productivity. Due to this phenomenon, irrigation techniques are used to...
