Peanut crop yield under full and deficit irrigation in the reproductive phase

ABSTRACT Peanut cultivation has national and global significance in agriculture industry. Under water-limited conditions, its yield decreases to the extent that it compromises success of exploitation. This study focused on evaluating peanut crop production components under full deficit irrigation applied reproductive phase, determine impact water supply peanuts grown off-season State São Paulo, Brazil. The experiment was conducted for two years followed a randomized blocks design with five levels distributed strips, four repetitions. treatments consisted evapotranspiration replenishments from 100 10%. In first year, suitable temperatures, maximum reached 3,922 kg ha-1 application 277 mm depth decreased up 35% lowest (48 mm). second suboptimal temperatures caused delay growing cycle 33% reduction yields. Despite potential benefits increasing productivity, low pose risk yield, especially during region.
