Abstract

A study was carried out for 2 years in the arid zone of the northern region of the Sudan to investigate the effects of watering intervals on flowering, growth, yield and yield components of three groundnut cultivars. The variation in air temperature prevailing above the canopy through frequent and extended watering intervals affected the periodicity of flowering. MH 383 gave the highest pod yield and it was drought tolerant compared with Ashford and Turkish cultivars. Pod losses were smaller with longer watering intervals. Number of pods per plant was the yield component most affected by watering. Leaf area index increased with frequent watering and reached a value of 5·8. Net assimilation rate decreased at first, but later increased with the pegging of gynophores
