Effect of different water application on yield and water use of bell pepper under greenhouse conditions

Authors: Aladenola, O, C Madramootoo
Description: Application of proper quantity of water to crops at the right time is required for optimal yield. The effect of different water applications on yield and the stress threshold of greenhouse grown bell pepper (Capsicum annuum L.) cultivar red knight were tested. The study was conducted with four irrigation treatments 1.2 Epan (T1), 1.0 Epan (T2), 0.80 Epan (T3), and 0.40 Epan (T4) with four replicates using randomized complete block design. Highest marketable yield was obtained with 1.2 Epan. Total yield decreased from T1 to T4 irrigation treatments. Irrigation Water Use Efficiency (IWUE) and Water Use Efficiency (WUE) of 1.2 Epan and 1.0 Epan were not statistically significantly different. The crop water stress index (CWSI) values were 0.1, 0.3, 0.7 and 1.0 for T1, T2, T3 and T4 irrigation treatments respectively.
