Abstract:
The damaging effect of climate change on global food security has assumed a frightening dimension leading to food shortages due to water scarcity especially in developing nations. The need for efficient irrigation scheduling for improving productivity especially pepper therefore, became imperative. In light of this the growth, yield and water-use pattern of chilli pepper under limited water conditions was determined in Akure, Nigeria. Experimental set-up was a randomized complete block design of four treatments and three replicates. Plot A was irrigated at full evapotranspiration (100% ET) for three days, Plot B at 75% ET for four days; Plot C at 50% ET for five days while Plot D was irrigated at 25% ET for seven days. Agronomic, soil parameters and crop’s consumptive water use were measured and results subjected to statistical analysis. Findings showed varying responses of chilli pepper to different water treatments. Average plant height values and stem diameters in plots A, B, C and D were 138.8, 132, 177.5 and 159 and 1.7, 2.0, 2.3 and 2.1 cm, respectively. Total yield values in all the treatments were 1.28, 1.45, 2.64 and 1.75 ton ha-1 in A, B, C and D, respectively. Consumptive water use of crop was maximum in all the plots at 13 Weeks After Planting (WAP), 2.85 mm in A, 3.25 mm in B, 3.58 mm in C and 3.63 mm in D. Increasing water application beyond C does not result into increased growth and yield but losses. Statistical analysis among the agronomic parameters showed significant difference (p<0.05) in all the treatments. The tremendous effect of water use pattern on the yield and agronomic parameters of the crop was evident from the study.
