Water-yield relationships of green pepper (Capsicum annuum) cultivated at different ırrigation levels
(Bursa Uludağ Üniversitesi, 2024-05-08) KUŞÇU, HAYRETTİN; Yılmaz, Sinem; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Biyosistem Mühendisliği Bölümü; 0000-0003-0150-7834; 0000-0001-9600-7685
A field experiment was carried out in Bursa ecological conditions to determine the effects of different irrigation strategies on water-yield relationships of green pepper cultivation. In the study, where the amount of water evaporated from the class A pan (E) was taken as reference, different pan-crop coefficients (kpc: 0.25, 0.50, 0.75, and 1.00) were used for four irrigation treatments (S25: E×0.25, S50: E×0.50, S75: E×0.75, and S100: E×1.00) was created. While statistically significant (p<0.05) higher yields were obtained from S100 and S75 treatments, the yield decreased significantly from S50 and S25 treatments. The decrease in irrigation levels also caused a decrease in the size and diameter of the fruit. The highest water productivity was achieved from the S75 irrigation treatment. According to the results obtained, S75 irrigation treatment can be recommended in Bursa ecological conditions to obtain higher fruit yield both per unit area and per unit volume of water. Regarding S75, seasonally applied irrigation water was found to be 368.4 mm, evapotranspiration was 516.6 mm, fruit yield was 3629 kg da-1 and water productivity was 7.02 kg m-3
