2.7 Data collection and analysis
ET deficit
Phenology and growth parameters: Plant phenological parameters such as days to 50% flowering and 50% maturity were recorded on a plot basis from the two central rows. Plant height, number of primary branches per plant, number of leaves per plant, number of flowers per plant, stem diameter, number of pods per plant, pod length, diameter of the fruit and fruits weight per plant were recorded on plants basis by selecting five plants randomly from each plot. At maturity, whole plants from the two central rows of the net plot area (1.3 m x 2.4 m = 3.12 mThe yield response factor (Ky) of pepper which relates relative yield decrease to relative ET deficit was estimated using Equation.Where, The collected data was subjected to analysis of variances (ANOVA) using GenStat 15
