Experiment was conducted with the objective to cointified the impact on flowering, fruiting, fruit development and yield parameters of Kinnow mandarin at Hisar, Haryana condition. The experiment was carried out consecutively for four year (2011 to 2014) on 16-19 years old kinnow plants planted at 6×6 m spacing in a block of one hectare. Flowering density and fruit set percentage did not vary with the seasons, whereas, more June drop and less final fruit retention, yield & fruit weight was found in the late flowering years during study period. The early flower bearing years showed less June drop, more fruit weight and yield. During stage 1st (From the month April to May) the different weather parameters played the significant role from the flowering to fruiting. The maximum (Tmax) and minimum temperature (Tmin) and evaporation showed, the significant positive correlation with the diameter, fresh and dry weight and peel thickness, whereas the morning and evening relative humidity was significantly negative correlated with peel thickness and non-significantly negative correlation with diameter, fresh and dry weight of Kinnow mandarin citrus fruit. Significant variation in stage 1 to 3 from flower bud initiation to physiological maturity of fruit was found in respective year of study. The pooled correlation coefficient in the stage 1 with the Tmax, Tmin, BSS, evaporation, and rainfall positive and RHm, RHe negative correlated with the fruit diameter, Fresh weight (g), Dry weight (g) and Peel thickness (mm), stage 2 negative correlation with Tmax and Tmin, evaporation but RHm, RHe, and rain negatively correlated with peel thickness and positive correlated to RHm, RHe, and rainfall, stage 3 negative correlated.

Key words: Orchard Kinnow fruiting, flowering, weather impact, correlation, optimum weather parameters
