Abstract

Ber is an important arid fruit crop. Mature ber fruit offers rich nutrition, with abundant calcium, vitamin C, vitamin B, and vitamin A. Fruit drop poses a significant hurdle for ber cultivation in Punjab, and its status as a minor crop has led to limited research. Zinc sulphate (ZnSO4) and plant growth regulators (PGRs) effects on ber fruit drop, yield, and other physical characteristics. So, this study “The effect of PGRs and ZnSO4 on fruit drop, yield and other physical traits of ber”. In the second week of December, plants were sprayed with ZnSO4 (0.5%), Salicylic acid (SA) (300 ppm), Gibberellic acid (GA3) (30 and 40 ppm), Naphthalene acetic acid (NAA) (20 and 30 ppm), sole as well as combination and one control repeated three times. This investigation revealed that all treatments led to reduced fruit drop compared to the control. Treatment T2 NAA (40 ppm) resulted in the lowest fruit drop, whereas the control showed the highest fruit drop. Yield and yield efficiency were highest in the same treatment that is T2 (NAA 30 ppm) whereas lowest was in control. The treatment T10 GA3 + ZnSO4 + SA (40 ppm + 0.5% + 300 ppm) given the best result for Chlorophyll index, fruit weight, length, diameter, volume, and firmness whereas they were all at their lowest levels in control plants..
