Pattern of Fruit Drop, Yield, Maturity and Harvesting of Different Varieties of Ber (Ziziphus mauritiana Lamk.) in New Alluvial Zone of West Bengal

Abstract

during 2015-16 with fourteen cultivars of ber to understand and provide a wealth of usable information of ber breeding programme. All the varieties showed wide variation of fruit set (3.9-31.4%), fruit drop (63.085.5%) and retention (14.5-36.9%). Higher percentage of fruit set was noted in Sanur-2 (31.4%), BAU-1 Kul (26.5%), Umran (26.1%), Banarasi Karaka (24.8%). A large percentage of fruit dropped before reaching the maturity stage. However, the heaviest drop was recorded in the variety Banarasi Karaka and minimum in Umran. In all the cultivars the fruit drop was maximum up to 30 days after fruit set, declining later on. In Sanur-2 the fruit set percentage was highest but fruit retention was not up to the mark. Fruit maturity among 14 varieties was 111 to 149 days with a longer period of harvesting (21-37 days) and wide range of yield (15.96 to 46.36 kg/tree). BAU-1 Kul, Gola and Jogia were harvested earlier and Apple Kul, Banarasi Karaka Madhabpur, Mundia, Umran were harvested late. Duration of harvesting was longest in Illaichi. Umran and Topa were higher in fruit yield (46.36 kg and 43.77 kg/plant, respectively).

Advancement and efficacy of plant growth regulators in Ber (Ziziphus mauritiana Lamk) - A review

“…In ber fruit retention varies with varieties. There is a significant relationship between fruit retention and fruit set (Adhikary et al, 2019). Higher fruit setting does not lead to maximum fruit retention.…”
