ABSTRACT
The present investigation was conducted to ascertain the effect of pruning (10-20cm of shoot length) and bio regulators (NAA 250ppm, Urea 15%, Ethrel 500ppm and Cycocel 50ppm) on reproductive and yield parameters of guava variety Sardar. Observations revealed that pruning treatment significantly influenced both reproductive and yield parameters of trees. Significantly maximum Days taken from 50% flowering to harvesting (56.50), Duration of flowering (21.85), Number of flowers per plant (48.97), Per cent fruit set (78.10%), Number of fruits/plant (37.60), Fruit yield /plant (5.51), Fruit yield /ha (1.52) and minimum total crop duration (120.25) were noted in pruned plants. Although, the minimum days taken from 50% flowering to harvesting (51.75) and maximum duration of flowering (24.38), Number of flowers per plant (52.81), Per cent fruit set (85.50%), total crop duration (127.38), Number of fruits/plant (41.75), Fruit yield/plant (6.31), Fruit yield /plant (1.83) were found in bio regulator treatments, effect of NAA was more pronounced. All reproductive and yield parameters were significantly influenced by interaction of pruning and bio regulators except Total crop duration which showed non significant difference, In interaction Pruning with NAA 250ppm treated plants exhibited maximum Number of fruits/plant (48), Fruit yield /plant (6.88), Fruit yield /ha (1.92).
Key words: NAA, Guava, Bioregulators, Urea, Cycocel.
