Abstract:
The present research entitled “Effect of different levels of pruning and plant nutrients on vegetative growth and yield of Apple Ber (Zizyphus mauritiana)” was carried out during May, 2019 to January, 2020 at Horticulture Research Station (HRS), Konda Mallepally, Nalgonda District, Telangana. The experiment was laid in factorial randomized block design with 21 treatments 3 replications. Among the treatments of pruning (20, 30 cm and un pruned trees) in apple ber trees. The maximum shoot length (76.07 cm) was recorded with the 30 cm pruning. The maximum number of shoots per branch (26.64) were noticed in 20 cm pruning. Among the treatments of pruning, the maximum fruit weight (95.42 g), fruit diameter (4.60 cm), fruit firmness (11.84 kg cm^-2), fruit volume (22.83 ml) and fruit length, (5.49 cm), yield per tree (128.71 kg) and yield per hectare (53.98 t) were noticed in 30 cm pruning. Among different level of nutrients, Potassium Nitrate (1.0%), Potassium Nitrate (1.5%), Urea (0.5%), Urea (1.0%), Calcium Chloride (0.25%), Calcium Chloride (0.50%) and control in apple ber crop, the maximum shoot length (76.07 cm), number of shoots for branch (26.64) were noticed with the Urea 1.0%. The maximum fruit weight (97.60 g), fruit diameter (4.66cm), fruit firmness (12.07kg cm^-2), fruit volume (23.44ml) and fruit length, (5.93cm), specific gravity (4.62(g cm^-3), yield per tree (28.55 kg) and yield per hectare (5.83 t) were noticed with the 1.5% Potassium Nitrate. The interaction between pruning and foliar sprays of nutrients has shown significant results, maximum shoot length (90.50 cm), number of shoots for branch (29.83) was recorded in 30 cm pruning in combination with urea (1%). fruit weight (110.46 g), fruit diameter (5.26 cm), fruit firmness (12.50 kg cm^-2), fruit length (7.00 cm), fruit volume (24.50ml), specific gravity (5.26 g cm^-3), yield per tree (38.66 kg) and yield per hectare (8.0 t) was recorded in 30 cm pruning in combination with Potassium Nitrate (1.5%).
