Abstract
The present research entitled “Effect of crop load and foliar sprays of nutrients on yield and quality of pomegranate (Punicagranatum L.) cv. Bhagwa.” was carried out during September, 2018 to February, 2019 at Gurrampode village of Nalgonda District, Telangana. The experiment was laid in factorial completely randomized block design with three replications.
The experiment was executed with objectives tostudy the effect of crop load on yield and quality of pomegranate cv. Bhagwa, to study the effect of foliar sprays of nutrients on yield and quality of pomegranate cv. Bhagwaand study the interaction effect of crop load and foliar sprays of nutrients on yield and quality of pomegranate cv. Bhagwa.
Among the treatments of crop load (30, 40, 50 fruits per tree and no fruit thinning) in hasta bahar crop of pomegranate, 30 fruit per tree recorded maximum fruit weight (250.78g), fruit diameter (7.69cm), fruit firmness (5.52kgcm-2), fruit volume (246.65ml) and weight of 100 aril (31.22g).Significantly high yield per tree (9.91kg) and yield per hectare (8.13 t) were noticed in 50 fruits per tree. In quality parameters, crop load was significantly affected the total soluble solids, titrable acidity, total sugars and reducing sugars. Among the treatments in crop load 30 fruits per tree recorded maximum total soluble solida (15.78 oBrix), reducing sugars (8.98%), non-reducing sugars (9.33%), anthocyanin (30.07%) and total sugars (18.30%)
showed significant results. Ascorbic acid and shelf life are not significantly affected by treatments of crop load during experiment.
Among different level of nutrient, CaCl2 (1%) + H3BO3 (0.2%) + ZnSO4 (0.2%), CaCl2 (3%) + H3BO3 (0.4%) + ZnSO4 (0.4%), CaCl2 (5%) + H3BO3 (0.6%) + ZnSO4 (0.6%) and control in hasta bahar crop of pomegranate, CaCl2 (5%) + H3BO3 (0.6%) + ZnSO4 (0.6%) recorded maximum fruit weight (218.77g), fruit diameter (6.98cm), fruit volume (212.10ml), weight of 100 aril (27.88g), yield per tree (9.40kg), yield per hectare (7.83 t) followed by CaCl2 (3%) + H3BO3 (0.4%) + ZnSO4 (0.4%). In quality parameters, CaCl2 (3%) + H3BO3 (0.4%) + ZnSO4 (0.4%) was recorded highest total soluble solids (15.91oBrix), total sugar (18.27%), reducing sugars (8.94%) and non- reducing (9.19%).
The interaction between crop load and foliar sprays of nutrients has shown significant results, maximum fruit weight (261.12 g), fruit diameter (7.81 cm), fruit firmness (5.67kgcm-2), weight of 100 aril (32.62 g) was recorded in 30 fruits per tree in combination with CaCl2 (5%) + H3BO3 (0.6%) + ZnSO4 (0.6%). In quality parameters, maximum total soluble solids (16.36 oBrix), total sugars (20.06 %), reducing sugars (9.68%) and non-reducing sugar (10.38 %) was noticed in 30 fruits per tree in combination with CaCl2 (3%) + H3BO3 (0.4%) + ZnSO4 (0.4%).
From the results, it can be concluded that crop load (i.e. retaining of 30, 40 and 50 fruits per tree) and nutrients sprays significantly improved the fruit growth parameters i.e. fruit weight, fruit diameter and fruit volume without impairing fruit quality parameters in hasta bahar crop. Retaining of 50 fruits per tree in combination with CaCl2(5%) + H3BO3(0.6%) +ZnSO4(0.6%) recorded significantly high yield and benefit cost ratio followed by 50 fruits per tree in combination with CaCl2(3%) + H3BO3(0.4%) +ZnSO4(0.4%). In no fruit thinning, fruit diameter, fruit volume and weight of the fruits were significantly lesser than the 50 and 40 fruits per tree. Hence, the control fruits could not fetch better marketable price when compared to 50 and 40 fruits per tree.
Finally to conclude 50 fruits per tree in combination with CaCl2(5%) + H3BO3(0.6%) +ZnSO4(0.6%)followed by 50 fruits per tree in combination with CaCl2(3%) + H3BO3(0.4%) +ZnSO4(0.4%)can be recommended for hasta bahar crop in Telangana state.
