Individual and interaction effects of plant growth regulators and fertigation on quality of pomegranate were investigated. Maximum mean polar diameter (9.59 cm), equatorial diameter (8.10 cm), fruit weight (206.06 g),fruit volume (190.86 cc), number of arils per fruit (416.81), aril weight per fruit (146.35 g), weight of 100 arils (35.86 g) and aril per cent (70.92 %) along with minimum specific gravity (1.090), rind thickness (5.15 mm), rind per cent (29.09%) and fruit cracking (5.58%) were recorded in F2 (100 per cent RDF through fertigation). Similarly, spray of 100 ppm NAA (N2) and 250 ppm ethrel (E2) significantly influenced the above characteristics of fruit. Treatment combination of 100 ppm NAA + 150 ppm ethrel + 100% RDF through fertigation (N2E1F2) gave better quality fruit over other treatments including control. Bangladesh J.

The experiment was conducted to observe the effect of plant growth regulators (GA3 and NAA) and micro-nutrients (ZnSO4 and Borax) on vegetative growth, flowering and yield attributes of litchi (Litchi chinensis Sonn.). ZnSO4 applied @ 0.4% resulted in maximum per cent increase in plant height and canopy spread, i.e. 5.78% and 6.65% respectively. Whereas, application of Borax @ 0.4% exhibited maximum per cent increase in plant girth (8.72%). NAA @ 2.5 ppm was effective in improving the flowering parameters of litchi. With respect to physical parameters of fruit and yield component, application of borax @ 0.4% resulted in maximum fruit set (43.76%), number of fruits per tree (1128.67), fruit yield (25.11 kg/tree), fruit weight (22.24 g), aril weight (15.65 g) and minimum fruit cracking (5.08%). Lowest fruit drop percentage (60.91%) was however caused by application of ZnSO4 @ 0.4%.

A field experiment was conducted to study the effect of foliar application of nutrients on growth, yield and fruit quality of pomegranate (Punica granatum L.) cv. Bhagwa in the experimental farm of the Horticultural Research and Training Station and Krishi Vigyan Kendra Kandaghat, Solan, Dr YS Parmar University of Horticulture and Forestry Nauni, Solan, Himachal Pradesh (India), during the year 2016 - 2017. The experiment was laid out in Randomized Block Design (RBD) with four foliar applications of potassium nitrate, KNO3 (0.5%, 1% and 1.5%); calcium chloride, CaCl2 (0.5%, 1% and 1.5%); boric acid, H3BO3 (0.2%, 0.4% and 0.6%) and their combinations. The first spray was applied one month after fruit set, and the remaining three ones were applied at one month interval. Among the various treatments, significant increase in plant height, plant spread, plant volume, fruit size, fruit weight, fruit yield, total soluble solids, total sugars, reduction in fruit drop and fruit cracking were recorded with the application of KNO3 (1%) + CaCl2 (1%) + H3BO3 (0.4%).  Leaf N, P, K, Ca and Mg were also significantly affected by the foliar application of KNO3 (1%) + CaCl2 (1%) + H3BO3 (0.4%). Therefore, the combined foliar application of KNO3 (1%), CaCl2 (1%) and H3BO3 (0.4%) was found the best treatment for the improvement of growth, yield and fruit quality of pomegranate.

Yield And Quality

The effect of different plant growth regulators on flowering, fruiting, yield, and quality of pomegranate (Punica granatum L.) cv. Bhagwa was studied in a field trial at ICAR - Indian Institute of Horticultural Research (IIHR), Bengaluru, during two seasons, namely ambe bahar (January–February) 2016 and hastha bahar (September–October) 2016-17. Nitrobenzene (NB) 1.0, 1.5, and 2.0 ml plant-1, Cycocel (CCC)  500, 1000, and 1500 ppm plant-1, Uracil  25 and 50 ppm plant-1, CCC  1000 ppm + Uracil  25 ppm plant-1, CCC  1500 ppm + Uracil  50 ppm plant-1, and Control were among the eleven treatments studied. The application of uracil  50 ppm plant-1 resulted in a higher number of hermaphrodite flowers plant-1 (264.7), number of fruits plant-1 (154.0), and fruit yield (27.1 kg/plant). Fruit weight (197.6 g), fruit length (6.64 cm), total aril weight (113.63 g), 100 aril weight (27.18 g), fruit juice weight (101.94 g), TSS content (19.96 OB), fruit anthocyanin content (6.46 mg 100 g) and low titrable acidity (0.41 percent) were recorded when CCC  1000 ppm + Uracil  25 ppm plant-1 was applied. During ambe bahar, the highest fruit width (6.90 cm) and volume (162.7 ml) were observed with CCC  1000 ppm and 1500 ppm plant-1, respectively. During hastha bahar, CCC  1500 ppm plant-1 resulted in a higher number of hermaphrodite flowers (287.8), the highest percentage of fruit set (86.10), the highest number of fruits plant-1 (156.66), the highest fruit yield (54.53 kg plant-1), the highest fruit weight (348.32 g), the longest fruit length (8.53 cm), and the largest fruit volume (8.53 cm) (33.93 ml), total aril weight (224.01 g), 100 aril weight (35.09 g), fruit juice weight (119.40 g) and TSS content (16.00 OB). A foliar spray of nitrobenzene  1.5 ml plant-1 compounded the high fruit anthocyanin content (6.47 mg 100g-1). As a result of the research, it can be concluded that CCC  1000 ppm + Uracil  25 ppm plant-1and CCC  1500 ppm plant-1were the most effective treatments for improving floral characters, fruiting, yield, and quality in pomegranate cv. Bhagwa during both seasons.
