Punica Granatum L

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.

The study was carried out during the growing season 2013 in a private orchard in Diyala Governorate on pomegranate trees Punica granatum L. cv. Salimy which were nine old  years, all trees that chosen had uniform in size and growth were trained on three trunks and planted at 4×4m  to study the effect of three levels of potassium sulfate  (0, 1500, 3000 mg.K.L-1) and three levels of Zinc (0, 500, and 1000 mg.Z.L-1) and three levels of Gibberellic acid (GA3) (0, 20 and 40 mg.L-1) on quality and quantity of fruit yield, A factorial experiment with three replicate was carried out according to the (RCBD) using one tree on experimental unit, the experimental results showed: Potassium achieved by concentration 3000 mg.L-1 significant decrease in the fruit cracking by 18.70%, As led to increasing in yield and some of the physical qualities of fruit as fruit yield increased, fruit weight, the proportions 41.22% and 11.48% respectively, as well as with zinc as the sprayed concentration of 1000 mg.L-1  cause a decrease of 13.86% fruits cracked, and achieved a significant increase  in  fruit yield, fruit weight, As GA3 did not have a significant effect on the qualities above, the results have shown that overlap the study showed a significant  influence factors in reducing fruits drop and cracked  and improve the physical qualities of the fruit. The results showed that the proportion of total soluble solids (TSS) were not significantly affected by three study factors and increased vitamin -C- , as a result of spraying potassium concentration 3000 mg.L-1 by 20.51% , and 8.75% at 1000 mg.L-1 of zinc, GA3 achieved  increase in  vitamin -C- by 5.66%, showed the interaction a significant effects in qualities of the above with varying proportions depending on the type of factor and its concentration  added .

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.
