Exploitation of Plant Growth Substances for Improving the Yield and Quality of Pomegranate under Ultra High Density Planting
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 3
Abstract
The present investigation was conducted in the Department of Fruit Crops, HC & RI, TNAU, Coimbatore during the year 2011 to 2013 at Jain Irrigation Systems Pvt. Limited Farms, (JISL), Udumalpet, to investigate the response of plant growth substances on yield and quality of pomegranate cv. Mridula under ultra high density planting (UHDP). The experiments was laid out in randomized block design with nine treatment of plant growth substances viz., NAA 10 ppm, GA3 50 ppm and KNO3 1 % and combination of each two and three including of water spray and were sprayed three times from 150 days after pruning subsequently, at 30 and 60 days after first spray and absolute control were maintained. Three replications were followed to investigate various yield and quality attributes of three year old TC pomegranate (Punica granatum L.) cv. Mridula grown under UHDP. The results revealed that application of NAA 10 ppm + GA350 ppm was recorded the maximum number of fruits per plant (65.11), average fruit weight (272.5 g), Fruit volume (290 cc), fruit length (7.7 cm), fruit diameter (7.9 cm), number of aril per fruit (670), total aril weight per fruit (186.2 g), 100 aril weight (25.85 g), aril recovery (25.85 %), total seed weight (20.23 g), fruit yield / plant (17.74 kg), as compared with water spray. In regards to the quality attributes application of (GA3 50 ppm + KNO3 1 %) registered the highest values for total sugar (9.01 %), reducing sugar (7.35 %), total soluble solids (16.2 %) and anthocyanain (18.85 %) content as compared with water spray. Therefore application of three sprays of NAA 10 ppm + GA3 50 ppm starting from 150 days after pruning and subsequently at 30 days interval resulted in the highest yield attributing characters whereas, the quality of pomegranate was increased by application of GA3 50 ppm + KNO3 1 % . It could be considered as best combination for getting increased yield and quality for three years old TC pomegranate cv. Mridula.
