Abstract
Experimental results revealed that the imposition of different treatments had a significant influence on fruit maturity, yield and improving quality of the fruits. Maximum number of fruits per panicle at the time of harvesting (14.74), highest fruit retention % (68.87), maximum yield/plant (40.35 kg), least fruit cracking % (0.87), highest fruit weight (21.98g), fruit length (26.52mm), fruit diameter(25.50mm), aril weight (15.30g), juice content (10.03 ml) and lowest seed weight (3.20g), maximum TSS (18.94ºBrix), total sugar (16.25%), reducing sugar (13.23%),non-reducing sugar (3.27%) and highest anthocyanin content of the peel (24.28 mg/100g) with minimum titratable acidity (0.24%) were recorded in treatment T9 (Covering of panicle with white colour polythene). As for the storage life of litchi, T3 (Covering of panicle with brown paper) was observed to have the longest shelf life (5 days). However, non-significant effect was found in peel weight, titratable acidity and shelf life of the fruits.
Therefore, covering of litchi panicle after fruit setting with white colour polythene in addition to recommended package of practices may be recommended to the litchi growers under hot and humid regions of Arunachal Pradesh to obtain maximum yield and best quality fruits of litchi.
Description
The present investigation was conducted to evaluate the influence of panicle covering on litchi cv. Muzaffarpur. It was carried out on 10 years old trees of uniform size at the Fruit Research Farm (Litchi Block), Department of Fruit Science, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh during the year 2020-21. The experiment was laid out in Randomized Block Design (RBD) with 10 treatments and 3 replications with 2 plants per replication. The treatments were: T1 (Control), T2 (Covering of panicle with butter paper), T3 (Covering of panicle with brown paper), T4 (Covering of panicle with brown paper with polythene lining), T5 (Covering of panicle with cellophane paper), T6 (Covering of panicle with muslin cloth), T7 (Covering of panicle with insect proof net), T8 (Covering of panicle with transparent polythene), T9 (Covering of panicle with white colour polythene), T10 (Covering of panicle with blue colour polythene).
