ThesisItem Open Access Impact of girdling on flowering, fruiting and yield attributes in Litchi cv. late bedana(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-05) Agarwal, Hitesh; Satish ChandThe present investigation was carried out at Sainik Farm, Patharchatta, Pantnagar, District Udham Singh Nagar, Uttarakhand, during October, 2015 to June, 2016. The experiment was conducted to study the impact of girdling on flowering, fruiting and yield attributes in Litchi cv. Late Bedana. Twenty year old 21 litchi trees consisted of 7 treatments with two level of girdling severity of 25% primary branches and 50 % primary branches with the combination of girdling width of 2 mm, 4 mm and 6 mm, along with ungirdled control which are tested with randomized block design with three replications. The results indicated that all the litchi trees which were subjected to different severity and width of girdling have more fruit set (%), fruit retention (%), yield and good fruit quality as compared to control. However, the treatment girdling of 50% of primary branches + 4 mm wide had significantly effect on improving fruit set (38.44%), fruit retention (14.07 %), fruit yield (57.02 kg/tree) and good quality fruits (TSS- 19.290 Brix, acidity-0.61%, ascorbic acid-29.45 mg/100g pulp and TSS: acid ratio-31.45). Girdling blocks the downward flow of carbohydrate from leaves to roots thus the carbohydrate may accumulate above the girdled portion which resulted in additional supply of carbohydrates from leaves to fruits, therefore, the fruit yield and fruit quality of litchi may increase.ThesisItem Open Access Studies on Growth, Yield, Fruit Quality and Economics of Organic Management Practices in Guava (Psidium guajava L.) cv. L-49(MPUAT, Udaipur, 2021) Agarwal, Hitesh; Lakhawat, S.S.The present investigation entitled “studies on growth, yield, fruit quality and economics of organic management practices in guava (Psidium guajava L.) cv. L-49” was carried out at the Horticulture farm, Rajasthan College of Agriculture, MPUAT, Udaipur during the period of two years i.e. from June, 2018 to May, 2020. The objective of present study was to evaluate the effect of organic management practices on vegetative growth, flowering, fruiting, yield and economics of guava cv. L-49. This experiment was conducted in Randomized block design with 12 treatments and 3 replication. Results showed that among all the treatments, treatment T11 i.e. application of FYM (25 kg per plant) + Vermicompost (25 kg per plant) + Azotobactor + Azospirillum + PSB (each @ 250 g per plant) have significant effect on vegetative characters, floral and flowering characters, fruit quality parameters and yield attributing characters such as plant spread (E-W and N-S), canopy volume, number of flowers per shoot, fruit set, fruit retention, fruit diameter, fruit length, fruit weight, pulp/seed ratio, organoleptic acceptance score, TSS, acidity, TSS/acid ratio, ascorbic acid, reducing sugars, total sugar, number of fruits per tree and fruit yield etc. The maximum number of flowers per shoot (7.48), fruit set (40.43%), fruit per plant (224.67), fruit yield (50.28 t/ha), fruit weight (200.92 g), TSS (13.75 0B), ascorbic acid (195.11 mg per 100 g pulp) and net returns (Rs. 628673.08 per ha) was recorded from the treatment T11 that is FYM (25 kg per plant) + Vermicompost (25 kg per plant) + Azotobactor + Azospirillum + PSB (each @ 250 g per plant). It was also reported that soil properties and total microbial population were improved by this treatment combination.
