Abstract
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.
