Abstract
The present investigation entitled “Effect of organic treatments on growth, yield and quality of guava (Psidium guajava L.)” was carried out at PG lab of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during rainy and winter season of 2020. The study material comprised of fourteen organic sources of nutrients which were evaluated for their effect on growth, yield and quality of two years old guava cv. VNR bihi in completely randomized design. It was observed that organic source of nutrients had a substantial impact on growth, yield and quality parameters of guava. It is concluded that 80% replacement of nitrogen through FYM + 20% replacement of nitrogen through poultry manure + Azotobacter + Phosphate Solubilizing Bacteria may be recommended to improve the growth, yield and quality parameters of guava. The results also showed maximum fruit length (10.08 cm), fruit breadth (12.90 cm), average fruit weight (616.30 g), number of seeds per fruit (287), TSS (12.96%), acidity (0.5%), ascorbic acid (219.05 mg/100 g pulp), diameter of seed core (56.60 mm), pulp thickness index (56.74) and pectin content (1.42%) during the winter season, whereas, the maximum number of fruits per plant (54.33) and yield (29.41 kg/plant) in the rainy season. Fruits from the winter season are preferable to those from the rainy season.
