Abstract
A field study was carried out to study the spacing trial in high-density planting in guava cv. Hisar Safeda. There were total of seven different treatments i.e. 5 m x 3 m, 5 m x 4 m, 5 m x 5 m, 6 m x 3 m, 6 m x 4 m, 6 m x 5 m and 6 m x 6 m with four replications and the design followed was Randomized Block Design (RBD). Maximum plant height (5.23 m) was recorded in 5 m x 3 m spacing, whereas maximum stem girth (59.3 cm) was found in 6 m x 5 m spacing. At the age of ten years, maximum fruit yield (96.0 kg/plant) was recorded in 6 m x 6 m spacing. However, maximum yield per hectare (327.4 q) was found in 6 m x 4 m spacing, which was significantly higher over all other treatments except 5 m x 5 m spacing. Maximum fruit weight (79.9 g and 115.0 g) was recorded at 6 m x 6 m spacing during rainy and winter seasons. Total soluble solids (TSS) of fruits were recorded maximum (10.5 °Brix) at 6 m x 5 m spacing during the rainy season, whereas it was maximum (11.5 °Brix) at 6 x 6 m spacing during the winter season. During both seasons, the ascorbic acid content of fruits was found maximum (163.7 and 192.7 mg/100 g pulp) at 6 m x 5 m spacing.
