Ultra high density planting for higher productivity in guava
A research experiment was conducted at ICAR–Central Institute for Subtropical Horticulture, Lucknow (U.P.) farm under AICRP on Fruits. Trees of guava (Psidium guajava L.) cv. Lalit were planted in 2012 at 1.0 m x 1.0 m, 1.5 m x 1.5 m, 2.0 m x 1.0 m and 2.0 m x 1.5 m spacing. On the basis of results obtained at two years after planting, tree spacing of 2.0 m x 1.5 m exhibited highest trunk cross-sectional area (2.18 cm2), fruit yield in rainy and winter seasons (10.32 and 27.04 tonnes ha-1, respectively) and yield efficiency (3.44 kg cm-2), besides exhibiting highest quality parameters (highest fruit length, thickness and total soluble solids and lowest titrable acidity) in both the seasons.
