Ultra high density planting for higher productivity in Guava

A research experiment was conducted at ICAR-Central Institute for Subtropical Horticulture, Lucknow (U.P.) farmunder 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 mx 1.5 m, 2.0 m x 1.0 mand 2.0 m x 1.5 m spacing. On thebasis 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.
