Determination of Nutrient Content of Guava Cv. ‘Pant Prabhat’ Affected by Different Canopy Heights and Planting Densities

Abstract

The study was conducted to determine the changes in nutrient composition of both affected by canopy heights, planting densities, and their interactions in comparison with both rainy and winter seasons. The experiment was composed of 4 different canopy heights [1.25m (H1), 1.5m (H2), 1.75m (H3), and unpruned (H4)] and 3 planting densities [5555 (D1), 3333 (D2), and (D3) 4444 plants ha-1] with total 12 treatment combinations laid out in factorial RBD was conducted. Fruits from the winter season were high in the nutrient content than in the rainy season. Canopy height H1 (1.75 m) recorded the maximum N, P, K, Zn, Cu, Fe and Mn (1.43%, 0.40%, 1.22%, 2.31 ppm, 2.28 ppm, 2.50 ppm and 1.31 ppm) in the winter season while, in the rainy season, maximum (0.88%, 0.35%, 0.98%, 2.07 ppm, 1.92 ppm, 2.14 ppm, 1.05 ppm) canopy height H3 (1.75m). Planting density D2 (3333 plant ha-1) recorded the maximum nutrient content for both seasons. It is therefore concluded canopy height H1 (1.25m) with planting density D2 (3333 plant ha-1) is best for producing fruits with high nutrient content for the winter crops.
