Performance of seed pelletization in Acacia leucophloea (Roxb.) under different soil types

Abstract

Acacia leucophloea seeds were pelleted with Diammonium phosphate (30g kg1 of seed), commercial micronutrients mixture (19.7g kg1 of seed), Rhizobium (50 g kg ' of seed), Sevin (2g kg ' of seed) and Trichoderma viride (4g kg ' of seed). The pelleted seeds along with unpelleted control were evaluated in calcareous, sandy loam, acidic and sodic soils, Pelleted seeds registered significantly higher germination and seedling vigour compared to unpelleted control under all soil types. However, higher germination and seedling vigour were recorded in calcareous soil. In the acidic soil also pelleted seeds recorded significantly higher germination and seedling vigour than the unpelleted control. Hence, pelleting of seeds could be recommended for augmenting germination and seedling vigour under adverse soil conditions.
