Abstract

A field experiment was conducted on waterlogged sodic soil to see the response on Acacia nilotica to silvicultural practices. The experiment consisting of 8 treatments (control, weeding, lopping, fertilizer application and their possible combinations) was laid-out in Randomized Block Design, replicated twice. Plant height recorded at six months interval and biomass after two and half years of treatment revealed that lopping increased the plant height but it was not beneficial to increase the biomass. Fertilizer application was found to increase plant height, circumference and biomass production of the plants. Response of weeding treatment was not promising.

Abstract

A field experiment was conducted in Randomized Block Design to see the response of Acacia nilotica to nitrogen (0 and 50 g N plant^-1) and phosphorus (0 , 25 , 50 , 75 and 100g phosphorus plant^-1) in water logged sodic soil. Results indicated that increment in the height and biomass production at two and half years age of Acacia nilotica plantation was not promising to nitrogen application. The application of phosphorus however , increased the plant height and its biomass. Application of 75 g plant^-1 phosphorus , was found to be optimum dose for ,Acacia nilotica in waterlogged sodic soils.
