Effect of fertilization on yield of Sub-tropical humid range lands I-Balakot study
Sultan Maqsood Khan
ABSTRACT
Four fertilizer treatments namely control, 50 kg nitrogen per hectare in urea, 50 kg of phosphorus per hectare in single super phosphate and 50 kg N+50 kg P per hectare in urea and single super phosphate were applied to range vegetation in subtropical humid zone at
Balakot village of Mansehra District. Nitrogen and phosphorus mixture doubled total forage and grass production and many times increased the production of desirable species, undesirable species, Chrysopogon aucheri and Cymbopogon martini. However, both nitrogen and phosphorus, when applied separately had no effect on the production of total forage, grass, any palatability class or any important forage species. No fertilizer treatment appreciably affected the forage production of intermediate species, Themeda anathera and Heteropogon contortus.
