Description |
Introduction of Stylosanthes hamata in natural pasture under annona (Annona squamosa L.) trees was found significantly superior in terms of total dry forage (3.20, 3.89 and 3.95 tonnes/ha) and crude protein yield (255.9, 311.7 and 305.1 kg/ha) than S. scabra in first, second and third years, respectively. Dry forage yield (3.26, 3.86 and 3.98 tonnes/ha) and fruit quality of annona (TSS °B 26.4) was significantly increased with the application of 40 kg P2O5 + 30 kg K2O/ha as compared to control treatment. However, crude protein yield (269.9, 321.1 and 325.5 kg/ha) and fruit yield (5.72, 6.11 and 7.60 kg/tree) was significantly increased up to 60 kg P2O5 + 45 kg K2O/ha. Application of phosphorus and potash also had a positive effect on maintenance of legumes population in natural pasture. Persistence of legumes were 86.9 and 81.6% in the treatment where phosphorus and potash were applied @ 60 P + 45 K kg/ha as compared to control treatment (75.7 and 63.3%) during the second and third years, respectively. Maximum net returns and benefit: cost ratio were obtained by introduction of S. hamata along with application of 60 kg P2O5/ha +45 kg K2O/ ha in natural pasture under annona trees during all the 3 years. Nutrients uptake by different species were also increased with the application of phosphorus and potash in natural pasture
