| dc.description.abstract | Sorghum (Sorghum bicolor (L.) Moench) locally known as Jawar or Chari is an important kharif season crop which is grown for both fodder and grains. Fertilizers constitute an integral part of improved crop production technology. Application of optimum quantity of phosphorus and potassium is important in improving quality and yield of forage sorghum. The present investigation was carried out to study the effect of phosphorus and potassium application on quality parameters. Sorghum variety HJ 541 was grown in field and different doses of phosphorus (15, 30. 45, 60 and 90 kg P2O5/ha) and potassium (20, 30, 40, 50 and 60 kg K2O/ha) were given. Plant/leaf samples were collected at 30 DAS, 50 DAS and 90 DAS. Biochemical parameters namely HCN, IVDMD, crude protein, nitrogen content, phosphorus content, potassium content, iron content, NDF, ADF, total soluble solids, total soluble sugars, reducing and non- reducing sugars, morpho- physiological parameters namely fresh weight, dry weight, stem girth, internode length and number of leaves and cell wall components namely cellulose, hemicelluloses, lignin and pectin were studied. It was observed that HCN content was less than permissible value (200 μg/g at fresh weight) with the application of phosphorus and potassium. IVDMD, crude protein, nitrogen content, phosphorus content, potassium content, iron content, total soluble solids, total soluble sugars, reducing and non- reducing sugars increased with the application of phosphorus and potassium. Maximum fresh and dry weight, stem girth internode length and number of leaves increased with the application of phosphorus and potassium. NDF, ADF, cellulose, hemicelluloses, lignin and pectin decreased with the application of phosphorus and potassium. The results obtained revealed that the quality of forage sorghum improved with the application of phosphorus and potassium. | en_US |
