| dc.description.abstract | The field experiment was conducted at Fodder Unit, CSK HPKV, Palampur (Himachal Pradesh) during kharif 2021 to study the effect of micronutrients and plant growth regulators on productivity and quality of fodder sorghum. The soil of experimental field was silty clay loam in texture; acidic in medium; low in available nitrogen and DTPA extractable zinc; medium in available phosphorus and potassium and fair in available boron. The experiment was laid out in randomized block design with three replications, consisting twelve treatments i.e., T1- triacontanol 10 ppm (30 DAS), T2- salicylic acid 100 ppm (30 DAS) , T3- 5 kg Zn ha-1 , T4- 2 kg B ha-1 , T5- 5 kg Zn + 2 kg B ha-1 , T6- 5 kg Zn ha-1 + triacontanol 10 ppm (30 DAS), T7- 5 kg Zn ha-1 + salicylic acid 100 ppm (30 DAS), T8- 2 kg B ha-1 + triacontanol 10 ppm (30 DAS), T9- 2 kg B ha-1 + salicylic acid 100 ppm (30 DAS), T10- 5 kg Zn + 2 kg B ha-1 + triacontanol 10 ppm (30 DAS), T11- 5 kg Zn + 2 kg B ha-1 + salicylic acid 100 ppm (30 DAS) and T12- water spray at the time of PGRs application. Application of 5 kg Zn + 2 kg B ha-1 + triacontanol 10 ppm (30 DAS) resulted in better plant height (cm), mean stem diameter (cm), shoot number (m-2 ), leaf stem ratio, dry matter accumulation (g m-2 ), higher green and dry fodder yields (t ha-1 ), nutrient uptake (N, P, K, S & B), crude protein, acid detergent fibre and neutral detergent fibre yield of sorghum. Significantly higher B and S content was recorded with soil application of 2 kg B ha-1 . Soil application of 5 kg Zn ha-1 resulted in significantly higher Zn content; however significantly higher uptake of Zn was recorded with the application of 5 kg Zn ha-1 + salicylic acid 100 ppm (30 DAS). Soil properties viz., soil pH, bulk density, available N, P, K, S and B remained unaffected under different treatments however Zn content in soil was recorded significantly higher with application of 5 kg Zn + 2 kg B ha-1 + triacontanol 10 ppm (30 DAS). Application 5 kg Zn + 2 kg B ha-1 + salicylic acid 100 ppm (30 DAS) resulted in higher net returns (59.40 ₹ x 103 ), while higher benefit-cost ratio was obtained with the application of 5 kg Zn ha-1 + salicylic acid 100 ppm (30 DAS). | en_US |
