SUMMARY
The present investigation entitled “Effect of Foliar Nutrient supplementation and Nutrient Levels on Growth and Yield of Multicut Fodder Sorghum (Sorghum bicolor (L.) Moench)” was conducted at Instructional Farm, College of Agriculture, Vellayani, Thiruvananthapuram, Kerala from January to July 2025 to study the influence of foliar nutrient supplementation and nutrient levels on growth and yield attributes of multicut fodder sorghum. The field experiment was laid out in randomized complete block design with (3 x 3) + 1 treatment, replicated thrice. The treatment combinations included three levels of source of nutrients (S) (s1 – DAP, s2 – KNO3, s3 – 19:19:19) and three different nutrient levels (N) (n1 – 50% RDN, n2 – 75% RDN, n3 – 100% RDN), compared against the control treatment (KAU POP 2024). The variety used for the study was CSH 24MF, released from GB Pant university of Agriculture and Technology. The results revealed that the treatment with DAP as foliar nutrient source along with 75% RDN proved its superiority by registering higher growth and yield attributes such as plant height, stem diameter, leaf area index, leaf: stem ratio, total green and dry fodder yield.
Key words: Multicut sorghum, foliar nutrient supplementation, recommended dose of nutrients and fodder yield
