Abstract

The present field investigation (kharif 2021 and 2022) studied the effect of nutrient management systems on growth attributes of sweet sorghum involving three levels of nitrogen (N) (60,120,180 kg/ha), two levels of potassium (K) (40,60 kg/ha), two levels of boron (B) (1, 2 kg/ha), recommended dose of NPK (120:60:40), RDF + FYM @ 10t/ha and an absolute control in a randomized complete block design. Application of NKB at the rate of 180, 60 and 2 kg/ha resulted in considerably higher values for plant height, stem diameter, number of tillers/m2, average internode number and internode length/stem throughout the cropping seasons (30, 60, 90 days after sowing and at harvest). Similarly, correlation studies revealed that growth attributes such as plant height, stem diameter, tillers/m2, internode number and length were positively correlated with juice yield of sweet sorghum. The findings highlighted the significance of balanced fertilization particularly high N application in enhancing sweet sorghum growth.
