Effect of micronutrient on growth and yield parameter of Mint (Mentha arvensis)

Abstract

The study was undertaken at the Floriculture Research Farm, College of Horticulture and Research Station, Sankara, Patan from February to June 2025, employing 10 treatments (T0 (Control), T1 (Zn @ 300 ppm), T2 (Zn @ 500 ppm), T3 (Zn @ 700 ppm), T4 (Cu @ 300 ppm), T5 (Cu @ 500 ppm), T6 (Cu @ 700 ppm), T7 (Fe @ 300 ppm), T8 (Fe @ 500 ppm), and T9 (Fe @ 700 ppm). The aim was to assess the influence of different micronutrient applications and concentrations on mint growth and yield. Data collected from the experiment were statistically analyzed, and the results are discussed. Result indicated that the application of micronutrients had a significant impact on Plant spread, leaf plant ratio and on both fresh and dry herbage yield of mint. The maximum plant spread recorded in T5 (Cu @ 500 ppm) 72.45cm, the maximum LPR recorded in T5 (Cu @ 500 ppm) 91.17%, highest fresh herbage yield was obtained in T8 (Fe @ 500 ppm) 302.62 g, For dry herbage yield, the maximum was recorded in T5 (Cu @ 500 ppm) 73.11 g, These findings indicate that Fe @ 500 ppm and Cu @ 500 ppm were the most effective treatments for enhancing mint yield.
