Abstract:
The present investigation entitled “Effect of planting date and INM on growth and yield in mint (Mentha arvensis L.) during Summer season under north coastal plains of Andhra Pradesh” is carried out at COH, Parvathipuram, Dr. Y.S.R. Horticultural University, during Summer season 2021. The experiment was laid out in factorial randomized block design with combinations of four planting dates (first fortnight of February, second fortnight of February, first fortnight of March and second fortnight of March) and four nutrient doses (Nl - 100% RDN, N2 - 75% RDN+ (12.5% FYM + 12.5% Vermicompost) + Rhizobium + PSB + KMB, N3 - 50% RDN + (25% FYM + 25% Vermicompost) + Rhizobium + PSB + KMB and N4 - 100% organic (50% FYM + 50% Vermicompost) in Summer season. The results revealed that growth parameters like plant height (66.75 cm), plant spread (91.79 cm), number of primary branches (31.93) and number of secondary branches (7.63 respectively) number of leaves per plant (1073.98 at 120 DAP, 790.93 at 150 DAP) and yield parameter fresh herbage yield per plant (106.96 g plant-1 at first harvest, 66.84 g plant-1 at final harvest) recorded maximum when crop planted on first and second fortnights of February. Among different treatment combinations N2 followed by N3 was superior in terms of growth and yield which recorded maximum plant height (66.80 cm), plant spread (89.20 cm), number of primary branches (27.57) and number of secondary branches (7.29) number of leaves per plant (925.75 at 120 DAP, 641.95 at 150 DAP) and yield parameter fresh herbage yield per plant (99.16 g plant-1 at first harvest, 62.89 g plant-1 at final harvest).
