Keywords: EFFECT OF DIFFERENT NPK, ZINC AND SULPHUR LEVELS ON GROWTH, YIELD AND QUALITY OF JAPANESE MINT
Abstract: Mint (Mentha arvensis L.) belongs to the family Lamiaceae. The genus Mentha includes 25 to 30 species that grow in the temperate regions of Eurasia, Australia and South Africa (Dorman et al. 2003). It is found to be originated in mediterranean region. The mint species Mentha piperita commonly known as American peppermint, contains 50-55% of menthol and Mentha arvensis commonly known as Japanese mint, contains 80-85% menthol in it (Ozguven and Kirici, 1999). They are cultivated in different parts of the world. An investigation on “Effect of different NPK, zinc and sulphur levels on growth, yield and quality of mint (Mentha arvensis L.) var. Kosi” was carried out from October 2017 to February 2018 at PG Vegetable Block, College of Horticulture, Rajendranagar, Hyderabad. The experiment was laid out in Randomized Block Design, with treatments being 19 and 3 replications. The treatments had RDF of 100 % and 75 %, with and without combinations of sulphur and/or zinc. The study revealed that, the growth parameters were found highest in T9 in almost all stages of the plant growth, where in the plant height being 48.65 cm and 63.87 cm at 90 and 120 DAP respectively, number of laterals being 24.40 and 29.27 at 90 and 120 DAP respectively, lateral length of about 10.13 cm, 20.73 cm and 27.09 cm at 60, 90 and 120 DAP respectively, number of primary laterals being 19.60 and 22.27 at 90 and 120 DAP respectively, number of secondary laterals of about 4.80 and 7.00 at 90 and 120 DAP respectively, plant spread of about 111.87cm and 119.40 cm at 90 and 120 DAP respectively, leaf/lateral ratio of about 1.55 and 1.05 at 90 and 120 DAP respectively. Physiological parameters also showed that the plants treated with T9 showed highest values for leaf area of 13.26 cm2 and 19.73 cm2 at 90 and 120 DAP respectively. Leaf area index of about 2.27 and 4.07 at 90 and 120 DAP respectively, CGR (crop growth rate) of about 1.52 and 1.50 at 90 and 120 DAP respectively. Accordingly, yield parameters were also found to be highest in T9, where 1000 fresh leaf weight and 1000 dry leaf weight was about 258.4 g and 92.50 g, respectively. Similarly, fresh herb yield and dry herb yield was about, 6.59 kg and 2.09 kg/plot respectively. Quality parameters were also found to be highest in T9 (RDF 100 % + Zn 25 kg + S 25 kg ha -1). Chlorophyll content of about 77.77, essential oil of about 1.27, menthol content of about 80.70 and oil yield of about 12.73 ml/Kg. Least was found in control in all parameters. According to the present study, it reveals that Japanese mint plants treated with T9 showed high vegetative, yield and quality parameters. Plants treated with 100 % RDF proved better results compared to 75 % RDF, with or without sulphur and/or zinc. Apart from this, RDF alone showed least performance in all parameters in almost all stages of its growth compared to RDF with zinc and/or sulphur combinations. And the lowest performance was found in untreated plants
