Study on mint (Mentha arvensis) Intercropping with maize (Zea mays) and Wheat (Triticum aestivum)

Abstract

The present work was undertaken to Study the Mint (Mentha arvensis) intercropping with Maize (Zea mays) and Wheat (Triticum aestivum). The field experiment was conducted at Khalsa College Amritsar. Eight treatments were studied viz. T1, Mint sole T2, Mentha sown on beds as relay in bed planted wheat, T3, Mentha sown in furrow as relay in beds planted wheat, T4, Mentha on beds after the harvesting of wheat, T5, Mentha in furrow after the harvesting of wheat, T6, Maize plus Mint on beds, T7, Maize plus Mint in furrow, T8, Maize sole. The result revealed that in the treatment T1 sole mint shows higher herbage yield (205.4 q/ha) and oil yield (132.4 kg/ha) as compare to intercropping with wheat and maize in treatments T2, T3, T6, T7 respectively. Sole mint also produce higher growth and yield parameter than crop sown in nursery transplanted in the month of April in treatments T4 and T5. However Land equivalent ratio (LER), Area time equivalent ratio (ATER), Monetary advantage index (MAI) were higher in intercropping. Descending order of herbage yield was from T1 (205.4 q/ha)> T3 (192.5 q/ha)> T2 (177.5q/ha) > T4 (165.2 q/ha) > T5 (145.2 q/ha) > T7 (140 q/ha) > T6 (124.2 q/ha) respectively.
