FIELD VEGETABLE PRODUCTION IN CERTAIN MULTIPLE CROPPING PATTERNS IN RELATION TO DIFFERENT TIMES OF SOWING IN PUNJAB (INDIA)
The studies have revealed that three vegetable crops can be grown in a year on the same land, offering better returns in comparison with a rotation having two crops per year. A suquence of potato (seed crop, variety Kufri Chandramukhi, sown in the first week of October), carrot (seed crop, variety No. 29 sown in November and transplanted in the second week of January), okra (green pods, variety Pusa Sawani, sown in the second week of June) gave average yield of 320 q potato seed/ha, 10 q carrot seed/ha and 15 q okra green pods/ha. Other judicious vegetable sequences were Potato-Late cauliflower-chilli; Potato-muskmelon-radish; Potato-okra-early cauliflower; Pea (early crop)-tomato-okra and Radish-tomato-bittergourd.
The role of certain critical factors like proper selection of varieties and timeliness of cultural operations and special growing techniques has been discussed.
