Abstract:

The present investigation was undertaken to grow vegetable crops during extreme winter condition in north Sikkim condition where snowfall is the biggest problem in vegetable production. Very little research scientific cultivation of vegetable has been conducted in the past and until now scientific production of vegetable is not available. By keeping the above point, an experiment was conducted during 2017-18 and 2018-19 to study the effect of onion cultivation under plastic low cost low tunnels for restricting over winter in eastern Himalayan region at farm of College of Agricultural Engineering and Post-Harvest Technology, Ranipool, Sikkim. The experiment was laid in factorial randomized block design with 10 treatments in three replications. The treatments comprised the three different height of low tunnel i.e., 70 cm (H1); 85 cm (H2) & 100 cm (H3), Four varieties of onion i.e F1 hybrid “Rani” -V1, , Nasik red - V2 , “Minar” -V3, Leader –V4 and control (open) condition V1, V2, V3, V4. The results revealed that the growth parameter and yield attributing characters were significantly influenced by different low cost low tunnel height and onion varieties. It was seen that interaction of 100 cm low tunnel height and the variety “Nasik red” produced comparable height, number of leaves, survival percentage, bulbing percentage and bulb diameter. In case of Days to harvest, minimum was recorded in 100 cm tunnel height and the variety “minar”. Among all the treatment, 100 cm tunnel height with an onion variety “Nasik Red” showed better performance for all the parameter studied and can be considered basis for studying the effect of other agronomic practices.
