Abstract:

Vadavathur in Namakkal District is a drought prone village. The annual rainfall is 400 mm. In Vadavathur village, small onion is cultivated in two main seasons viz., Early kharif (May – August) and Rabi (November – December). Generally small onion is propagated by means of bulbs. However, NICRA village Vadavathur experienced aberrant rainfall situations with minimum rainy days for the past 5 years during sowing season especially during Rabi impacting adversely small onion production and livelihood of farmers. It appears that failure of rain and prolonged dry spells in November – December is responsible, as sowing of small onion is delayed with resultant adverse affect on productivity. Delay in sowing of small onion affects productivity in terms of delayed sprouting, slow growth of vegetative phase and reduction in yield. To mitigate these problems, KVK, Namakkal established staggered community small onion var. Co (On) 5 nursery during October in an area of 0.4 ha covering 20 farmers as a local adaptation strategy at the village level to combat the problem experienced by farmers during deficit rainfall seasons. Majority of the farmers could take up transplanting using seedlings from the 1st and 2nd nursery raised on 1st and 15th October. Highest bulb yield of 77 gm/plant, 22.3 tonnes /ha and benefit cost ratio of 3.4 was obtained by transplanting of onion seedlings which coincides with rainy days during November when compared to bulbs directly sown during December.
