Effect of farming conditions on bacterial wilt incidence in brinjal

Abstract

Brinjal is one of the important vegetable crops on account of its medicinal value. Crop is vulnerable to plethora of diseases of which bacterial wilt is most devastating disease in the tropical, subtropical and temperate regions of the world, causing heavy economic loss. The chemical control of the disease is very expensive and the only way to sustain cultivation is by growing bacterial wilt resistant varieties. Of late, cultivated resistant varieties are gradually succumbing to the disease. Thus, the experiment was conducted to evaluate new bacterial wilt resistant lines (27) under mid hill conditions of Himachal Pradesh. The experiment was laid down under conventional farming and zero budget natural farming conditions. Observation was recorded on plant survival and the lines were categorized according to Sitaramiah scale (1981). The results indicated that BRBWRES-1, BRBWRES-2, SM 6-7, Hisar Shyamal, Arka Keshav, Arka Nidhi, Haritha, Muktakeshi and Kashi Prakash manifested no bacterial wilt incidence and were categorized as immune. Thus, these lines can be recommended for cultivation in bacterial wilt prone areas.
