Yield Attributes and Economics of Linseed (Linum usitatissimum L.) Cultivars under Irrigated Uphill Condition of Indian Himalayan Region in Nagaland

Background: Linseed is an upright annual herbaceous plant that grows up to a height of 30-120 cm with slight glabrous, grayish green stem while flax types grow to a height of 80-120 cm with straight culms and fewer secondary branches near the top of the stem. The colour of linseed flowers depends on the varieties. According to Vavilov, the small-seeded type is grown primarily for oil purposes while the bold seeded type is grown primarily for fibre purposes. Methods: The experiment was laid out in Randomized Block Design with three replications and consisted of seven linseed varieties viz., JLS-95, RLC-153, LSL-93, T-397, Shekhar, Priyam and Parvati. Result: Among all the varieties JLS-95 produced higher yield attributes viz., number of capsules plants-1, seed yield (Kg ha-1) and stover yield as well was statistically superior in variety JLS-95 over the other varieties. The variety JLS-95 recorded maximum gross returns, net returns and B:C compared to the other varieties.
