Effect of Different Sulphur Sources on Growth and Yield Attributes of Linseed (Linum usitatissimum L.) under Dhampur Agro-climatic Conditions

Abstract

A field experiment was conducted during the rabi season of 2024-25 at the Agronomy Research Farm, R.S.M. (P.G.) College, Dhampur, Bijnor (U.P.) to evaluate the effect of various sulphur sources on growth and yield attributes of linseed. The experiment was laid out in a randomized block design with seven treatments and three replications. Results revealed that the foliar spray of nano sulphur (0.5%) at 30 DAS and flowering stage (T₅) recorded the highest values for growth parameters [plant height (71.3 cm), number of leaves (183.1 plant-1), leaf area (52.6 plant-1), number of branches (19.13 plant-1) and yield attributes [number of capsule (37.7 plant-1), number of seed capsule (8.9 capsule-1), test weight (8.1 g)] followed by foliar application of sulphur fertilizer (0.5%) at 30 DAS and flowering stage (T₇). It is concluded that foliar application of nano sulphur at 30 DAS and flowering stage can be recommended for enhancing productivity and profitability of linseed under the agro-climatic conditions of Dhampur.
