A field study was carried out at Soil Conservation and Water Management Farm of C.S. Azad University of Agriculture and Technology, Kanpur during two consecutive years in rabi 2014-15 and 2015-16 to assess the effect of different moisture conservation practices on growth and yield of linseed varieties under rainfed condition of Central Uttar Pradesh. The soil of the experimental area was Sandy Loam having Bulk density 1.36 Mg m⁻³, particle density 2.60 Mg m⁻³, water holding capacity 29.70%, field capacity 18.6%, porosity 47.7%, pH 7.9, electrical conductivity 0.37ds m⁻¹ at 25°C, organic carbon 0.30%, Total N 0.027%, available N 170.5 kg ha⁻¹, P2O5 16.4 kg ha⁻¹, 180.1 K₂O kg ha⁻¹ and S 8.80 kg ha⁻¹. The experiment was conducted in Randomized Block Design with 3 replications. The treatments consisted of 3 varieties i.e. T-397, Padmini and Shekhar along with 3 moisture conservation practices i.e. control or farmer´s practice, dust mulching created by hand hoe after one weeding by khurpi at 20 DAS and organic residue mulch (paddy stover) @ 4 t ha⁻¹ at 20 DAS were tested in the experiment. Based on two years study it was concluded that `Shekhar´ variety of linseed proved to be the most promising in production, root development, water use efficiency, net return and benefit: cost ratio, compared to `Padmini´ and T-397 varieties under rainfed condition while among moisture conservation practices, application of organic residue mulch @ 4 t ha⁻¹ on soil surface in between the crop rows at 20 days after sowing was found to be more remunerative in comparison to dust mulch and farmer´s practice (one weeding by khurpi) on sandy loam soil under rainfed condition at Kanpur.
