Abstract: An investigation was undertaken at College of Agriculture, Nagpur to study the effect of land configuration and irrigation levels on growth, yield attributes and yield of linseedduring rabi season of 2014-2015 in split plot design with twelve treatment combinations consisting of four land configurations viz., L1 (Flat bed), L2 (Ridges and furrow), L3 (Opening of furrow after two rows) and L4 (Broad bed furrow) and three irrigation levels viz., I1- One irrigation at flowering (40-45 DAS), I2- Two irrigations, one at flowering (40-45 DAS) and second at capsule formation (65-70 DAS) and I3- Three irrigations, one at vegetative (20-25 DAS), second at flowering (40- 45 DAS) and third at capsule formation (65-70 DAS) replicated three times. Linseed variety PKV NL-260 was used as a test crop. The soil was clayey in texture with pH 7.8 indicating slightly alkaline in reaction. Results showed that application of land configuration treatments significantly increased plant height, number of branches, dry matter accumulation plant-1 (g), seed yield (kg ha-1), straw yield (kg ha-1) and oil content (kg ha-1). Highest values of all the growth characters were recorded in land configuration treatment of broad bed furrow (BBF) but at par with treatment of ridge and furrow. Also seed yield (kg ha-1), straw yield (kg ha-1) and oil yield (kg ha-1) had higher values with BBF but at par with ridge and furrow. Results further revealed that application of three irrigations, one at vegetative stage, second at flowering and third at capsule formation recorded significantly higher values of growth parameters, seed yield (kg ha-1), straw yield (kg ha-1) and oil yield (kg ha-1) over treatment of one irrigation at flowering and was at par with two irrigations, one at flowering and second at capsule formation.. Higher moisture content was noticed in treatment of broad bed furrow (L4) among various land configuration treatments. The BBF recorded minimum consumptive use (105.68 mm). The higher water use efficiency was recorded by BBF (13.21 kg ha mm-1) followed by ridges and furrow (11.97 kg ha mm-1). The highest water use efficiency of (16.28 kg ha mm-1) was recorded in treatment (I3). Consumptive use increased to 175.73 mm when three irrigations were given one at vegetative stage, second at flowering and third at capsule formation.
Interaction effect of land configuration and irrigation levels were found to be non significant in respect of all yield parameters seed and oil yield.
