Impact on Bulk density, infiltration rate and organic carbon as influenced by tillage practices and irrigation schedule of Linseed (Linum usitatissimum) grown after Rice of Chhattisgarh plain

Abstract

Linseed (Linum usitatissimum (L.) Griesb.) also known as flaxseed, is one of the most versatile and useful crop grown either for oil from seed or for fibre from stem. Linseed yields seed which is a rich source of both non-edible and edible oil. Ph.D research on “Agro-resource management studies on growth, yield, quality and economics of linseed (Linum usitatissimum Linn.) grown after rice in Alfisols of Chhattisgarh plains” was conducted during rabi seasons of 2009-10 and 2010-11 at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur with the specific objectives to study the effect of different tillage with varying levels of irrigation on growth, yield, nutrient uptake and economics of linseed. Two different experiments on linseed crop were undertaken during two consecutive rabi seasons of 2009-10 & 2010-11. The experiment was divided into horizontal and vertical plots under strip plot design. The horizontal plot was further divided into four tillage practices viz. zero tillage (T0), harrowing once (T1), rotavator once (T2) and conventional tillage (T3) and vertical plots were divided into four irrigation schedules viz. one irrigation after seeding (I0), one irrigation at 35 DAS (I1), two irrigations at 35 and 75 DAS (I2) and three irrigations at 0, 35 and 75 DAS (I3).
