Abstract:

The experiment was carried out in Split plot design with three replications. In main plots treatment consisted of five planting pattern viz.,T1- Sole linseed, T2- Sole chandrasur, T3- Linseed +chandrasur (1:1), T4- Linseed +chandrasur (2:1), T5- Linseed +chandrasur (2:2) and four weed management treatment combination viz., W1- Oxadiargyl @ g ha-1 pre- emergence fb one hand weeding at 20 DAS, W2- Mechanical weeding by cycle hoe + hand pulling intra rows at 25 DAS fb one hand weeding at 40 DAS, W3- Hand weeding (20, 40 DAS), W4- Weedy check were assigned in sub plots. The findings revealed that planting pattern and weed management had significant influenced on weeds and weed indices. The significantly minimum total weed density and dry weight was recorded under T5-linseed+chandrasur (2:2) row ratio, but it was at par to T4- linseed + chandrasur (2:1) row ratio and T3- linseed + chandrasur (1:1) row ratio during both the years and on mean basis. As regards to weed management practices, significantly minimum weed density and dry weight was observed under W3 -Hand weeding (20, 40 DAS), but it was at par to W2-Mechanical weeding by cycle hoe + hand pulling intra rows (25 DAS) fb one hand weeding (40 DAS) during both the years and on mean basis. The minimum weed index (25.36, 27.78 and 23.15%) was recorded under W3- Hand weeding twice (20 and 40 DAS) and maximum weed smothering efficiency (73.79, 73.82 and 17.81%) was recorded under T5- linseed +chandrasur (2:2) row ratio followed by T4- linseed + chandrasur (2:1) row ratio recorded (69.50, 70.99 and 70.50%) and the minimum weed smothering efficiency (54.40, 56.92 and 55.86%) was recorded under T1- sole linseed during both the years and on mean basis, respectively.
