Abstract
The present investigation entitled “Performance of winter crops under eucalyptus (Eucalyptus tereticornis) based agroforestry system” was carried out at the research area of Department of Forestry, CCS Haryana Agricultural University, Hisar during winter season of 2017-18 to study the effect of 3 year old eucalypts plantation spaced at 7 × 3 m on growth and yield parameters of winter season crops vz. Wheat (Triticum aestivum), Barley (Hordeum vulgare), Oat (Avena sativa), Mustard (Brassica juncea) and Berseem (Trifolium alexandrinum). In this study, the minimum per cent reduction in moisture content was found at 3.5 m away from eucalypts tree line as compared to other distances near the tree line. However, the moisture content increased with the increase in soil profile. In eucalypts based agroforestry system the maximum per cent decrease in light intensity was 55.8 over control during the month of February, however, the minimum reduction (44.8%) in light intensity was in the month of March. Growth and yield attributing parameters of all the winter crops under study were affected significantly under eucalypts plantation. The yield of winter crops was also significantly reduced in association with eucalypts plantation over to control. Among winter crops the maximum reduction in grain yield of wheat was 18.6% under eucalypts based cropping system and it followed the order: mustard (17.64%), barley (12.5%), oat (9.32%) and berseem (8.1%) during the present investigation. In present study, berseem was found to be best shade tolerant crop followed by oat and barley under eucalypts based agroforestry system. Maximum net return (Rs. 102799.8/ha) was observed under eucalypts + berseem. The overall B:C ratio in all five winter crops under study was calculated higher in eucalypts based agroforestry system over control (sole crop).
