Influence of Date of Sowing and Cultivars on Growth and Yield of Fodder Oats (Avena sativa L.) in New Alluvial Zone of West Bengal

摘要

A field experiment was conducted during rabi season of 2007-2008 and 2008-2009 to study the influence of date of sowing and variety on growth and yield of fodder oats. The experiment, consisting of 18 treatment combinations having three levels of dateof sowing (15th Nov 30 Nov and 15lh Dec) and six levels of variety (NDO-1, Kent, JHO-822, OS-6, UPO-212 and JHO-851) was laid out in factorial randomized block design (FRBD) where each treatment was replicated thrice. Various growth attributes (viz. Plant height, number of tillers per plant, leaf area index and dry matter accumulation) and yield attributes (viz. green fodder, dry fodder and crude protein yield) of fodder oats were influenced significantly with different dates of sowing and variety. At75 DAS oat cv OS-6 recorded maximum plant height (123.85 cm), which was significantlyhigher than all other varieties. The maximum dry matter accumulation (313.48 g m2) of oat was recorded when sown at 15th Nov. The maximum dry matter was recorded in cv OS-6 (378.46 g m2) which was significantly greater than that of all other varieties. Significantly highest GFY (353.81 q ha~(-1)) was recorded when sown 15th Nov. The maximum crude protein yield (6.60 q ha ') was recorded in cv OS-6. A significant response from date of sowing and variety was found on total green and dry fodder yields of oats and crude protein yield.
