Studies on tillering habit and yield of some Kharif rice cultivars as influenced by transplanting date under terai region of West Bengal.
Abstract: A study was conducted at the research farm of Uttar Banga Krishi Viswavidyalaya Pundibari, Cooch Behar, West Bengal to find out the effect of transplanting date on yield of eight kharif rice cultivars during of two consecutive years, 2005 and 2006. The experiment was laid out in a split plot design with three replications. Results showed that due to higher conversation of light energy into chemical energy and its subsequent translocation from source to sink in earlier followed by middle and late grain yield was found also higher in the sequence of earlier > middle > late. All the cultivars under the different transplanting dates are taking more or less the same time to get maturity. Irrespective of cultivars rice grain yield decrease over 300 kg/ha for every 20 days delay in transplanting. The grain yields in short (Hira, 1.31 t/ha) and mid duration (Mala, 1.94 t/ha : Satabdi, 1.96 t/ha) varieties were lower than of long duration (Swarna, 2.41 t/ha) varieties, which may due to lesser number of productive tillers per m2, number of field grains per panicle and test weight.
