Abstract:Linseed is an industrial crop cultivated for its seeds, fibres and oil purpose. Linseed crop can met their requirement i.e. moisture and nutritional demand from stored soil moisture and residual fertility status in "utera" or "paira" system of cropping. On the basis of this fact an experiment was conducted on "Seed yield of linseed varieties grown as paira crop as influenced by dates of sowing" in red and laterite zone of West Bengal during rabi season of 2012-13 and 2013-14 at Rice Research Station, Bankura, West Bengal, India. Poor in organic matter content, available phosphate and bases, hard structure of iron and aluminium patterned as honeycomb are present in the subsurface regions of the profiles and kaolinite is the predominant clay minerals of red and lateritic zone (western part) of West Bengal. This experiment was laid out in a split-plot design with three replications and compared two factors (dates of sowing and linseed varieties). Objective was identifying the optimum date of sowing and suitable linseed varieties grown as "paira" crop under changed climate in red and laterite zone of West Bengal. as pooled value). Lowest seed yield (409. 3 kg ha -1 as pooled data) was recorded from Neela variety. From the present study it may be concluded that linseed sown on 15 th November is the best time and T-397 is the suitable linseed variety grown as "paira" crop under changed climate in red and laterite zone of West Bengal.

Nine lines, 3 testers and 27 F1 crosses of basmati rice (Oryza sativa L.) mated through Line × Tester mating Design to decipher the extent and nature of correlation between yield and yield contributing characters moreover quality traits were also included in the study. At the end of the experiment and subsequent statistical analysis it was deciphered that grain yield per plant has positive significant correlation with number of effective tillers per plant and hulling recovery which pointed that the number of effective tillers is an important trait that can be targeted as a selection criteria in yield improvement programmes in breeding of Basmati rice moreover quality traits like hulling recovery and milling recovery should also be emphasized specially in long-grained rice.
