Validation of Rapeseed-mustard Varieties/Line in High Land for Development of Rapeseed/ Mustard-Fallow-T. Aman Pattern of Sylhet in Bangladesh
Journal Title: Asian Journal of Advances in Agricultural Research - Year 2017, Vol 2, Issue 2
Abstract
Aims: To select high yielding variety(s) of rapeseed-mustard suitable for cultivation in the high land areas under partially irrigated conditions after harvest of T. Aman rice. Study Design: Split plot. Place and Duration of Study: Farmer’s fields at Sylhet, Bangladesh during November 2014 to March 2015. Methodology: A split plot design was used in the experiment assigning factor A. Irrigation levels viz. i. One irrigation at 25 DAS & ii. Two irrigation at 25 DAS and 55 DAS in the main plot and factor B. Rapeseed-mustard varieties viz. i. Tori-7, ii. BARI sarisha-13 (B. napus), iii. BARI sarisha-14 (B. campestris), iv. BARI sarisha-15 (B. campestris), v. BARI sarisha-16 (B. juncea), vi. Advanced line Nap-205 and vii. BINA sarisha-4 (B. napus) in the sub-plot. Fertilizers were applied at the rate of 120-36-90-27-6-3-0.8 kg ha-1 of N, P, K, S, Mg, Zn and B, respectively. Results: Results indicated that yield and yield contributing characters did not differ significantly due to irrigation levels because of rainfall at pod filling stage. Yield and yield contributing characters differed significantly among the varieties. The variety BARI sarisha-16 produced the highest seed yield (993 kg ha-1) which was significantly different from the others. BINA sarisha-4 produced the second highest seed yield (898 kg ha-1) while the lowest (645 kg ha-1) was produced by the variety Tori-7. BARI sarisha-16 required the maximum days (89.3) for maturity but Tori-7 and BARI sarisha-14 had the minimum days (76.3 & 77.5 days respectively). There was no significant variation due to combined effect of variety and irrigation level on yield and yield attributes. Seed yield was positively correlated with plant height, siliqua plant-1 and 1000-seed weight. Conclusion: Mustard varieties BARI sarisha-16 and BINA sarisha-4 with high seed yield potential may be well accommodated for developing Rapeseed/Mustard-Fallow-T.Aman rice cropping pattern.
