ULLAH, SHEIKH SALAMAT
A research work was carried out at the Agronomy Farm, Sher-e-Bangla
Agricultural University, and Dhaka during the period from November 2012 to
June 2013 in order to determine the suitable nitrogen source to observe the
growth performance with a view to increasing the grain yield by reducing
spikelet sterility in boro rice. The experiment comprised four sources of nitrogen
viz. no nitrogen, BRRI recommended dose of prilled Urea, Govt. approved dose
of mixed NPK and BARC recommended dose of urea super granule (USG), and
four varieties viz. BRRI dhan29, BRRI dhan58, BADC SL8H and Heera. The
experiment was set up in a split-plot design with three replications. Experimental
results indicated that nitrogen sources had significant effect on plant height,

, spikelet sterility (%), grain yield, straw yield, biological
yield and harvest index. The application of USG showed the highest grain yield
(8.64 t ha

) and the lowest spikelet sterility (%) than any of nitrogen and other
sources of nitrogen treatments. All the studied characters except harvest index
varied significantly due to varieties. Among the varieties, BRRI dhan29 out
-1 yielded Heera, BADC SL8H and BRRI dhan58 by 0.85, 1.13 and 1.98 t ha
,
respectively which is mainly attributable to the highest number of grains panicle
1
(98.57) and markedly lower level of spikelet sterility (11.13 %). The
combination of the USG application and BRRI dhan29 had the higher
performance in terms of producing the highest grain yield by significant
reduction of spikelet sterility (%) among the interaction effects.

HAQUE, MD. NAZMUL
A pot experiment was conducted at the Agronomy research field, Sher-e-Bangla Agricultural University, Dhaka from November 10, 2012 to February 18, 2013 to find out the effect of 3 different Arsenic (As) levels viz., As0 (control), As1 (25 mg As kg-1 soil), As2 (50 mg As kg-1 soil) on growth, yield and quality of fourteen potato varieties viz., V1 (Diamant), V2 (Cardinal), V3 (Asterix), V4 (Granola), V5 (Lady Rosetta), V6 (Courage), V7 (BARI TPS-1), V8 (Meridian), V9 (Felsina), V10 (Laura), V11 (Quincy), V12 (Sagitta), V13 (Rumana), V14 (Jam Alu). The different levels of As had significant effect on most of the growth, yield and quality contributing parameters of potato irrespective of varieties. All parameters studied in this experiment were decreased with the increasing As levels except number of tubers hill-1, non-marketable yield plant-1, 28-45 mm and <28 mm sized tuber, total soluble solids. Among the fourteen potato varieties, the yield of potato negatively affected by As contamination. The variety ‘Felsina’ produced maximum yield plant-1 (426.2 g) whereas, ‘Jam Alu’ showed minimum yield plant-1 (77.15 g) irrespective of As levels. The variety ‘Rumana’ accumulated maximum As in peel (2.95 mg kg-1) and in flesh (0.189 mg kg-1) while, ‘Jam alu’’ loaded minimum in peel (2.31 mg kg-1) and ‘Cardinal in flesh (0.100 mg kg-1). The results showed that though most of the parameters were decreased with the increasing As levels but most of the parameters remained statistically similar up to 25 mg As kg-1 soil and thereafter drastically decreased. The results also revealed that the yield of potato varieties were decreased with increasing As levels but the accumulation of As increased with increasing As levels. In case of As accumulation, peel always accumulated maximum As than that of tuber flesh. Among the treatment combinations, ‘Felsina’ cultivated with 0 mg As kg-1 soil performed the best results and the same variety with 25 mg As kg-1 soil also showed the statistical similar results in terms of growth and most of the yield parameters. In contrary, the maximum As accumulation both in peel 6.43 mg kg-1 and in flesh 0.313 mg kg-1 were found in ‘Rumana’ at 50 mg As kg-1 soil. Though the variety ‘Felsina’ produced maximum yield but the accumulation of As was also high in peel (6.02 mg kg-1) and in flesh (0.247 mgkg-1), respectively. On the basis of As accumulation, the variety ‘Cardinal’ and ‘Diamant’ were suitable for cultivating up to 25 mg As kg-1 contaminated soil though these two varieties produced little bit lower yield (399.0 and 436.1 g plant-1, respectively) than that of ‘Felsina’ (448.8 g plant-1).
