SHAKHAWAT A field experiment was conducted of the farmer field in polder 30 at Basurabad village, Batiaghata, Khulna during July to December 2016 in order to develop fertilizer management techniques for HYV rice under tidal ecosystem prevailing in the polders of the coastal zone of Bangladesh. The experiment was comprised three rice varieties viz. BRRI dhan51, BRRI dhan72, and kumragor local T. aman rice and six fertilizer doses viz. No N + No P K S Zn(N ), 50% recommended N + No P K S Zn (N 2 ) , 100% recommended N + No P K S Zn(N 1 3 ) 50% recommended N + 50% recommended P K S Zn(N 4 ) , , 100% recommended N + 50% recommended P K S Zn (N 5 ) , 100% recommended N + 100% recommended P K S Zn(N ) and The experiment was laid out in a split-plot design with four replication. The purpose of the experiment was to developed fertilizer management techniques for HYV rice under tidal ecosystem prevailing in the polder of the coastal zone and to find out optimum fertilizer dose of HYV Aman rice for polder ecosystem. Data on different yield contributing characters, growth, and yield were recorded. Interaction between varieties and fertilizer management showed a positive impact on growth, yield and yield attributes of aman rice. Varieties showed the significant variations on plant height, tillers hill -1 , panicle length, grains panicle -1 6 , thousand grains weight, grain yield, straw yield, biological yield and harvest index. BRRI dahn51 gave the highest grain yield (5.39 tha -1 ). Fertilizer management also significantly influenced the growth and yield attributes of aman rice. The highest grain yield (4.98 t/ha) was observed in N . Interaction between variety and fertilizer management doses significantly influences plant height, tillers hill 6 -1 , panicle length, grains panicle , thousand grains weight, grain yield, straw yield, biological yield and harvest index. The highest grain yield (6.30 t ha -1 ) was recorded from the V treatment combination which was statistically similar with V 1 N . The highest filled grain panicle -1 (137.75) was observed in V treatment, biological yield (12.35 tha 1 N 5 -1 5 . Straw yield (8.98 tha ) was observed in V 3 -1 1 N 6 ) was higher in V N and harvest index (56.13 %) was higher in V 1 N 1 treatment. It may be concluded that V 1 treatment showed best result in the tidal ecosystem of the polder coastal zone A Thesis Submitted to the Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka, in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE (MS) IN AGRONOMY 2016-01-01T00:00:00Z http://localhost:8080/handle/123456789/589 POLYETHYLENEGLYCOL (PEG) INDUCE CHANGES IN GERMINATION, SEEDLING GROWTH AND WATER RELATION BEHAVIOUR OF WHEAT UNDER SALT STRESS CONDITION MOST. FAIJUNNAHAR An experiment was conducted at Laboratory of Department of Agronomy, Sher-eBangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207 during the period from October 2016 to December 2016. A set of experiment was conducted in three different experiments. The experiment was laid out in a Completely Randomized Design (CRD) with five replications. Four wheat genotypes namely- ESWYT 5, ESWYT 6, ESWYT 7 and BARI gom 28 were used as test crop and different priming chemicals such as PEG, salt (NaCl) and distilled water were utilized for osmo and hydro priming. The data on germination parameters of wheat like germination percentage and growth parameters like root length, shoot length, dry weight and vigour index. Data were analyzed using a computer software MSTAT-C. The significance of difference among the treatments means was estimated by the Least Significance Difference (LSD) at 1% level of probability. The first experiment was carried out to find the effect of different concentration of PEG on germination and growth behavior of four wheat genotypes (ESWYT 5, ESWYT 6, ESWYT 7 and BARI gom 28) without any stress condition. It was found that ESWYT 5 showed the highest germination rate (95.30%), shoot length (168.20 mm), root length (158.30 mm), shoot dry weight (0.0522 mg), root dry weight (0.0432 mg), relative water content (95.05%), water retention capacity (16.18) and vigour index (311.30) with primed seeds with 10% PEG solution for 12 hours. The second experiment was conducted to optimization of pre-sowing priming time on the germination and growth behavior of wheat genotypes. It was observed that ESWYT 5 with 10% PEG primed seeds for 9 hours gave the highest germination rate (83.33%), shoot length (181.1 mm), root length (145.0 mm), shoot dry weight (0.0536 mg), root dry weight (0.0432 mg), relative water content (91.45%), water retention capacity (19.94) and vigour index (272.3). In the third experiment germination and growth behavior of primed seeds of wheat genotypes (ESWYT 5, ESWYT 6 and BARI gom 28) under salt (NaCl) stress condition were evaluated. It was observed that highest germination rate (93.81%), shoot length (157.80 mm), root length (124.6 mm), shoot dry weight (0.037 mg), root dry weight (0.0414 mg), relative water content (89.13%), water retention capacity (22.32) and vigour index (264.7) were obtained from ESWYT 5 under primed seeds placed without salt. But under salinity stress, the highest germination rate (87.62%), shoot length (154.20 mm), root length (118.50 mm), shoot dry weight (0.0349 mm) and root dry weight (0.0393 mg), relative water content (85.61 %), water retention capacity (21.40) and vigour index (238.9) were achieved from ESWYT 5 under primed seeds placed with 5 dsm A Thesis Submitted to the Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka, in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE (MS) IN AGRONOMY 2016-01-01T00:00:00Z http://localhost:8080/handle/123456789/588 IMPACT OF ADDED FOLIAR SPRAY OF UREA AND BORON ON GROWTH AND YIELD OF MUNGBEAN PERVIN, MST. LATA The experiment was conducted at the Agronomy research field, Sher–e- Bangla Agricultural University, Dhaka, during the period from March 2016 to May 2016 to study the Impact of added foliar spray of urea and boron on growth and yield of mungbean varieties. The experiment consists of two varieties viz. V = BARI Mung-5 and V 2 = BARI Mung-6 and eight levels of fertilizer management viz. T ii 1 = Recommended fertilizer (RF), T = RF + Foliar spray (FS) of water at flower initiation (FI), T 3 2 = RF + Urea (2%) FS at FI, T 4 = RF + Boron (1%) FS at FI, T = RF + Urea (2%) + Boron (1%) FS at FI, T 6 = Urea (2%) FS at FI, T = Boron (1%) FS at FI and T 8 7 = Urea (2%) + Boron (1%) FS at FI. The experiment was laid out in Split Plot Design with three replications. In this experiment, both variety and combined foliar application of N and B had significant effect on most of the growth and yield contributing parameters irrespective of mungbean varieties.

In case of fertilizer management, the tallest plant (58.42 cm), highest leaves plant -1 (11.20), branches plant -1 (4.35) and nodules plant (87.33) were recorded from T (RF + Urea 2% FS at FI) but the highest above ground dry matter content plant -1 3 (25.27 g), pods plant -1 -1 (25.37), pod length (9.73 cm), seeds pod (10.43), 1000 seed weight (55.67 g), seed yield (1121.00 kg ha ), stover yield (1467.00 kg ha -1 ) and harvest index (43.31%) were recorded from T (RF + Urea 2% + Boron 1% FS at FI). Regarding combined effect, the tallest plant (59.97 cm), maximum leaves plant -1 (11.30), branches plant -1 5 -1 (4.63) and nodules plant (88.33) were recorded from the treatment combination of V 2 T but highest above ground dry matter content plant -1 (25.52 g), pods plant -1 3 (25.89), pod length (10.40 cm), seeds pod -1 (10.46), 1000 seed weight (56.67 g), seed yield (1159.00 kg ha ), stover yield (1472.00 kg ha -1 ), biological yield (2631.00 kg ha -1 ) and harvest index (44.05%) were recorded from the treatment combination of V 2 T 5 -1 -1 -1 .So, BARI Mung-6 along with T (RF + Urea 2% + Boron 1% FS at FI) is suggested for yield improvement in mungbean cultivation.
