The two factorial experiment was laid out in a CRD design with three replications. Factor A: two varieties [V ii 1 - BRRI dhan29 and V - Binadhan-8] and Factor B: different arsenic doses [As 0 = No arsenic applied, As =10 ppm As, As 2 =20 ppm As, As 3 =40 ppm As, As 4 =60 ppm As, As =80 ppm As]. Arsenic (As) was added from Sodium Arsenate (Na 2 HAsO 4 .7H 2 5 O). However, Binadhan-8 showed better performance than BRRI dhan29. Treatment with no arsenic (As gave higher results in most growth, yield and yield related parameters. In case of interaction, Binadhan-8 and the treatment As 0) gave longer panicle, higher number of filled grains panicle -1 , 1000-grain weight, grain yield and straw yield. K, Na, and As content in grain showed statistically significant difference due to the varietal effect in most cases except Cu. The treatment As gave higher Na and Cu content whereas the lowest from As 3 . 1 The maximum As content in grain, straw and root was found in As 5 whereas the minimum from As treatment. In interaction, the maximum As content in grain, straw and root was found in V 1 As 5 0 whereas the minimum As content in grain, straw and root was observed from V 2 As treatment. Arsenic contamination significantly decreased almost all the growth, yield contributing character and nutrient contents. However, the effect was quite varied with the rice varieties. The As concentration in grain, straw and root of these rice varieties increased with increasing rate of As addition. Binadhan-8 had the lowest As concentration and BRRI dhan29 showed the highest As concentration in grain, straw and root. Therefore, it suggests that arsenic reduces the yield of rice. Therefore it is needed to screen out tolerant or resistant varieties as well as find any possible ways to obliterate arsenic uptake in rice.

RABIUL ISLAM An experiment was conducted at the experimental site of Sher-e-Bangla Agricultural University (SAU) during the period from November 2016 to March 2017 to study the influence of irrigation and foliar application of boron fertilizer on growth, yield and nutrients content of BARI Gom 26. The experiment consists of two factors such as three irrigation level viz. (i) I 0 (No irrigation; Control), (ii) I (One irrigation given at crown root initiation (CRI) stage; 18 DAS), (iii) I ii 2 1 (Two irrigations, one at CRI stage; 18 DAS and other at panicle initiation; PI stage; 55 DAS) and four levels of foliar application of boron (B) viz. (i) B ha -1 ), (iii) B 2 (2.0 kg H 3 BO 3 ha -1 0 (0 kg H 3 ) and (iv) B BO 3 3 ha -1 ; Control), (ii) B (2.5 kg H 3 BO 3 ha -1 ). The experiment was laid out in a randomized complete block design with three replications. Results indicated that irrigation treatment I (Two irrigations at CRI stage and PI stage) with the combination of B 2 (2.0 kg H 3 2 BO 3 ha -1 1 (1.5 kg H ) gave the highest dry weight plant (34.76 g), spike length (17.65 cm), number of spikelets spike -1 (61.20) number of grains spike -1 (41.63), 1000 grain weight (48.82 g), grain yield (4.66 t ha ), stover yield (6.42 t ha -1 ), biological yield (11.08 t ha -1 ) and highest harvest index (42.06%). Results also revealed that different levels of irrigation and foliar application of boron had no significant effect on concentration of N, P and S but significant effect was found in terms of concentration of K and B both in grain and straw. Combined effect of irrigation and foliar application of boron, I 1 B gave highest K concentration (0.855%) in grain but I 1 B 2 3 -1 gave highest K concentration (1.63) in straw. Again, I gave highest B concentration both grain and straw (14.80 and 20.10 μg g respectively). The Overall Results sugest that B in the form of H along with to irrigations at 18 and 55 DAS of can be advised to apply for getting maximum yield of BARIGOM 26 under the agro climatic conditions of SAU DEPARTMENT OF AGRICULTURAL CHEMISTRY FACULTY OF AGRICULTURE SHER-E-BANGLA AGRICULTURAL UNIVERSITY DHAKA-1207 2016-01-01T00:00:00Z http://localhost:8080/handle/123456789/2276 EFFECT OF GA AND NITROGEN ON GROWTH, YIELD AND PROTEIN CONTENT OF MUNGBEAN ALAM, MD. MAHBUBUL An experiment was conducted at research field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from March to June, 2016 to find out the effect of GA and nitrogen (N) on growth, yield and protein content of mungbean. The experiment consisted of two factors: Factor A: Three levels of GA 3 viz.G 0 : control (no GA 3 ); G 1 : 50 ppm GA ii 3 ; G 2 : 100 ppm GA and Factor B: Four levels of nitrogen (N). viz.N 0 : Control (no urea), N 1 3 : 22 kg urea ha -1 : 44 kg urea ha -1 , N 3 : 66 kg urea ha -1 . There were 12 treatment combinations. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different growth and yield contributing characters and yield were recorded to find out the optimum levels of GA 3 , N 2 and nitrogen (N) on mungbean production. Due to GA application maximum number of pods plant -1 (107.52), seeds pod -1 (9.97), chlorophyll content (52.75 %), seed yield (2.16 t/ha), stover yield (1.05 t/ha), nitrogen content (4.11 %) and protein content (25.72 %) were recorded from G 1 (50 ppm GA ) treatment while minimum from G (control) treatment. Due to nitrogen application maximum number of pods plant -1 0 (108.94), seeds pod -1 (10.14), 1000 seed weight (47.22 g), seed yield (2.16 t/ha), stover yield (1.08 t/ha), nitrogen content (4.16 %), protein content (26.00 %) were observed from N 2 (44 kg urea ha -1 ) treatment while the minimum were observed from N (control) treatment. In the case of interaction effect maximum number of pods plant 0 -1 (132.27), seeds pod -1 (11.30), 1000 seed weight (47.92 g), seed yield (2.38 t/ha), stover yield (1.28 t/ha), nitrogen content (4.20 %) and protein content (26.25 %) were recorded from G 1 N 2 (50 ppm GA with 44 kg urea ha -1 ) treatment combination while the minimum from G 0 N 0 3 (control) treatment combination. The overall results suggest that 50 ppm GA 3 along with 44 kg urea ha can be applied to obtain optimum mungbean yield, nitrogen and protein contents under the agro-climatic condition of SAU.

Total twenty samples were collected from each of the rivers to analyze some physico-chemical properties which are available within the research facility of the department of Agricultural Chemistry in Sher-e-Bangla Agricultural University. The analytical parameters were -Color, Odor, pH, Total Dissolved Solids (TDS), Salinity, Sodium (Na), Potassium (K), Calcium (Ca), Carbonate (CO3) and Bicarbonate (HCO3). The obtained results of the present study shows that most of the parameters were not exceed the maximum permissible limit for irrigation, livestock and aquaculture except Bicarbonate in both rivers. Bicarbonate was found the ranges of 31 to 91.5 mg/L, whereas the standard limit of Bicarbonate is 1.50 mg/L for irrigation. From the statistical point of view, though there were some parameters showed the positive correlation but most of the parameters were negatively correlated with other parameters. From the findings, we may conclude that the quality of rivers water was not so serious problematic for agriculture.
