Item EFFECTS OF ARSENIC ON GROWTH, YIELD AND NUTRIENTS CONTENT OF BRRI dhan29 AND Binadhan-8(DEPT. OF AGRICULTURAL CHEMISTRY, 2016) PAUL, BILASH CHANDRAThe experiment was conducted in the net house and the Laboratory of Agro-Environmental Chemistry laboratory of the Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University, Dhaka-1207 and Department of Agricultural Chemistry, BAU during the Boro season (December-June) of the year 2014-15 to evaluate the effects of arsenic on growth, yield and nutrients content of two different Boro rice cultivars. 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.Item INFLUENCE OF IRRIGATION AND FOLIAR APPLICATION OF BORON FERTILIZER ON GROWTH, YIELD AND NUTRIENTS CONTENT OF BARI GOM 26(DEPT. OF AGRICULTURAL CHEMISTRY, 2016) MONDOL, MD. RABIUL ISLAMAn 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 SAUItem EFFECT OF GA AND NITROGEN ON GROWTH, YIELD AND PROTEIN CONTENT OF MUNGBEAN(DEPT.

MAHBUBULAn 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.Item ASSESSMENT OF PHYSICO-CHEMICAL PROPERTIES OF BURIGANGA AND TURAG RIVER WATER(DEPT. OF AGRICULTURAL CHEMISTRY, 2016) BAGCHI, AMITThis investigation was conducted to assess the physico-chemical properties of different point of Buriganga and Turag Rivers for agricultural purpose.

Result indicated that the lowest values of germination percentage, shoot length, root length and dry weight of two test species were in treatment P 6 and highest in P 1 treatment. Thus, ten selected vegetables in Bangladesh could be used to control associated crops. Therefore, these vegetables used in this study could be candidates for isolation and identify of phytotoxins to serve as weed inhibiting agents for sustainable crop production.Item ASSESSMENT OF PHYSICO-CHEMICAL PROPERTIES OF WATER OF THE RIVER SHITALAKSHYA AND BALU(DEPT. OF AGRICULTURAL CHEMISTRY, 2016) SUTRADHAR, CHANDANThis study was conducted to assess some physico-chemical properties of water collected from different point of Shitalakshya and Balu Rivers. Total forty samples were collected from the two rivers to analyze the physico-chemical properties such as Color, Odor, pH, Total Dissolved Solids (TDS), Salinity, Sodium (Na), Potassium (K), Calcium (Ca), Carbonate (CO 3 ) and Bicarbonate (HCO ). The results of the present study shows that most of the parameters were not exceed the maximum permissible limit except Bicarbonate. Bicarbonate was found the ranges of 61 to 91.5 mg/L, whereas the standard limit of Bicarbonate is 1.50 mg/L. So, it can be concluded that the water of Shitalakhya and Balu rivers are contaminated by the factories, waste materials, tanneries and it should be considered as a threat for the aquaculture, agricultural productions, fisheries, livestock, recreational activities and various industrial uses.Item ASSESSMENT OF PHYSICO-CHEMICAL PROPERTIES OF SOME LAKES AND PONDS WATER OF DHAKA METROPOLITAN CITY(DEPT. OF AGRICULTURAL CHEMISTRY, 2016) RAHMAN, MD. ZILLURThis study was carried out to determine some physico-chemical properties of different lakes and pond of metropolitan city, namely Curzon Hall, Dhanmondi, Hatirjheel and Sher-e-Bangla Agriculutral University campus, Dhaka. Ten samples were collected from the each pond and lakes to analyze the physico-chemical properties such as Color, Odor, pH, Total Dissolved Solids (TDS), Salinity, Sodium (Na), Potassium (K), Calcium (Ca), Carbonate (CO3) and Bicarbonate (HCO3). The odor of lakes water was slightly bad and the color was light grey to slightly black. The results of the present study shows that except pH, K and HCO3, other measured parameters did not exceed the maximum permissible limit. The pH exceeded (8.22) the standard limit (>8) for other three lakes except Hatirjheel lake. The K content exceeded the acceptable limit (<5mg/L) except SAU campus pond. And Bicarbonate was found within ranges of 244 to 400mg/L for all the pond and lakes, whereas the standard limit of Bicarbonate is 1.50mg/L. From the statistical point of view, most of time, pH and Bicarbonate showed negative correlation with other parameters. So, it can be concluded that without proper analysis of the water quality of different lakes and pond of Dhaka city should not use for drinking purposes, agricultural productions, fisheries, livestocks, recreational activities and various industrial uses.Item EFFECTS OF BORON AND ZINC ON THE GROWTH, YIELD AND NUTRIENTS CONTENT OF LENTIL(Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University.

Dhaka, 2016-06) MAMUN, MD. SHAMIM ALAn experiment was conducted at the net house and the Laboratory of Agro-Environmental Chemistry lab of the Department of Agricultural Chemistry, Sher-e-[Iangla Agricultural University. Dhaka - 1207 during the Soro season (I)ecember-Junc) of the year 2014-15 to study the reclamation of salinity by potassium fertilization methods. The experiment was completed using 4 salinity levels (0.3.6 and 9 dS m4) and 5 potassium fertilization processes (Ko= no foliar application ofK , K.s = 0.5 mMK foliar application of K. K1 = 1 mMK foliar application of K, Ki.s = 1.5 mMK foliar application ofK, K2 = 2 mMK foliar application of K and 2/3 soil application oftotal Mo? fertilizer in all the treatments). BRRI dhan29 was used as variety. Salinity adversely affected all the growth and yield parameters of BRRI dhan29. Like most of the parameters, the highest 1000-grain weight (21.85 g) was recorded in 0 dS m 1, while highest grain yield (5.375 ton ha4) was recorded in control salinity treatment. The maximum grain yield (3.892 ton ha4) and straw yield (5.532 ton ha4) were recorded from Ko.s and K0 respectively whereas the minimum grain yield (3.357 ton ha4) and straw yield (4.566 ton ha') were found from Ki.s and Kiotreatnient respectively. Use of potassium alleviated the adverse effects of high salinity on rice plant. Most of the growth and yield attributes varied significantly due to the different fertilization processes of potassium. Among them 0.5 mMK. 1.5 mMK and 2.0 mMk foliar spray, 2/3 rd soil application of total Mo? fertilizer gave better perthrmances with the salinity levels of 3, 6. and 9 dS m'. S0K05 gave the highest grain yield (6.187 ton ha4) while ScK1 .s gave the lowest grain yield (1.157 ton haS') .Na content in straw and grain increased with the increase in the salinity level while K content decreased. In this case also, foliar spray along with soil application of Mo? fertilizer performed better while treated with salinity compared to sole foliar spray or soil applications.Item EVALUATION OF THE REPELLENT EFFECTS OF DIFFERENT BOTANICAL EXTRACTS ON TOMATO INSECTS(Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University.
