The experiment was conducted in spilt plot Design with 3 replications. The different levels of vermicompost 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 increased with the increasing vermicompost levels except water percentage. The variety „BARI Alu-28‟ produced maximum yield (28.89 t ha 4 -1 ) whereas, „BARI TPS-1‟ showed minimum yield (22.95 t ha -1 ) irrespective of vermicompost levels and other growth, yield and processing characters also influenced by the different varieties. The results also revealed that the yield of potato varieties were increased with increasing vermicompost levels. „BARI Alu-28‟ cultivated with vermicompost 6 t ha performed the best results and the same variety with 4 t ha -1 also showed the statistically similar results in terms of growth, most of the yield and quality parameters. Among the 16 treatment combination maximum tuber weight (57.18 g) was produced in V and the variety Lady Rosetta produced highest yield (33.86 t ha -1 ), highest marketable yield (28.78 t ha -1 ) and also produced maximum seed tuber (25.40 t ha ) when cultivated with 6 t ha -1 vermicompost. Incase of dry matter, reducing sugar and starch content, Lady Rosetta showed the best performance compared to those other varieties when 6 t ha -1 vermicompost was applied. 3 -1 2 2 - (2 t ha Vm -1 4, - 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 IN AGRONOMY SEMESTER: JANUARY-JUNE, 2015 Mon, 01 Jun 2015 00:00:00 GMT http://localhost:8080/handle/123456789/2456 2015-06-01T00:00:00Z http://localhost:8080/handle/123456789/2455 EVALUATION OF HERBICIDAL EFFICACY AND RESIDUAL ACTIVITY ON DIRECT SEEDED BORO RICE KAES, IMRUL An experiment was conducted at the Agronomy field laboratory, Sher-e-Bangla Agricultural University, Dhaka, from November 2014 to April 2015 to evaluate the different herbicidal efficacy on weed control and growth & yield of boro rice cv. BRRI dhan50. The experiment comprised nine treatments viz. Acetachlor + Bensulfuran (Premix) @ 750 g ha -1 , Pyrazosulfuran-ethyl @ 150 g ha -1 , Bispyribac Sodium @ 150 g ha , Pretilachlor @ 1 L ha -1 , Pretilachlor+ Triasulfuran@ (1 L + 10 g) ha -1 , Propyrisulfuran + Propanil @ (0.5 L + 1 kg) ha -1 , Propyrisulfuran + Propanil@ (0.38 L + 1.5 kg) ha , Two hand weeding (20 and 40 DAS) and Weedy check.The experiment was laid out in randomized complete block design (RCBD) with three replications. Sixteen weed species belonging to seven families were observed in the experimental field. Weed population, weed dry weight and weed control efficiency were significantly influenced by herbicidal treatments. The highest weed population and dry weight were observed in unweededcontrol condition compared to other treatments. Application of Propyrisulfuran + Propanil (0.38 L + 1.5 kg) ha -1 showed the best performance to control all kind of weeds found in the field and its residual activity remained upto 45 days.Yield contributing characters and yield of BRRI dhan50 was significantly influenced by weed control treatments. The highest number of effective tillers hill -1 , grains panicle , 1000grain weight, grain yield, straw yield and harvest index were obtained from the application of Propyrisulfuran + Propanil (0.38 L + 1.5 kg) ha -1 . Weed control had pronounced influence on yield (5.50 t ha -1 ) of BRRI dhan50 and 46.55% yield was lost in unweeded control condition. It can be concluded that application of Propyrisulfuran + Propanil (0.38 L + 1.5 kg) ha -1 may be used for the best performance of BRRI dhan50. However, in practical point of view the application of Propyrisulfuran+ Propanil (0.5 L + 1 kg) ha -1 may consider for producing second highest yield of BRRI dhan50. -1 -1 -1 AThesis Submitted to the Dept. of Agronomy, Sher-e-Bangla Agricultural University, Dhaka, in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE IN AGRONOMY SEMESTER: JANUARY-JUNE, 2015 Mon, 01 Jun 2015 00:00:00 GMT http://localhost:8080/handle/123456789/2455 2015-06-01T00:00:00Z http://localhost:8080/handle/123456789/2454 EFFECT OF NITROGEN LEVELS ON GROWTH, YIELD AND SEED QUALITY OF WHEAT AKTER, MAHBUBA A field experiment was conducted at the Research Field and Agronomy Laboratory of Shere-Bangla Agricultural University, Dhaka 1207 during the period from November, 2014 to March, 2015 to evaluate the effect of nitrogen levels on growth, yield and seed quality of wheat. The experiment comprised of five nitrogen levels viz. (i) N = Control (no nitrogen), (ii) N 1 = 25% less nitrogen from the recommended dose, (iii) N 2 0 = Recommended dose of nitrogen, (iv) N 3 = 25% higher nitrogen than recommended dose, (v) N = 50% higher nitrogen than recommended dose and four wheat varieties viz. (i) V 1 4 = BARI gom 21, (ii) V = BARI gom 23 (iii) V 3 = BARI gom 24 and (iv) V = BARI gom 27. The experiment was laid out in a split plot design with three replications. Data were collected on different parameters of growth, yield attributes, yield and seed quality of wheat. Results revealed that N 4 (25% higher nitrogen than recommended dose) gave the highest grain yield (3.41 t ha-1) which was statistically at par with N (recommended dose of nitrogen) (3.29 t ha-1). This might be attributed to highest number of spikes m 2 -2 (194.46), spike length (15.61 cm), number of spikelets spike -1 (20.91), number of grains spike -1 (48.17) and 1000-grain weight (47.08 g). Out of 4 varieties V 3 (BARI gom 24) showed highest grain yield (3.02 t ha ) which was statistically similar with V 4 (BARI gom 27) (2.89 t ha -1 -1 ). The variety BARI gom 27 (V ) also showed higher number of grains spike -1 (46.65) and 1000-grain weight (49.53 g). In respect of seed quality, N (recommended dose) showed higher quality of seed which was statistically similar to N 2 (25% higher nitrogen dose than recommended) because this nitrogen dose gave highest germination percentage (96.67 %), vigor index (10.34), shoot length (19.94cm) and dry weight seedling 3 -1 (0.19 g). In the case of variety, V (BARI gom 27) showed the higher seed quality attributes of germination percentage (95.20%), vigor index (10.52) shoot length (20.51cm) and dry weight seedling -1 (0.18 g). Regarding the interaction of nitrogen doses and varieties, N 2 V 3 , N 2 V 4 and N 3 V were shown best in producing quality seeds. From the above results it was concluded that the recommended dose and 25% higher nitrogen than recommended dose with BARI gom 27 shows better for producing higher yield and quality seed. 4 4 2 3 4 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 IN AGRONOMY SEMESTER: JANUARY-JUNE, 2015 Mon, 01 Jun 2015 00:00:00 GMT http://localhost:8080/handle/123456789/2454 2015-06-01T00:00:00Z http://localhost:8080/handle/123456789/2453 EFFECT OF SEEDLINGS PER HILL ON YIELD AND YIELD COMPONENTS OF HYBRID AND INBRED RICE VARIETIES JOHORA, MOSA. FIMATUZ The experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period of July to November 2014 to find out the effect of seedlings hill -1 on yield and yield components of hybrid and inbred rice varieties. The experiment comprised of two factors. Factor A: Rice variety (2) designated as V 1 : Hybrid (Chamak); V 2 : Inbred (BRRI dhan62) and Factor B: Number of seedlings hill -1 (5 levels) named as S 1 : 1 seedling hill -1 , S 2 : 2 seedlings hill : 3 seedlings hill -1 , S 4 : 4 seedlings hill -1 and S 5 : 5 seedlings hill -1 . The experiment was laid out in split-plot design with three replications. Experimental results showed that varieties had the significant effects on plant height, number of tillers hill , dry weight hill -1 , total tillers hill -1 , panicle length, number of filled and unfilled grains per panicle, 1000 seed weight, grain yield, straw yield and harvest index. The highest grain yield (4.06 t ha -1 ) was observed from Chamak (hybrid) while the BRRI dhan62 (Inbred) gave the lowest grain yield (3.04 t ha -1 -1 ). The highest straw yield was observed from V 1 (4.67 t ha -1 ) and the lower straw yield was recorded from V 2 (4.21 t ha ). Number of seedlings hill -1 also significantly affected all the parameters under study. The maximum number of effective tillers hill -1 was found from S 2 (12.20), whereas the minimum number of effective tillers hill -1 from S 5 (10.27). The highest grain yield was found from S 2 (4.10 t ha -1 ), whereas the lowest grain yield from S 5 -1 (2.93 t ha ). The highest straw yield was found from S 2 (4.80 t ha -1 ), whereas the lowest straw yield from S 5 (4.14 t ha -1 ) which was statistically similar to S 4 (4.21 t ha ). In case of interaction effect of varieties and number of seedlings hill -1 , the highest grain yield was recorded from the combination of V 1 S 2 (4.74 t ha -1 ) and the lowest grain yield was found from V 2 S 5 (2.55 t ha -1 ) which was statistically similar with V 2 (3.79 t ha -1 ). From the above results it was appeared that Hybrid (Chamak) variety provided best yield with 2 seedlings per hill . -1 -1 S 3 -1 -1 , S 3 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 SEMESTER: JANUARY-JUNE, 2015 Mon, 01 Jun 2015 00:00:00 GMT http://localhost:8080/handle/123456789/2453 2015-06-01T00:00:00Z
