Dhaka-1207 during the June 2018 to December 2018 to have a comparative study on ten modern rice varieties in Aman season in relation to their growth behavior, leaf chlorophyll content and yield. The experiment consisted of 10 Aman rice varieties namely, BRRI dhan40, BRRI dhan41, BRRI dhan44, BRRI dhan46, BRRI dhan53, BRRI dhan71, BRRI dhan75, BRRI dhan80, BRRI dhan87 and BRRI dhan90. The experimental plots were laid out in randomized complete block design (RCBD) with three replications. Ten (10) genotypes were distributed to each plot of 4 m x 2.5 m size within each block randomly. The highest no. of filled grain per hill was obtained from the verity BRRI dhan80 and the lowest no. of filled grain per hill from BRRI dhan53. The highest no. of unfilled grain per hill was obtained from the verity BRRI dhan71 and the lowest no. of unfilled grain per hill from BRRI dhan87. The maximum days to maturity (134.25) were recorded from BRRI dhan44, while the minimum days to maturity (100.50) was recorded from BRRI dhan41. The maximum number effective tiller hill -1 (16.75) was recorded from BRRI dhan53, whereas the minimum number of effective tillers hill -1 (12.05) was recorded from BRRI dhan44. The maximum number of filled grains panicle -1 (89.90) were recorded from BRRI dhan53, whereas the minimum number of filled grains panicle (75.80) was recorded from BRRI dhan44. The highest weight of 1000-grains (25.71 g) was recorded from BRRI dhan53, while the lowest weight of 1000-grains (19.45 g) was obtained from BRRI dhan75. The highest grain yield (5.45 t ha ) was recorded from BRRI dhan53, whereas the lowest grain yield (3.49 t ha ) was provided by from BRRI dhan44. The highest straw yield (7.97 t ha ) was recorded from BRRI dhan53, whereas the lowest straw yield (6.58 t ha ) was given by BRRI dhan44. So, BRRI dhan53 was superior for Aman season in consideration of yield attributes and yield. -1 -1 -1 -1 -1 A Thesis Submitted to the Faculty of Agricultural Botany Sher-e-Bangla Agricultural University, Dhaka in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE (MS) IN AGRICUTURAL BOTANY SEMESTER: JULY-DECEMBER, 2018 2018-12-01T00:00:00Z http://localhost:8080/handle/123456789/4071 PERFORMANCE OF HYBRID AND MODERN INBRED RICE VARIETIES UNDER AEROBIC CONDITION LUCKY, DILRUBA AKTER The field experiment was conducted at the Research Farm of Sher-e-Bangla Agricultural University, Dhaka during November, 2017 to June, 2018 to study the performance of hybrid and modern rice varieties under aerobic condition.

The experiment consisted of two factors, factor A-plant growing structures, viz., S 1 = Plastic pot, S = Earthen pot and factor B-six different plant growing medium viz. M 0 2 =Soil 100%(w\w) with Recommended Dose of Inorganic Fertilizers (RDIF)/ (control), M 1 =Soil 80% (w\w) +20% Cow dung (w\w) along with RDIF, M =Soil 60% (w\w) + Cow dung 40% (w\w) along with RDIF, M =Soil 90% (w\w) +10% Vermicompost (w\w) along with RDIF, M 4 3 =Soil 80% (w\w) +20% Vermicompost (w\w) along with RDIF and M =Soil 70% (w\w) +20%Cowdung (w\w) +10% Vermicompost (w\w) along with RIDF. The factorial experiment was laid out in a Completely Randomized Design (CRD) with four replications. The experimental result such as morphological character and yield of brinjal significantly influenced by different plant growing structures and plant growing media and their combination. As for plant growing structures, the plastic pot (S ) gave the highest plant height, number of leaves per plant, branch per plant, flowers per cluster, flowers per plant, fruit length, fruit diameter, fruits per plant. The highest yield of fruits per plant (740.16 g) was obtained from plastic pot(S 1 ) and Soil 70%(w\w) +20% cow dung(w\w) +10% vermicompost(w\w) along with RDIF marked as S 1 M . The lowest yield of fruits per plant (144.72 g) was obtained from earthen pot and Soil 100% (w\w) along with RDIF marked as S 5 2 M . Considering the stated findings, it may be concluded that BARI Begun-8 planted in plastic pot and Soil 70% (w\w) +20% Cow dung (w\w) +10% Vermicompost (w\w) along with RDIF would be beneficial for increasing the yield of brinjal during kharif season in the rooftop garden under the climatic conditions of SAU. 0 2 5 2 A Thesis submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka-1207in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE (MS) IN AGRICULTURAL BOTANY SEMESTER: JULY- DECEMBER, 2018 2018-12-01T00:00:00Z http://localhost:8080/handle/123456789/4069 TILLERING PATTERN, LEAF CHARACTERISTICS AND YIELD OF TEN MODERN RICE VARIETIES IN AMAN SEASON HOWLADER, MD RUBEL The study was conducted at the experimental farm of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar. Dhaka-1207 during the period from June 2018 to December 2018 to have a comparative study on ten modern rice varieties in Aman season in relation to their growth behaviour, leaf chlorophyll content and yield. The experiment consisted of 10 Aman rice genotypes (BRRI hybrid 4, BRRI dhan32, BRRI dhan33, BRRI dhan39, BRRI dhan49, BRRI dhan52, BRRI dhan54, BRRI dhan56, BRRI dhan57, BRRI dhan62). The experimental plots were laid out in randomized complete block design (RCBD). The field was divided into three blocks; representing three replications. Row to row and plant to plant distances were 25cm and 20cm respectively. Ten (10) genotypes were distributed to each plot of 4 m x 2.5 m size within each block randomly. The highest no. of filled grain per hill was obtained from the variety BRRI dhan56 and the lowest no. of filled grain per hill from BRRI dhan49. The highest no. of unfilled grain per hill was obtained from the variety BRRI dhan52 and the lowest no. of unfilled grain per hill from BRRI dhan49. The highest 1000 seed weight per hill was obtained from the variety BRRI hybrid 4 (28.16 g) which is statistically similar with BRRI hybrid 4 and the lowest 1000 seed weight per hill from BRRI dhan54. The highest grain yield per hill was obtained from the variety BRRI dhan33 (52.93 g) and the lowest grain yield per hill from BRRI dhan56 (29.9 g). The highest no. of unfilled grain per hill was obtained from the variety BRRI dhan54 (30.4 g) and the lowest no. of unfilled grain per hill from BRRI dhan57 (18.5 g). The highest biological yield per hill was obtained from the variety BRRI dhan32 (94.1 g). So, the variety BRRI dhan33 was better for higher yield and quality among the test modern Aman rice varieties.
