The experiment consisted of two factors; viz. factor A: Three rice varieties namely V]= Kataribhog, V2 = BRRI dhan41 and V3 = BRRI dhan34 and factor B: fertilizer doses viz., Tl: Recommended doses ofNPKSZn, T2 = 800' recommended doses of NPKSZn + green manure 3.5 t ha", T3 = 60% recommended doses ofNPKSZn + green manure 7 t ha", T4' = 40% recommended doses of NPKSZn, Green Manure 10.5 t ha", T5 = 20% recommended doses of NPKSZn +Green Manure 14 t ha" and T6 = Green Manure 17.5 t ha-I were used for the present study. The experiment was laid out in a split-plot design with three replicanons, 1n case of variety green manure and chemical fertilizer significantly affected all characters except dry matter content hiIJ-t at 15 DAT. Similarly, all traits were also affected significantly due to the effect of fertilizer management, the treatment 1'2 (80% recommended doses of NPKSZn + green manure 3.5 t ha") showed outstanding performance for getting the better growth and higher yield compared fo those of other treatments. Most of the studied traits were also influenced significantly due to the effect of interaction of variety and fertilizer management wbere the growth and yield showed significant variation. The variety BRR! dhan34 treated with SOOIo recommended doses ofNPKSZn + green manure 3.5 t ha-l (V3T2) as well as the highest number of tillers 'hill·l (13.93, 19.78, 21.33, 21.00, 20.44 and 19.44 at 15, 30, 45, 60, 75 DAT and at harvest, respectively), maximum effective tillers hiU-1 (15.50), the highest number of grains panicle" (252.10), maximum filled grains panicle" (212.8) and highest yield of grain (2.67 t ha") were recorded. The highest (8.85%) and lowest (8.52%) protein content in rice grain was observed in Kataribhog (VI) and BRRI dhan34 (V3), respectively. The highest protein content in rice grain (9.42%) was observed in V3T6 and the lowest protein content in rice grain (7.76%) 'was found in V3T4. The highest (77.63%) and lowest (77.12%) carbohydrate content in rice grain was observed in BRRI dhan34 (V3) and BRRI dhan52 (V2), respectively. The highest carbohydrate content in rice grain (79.24%) was observed in VITt and the lowest (75.00%) was found in VIT4. Considering the above fact, 80% ' recommended dose of NPKSZn + green manure 3.5 t ha'icould be considered the best fertilizer management practice for optimizing the production of aromatic rice during aman season.

The experiment was laid out on Randomized Completely Block Design (RCBD) , with three replications, There were four mustard oil cake (MOC) fertilizer levels, viz" Mr=no mustard oil cake, M2=25 kg ha", M3=50 kg ha-l, M4=75 kg ha" and three time of application viz., Tj=Basal dose, T2=20 DAT, and T3=35 DAT, Mustard oil cake was top dressed in three equal splits at 10, 35 and 55 DAT, Results indicated that the effect of mustard oil cake showed significant variation in respect of all growth, yield contributing characters and yield, At harvest, highest plant height (81.66cm), tillers hill-] (21.55), effective tillers hill-] (14.22), panicle Jength (21,:87cm), filled grains panicle" (132.1), 1000 grain Weight (29.35 g), grain yield ( 8.2 t ha-\ straw yield (5.16 tha") was obtained from the application of MOC, Onthe other hand, highest plant height (81.67cm), tillers hill-] (21.42), effective tillers hill-l (14,58), panicle length (22.84cm), filled grains panicle" (132,24), 1000 grain weight (29.35 g), grain yield ( 7.6 t ha"), straw yield ( 5.'] 5t ha") was obtained from the time of application .. Mustard 011 cake @ 75 kg gave the highest grain yield (7.6 t ha"). Interaction effect showed that application of MOC @75 kg application in 75 days after application gave the highest (9.9 t ha") grain yield. Therefore, application of MOC .® 75 kg ha-1 at 35 DAT appears to be the best package for BRRl dhan67 produced higher yield, A Thesis Submitted to the Department of Soil Science, Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka in partial fulfil1ment of the requirement for the degree of MASTER OF SCIENCE (MS) IN SOIL SCIENCE 2020-01-01T00:00:00Z http://localhost:8080/handle/123456789/4484 EFFECT OF NITROGEN ON THE VARIETAL PERFORMANCE ON CORIANDER (Coriandrum sativum L.) GHOS, NITAI CHANDRA Coriander is one of the most important and major spices in Bangladesh as well as world. A field experiment was conducted at the farm of Sher- E- Bangla Agricultural University, Dhaka from November 2018 to February 2019 to examine the effect of nitrogen on the varietal performance on coriander. The experiment consisted of two variety viz. V = BARI Dhonia-1 and V = BARI Dhonia-2 and six levels of nitrogen viz. 0, 20, 40, 60, 80 and 100 kg ha -1 2 . The experiment was laid out in Randomized Complete Block Design (factorial) with three replications. There were 12 treatment combinations in all. The BARI Dhonia-2 produced maximum number of branches per plant, number of umbel per plant, number of seed per plant, 1000 seed weight, seed yield per plot. The highest yield (1432.40 kg ha -1 ) was obtained from BARI Dhonia-2. The tallest plant and maximum number of leaves plant -1 were recorded at 60 kg N ha -1 followed by 80 kg N ha at different growth stages. Application of 60 kg N ha -1 gave the maximum branches plant , umbellates umbel -1 , seed plant -1 , 1000 seed weight, seed yield plot -1 and seed yield (1691.65 kg ha -1 ). Application of 60 kg N ha -1 coupled with BARI Dhonia-2 gave the maximum seed yield of (1699.98 kg ha -1 ). The highest concentration of N and K in post harvest soil was recorded in the treatment combination of BARI Dhonia-2 with application of60 kg N ha -1 .

MONIRUZZAMAN A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka 1207 during November 2018 to February 2019 to study the effect of phosphorus and sulphur on the growth and yield of mustard (Bari sarisa-14). The experimental soil was clay loam in texture having pH of 5.7. The experiment included three levels of phosphorus viz. 0, 28, and 36 kg P ha and three levels of sulphur viz., 0, 16, and 20 kg S ha -1 . The experiment was laid out in a Randomized Complete Block Design with three replications. Phosphorus showed significant effect on yield and yield attributes of mustard. Application of phosphorus (P 3 @36 kg ha -1 ) produced the highest seed yield, plant height, number of primary branches plant -1 , number of siliqua plant and 1000-seed weight. Sulphur fertilizer also had significant effect on yield and yield attributes of mustard. Application of sulphur @ 20 kg ha produced the highest number of primary branches plant -1 , number of siliqua plant but in all the cases relatively, the lower response was found from the control treatment. Phosphorus in combination with sulphur showed significant effect on yield and yield attributes of mustard. Plant height, no. of siliqua plant -1 , siliqua length, no. of seed siliqua -1 , weight of 1000 seed (g), seed yield was found the highest in the treatment combination P 3 S 3 . The addition of P and S not only increased the yield but also protect the soil from total exhaustion of nutrients.
