Ago Ecological Zone (AEZ-28). To find out the efficacy of vermicompost (VC) and conventional compost (CC) on cauliflower (Bans/ca oleracea var. botiytis) yield, uptake. optimum rate or vermicompost and conventional compost for cauliflower cultivation. Minimize the use of chemical fertilizer in presence of vermicompost or conventional compost. The experiment was laid out in RCRD design with twelve treatments replicated three times. The treatments were: T,= 100% Recommended Dose of Chemical Fertilizer (RDCF),T 2 = 80% RDCF.T 60% RDCF,T4= 100% RDCF+ VC ® 1.5 t h&',T 80% RDCF+ VC @3 t hi', T 6= 60% RDCF+ VC @6 hi',T VC @ 6t haS'. fr 100% RDCF+ CC @ 1.51 ha",T 9 80 0/o RDCF+ CC @ RDCF+ CC @ 6 t hi', 111= CC @ 6 t ha",T,2 = Absolute control. The doses of 100% RDCF was 1` 51(6 S40 Zn5 B,kg hi'. The sources of vermicompost were cowdung and kitchen wastes (3:1) processed by epigeic earthworm Lisenia Jet/do. Different nutrient packages significantly influenced the yield and yield components of cauliflower. It was observed that 100% RDCF+ 1.5 t ha S ' vermicompost produced the highest curd yield (37.63 t ha 1 ) of cauliflower. This yield was statistically identical with 100% RDCF + 1.5 1 hi' conventional compost (34.67 t hi') and 80% RDCF + 3.0 t hi' vermicompost (34.07 t hi'). Vermicompost exhibited better performance than conventional compost alone or in combination with chemical fertilizer. The enhanced yield of cauliflower in this study can be partially explained by the elevated levels of NPKS contents in the vermicompost. It is suggested that vermicompost (1.5 t ha") + NPKSZnB (100%) is more flivorable for higher curd yield of cauliflower and suitable for soil environment but vermicompost (3 1 ha) + NPKSZnB (80%) can be more environmentally suitable. In this fertilizer package. 20% chemical fertilizer is reduced in presence of vermicompost. Use of vermicompost can play a vital role in minimizing the fertilizer crisis. ALL the treatments showed a negative balance for N and K and those for P and S was positive balance except the control treatment at Joydebpur. Residual effect of vermicompost showed increased plant available nuthents in post harvest soil; to improve and sustain soil health as well as to improve crop production; chemical fertilizer rate needs to be reduced.

Dhaka during November 2006 to March 2007 to :;udy thc ....eels of nitrogen and phosphorus on growth. yield and quality of capsiculfi in i; Randomi:;d Complete l3ock Design (RCBD) with three replications. The treatments were 4 kvels N50, Ntco & N10, ofN (0,30. iOU & 50 kg ha designated as respectively) and 3 levels of P (0, 30 & 60 kv ha designated as P. respectively). Days to flower bud emergence, days to f ir st flower opening, plant height flowering and at first harvest, number of branches at first flowering . length and breadth of fruit and number of fruits per plant increased significantly with increasing nitrogen doses up to 100 kg N h&'. Uowevcr, plant height at final harvest, number of branches at first and final harvest, average weight of fruit, yield, thickness of pericarp and dry matter content increased significantly up to 150 kg N haS' (N3 treatment). On the other hand, days to flower bud emergence, plant height at first flowering, number of branches at first harvest, average weight of fruit, yield, thickness of periearp and dry matter content increased significantly with increasing levels of Pup to the treatment P (30 kg P hi'), where as plant height and number of branches at final harvest, length of Capsicun, treatment p2 number fruits per plant enhanced significantly up to the (60 kg P hi'). Considering the combined effect of nitrogen and phosphorus, the maximum significant days to flower bud emergence, days to first flower opening, days to first fruit set and plant height at final harvest were obtained from NP2 (100 kg N + the other hand, maximum length of capsicwfl, breadth of Capsicwn, P30 & Poo, at first 60 kg P hi'). On number of fruits per pluni. average weight of fruit. yield and dry matter content were found in the treatment combination N3 P, (150 kg N 30 kg P hi') The highest N content (1.71%) was observed in N,o treatment. but the highest concentration of N was obtained with N,sPo treatment. [he highest 1' concentratiOn (0.035%) from 0.027 to 0.03 5%.

S. A. A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm. Dhaka during the period from December 2007 to March 2008 to study the role of sulphur and boron alone and combined on the growth, yield of BAR! wheat 22 (Sufee) (Triticurn aestivurn I..). The experiment included four levels of sulphur viz.. 0, 10.20 and 30 kg Sha' and four levels of boron viz., 0,0.5. 1 and 2kg B hi 1 . The experiment was laid out in a Randomized Complete Block Design with three replications. Sulphur showed significant effect on yield and yield attributes of wheat. Application of sulphur @ 30 kg ha' produced the highest seed yield, plant height, number of tillers planf', spike length, number of effective spikelets spike -'. 1000-seed weight, straw yield. In all the cases lower response was found from the control treatment. Boron fertilizer also had significant effect on yield and yield attributes of wheat. Application of boron 'd, 1 kg hi' gave the highest seed yield, plant height, number of tillers plani', spike length, number of effective spikelets spike -', 1000-seed weight, straw yield but in all cases the lower response was found from the control treatment. Sulphur @ 30 kg ha' was found statistically superior to all other treatments. Sulphur in combination with boron showed significant effect on yield and yield attributes of wheat. Sulphur @ 30 kg hi' and boron @ I kg hi' resulted the highest seed yield, plant height, straw yield, number of effective spikelets spike -].. 1000-seed weight and total uptake of S and B by wheat. On the other hand, in all the cases lower response was found from the control treatment. The addition of S and B not only increased the yield but also protect the soil from total exhaustion of nutrients.

M. The field experiment was conducted at Sher-e-Bangla Agricultural IJniversity Farm. Dhaka during the boro season from I November 2007 to 15 March 2008 to observe the performance of zinc and boron on the yield and yield contributing characters of BRRI dhan29. The experiment consists of three levels of zinc viz. 0. 2.5 and 5.0 kg ha 4 and three levels of boron viz. 0, I and 2 kg hi'. The experiment was laid out in factorial randomized complete block design with three replications. Application of Zn significantly influenced all the growth and yield contributing characters except plant height (cm), panicle length (cm) and sterile spikelets panicle 4 whereas boron fertilization significantly influenced all parameters except plant height (cm). panicle length (cm) and 1000 grain weight. Five kg Zn hi' and two kg B hi' Zn s x 13 2 influenced plant to produce the highest grain yield. The maximum yield 5.56 thi' was recorded for this combination effect. Integrated use of zinc and boron significantly influenced contents and uptake of zinc (Zn) and boron (B) in the grain and straw of BRRI dhan29. In all eases of contents and uptakes of Zn and B in both grain and straw as allècted by Zn and B fertilizations. Zn5 13 2 performed the highest results.
