STUDIES ON THE EFFECTIVENESS OF LOW COST SOLAR TUNNEL DRIER OVER TRADITIONAL SUN DRYING OF PRAWN, Macrobrachium lamarrei IN THE LABORATORY Fatema, K.; Ahmed, A. T. A.; Khaleque, M. A.; Begum, M. Laboratory experiment was carried out to compare the effectiveness of the new Low Cost Solar Tunnel Drying (LCSTD) technique with the Traditional Sun Drying (TSD) method of the Prawn, Macrobruchium lumarrci. [loth salted and unsalted Prawn (M. lamarrei) required 4 hours for drying in LCSTD, while in sun drying it required 6 hours, During the experimental period the inside drying temperature and percentage of relative humidity varied from 4:1 to solie and 35 to 50%, respectively, whereas outside drying temperature and percentage of relative humidity varied from 29 to .'8"C and 50 to 78%. respectively. Solar tunnel dried unsalted sample contained on an average of 14.65% moisture, 61.58% protein. :1.4'7" fat and 17.23% ash whereas sun dried unsalted sample contained 20.5')1. moisture, 5~% protein. 3.1'if, fat and 15.5% ash.The rate of drying was greater in the Low Cost Solar Tunnel Drier (LCSTD), which effectively controlled the fly larva infestation during drying. The low cost solar tunnel drier produced superior quality dry prawn under hygienic conditions.

PERFORMANCE OF VARIETY AND PLANTING MATERIALS ON THE YIELD AND YIELD ATTRIBUTING CHARACTERS OF SWEET POTATO Rashied, M. H.; AI- Mamun, M. N. H.; Islam, A. B. M. S.; Rahmani, M. M.; Jahangir, N. M. he present experiment was conducted at the Horticulture Farm, Bangladesh Agricultural University, Mymensingh during the period from December 2001 to May 2002 to study on the performance of variety and planting materials on the yield of sweet potato. There were five sweet potato varieties viz.,Tripti, Kamalasunduri, Daulatpuri, BARI sweet potato-a and BARI sweet potato-5 and three portions of vine cutting used as planting materials, viz .. tip, middle and basal portion. TIle experiment was laid out in RCBD with three replications. Growth habit, yield contributing characters and yield of sweet potato were found to vary significantly from one variety to other. The highest yield of tuberous roots was found in the variety Tripti (33.90 Ifha) and the lowest yield was obtained from the variety Daulatpuri (21.60 Ifha).Vine parts used had significant influence on growth and yield of sweet potato. Planting of tip cuttings gave the highest yield (31.58 t/ha). The yield of tuberous roots (26.85 t/ha) were recorded as the lowest from basal cuttings. The combination of different varieties and planting materials exhibited significant variation in some yield components and yield of sweet potato. The combination of Tripti with tip cuttings produced the highest yield of tuberous roots (36.07 Ifha).

MERITS AND DEMERITS OF ECOLOGICAL AGRICULTURE AND MODE OF ITS ADOPTION IN BANGLADESH* Ali, M. S.; Karim, A. S. M. Z. he main purpose of stusdy was to discuss about the merits and demerits of ecological agriculture and to determine its mode of adoption in Bangladesh. Attempt was made to search internet. available books. journals and printed materials from different sources of home and abroad during the period from June 2004 to October 2008 and it was revealed that there was on going debate in favour of and against ecological agriculture as it has many merits and demerits. For determining the mode of adoption of ecological agriculture in Bangladesh. data were collected from a sample of 144 ecological farmers drawn from a population of 478 ecological farmers of six Area Development Centers (ADCs) of Proshikha with the help of a pre-tested interview schedule during the period from February to August. 2006. Findings revealed that more th:1I1half (52.12 per rent) of the total lands of the respondent farmers were cultivated by the mixture of ecological and chemical practices compared to 47.66% of the total land of the farmers were cultivated by absolute use of ecological agricultural practices and only 0.22% of the total land of the fanners were cultivated by absolute chemical inputs.

IDENTIFICATION OF SELF-INCOMPATIBLE LINE FROM AVAILABLE GERMPLASMS OF Brassica napus Mahmud, F.; Rasuf, M. G. Self-incompatibility mechanism in 22 local germplasm of Brassica napus genotypes was investigated through seed set analysis and pollen tube growth behavior. Based on the seed set ratio. levels of self- incompatibility varied from 0.0 to 93.33 percent. The entries Nap 205, Nap 248 and Nap 2037 showed low level of self-compatibility. The genotypes Nap 0130, Nap 2013, Nap 9901. Nap 9904 and Nap 94006 showed intermediate level of self-incompatibility whereas the genotypes Nap 2001 and BARI Sarisha-l J were almost self-incompatible. Based on the number of pollen tubes in the style, the genotypes Nap 108. Nap 179. Nap 206, Nap 2012, Nap 2022, Nap 2057. Nap 2066, Nap 9905 and Nap 9908 were grouped as self-compatible: Nap 0130. Nap 2013. Nap 9901, Nap 9904. Nap 94006, BAR I Sharisha-? and BARI Sharisha-S as intermediate. Rest of the genotypes Nap 205. Nap 248, Nap 2001, Nap 2037 and BARI Sharisha-l J were classed as self-incompatible. Both the methods provide more or less similar results. Five genotypes. namely Nap 205. Nap 248. Nap 2001, Nap 2037 and BARI Sharisha-13 showed high level of self-incompatibility along with success on bud pollination for producing Sllines.
