  The present study was conducted for karyomorphological investigation in 15 lines of two species of Hordeum. All the lines showed a diploid chromosome number of 14. Differences were observed regarding chromosome length, total chromatin length (TCL), type etc. among the 15 entries. The longest (11.06 μm) chromosomes were observed in BTON-10 while the shortest (4.23 μm) in BEL-4 and BEL-36 of Hordeum vulgare. Extra large chromosomes were found in BEL-4 (1 pair) and BTON-10 (5 pairs) of H. vulgare. Large type chromosomes were found in BHV-105, BTON-10 and conquest of H. vulgare. Medium type and relatively short type chromosomes were absent in BEL-36, BHV-1 and BTON-10 of H. vulgare, respectively. More metacentric chromosomes (7 pairs) were found in BHV-1 of H. vulgare. Maximum chromatin length (70.21 μm) was also found in BTON-10 and minimum (40.96 μm) in BEL-36 of H. vulgare. Maximum (47.76%) and minimum (39.88%) total fractional percentage (TF %) were found in BHV-1 and API-19 of H. vulgare, respectively. Each line has a specific chromosomal morphology which might be responsible for the variations of Hordeum species.

  Twenty two garlic genotypes of local and exotic origin was trailed during the period from November 27, 2000 to March 31, 2001 at SRC Bogra. The results indicated that the germplasm differed significantly as to the different morphological attributes, yield and other desirable traits. The height of plants varied from 42. 50-67. 33 cm whereas, there was no difference as to the number of leaves/plant. Length and width of individual bulb differed from 2.40-3.20 and 2.10-2.71 cm, respectively. The number of cloves/bulb and individual bulb weight were also varied significantly. The entries showed variable degree of pungency. Per hectare yield (t) of garlic genotypes varied from 2.18-6.29, being lowest in GC003 and highest in GC007. Considering pungency as a positive trait of selection and yield potentiality also with other parameters, the lines GC002, GC006, GC007, GC010, GC011, GC016, GC017 and GC021 were found promising.

  The experiment was conducted to evaluate the performance of Aus rice (CV. BR 20) under variable management. The treatments consisted of three tillage (Viz. 1 tillage, 2 tillage and 4 tillage) and three cultural practices (Viz. 2 raking, 2 weeding and 2 raking + 2 weeding). The Aus rice increased yield both for more tillage and cultural practices. Significantly, the highest grain yield (2.92 t ha-1) was obtained from 4 tillage with 2 raking and 2 weeding at 15 and 30 days after sowing (DAS). Though the treatment, 4 tillage with 2 raking and 2 weeding gave the highest yield but the benefit cost ratio (BCR) was found to be low (1.08) in this treatment. One tillage and two raking (15 and 30 DAS) was economically profitable practice with grain yield of 2.51 t ha-1 which also gave gross return of TK. 21520 ha-1, net return TK. 8731 ha-1+ and BCR 1.68.

  An investigation was conducted to evaluate the surface water quality at Matrianga Upazilla under very remote areas of Khagrachrari Hill District of Bangladesh. The chemical analyses of water collected from canals included pH, EC, total cations (Ca, Mg, Na, K, Zn, Cu, Mn, Fe, As, P and B), Total anions (CO3 , HCO3 , SO4 , NO3 , C1), TDS, SAR, SSP, RSC and hardness (HT ). pH values (6.75-7.27) indicated that the waters were slightly T acidic to neutral. waters contained Ca, Mg, Na, K, HOC3 and C1 predominantly along with Zn, P and B in lesser amounts. Mn, Cu and As were found trace to very little amount. Fe and SO4 were found trace. TDS and SAR values indicated that all waters were 4 under ‘good’ and ‘permissible’ classes. SAR and EC categorized the waters as C1-S1. All waters were found under ‘soft’ class regarding hardness with ‘suitable’ RSC. Based on As, Fe, Mn, Zn, SO4 , NO3 and C1 all waters were within the ´safe’ limit for drinking except one sample for As.

  Winter dry season is mainly depends on irrigation. Because, the rainfall in this season is almost zero. At the end of this season, ground water mainly remains at about 10-12 meter depth. On the other hand, the crop then remains at booting to flowering stages. During this period, a huge number of cracks developed on the puddled field due to shortage of water. Consequently, the size and number of cracks depend on the irrigation interval, the intensity and duration of drought spell. The sizes of the cracks are range about 10-30 mm wide. Normally, the major cracks goes below puddled layer of 70-100 mm and almost all the cracks are interlinked and remain active through the growing season. Therefore, a major portion of the irrigation water lost through this cracks. Hence, a large area remains fallow due to proper management and shortage of irrigation water. Therefore, irrigation application efficiency to be increased in cracking soils by reducing seepage and drainage losses in paddies. As a result, it is important to develop irrigation scheduling of rice for cracking soils on the basis of crack size rather than estimating crop water requirements based on evapotranspiration (ET) demand.

  A study of cracking soils management was conducted in the wet soil bin with nine soil management practice treatments to investigate their impact on infiltration rate. The treatments were arranged in a randomized complete block design (RCB) with three replications. It is observed that the management of cracking soils, even at an early stage of crack initiation, has a great influence on infiltration rate. Among the management practices, the hand hoe operation was found to be better than trampling to reduce the cracks when the crack width was 10 mm. It is also observed that there is no influence of crack number on infiltration if a soil management practice is included with irrigation. The study reveals that with a soil management practice, the cracks reduced or were removed in a short period of time even though the cracks were 10 mm wide. In contrast, without soil management, cracks remained open for a long period even after ponding. By practicing soil management during irrigation, a large volume of water can be saved which my help to bring more area under irrigation particularly where there are limited water resources.

  Two experiments were conducted in the laboratory with leaves of one plant species (Blumea lacera Dc.) Shiyalmutra or Kukurshunga for studying their repellency and toxicity test against the lesser grain borer (Rhyzopertha dominica F.) and rice weevil (Sitophilus oryzae L.; Bastrychidae:Coleoptera) with the attempt for chemical investigation of each extract. In the first experiment petroleum ether extract of dried leaves (1, 2 and 3% by volume) were used on the adult beetle of lesser grain borer and rice weevil to evaluate their repellency for mortality/direct toxicity effects. Results for the two experiments indicated that 1, 2 and 3% petroleum ether extract of leave of Blumea lacera Dc. species had repellency as well as direct toxicity, while 3% showed strong repellency and toxicity effects among the other extracts on both lesser grain and rice weevil.

  Genetically Improved Farmed Tilapia (GIFT) is one of the most successful one of all exotic fish species in Bangladesh from the view of acceptance and prevalence in cultured water bodies. Manual separation of male and female tilapia is one of the methods for obtaining single sex. In Bangladesh, abundance of sex reversed GIFT male is very limited, therefore, the experiment was conducted to compare the yield of manually separated GIFT with others. Highest yield (5285.3±289.9 kg ha-1) and gross return (358343.7±23555.6 tk ha-1) were found from manually separated male GIFT, which was significantly different from others. Even manually separated female GIFT gave the better production than culture of both sexes together and of carps also.

  Nineteen-hybrid rice were evaluated in order to determine variability and genetic association for grain yield and its component characters. It was observed that all the tested characters had significant variation. The highest genotypic coefficient of variation was found in panicles per m2, followed by spikelets per panicles, grain yield, 1000-grain weight and flag leaf area. High heritability was observed for all the tested characters except grains per panicle and harvest index. High heritability and genetic advance was found in panicles per m2, spikelets per panicle and 1000-grain weight. Genotypic correlations were higher than the phenotypic correlations in most of the cases. Flag leaf area, days to maturity, grains per panicle, panicles per m2, , 1000-grain weight and harvest index showed highly significant positive correlation with grain yield both at genotypic and phenotypic levels. Path coefficient analysis of the study revealed that higher harvest index, adequate spikelets per panicle, days to maturity, more panicles per m2, and heavy grains had direct effect on grain yield. Grains per panicle had a positive but indirect effect on grain yield through spikelets per panicles and harvest index. Similar trends were also observed in panicle length through spikelets per panicle and in flag leaf area through harvest index.

  The study was made to evaluate the yield and quality of banana fruit affected by banana leaf and fruit beetle, Nodostoma viridipennis Mots, in an orchard and laboratory of Bangladesh Agricultural University, Mymensingh from October, 1997 to October, 1998. The beetle damaged the newly formed fruits in the hand having cluster of 13 bananas each showing 33-57 scars in seven days by 5 beetles, but the mean number of scars on fruits increased in second week after their emergence. The fruit size was also significantly reduced by caging insects after emergence and 15 days after emergence with more reduced size of the former fruit. The damage done by this beetle had tremendous influence on both quantity and quality of banana. Ripening duration of damaged fruits was prolonged significantly and fruit weight also reduced in comparison with beetle free fruits. The quality of infested banana with especial reference to skin colour and thickness, taste, smell and pulp of fruit was not normal, considerably affecting the consumption value.
