Abstract


The study was conducted in the central farm of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka during November to March, 2017 to screen varietal performance of tomato against the infestation of white fly and tomato fruit borer. Ten varieties of tomato e.g., BARI Tomato-2, BARI Tomato-3, BARI Tomato-14, BARI Tomato-15, BARI Tomato-16, BARI Tomato- 17, Sonali-35, Solar, Bijli-11 and Sonali-12 were screened against these two insect pests and considered as treatments. The field study was laid out in single factor Randomized Complete Block Design (RCBD) with three replications. At 50 days after transplantation (DAT) the maximum number of white fly plant-1 (27.97) was recorded from Sonali-35 and the minimum number of white fly plant-1 (19.23) was recorded from BARI Tomato-3. The highest number of branches, leaves, inflorescence plant-1 was recorded in BARI Tomato-3 plot and lowest was recorded in Sonali-35. The highest percentage of branches, leaves, inflorescence infestation was recorded in Sonali-35 and lowest was recorded in BARI Tomato-3. At 85 DAT the maximum number of fruit borer plant-1 (10.70) was recorded from Sonali-35 variety and the minimum number of fruit borer plant-1 (9.06) was recorded from BARI Tomato-3. At 85 DAT the highest number of infested fruit plant-1 (4.13) was recorded from BARI Tomato-16 variety and the lowest number of infested fruit plant-1 (3.12) was recorded from BARI Tomato-3. Total number of fruit plant-1, individual fruit weight, and weight of fruit plot-1 and yield of different varieties varied significantly due to infestation and performance of variety. The highest yield (53.83 t ha-1) was obtained from BARI Tomato- 3 variety and the lowest yield (47.01 t ha-1) was obtained from BARI Tomato-15. All varieties were infested by white fly and fruit borer but the BARI Tomato-3 variety was less damaged among 10 tested varieties and considered to be more tolerant against whitefly and fruit borer which resulted in higher yields as well.

Abstract
An experiment was conducted at Horticultural farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to asses the response of foliar application of GA3 with different concentrations to cherry tomato plants. The assessment expressed that the foliar application of 200-ppm gibberellic acid solution provided maximum number of leaves (16.7), tallest plant (70.0 cm), early flower bud initiation (13.0 days), early flowering (16.0 days) and early fruiting (20.3 days); utmost fruit diameter (25.9 mm) and number of fruits (105.0 fruits) per plant; maximum single fruit weight (11.1 g) and total fruit weight (1.2 kg) per plant, whereas the control was lowest.

Abstract
An experiment was conducted at Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2010 to March 2011 to study the consequence of potassium levels (0, 120, 150 and 180  kg K2O ha-1 ) on growth and yield of tomato. Potassium application significantly increased number of leaves, flowers, fruits, weight of an individual fruit and yield of tomato. After 60 days  of transplanting the tallest plant (75.5 cm), maximum number of flower cluster (11.2) and fruit per plant (12.2), average fruit weight (139.2g) and highest yield (59.5 t ha-1) was obtained from K1 (120 kg K2O) while the shortest plant (70.3 cm), minimum number of flower cluster (8.1) and fruit per plant (10.3), average fruit weight (101.7g) and lowest yield (51.3 t ha-1 ) was produced  by 0 kg K2Oha-1 (control).

Key words: Potassium, Tomato and Yield.

Abstract
A study was conducted in the Boendra region of Rajshahi district with 30 farmers from 15 farm families with the objective to determine the effect of improve techniques for family chicken rearing compared with traditional practices. Same structured questionnaire was used for collecting data before and after intervention. Training and technical support were given to the selected farmers emphasizing supplementary feeding and vaccination along other techniques for native chicken rearing. Average flock size per household was 22.27 ± 3.26 and 31.26 ± 3.27 respectively, for pre and post study period and differed significantly (P<0.001) from 22 to 31 (41% increase). In the pre and post project period, the average number of egg for each hen was 44.40 ± 1.41 and 68.07 ± 1.41 respectively. Fifty percent survivability of birds was increased significantly (p<0.001) in comparison to before study. Egg consumption was significantly (p<0.05) higher from 128.80 ± 13.741 to 190.00 ± 13.74(48.43% increase) per family during the study period with regards to before status. It was revealed from the study that the income per family was increased significantly (p<0.05) following adaptation of improved techniques on native chicken rearing from 1797 to 3017 (67.89% increase) than the traditional practices before. The findings of the present study clearly demonstrated that any technological intervention in family chicken rearing resulted in positive influence on egg and meat consumption and income generation which has direct impact on poverty reduction and women empowerment at the grass root level. It also be concluded from the results that introduction of improved techniques through training to the farmers especially in women would obviously boost up the family chicken production in Bangladesh.

ROLE OF DEHYDRATION RESPONSIVE ELEMENT BINDING PROTEIN-1 IN TOMATO TREATED WITH VARIOUS ABIOTIC STRESSES

Abstract
DREB1 (dehydration responsive element binding protein-1) plays important roles in the regulation of plant resistance to various abiotic stresses. In the present investigation, a cDNA clone coding a LeDREB1 gene was isolated from a cDNA library of tomato leaves (Lycopersicon esculentum) and named as LeDREB1 and its sequence signatures and expression patterns of the transcripts were observed under various abiotic stresses. This gene contains an open reading frame (ORF) of 301 amino acids encoding a DREB1 protein. LeDREB1 contained one conserved AP2/ERF domain and its amino acid sequence was similar to the DREB1 group of the DREB family from Medicago truncatula, oryza sativa, Hordeum vulgare subsp. vulgare, glycine max, and the cynodon dactylon. Genomic DNA-blot analysis for LeDREB1 suggested one locus in the Lycopersicon esculentum genome. The tissue specific expression profiling indicated that LeDREB1 was expressed in different parts and especially the highest expression was found in young leaves and roots and weak expression in stem and mature leaves. Transcription of LeDREB1 was induced in response to high salinity, drought, cold, but not ABA. These results demonstrate that the LeDREB-1 gene may be responses to abiotic stresses in tomato and useful in improving of plant tolerance to abiotic stresses.
