Evaluation of summer tomato mutants for higher yield and good keeping quality

ABSTRACT

A pot experiment was carried out at the pot yard of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh during kharif-1 season to evaluate the performance of five summer tomato genotypes (CLN 2418, CLN 2443, CLN 2366, CLN 2413 and J-5) on the basis of some important morphological and yield components. The experiment was conducted in Completely Randomized Design with three replications. The collected data were analyzed statistically and means were adjudged by DMRT at 5% level of probability. Results revealed that there were significant genotypic differences in respect of all parameters studied. It was further revealed that in general, high yielding genotypes showed superior performance in respect of yield contributing characters compared to low yielding ones. The genotypes, CLN 2418 and CLN 2443 produced higher fruit yield (1.49-1.54 kg plant-1) with the highest being in CLN 2418 (1.54 kg plant-1) due to its superiority in respect of all yield contributing characters. In contrast, CLN 2366 produced the lowest fruit yield (1.25 kg plant-1) due to poor performance in yield contributing characters. Further, harvesting duration was the highest in CLN 2418 (36 days) and the lowest was in CLN 2443         (30 days). But the keeping duration was the highest in CLN 2443 (9 days). CLN 2418 also showed 7 days shelf life when stored in room temperatures without deteriorating the quality in summer season.

Universal guideline for developing ordinance on university research co-ordination division

ABSTRACT

University is known in the global village for its two objectives (1) teaching and research. Without research and publications-university teaching position is useless/valueless or worthless. The more the research, the more the publications, the more the honor and respect for the university teachers. Usually, university demands 20-30% teaching and 70-80% research from dedicated teachers and no alternatives. Teachers can involve himself/herself in research through supervision of master and PhD students and national and/or international research projects including projects through Mother University. Without significant contribution/publication, it is difficult to involve in the international research projects. But it is easy for most teachers for involvement in own university research project. For proper distribution, management and smooth running the research projects university primarily requires a research division or department like a separate unit/cell. Such research division/Dept./cell must properly handle the internal university research projects through a sound ordinance [that can be changed when necessary] for proper distribution, monitoring and evaluation including submission of bill vouchers and reports. Without strong research division/cell, university research system of teachers may not run properly. Here author’s wide experiences were applied and established a sound ordinance for building/developing a strong research division/Dept./cell, and this can be used as universal challenge for proper managing the university research projects to the teachers. Moreover, under such guideline, corruption of money in project work/research can be largely omitted/avoided. Finally, every year some good research achievements must come out for the university as national and/or international success/goal.

Assessing of potential impacts and framing of mitigation measures for bridge construct over Dhaleshwari river, Tangail, Bangladesh

ABSTRACT

The study was conducted to assess the environmental impacts on proposed Golchattor Bridge is planned for construction over the River Dhaleshwari at Tangail district. Primary data were collected from field survey, focus group discussion (FGD), questionnaire survey (QS) and key informant interview (KII), whereas secondary data were collected from different books, journals, published documents of LGED and DoE. The result found that the air quality and noise level did not exceed the Bangladesh standard, and surface water quality was also within the permissible limit. During the construction and operation phase of the proposed bridges, the main environmental issues are air and dust pollution, noise and vibration, solid and hazardous waste, liquid waste discharge, etc. The study also depicted that risk of contamination in soils, groundwater and surface water from liquid waste and leaks of hazardous materials during handling, transportation and storage at the site. During the operation phase, the ambient air and noise quality may be affected and a risk of increase in road traffic and road accident. Magnitude of impact matrix in project activities at the pre-construction, construction and operation stage are as 1.19, 0.96 and 0.94 where pre-construction, construction and operation impact is low. The effective implementation of EMP and allegiance with the Local Government Engineering Department assists in minimizing the environmental impacts to acceptable levels.

Key words: EIA, Dhaleshwari River, mitigation, EMP, Bangladesh.

Saline tolerance of vine vegetable crops grown in southern coastal region for nutritional security

ABSTRACT

A study was conducted on saline tolerant vegetables with their mineral constituents for nutritional security during July 2020 to June 2021. Edible portions of bottle gourd, sweet gourd, sponge gourd, snake gourd and ridge gourd were collected from three selected locations of Borguna and Patuakhali districts. The locations were Sawdagarpara of Borguna district as well as Pakhimara of Khepupara upazilla and Dumki of Patuakhali district. It is noted that the soils of Borguna generally contains high saline in dry season; but during the sampling period the soil at Sawdagarpara observed moderately saline (EC value 6.2 dS m-1) and this might be due to high rainfall during the study year. The vegetable were analyzed for P, K, Ca, Mg and S. In saline area cooperatively lower accumulation of P and higher accumulations of K, Ca, Mg and S were found in most of the vegetable than that of non-saline area. Therefore, the discussed vegetable could be grown in saline area for sufficient mineral compositions. Considering the achieved findings the studied vegetables can tolerate moderate salinity (soil EC value up to 6.2dSm-1) and they can be recommended to grow commercially in the study area for nutritional security. The trend of minerals accumulation in most of the vegetable was Ca>Mg>P>K>S. On the basis of total minerals content the trend of vegetable was found as bottle gourd>ridge gourd>snake gourd>sponge gourd> sweet gourd.

Comparative yield performance study of some rice mutants at Pabna district of Bangladesh

ABSTRACT

The present research was conducted at the farmer’s field of Pabna during Aman season 2020-21 to investigate the growth and yield performance of rice mutants. The experiment was arranged in a randomized complete block design consisting of two rice mutants (viz. Kas-80-C-1, RM-16-N-8, BINA dhan-17 and BRRI dhan-87) as treatment and replicated thrice. All the growth, yield attributes and yield were substantially influence among the rice mutants except the phenological parameters. Results of the experiment showed that the highest plant height in BRRI dhan-87 (134.33 cm) and BINA dhan-17 was found better in respect of maximum seed yield (6.5 ton/ha). Therefore, findings of this study suggested that BINA dhan-17 would be suitable for better productivity and recommended for cultivation at Pabna region in Bangladesh.

Effect of sowing method on jute seed quality at Kishoreganj and Patuakhali districts of Bangladesh

ABSTRACT

An experiment was conducted at two locations of Jute Research Regional Station (JRRS), Kishoreganj and Jute Research Sub Station (JRSS), Patuakhali to find out the seed quality as influenced by different methods of sowing. Three popular varieties e.g., Robi-1, O-9897, JRO-524 and three sowing methods e.g., direct seeding, top cutting and seedling transplanting methods were used as experimental treatments. The experiment was carried out in RCBD with three replications. Results revealed that the highest 1000-seed weight (2.097, 2.123), moisture (9.05, 9.19), germination (98.70, 95.22) and field emergence (85.77, 83.89) were found in Robi-1 both at Kishoreganj and Patuakhali, respectively. In case of sowing methods, the highest 1000-seed weight (2.083, 2.173), moisture (9.22, 9.34), germination (98.11, 93.56) and field emergence (88.36, 79.83) were found in top cutting method in studied districts of Bangladesh.
