It is therefore suggested that preference should also be given to these traits in selection programme to isolate superior strains with genetic potentiality for higher seed yield. Path coefficient analysis revealed a higher and positive direct effect for number of seeds per plant and seed weight on seed yield so weightage should be given to such traits in selection of parents for yield improvement.

Introduction Black gram Vigna mungo L. Hepper , popularly known as urd bean, urid or mash is an important self-pollinating diploid grain legume and belonging to the family Fabaceae. It contains sulphur containing amino acids, methionine and cysteine and also contains lysine, which are excellent component of balanced human nutrition.

The dried seeds are used to make dal, soups, and curries and added to various spiced or fried dishes. In spite of its various uses, its cultivation is decreasing day by day both in acreage and yield which badly effects on human health Sohel et al.

The productivity of urd bean in the state as well as in India is very low due to various constraints like; non-availability of quality seed of high yielding variety, seeds germinate in mature pod itself if there is rains at maturity time of crop and the crop is highly sensitive to high intensity rains etc.

Thus, the crop requires due attention to increase its production and productivity in terms of its quantitative and qualitative values. Microbial proteases are executing a large variety of functions and have important biotechnological applications. A novel protease producing bacterial strain was isolated from the local soil sample. The bacterium was gram-positive and The bacterium was gram-positive and forms spore during an adverse condition in the growth medium.

After different tests, it was suggested and the features agreed with the description of Bacillus subtilis in Bergey's Manual of Systematic Bacteriology.

It was also characterized and identified by using a bioinformatics tool PIB that suggests the organism was B.

The experimentally determined isoelectric point was 5. We found that proteolytic activity of the enzyme was Native enzyme preparations typically showed a Michaelis constant Km and Vmax of 0. The enzyme was also seen to be able to remove blood and curry stain from clothes; making it a very promising candidate to be used in a leather, poultry and detergent industry.

A number of companies such as NOVO chemicals started to produce Novozymes for tannery and poultry industries. A high alkaline protease producing bacterial strain was isolated and identified a local soil sample.

The organism was gram positive and forms spore during adverse condition in the growth medium. After various tests it was suggested and After various tests it was suggested and the features agreed with the description of Bacillus subtilis.

It was also identified as B. The enzyme hydrolyses a number of proteins including azocasein which suggests that it is an extracellular alkaline protease. The esterase preferentially hydrolyzed short-chain fatty acids. This microbial enzyme was partially purified by ammonium sulfate fractionation, dialysis, DEAE cellulose chromatography and electrophoretic analysis. In future the tanneries will use a combination of chemical and enzymatic processes.

In practical applications, protease is a useful enzyme for promoting the hydrolysis of proteins and showing significant industrial applications. Salmonella have been found to be the major food borne disease in the world with a serious public health problem.

The presence of any serotype of Salmonella in food under that food unfit for human consumption. Poultry eggs are considered Poultry eggs are considered as major sources for these pathogenic microorganisms.

Plant biotechnology

The current study was carried out to isolate and identify the Salmonella spp from egg sample collected from different retailer markets and farm of Savar area, Bangladesh. Antibiotic susceptibility test was also done to determine the resistance pattern. A total of 50 poultry eggs were examined. Salmonella spp, were isolated by culturing on selective plate and characterized by biochemical tests.

All identified isolates were tested for antibiotic susceptibility to six commonly used antimicrobials by disk diffusion technique. Salmonella isolated from egg surface were found more antibiotic resistant than that of egg yolk.

The present study suggests that poultry eggs are potential reservoir of antibiotic resistant Salmonella. Cymbopogon citratus Lemon grass is a widely used herb in tropical countries, especially in Southeast Asia Shah. The plant aerial part is specially known for its extensive properties of volatile oil. The aerial part and The aerial part and the essential oil extracted has wide range of its utilization in aromatherapy, antibacterial, antifungal and insecticidal property.

Cymbopogn citratus aerial parts boiled with garlic and ginger paste is used in various food as a flavouring agent. Based on the consideration of a property with wide array of its use for edibility purposes and diverse concept of its specificity due to a presence of the constituents; an experimental research study is focused upon its application on 'Ants' as insect repellent and its use in preservation methodology which may form a substitute in terms of its natural ingredients.

The experimental work carried on confectionery product 'Candy' concludes desired effect along with a way for its use in preservation technique. A Biomaterial for Sustainable Agricultural Practices. Sustainable Agricultural Practice plays integrated role by increasing the efficiency of soil.

Such agriculture practice is followed by various methodologies with the use of biodegradable organic material. This biomaterial enriches the This biomaterial enriches the soil by increasing the components like Carbon [C] and Nitrogen 5881.

Organic rich quality farming practice ensures oneself with adequate profit causing no harm to the environment and boosting soil fertility as required for plant growth. Thus maintaining the sustainability of soil as a media to be used for a next cycle of cultivation.

Use of hazardous chemicals leads to a dropdown in soil fertility with decrease in organic matter further affecting a quality of crop produce.

Hence, tremendous need for biodegradable materials to increase quality farming and crop product has become an utmost necessity in the field of research and development.

This research paper aims to study soil media when mixed with suitable biodegradable organic materials. An experimental study of formulation with a mixture of different organic materials in-order to prepare a suitable biomaterial.

This biomaterial is treated on soil and analyzed for its pH and increase of organic matter in soil.

The research concludes a potential increase in organic matter leading to the stability of soil developing a potential for growing crops under sustainable agricultural practices. Self-Incompatibility and its Genetic Control. Self-Incompatibility was first reported by Koelreuter in Verbascum phoeniceum Purple mullein also known as velvet plant.

Self-Incompatibility refers to the failure of pollen to fertilize the same flower or other flower of the same Self-Incompatibility refers to the failure of pollen to fertilize the same flower or other flower of the same plant. Self incompatibility is an important out breeding mechanism, which prevent autogamy and produce allogamy.

Inbreeding means the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically self-pollination. View Comments. African Journal of Biotechnology Plant biotechnology: A key tool to improve crop production in Rwanda. Rwanda's economy relies on agriculture; nevertheless, crop production remains insufficient for both local consumption and exportation. Overall, enough agriculture yields in Rwanda to ensure food security has not yet been achieved In this context, this study aimed at gathering the information on Rwanda's agriculture based on different research reports and Rwandan's government established policies to identify constraints to agricultural production faced by farmers and applicability of plant biotechnology.

It was revealed that intensive and appealing discussions about agriculture economic importance, production of improved crops and the use of all necessary resources to ameliorate agricultural production need more attention. This review attempts to discuss the current problems facing agriculture in Rwanda and feasible solutions stressing that planning strong-long term policies, promoting crop breeding and use of plant biotechnology tools together with modern agriculture resources can boost up and transform economic developmental progress of Rwanda.

Genotypic variability in salt tolerance of Vicia faba during germination and early seedling growth. Salt tolerance of four Egyptian Vicia faba L. The variability in seed size was wide as seed index of Giza 3 was about half that The variability in seed size was wide as seed index of Giza 3 was about half that of Nubaria 1. The four investigated cultivars can withstand up to mM NaCl; with marginal reductions in germination capacity but with marked reductions in speed of germination and embryo growth.

The vague genotypic variability among the four cultivars in germination parameters emerged more clearly under salt stress. The response of early emergence of the embryo to salt stress seems to differ from that of the subsequent extension of embryonic axis; since based on magnitude and speed of germination Nubaria 1 was the most salt sensitive cultivar but exhibited relatively high salt tolerance on the basis of embryo growth.

The salt-sensitive Nubaria 1 produced smaller embryo, with shorter and thicker radicles than the other three cultivars. Germination speed and embryo growth were maximum but lag period was minimum for the medium-sized seeds.

Length and thickness of the emerging radicles were affected more by the genotype than by salinity stress and nutrient supply during germination. The beneficial effects of nutrients on seed germination and embryo growth were more evident in the salt-tolerant Nubaria 2 than in the salt-sensitive Nubaria 1. Production and hosting by Elsevier B.
