Abstract:
Antimicrobials in food packaging are used to enhance quality and safety by reducing surface contamination of processed food. This study investigated the effects of Aloe vera- coated packaging materials on the microbial quality characteristics of breadfruit flour. Breadfruit flour was packaged in Jute bag (JB), Kalico bag (KA), low-density Polyethylene-lined Brown paper (LDPEBP) and they were compared with control. Samples were analyzed for changes in microbiological (total colony count and total fungal count) and moisture content during a storage period of 12 weeks interval during storage at ambient temperature of 25 ± 2oC. Packaging significantly (p< 0.05) affected the moisture content and microbiological of breadfruit flour during storage. The moisture content, total colony count, and total fungi count significantly (p< 0.05) increased as the storage time increased. The sample packaged in Brown paper (BP) were more acceptable than those in other packaging materials.

Abstract:
Entomopathogens are microorganisms that pathogenic to insect pest. Several species of naturally occurring viz; fungi, bacteria, viruses and nematodes, infect a variety of insect pests and play an important role in agricultural crops controlling insect pest management. This kind of biopesticide has many advantages and alternative to chemical insecticides, highly specific, safe, and environmentally sustainable. Pest problems are an almost inevitable part of agriculture. They occur largely because agricultural systems are simplified and modifications of natural ecosystems. Viruses, bacteria are host specific and fungi generally have broader host range and can infect both underground and aboveground pests, soil-dwelling nature nematodes are more suitable for managing soil pests. Growing crops in monoculture provides concentrated food resource that allows pest populations to achieve higher densities in natural environments. Some of the most important problems occur when pests develop resistance to chemical pesticides. These cause highly significant damage to crops, there are also threats from emerging new strains of pests. Crops cultivation can make the physico-chemical environment more favourable for pest activity. Agricultural pests are reducing the yield and quality of produce by feeding on crops, transmitting diseases. Agricultural production significantly loss crop yields, suggest that improvements in pest management are significant forward for improving yields. Crop growers are under immense pressure to reduce the use of chemical pesticides without sacrificing yields, but at the same time manage of pests is becoming difficult due to pesticide resistance and the decreasing availability of products. Alternative methods are needed urgently. These need to be used as part of Integrated Pest Management safety and environmental impact.

Abstract:
This study was carried out at the Teaching and Research farm Landmark University, Omu-Aran. Treatments consisted of 3 levels of cocoa pod husk ash (0, 2 and 4 tonnes CPHA ha-1), 3 levels of cocoa pod husk powder (0, 2 and 4 tonnes CPHP ha-1), NPK and the control. The experiment was laid out in a Randomized Complete Block Design (RCBD) replicated four times. The following parameters were taken plant height, number of leaves (at 2, 3, and 4 weeks after sowing), total plant weight, root weight, leaf weight, roots girth and roots length. Data collected were subjected to Analysis of Variance (ANOVA) Using S.A.S, 2000. Treatment means were compared using Duncan Multiple Range Test (DMRT) at 0.05 level of probability. Results showed that chemical analysis of cocoa pod ash and powder contained plant nutrients as N, P, K, Ca, Mg and some other micronutrients in varying proportions. Application of CPHA 4 CPHP 2 gave higher values for all the vegetative parameters. The implication of this study is that high level of cocoa pod husk powder in combination with high level of cocoa pod husk ash is detrimental to radish cultivation. In the same vein, the nutrition of radish was incomplete when NPK fertilizer was applied. It can therefore be recommended that the use of combined application of cocoa pod ash and cocoa pod powder at CPHA4 + CPHP2 was sufficient for the cultivation of radish (Raphanus sativus) in the study area as it compete favourably with application of NPK fertilizer.

Abstract:
Algerian coast contains a high species diversity of marine algae; however, there are only few reports on their bio-stimulant properties. Different concentrations of the brown seaweed Cystoseira mediterranea. Extracts were used to determine their efficiency as biostimulant of barley growth and productivity. All growth parameters and chlorophyll content were found to be highest at the 50% concentration. Our results have clearly shown that algerian seaweed extract could serve as an alternative to chemical fertilizers, as is abundant, with high quality, ecofriendly, and deliver environmental and economic benefits to farmers.

Abstract:
Sweet cherry is a type of fruit that is high on demand in exports for table consumption. Turkey is a gene centre for sweet cherry fruit. Fruits are produced over an extended period because of the ecological richness and large cultivation area, which allows Turkey to remain as the leader of sweet cherry production in the world. The variety, ‘0900 Ziraat’, also known as the Turkish sweet cherry fruit, has the highest production volume. Mazzard and Mahaleb are the commonly used rootstocks for sweet cherry cultivation; and Mazzard is used more frequently than Mahaleb. Clonal rootstocks are used to maintain cultivation in new orchards. The present study provides a detailed information on the current status of sweet cherry fruit cultivation in Turkey as well as its cultivation practices and exports. It is targeted that modern irrigation techniques, good agricultural practices, and increased cultivation areas are established to maintain Turkey’s position as the leader in global sweet cherry production and exports.

Abstract:
Major spices crops such as black pepper (Piper nigrum L.), cardamom (Elettaria cardamomum Maton.) and turmeric (Curcuma longa L.) production in India is sustained losses due to several reasons. Among them, one of the major constraints are nematode infesting diseases, which causes significant yield losses and affecting their productivity. The major nematode pests infesting these crops include burrowing nematode Radopholus similis; root knot nematode, Meloidogyne incognita and M. javanica on black pepper. Whereas, lesion nematode, Pratylenchus sp., M. incognita and R. similis infesting cardamom and turmeric crops. Black pepper is susceptible to a number of diseases of which slow decline caused by R. similis and M. incognita or Phytophthora capsici either alone and in combination and root knot disease caused by Meloidogyne spp. are the major ones. Root knot disease caused by Meloidogyne spp. is major constraints in the successful cultivation and production in cardamom. Turmeric is susceptible to a number of diseases such as brown rot disease is caused by Fusarium sp. and lesion nematode, Pratylenchus sp. and root knot disease caused by M. incognita. Adoption of integrated pest management schedules is important in these crops since excessive use of pesticides could lead to pesticide residues in the produce affecting human health and also causing other ecological hazards.

Abstract:
Some developmental projects are created by people- private -partnership (PPP), particularly where recovery is acquirable by levying the users. Such PPPs are successful for construction of roads, bridges, running toilet facilities and conveyance facility in mode of use and pay. Likewise, public Scientist Partnership (PSPs) will be successful, where monitored impacts can be used to derive benefit. But, such example cases are not so popular in utilizing new research results and derive benefits from natural resources and enhance productivity. There exists need of similar partnership projects in research area. In this study modality of the PSP to create boost engine for natural resource conservation and bringing economic prosperity is established. A novel PSP launch was synthesized on useful food crop viz finger millet (Elusiane corcona (l)), known since long past, and now regaining popularity. It was possible to enhance additional annual production of 5.755 million Tonnes of finger millet grain, equivalent to additional income of Rs 11,510 crores. Against this the scientist partnership share was 0.49x million Tonnes grain and economic equivalency of Rs 992 crores, which was just 7-8%, with same level of input in agriculture. Additional benefits were sustainability of production and resources consecration, reduction of Green House Gas emission (GHGs), particularly nitrous oxide (N2O), largely emanating from agriculture and responsible for depletion of ozone layer. The finger millet stiff stem will be useable for production of ply-board filling material that will be innovative building material for housing and infrastructure developments. and making furniture.

Abstract:
To investigate the possible role of arbuscular mycrrhizal fungi (AMF) in alleviating the negative effects of salinity on Stevia rebaudiana (Bert.), the regenerated plantlets in tissue culture was transferred to pots in greenhouse and inoculated with Glomus intraradices. Salinity caused a significant decrease in chlorophyll content, photosynthesis efficiency and enhanced the electrolyte leakage. The use of AMF in salt –affected plants resulted in improved all above mentioned characteristics. Hydrogen peroxide and malondialdehyde (MDA) contents increased in salt stressed plants while a reduction was observed due to AMF inoculation. CAT activity showed a significant increase up to 2 g/l and then followed by decline at 5 g/l NaCl in both AMF and non-AMF treated stevia, however, AMF inoculated plants maintained lower CAT activity at all salinity levels (2 and 5 g/l). Enhanced POX activities in salt- treated stevia plants were decreased by inoculation of plants with AMF. The addition of NaCl to stevia plants also resulted in an enhanced activity of SOD whilst, AMF plants maintained higher SOD activity at all salinity levels than those of non-AMF inoculated plants. AMF inoculation was capable of alleviating the damage caused by salinity on stevia plants by reducing oxidative stress and improving photosynthesis efficiency.

Abstract:
For good health, including fresh fruits and vegetables in our daily diet is very important. Fresh fruits and vegetables are highly perishable and affected by different microbial contaminants from production up to consumption. The objective of this study was to evaluate the important microbial spectrum of selected fruits and vegetables and their management from Hawassa town markets. A total of 27 fruit and 9 vegetable samples were analyzed for pathogens from their surface wash. The mean aerobic mesophillic count (AMC) ranged from 2.04x10-7cfu/ml to 4.2x10-6cfu/ml from the surface wash and the total coliform count (TC) ranged from 2.50LTBccfu/ml x10-7 to 1.5x10-6cfu/ml. Fecal coliform ranged from 3.2x10-6 to 0 cfu/ml and the range for Salmonella spp. and Staphylococcus aureus were 1.8x10-6 to 0 cfu/ml and 2.50LTBcx10-7 to 0 cfu/ml respectively. Mold and yeast count ranged from 7.6x10-6 to 0.2x10-4 from the fruit surface wash. There was statistically significant difference regarding to AMC and TC between markets in between banana and orange samples and they were detected in all fruit samples. From the 36 samples E. coli and molds and yeast were found in all fruit samples, and Salmonella and Staphylococcus aureus were detected in 89% fruit samples in each. Activities during harvesting, transportation, storage and marketing conditions favored contamination of most commonly used fruits banana and orange. Besides, poor hygiene of the venders, using microbial unsafe containers, poor handling practice and poor environmental conditions such as sanitarily unsafe marketing environment were identified to be another sources of contamination. Hence, for safe and clean supply of fruits, community members working with the fruits must be trained on the ways by which fruits can be contaminated and the safe methods of harvesting, transportation, storage and vending the fruits.

Abstract:
Dormancy is a state of lack of germination/sprouting in seed/tuber although required conditions (temperature, humidity, oxygen and light) are provided. Dormancy is based on hard seed coat dormancy or lack of supply and activity of enzymes (internal dormancy) necessary for germination/sprouting. Dormancy is an important factor limiting production in many field crops. Several physical and chemical pretreatments to production material (seed/tuber) are carried out for overcoming dormancy. Physical and physiological dormancy can be found together in some plants and this event makes difficult to provide high frequency healthy seedling growth. Whereas, emerging of all production material (seed, tuber) sown/planted and forming healthy seedling is a prerequisite of plant production.
