Intakes of adequate and quality food on sustainable basis are prerequisite for good health. However, food security cannot be achieved amidst security challenges. In the recent decade food production in Nigeria has been a challenge. This is owing to many reasons, including security challenges. The aim of this study was to provide information on the deplorable state of food production in Nigeria, as triggered by security challenges. This study also highlights impacts of the security challenges on food affordability, and consequently its effects on hunger and malnutrition in Nigeria. And by extension, this study conceptualized food production focus model (FPF) that if adopted, could improve rural food production in Nigeria. Databases such as Google Scholar, African Journals Online, Nigerian Journals Online, Scopus, Medline and Pubmed were used to search for relevant information on the impacts of the security challenges on farmers productivity. Findings from literature search revealed that access to sufficient, safe and quality food is now a serious concern in Nigeria in recent time due to the security challenges, coupled with increased population growth, rural-urban migration. Although migration may be multifaceted, however, security challenges play substantial roles, and have seriously affected the food production in several rural communities in Nigeria. And most worrisome is increased unemployment rate due to lost of jobs and investment phobia caused by the security challenges in Nigeria. Furthermore, the scourge of COVID-19 pandemic amidst the security challenges have further aggravated food and nutrition insecurity in Nigeria.

Bangladesh is an agro-based country. Several vegetables and fruits contribute greatly to the national economy. Fruit fly species (Diptera: Tephritidae) have been a serious threat to agriculture in Bangladesh as well as worldwide. Morphological identification sometimes creates misidentification in adult stages, while in eggs, larvae and pupal stages are totally difficult. Nowadays, molecular identification based on DNA barcoding is an effective and rapid identification tool. However, this technique is very limited use in Bangladesh. In this study, adult samples were collected (trapping with ME and CUE) from three different geographic locations (Dhaka, Chittagong and Barisal) of Bangladesh. Adult flies were identified based on DNA barcoding (amplify the sequences with COI gene), and larvae were identified based on species-specific primers. Bactrocera dorsalis (Hendel), Zeugodacus tau (Walker) and Zeugodacus cucurbitae (Coquillett) were identified adult species found in all the locations, whereas B. dorsalis was found in a higher number. In case of host fly identification on the basis of larvae, B. dorsalis was identified from guava in three locations, indicating guava fruit is the suitable host in Bangladesh. Proper management should be taken to control these pest species; otherwise, they will become a great threat to the agriculture of Bangladesh.

Fruits & vegetable commodities incur huge loss in field & postharvest conditions due to infestation by Tephritid Fruit Flies. The adult female flies lay eggs inside near maturity fruits & vegetables. The eggs hatch into apodous larvae which feed on the pulp; making them unfit for human consumption and marketing. Using male pheromone lures like Cue Lure & Methyl Eugenol Lure is one of novel techniques for annihilating male fruit flies only. Female flies can still mate & keep ovipositing fruits. So, an experiment was carried at Maranthana, Pyuthan, Nepal with 3 replications & 7 treatments to devise techniques for female fruit flies management. The experiment comprised of commercially used pheromones like Cue Lure & Methyl Eugenol Lure and 5 home based baits viz. Apple Cider Vinegar, Yeast fermented sugar, Tulsi Lure, Local Liquor Lure & Pumpkin Lure; all poisoned with Malathion, soaked in cotton wick and assembled in Lynfield traps. The experiment was completed in two trappings; 2021/04/18 to 2021/05/09 and 2021/04/16 to 2021/07/07; with similar results in both trappings. The commercial were able to attract the highest number of flies; all of which were male. Local liquor lure & tulsi lure attracted least number of male fruit flies. The Apple Cider Vinegar Lure and Yeast Lure attracted both male & female flies while pumpkin lure attracted only female flies of genus Zeugodacus. Results revealed that female flies of genus Zeugodacus tau & Z. cucurbitae could be attracted efficiently by making use of Apple Cider vinegar and Pumpkin.

A most valuable fungus that has multiple benefits in the agriculture production system. Around the Globe, Framers and scientists have taken the benefit of knowledge on trichoderma use. It is also called as multipurpose fungus because of its use as bio fertilizer as well as biofungicide (Bio agent). Trichoderma is being able to produce volatile compound and ability to solubilize phosphate making them available to plants, it’s used as biofertilizer. As a bioagent it control various pathogens such as Rhizoctonia, Phytophthora, Sclerotinia spp. Presently a large number of Trichoderma based formulations/ Products are available in the global market which are dominated by Trichoderma harzianum & Trichoderma viridae. Its application in developed countries is increasing rapidly replacing the chemical products, while in developing countries still it is lagging behind because of awareness among the peoples. This article is also with purpose to disseminate the awareness among the peoples about its beneficial aspects in crop production process and its contribution in the environment. The main Ambition of this review paper is also to enlight the importance of trichoderma as a biofertilizer and bio agents.

This work was carried out from 15 July 2021 in Grdarasha Field, College of Agricultural Engineering Sciences, Salahaddin University-Erbil. It aims to show the impact of using kenaf fibers as alternative materials in manufacturing. Global climate change and environment pollution cause to do this kind of researching. Kenaf (Hibiscus cannabinus L.) is a fast growing natural crops, belongs to the Malvaceae family. It is an industrial crop has high potential for cultivation in a tropical climate and also which resistance to various soil types and climate. Selecting the raw materials for industrial applications is more important. Actually, kenaf fibers have many advantages to use in wade range of applications, also it’s fibers not just a part of plant useful as raw material but also leaves and seeds have many other advantages and uses. The results show that there is a significant between varieties on growth and fiber yield properties. The highest plant high was of FH952 by (368.33 cm), while the best values of total fresh and dry stem yields were found of HC2 and V36, by almost (219.33 and 60.93 t/ha), respectively. Providing these results through kenaf plant could be considered as substitute materials for timber and other biocomposite manufactures, and also it causes to safe environment by absorption optimal value of carbon dioxide (CO2), then cutting of woodland trees will be decreased. Finally recommended to cultivation fiber crops (kenaf) globally to conserve environment.

This work was carried out from December 2016 to June 2017 in two different regions on the north of Tunisia belong to the Sub-humid bioclimatic stage on Beja and the Semi-arid bioclimatic stage on Oued Mliz. It aims to identify the varieties of chickpea adaptable on each bioclimatic stage and to evaluate the efficiency of water use for some varieties of chickpea. Indeed, analysis of yield parameters such as biological yields, weight of hundred seeds, seeds yield, number of seeds. All varieties were grown in rainfed conditions. For the sub-humid and semi-arid bioclimatic sites plant have received respectively an amount of water of 346 and 261mm. The results show that there is a significant correlation between these parameters. The cultivation of the collection of eight varieties of chickpea in rainfed soil showed an important adaptation to drought. The number of pods marked in Beja1 and Nayer varieties are the highest, because of the ability to fill the pods during the year. While other varieties have a lower number of pods indicating that spring drought could be the cause of high flower abortion, pericarp development and empty pod formation. This research revealed that in the sub-humid bioclimatic stage, all varieties adapt and produce better than on the semi-arid. The semi-arid Tunisian is characterized by the final drought which causes the hydrous stress at chickpea. The conduit of this last in these zones is dependent on the selection of the varieties early and resistant to the water deficit.

The plant pathogens as Alternaria solani, Monilinia fructigena, Botrytis cinereae and Venturia inaequalis cause significant damages on many plants in the European region (particularly in the region of Republic of Bulgaria), especially on orchard cultures which are very important for agricultural industry in this area. There is many existed commercial plant protection products towards this phytopathogens on the market and there is intensive pesticides treatments in order to be overtake infestations and damaging of the plants from this pathogenic fungus. However such king pesticides in the most cases are toxic and harmful for the humans and environment, so there is a need for development and introduction on the pesticide market of the novel environmentally friendly plant protection products against these diseases. In the present research paper an in vitro trials were conducted with ethanol extracts from tarbush plant (Flourensia cernua) with conidial sporulation of of Alternaria solani, Monilinia fructigena, Botrytis cinereae and Venturia inaequalis. The received results show the strong antisporulation action of tarbush plant ethanol extracts towards tested pathogens. However according to the conidiospores of Alternaria solani, there was full lack of effectiveness and even slightly stimulation action of germination of spores. This results can be a base for development of the new natural fungicides against tested plant pathogens wicth can be apllied as in the commersial agriculture, as in the organic or integrated pest management

Wheat production is the most common edible crop in the world, accounting for one third of the world’s diet. Therefore, the main thesis of the development of modern crop production in Ukraine is to reduce costs and introduce innovative technologies for the production of quality wheat. The quality of grain and seed depends on many factors, namely: agro-climatic conditions, sowing condition of the seed material, quality characteristics of the soil, yielding properties of seeds, pre-sowing seed treatment. etc. For this purpose, the photosynthesis and intensity of photosynthesis need to be limited to the width of the leaf and the height of the leaves by a smaller cut of the stem. It is extremely important to ensure that the head and side pagons of wheat are in good condition. All parameters are often secured by the technology of grain preparation before delivery. Prior to this technology, it is possible to introduce processing of the material in the form for the development of the material. This article presents the effectiveness of the use of infrared irradiation for the pre-sowing treatment of winter wheat seeds in Sekobra Research, Germany.

Thirteen exotic potato varieties along with four checks were evaluated at six agro-ecological locations of Bangladesh for three generations during 2015-16 to 2017-18 in order to identify table purpose and processing quality varieties. Results indicated significant variation among the varieties. Based on the results of the 1st year multi-location trial, seven superior ones were selected for further testing in AYT and RYT in next two years. In the SYT, varieties Farida and 7four7 were the highest yielders. In the AYT, the highest average yield over location was also produced by 7four7 (38.70 t/ha). Varieties Cimega and Memphis also gave comparable yields to that of 7four7 (37.33 and 36.67 t/ha, respectively). Considering the yield of the three generations, the above four varieties were significantly better than the checks. Considering the specific qualities, Farida was found most suitable for table purpose because of its high yield, medium-sized oval and smooth tubers with good eating quality. The variety Taisiya produced tubers with good size and shape, but low in dry matter content; so not suitable for processing. Memphis might be selected for French fry as it produces maximum large sized tubers with good long oval shape. On the other hand, variety Panamera is a high yielder but its plant type was undesirable. On the whole, varieties Cimega, 7four7 and Farida are suitable for table purpose, and Memphis may be selected for French fry under Bangladesh condition. None was found quite suitable for Chips preparation.

Low soil temperature (14℃–20℃) favours growing of high-value temperate crops that are known to have higher return per hectare of land than other widely cultivated crops, thereby presenting increased income to farmer. However, due to high soil cooling load, growing these crops on tropical lowland area is a challenge except through greenhouse farming or on few cool higher altitudes with resemblance of temperate climate. Greenhouse farming involves cooling the entire volume of planting zone and is energy intensive, while few cool highlands are not sufficient to achieve food security in this direction. This study aims at application of chilled water for direct cooling of soil, to create favorable soil conditions for optimal performance of planted temperate crops. However, soil cooling using vapour compression refrigeration system may not be economically viable. Solar thermal chilled water production system is presented in this study to supply the cooling. The system consists of absorption refrigeration system and dimensioned size of soil bed with chilled water pipe network. The study includes modeling of soil cooling load to determine the refrigeration power required to overcome such load. The modeled system matched well with the experiment; having standard deviation of 1.75 and percentage error of 12.24%. Parametric analysis of the soil cooling showed that temperatures of cooled soil were significantly affected by chilled water flow rates. The regression equation developed from the Analysis of Variance (ANOVA) is suitable for predicting cooled soil temperature. The cooling process is technically feasible, with potential for greenhouse gas emission reduction.
