A swap would help Morocco to conserve the environment by using cleaner energy, as well as moving towards meeting Morocco’s emission targets. For this purpose, we surveyed 112 farmers in two Moroccan regions, Sidi El Aidi and Fquih Ben Salah. We found that pumping one cubic meter of groundwater with solar energy was in average 33.3% cheaper in Sidi El Aidi, and 60.6% cheaper in Fquih Ben Salah than pumping using LPG. Net present value estimates suggest that investing in solar panels is profitable. Environmental analysis suggested that switching from LPG or diesel to solar energy would save the equivalent amount of energy used by 13– 25 million 60-W electric bulbs per year. The government, farmers and the environment would gain by replacing LPG with solar energy. However, once solar panels are installed, pumping cost is virtually zero. Farmers may be tempted to overuse irrigation water, and consequently accelerate the depletion of groundwater. Implementing groundwater regulations to control the amount of groundwater pumped should precede any government program intended to promote solar energy.

This research work was targeted at preparing compost from different organic material combination and assessing the phytotoxic effects of different compost combinations. Compost of organic materials was prepared and fortified giving the following combinations: PM+RB+BM+GL, PM+SD+BM+GL, PM+RB+GL and PM+SD+GL. The carbon and nitrogen sources were combined using 1:3 ratio, the combination was sprinkled with water. Data such as ambient temperature of each pile was taken daily, while pH and electrical conductivity tests were taken on samples fortnightly. On maturation of the compost, post fortification technique was carried out hereby creating two more combinations tagged PM+RB+GL (BMP) and PM+SD+GL (BMP). The six compost combinations were tested in terms of their germination percentage, after which data on germination %, relative germination %, root length, weight gained and germination index were taken and analyzed using anova, their mean were separated using Duncan Multiple Range Test (DMRT) at 5% probability level. Fortification with phosphorus source at the onset of composting promoted plant growth hence no sign of phytotoxicity while fortification with phosphorus source after maturation increased phytotoxicity.

Cookies were made from the composite flour samples and analyzed for sensory composition. The fat content of the cookies were extracted and evaluated for iodine value, free fatty acids, saponification va lue and fa t ty acid composition. The fatty acid composition was analysed by gas chromatography–spectroscopy. The iodine value, FFA and saponification values varied from 20.3 – 32 gI2/g, 0.55 -0.82% and 27.49 67.04 mgKOH/g respectively.

Tiger nut flour has been demonstrated to be a rich source of quality oil and contains moderate amount of protein.

The present study was conducted to assess the dietary diversity pattern and its correlates in a rural setting of Jaunpur, Uttar Pradesh, India. A cross-sectional household survey was conducted during August-November 2017, among 316 households. Women from these households were interviewed to know the variety of foods consumed in the past 24 hours. Descriptive statistics and ordinal logistic regression analysis have been used to meet the objective of the study. Results portray that, about 14 percent of the households were in the category of low dietary diversity, and 58 percent were under medium dietary diversity. A higher proportion of SCs and poor households were more prone to have low dietary diversity. Landless households or less than one bigha of agricultural land and household without livestock or less number of livestock were more prone to low dietary diversity. Results of ordered logistic regression analysis confirm that caste, working status of heads, family type, socioeconomic status of the household, agricultural land, and livestock showed a significant association with the dietary diversity pattern of households. There is a necessity for the informed rural population on the importance of a diverse diet to improve nutrient consumption and to achieve food and nutrition security. National or regional level surveys will be helpful to understand the food related challenges in India.

Under saline conditions, rapid and uniform germination of plants would be necessary to achieve enhanced quality and potential yield. In such situation, seed priming could be an important approach to increase plant germination, growth and consequently yield. Priming is defined as seed presowing in solutions that allow them to imbibe water to improve the first stage of germination; however, this prevents radical protrusion through seed coat. Seed priming improves establishment in many plant species, and include hydro-priming, osmo-priming, halo-priming, thermo-priming and hormo-priming. Overall, accelerated biochemical and physiological process such cell division and starch hydrolysis, induced I±-amylase activity, greater germination rate, less Na+ and higher K+ accumulation and induced antioxidative system might be some mechanisms for salinity tolerance in primed plants. Since shortage of water availability due to osmotic stress is the first phase in salt stress, so one of the major mechanisms for improved germination and growth in primed seeds is accelerated water imbibition under saline conditions. In this paper, different seed priming strategies are examined and comprised in different plants growing in saline conditions. Since different types of seed priming have positive effects on germination, emergence, growth, yield as well as biochemical traits and quality of plants, it seems that seed priming could be promising approach for improved salinity tolerance in future world with changed climate. More researches on detail of seed priming for each agent is needed for each plant.","PeriodicalId":92332,"journal":{"name":"Asian journal of agriculture and food science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44564707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of present investigation was to reveal the effects of different colored shade nets on berry skin color and functional properties of grape juice. Four years old vines of ‘Alphonse Lavallee’ table grape were cultivated soilless in about 70 L black plastic pots containing sterile peat and perlite mixture under controlled glasshouse condition. The grapevines were covered with different colored shading nets (yellow, blue, white, red, green and black) at the beginning of the summer period. At commercial maturity, investigations show that berry skin color and the analyzed biochemical features of ‘Alphonse Lavallee’ table grape cultivar displayed great variations in response to the different colored shade net. Such differential effects should be evaluated when the use of shade nets is considered in protected viticulture to cope with environmental constraints. The findings may also be useful for the future experiments under conventional vineyard conditions.","PeriodicalId":92332,"journal":{"name":"Asian journal of agriculture and food science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41341793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
