Purposive selection of site was done, and sampling procedure was simple random sampling technique. Descriptive statistical tools, chi-square test and t-test were used to analyze the data. The study was carried out to know level of adoption of improved orchard management practices, relation between socio-economic characters and adoption of technology and to identify the constraints perceived by farmers during adoption. From the study it was found that majority of the respondents of mandarin growers were male, middle aged, had medium sized family, had medium farm size, most of them are literate and agriculture was the primary source of income. Majority of farmers had taken training. Most of the respondents were in frequent contact with extension agent seeking the required information. Out of major ten improved management practices, majority of respondents had adopted training and pruning while least adopted practices were micronutrient application. Majority of respondents had low adoption on recommended management practices. Gender, education level, training, land holding size, contact with extension agent had significant association with adoption. Major problems like irrigation, insect and disease, training, lack of labor and cost of input were encountered during the adoption of improved mandarin orchard management practices. It is recommended that, literacy program needed to be strengthened, training should be based on felt need and subsidy should be given to farmers to encourage them towards mandarin cultivation as well as adoption of improved orchard management practices.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43865001","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}

Rice feeds more than 50 % of the world population Rice is predominant staple food for 17 countries in Asia and provides 20 % of world's dietary energy supply. So, among cereal it considered as most significant crop. Both biotic and a-biotic factors adversely affect crop and yield. Among them, 70 to 80 % of annual rice yield is lost due to blast disease. Higher statical data of blast disease is threat to growing population on food security. The objective of this review is to know the different methods of controlling blast diseases. Management of blast can be done through various methods but ecofriendly, integration of various cultural, Nutrient, chemical biological and botanical is best. Recent Research has been made in biological, botanical, Resistance development and Nutritional management but development of variety and Biological are best option. Isoprothiolane at 1.5 ml/l and Tricyclazole 22 % + Hexaconazole 3% SC (thrice from booting stage at weekly interval) are best chemical whereas Pseudomonas fluorescens strain Pf1 @ 10g/kg, SPM5C-1 and SPM5C-2 (aliphatic compounds obtained from Streptomyces sp), Bacillus tequilensis (GYLH001) and pseudomonad EA105 effectively inhibit the growth of M. oryzae. more than 100 R gene are identified as Resistance in Blast. Gene Pyramiding and use of multilines varieties is efficient and able to overcome pesticide hazards. Neem extract 4ml/15ml, Coffee arabica@25%, Nicotiana tabacum@10% are effective but garlic extract @higher doses and neem extract @ 4ml/15 ml are best for complete control. 4 g Si/L in green house condition observed greatest reduction of blast incidence.

More than the pungent aroma the fruit is well-known for, it is said to be beneficial to health as it contains many antioxidants and bioactive compounds that have different potentials for positive impacts on health. However, there is scant existing literature which gives an overview on the amounts of bioactive compounds in several varieties of durian in Southeast Asia, and the relevant health benefits. This review article therefore seeks to consolidate the literature which have identified bioactive compounds and investigated antioxidant activities in durian cultivars from Malaysia, Indonesia, Thailand and China, and studies that have given insight on potential medicinal properties of durians. A literature review was conducted using databases Scopus and ScienceDirect and a total of 30 articles were reviewed. Total polyphenols and flavonoids were highest in the Mon Thong cultivar compared to other Thailand varieties, and ripe or overripe durians were found to contain the highest amounts of polyphenols and flavonoids. Durians were also found to contain medicinal properties, such as anti-inflammatory and antidiabetic potential, and protective effects on cardiac health. Further research on these bioactive compounds in the nutritious fruit with potential medicinal properties can contribute to the medicinal value of durians, as well as benefit the pharmaceutical industries.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44222033","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}

Drought-stressed loss in wheat yield likely exceeds losses from all other causes, since both the severity and duration of the stress are censorious. Here, we have reviewed the effects of drought stress on the morphological, physiological, and biochemical attributes along with the growth impacts, water relations, and photosynthesis impacts in wheat. This review also illustrates the mechanism of drought resistance in wheat. Historical drought years in Nepal have been identified and the yield losses were assessed. Wheat encounters a variety of morphological, physiological, biochemical responses at cellular and molecular levels towards prevailing water stress, thus making it a complex phenomenon. Drought stress affects leaf size, stems elongation and root proliferation, imbalance plant-water relations and decline water-use efficiency. Different types of physiological research are ongoing to find out the changes occurs in the wheat plant as a result of drought stress. Morphological changes can be looked through two ways: changes in root system and changes in shoot system such as effects on height, leaf senescence, flowering, and so on. Physiological changes involve changes in cell growth pattern, chlorophyll contents, photosynthetic disturbances, plant-water relations, etc. Biochemical changes occur in different chemical, biomolecules, and enzymes. Plants portray several mechanisms to withstand drought stress which can be classified as Drought escape, Drought avoidance, and Drought tolerance. Selection of wheat genotype that can tolerate water scarcity would be suitable for the breeding program aiming to development of drought tolerant variety under water limited regions.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41944891","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}

Malaysia, which imports about 35 percent of its rice, is the 13th largest importer of rice in the world. This makes Malaysia susceptible to global rice crisis, similar to the one in 2008. Climate change is crucial in affecting rice production in tropical countries especially Malaysia as climate projections have shown that climate change will affect countries in the tropics most negatively with increased temperature and flooding due to anthropogenic carbon dioxide emissions. This study analysed the effect of anthropogenic carbon dioxide emissions on rice production in Malaysia during the period 1970-2013. The analysis incorporated the following variables: total local rice production, carbon dioxide emissions, precipitation, land used for paddy farming, total rice imports, and global average crude oil prices. The results indicated that in the estimated model the level of carbon dioxide does not affect rice production in the short- run. However, increased carbon dioxide emissions can influence rice production indirectly by affecting the level of precipitation. Precipitation and area of irrigated land are significant variables in determining level of rice production. Policies for reducing carbon emissions is however crucial for ensuring long run sustainability in rice production.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46313299","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 snails were randomly assigned to three treatments and each treatment was replicated three times with 10 snails per replicate. The snails were exposed to different light duration. Treatment 1 had 12 hours light and 12 hours darkness, Treatment 2 was subjected to 18 hours light and 6 hours darkness, Treatment 3 was subjected to 24 hours light. The data collected was analysed using one-way analysis of variance and Duncan multiple range test for significant mean separation. Data were collected on feed intake, weight gain, time of feeding and reproductive behaviors. The results of the experiment showed that there were no significant differences (P>0.05) in final weight gain, average daily weight gain, total feed intake, average daily feed intake, feed conversion ratio, duration of courtship, duration of feeding and cost of feed per kg weight gain between treatments. The results also showed that there were significant differences in number of eggs laid and mating duration between treatments. From the result, it was concluded that the best photoperiod for Achatina achatina is 24 hours light as it produced the lowest feed conversion ratio and cost of feed per kg weight gain and that was recommended for effective growth of Achatina achatina.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47017650","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}
