A significant decrease of national soybean production is caused by unfavorable price of soybean seed. Under such undesirable condition for growing soybean, farmers shift to grow other crops, such as corn and horticultural crops. An increase of soybean price to meet the benefit of the farmers and consumers would drive the farmers’ motivation to grow soybean in a larger area.

Should South Africa shut down dumped chicken imports to prevent industry collapse, despite the fact that the European Union (EU) cries foul over the chicken crisis claims. On the other hand the South African poultry industry cries foul because of the status of import duties on poultry. The paper will look at these issues with an open mind and also argues that higher import duties will not fix all of the South African poultry sectors problems. It highlights very briefly the Trade and Industry Minister’s statement that chicken farmers are at risk. In so doing other important issues will be introduced within the narrative. It must be highlighted that the South African poultry industry is one of the most sophisticated industries on the continent of Africa, and therefore analyses some of the causes for this sudden demise. This collapse of the poultry industry is very significant in a country that is battling to curb its unemployment woes due to very serious problems within its very sluggish economy and the massive retrenchments within the industry. This is the reality that confronts the country and indeed solutions must be found to deal with this vexing issue. The paper will therefore nuance some of these issues. In the conclusion to this narrative, the author will argue that the fundamental structure of the South African economy must change in order to bring about delivery of services and deal with many of the issues that confront the country in terms of general development. The paper argues that the fundamental structure of the South African economy must change. Conclusions and recommendations are made throughout the discussion and at the end of the paper a dedicated discussion is undertaken in respect of some of the recommendations and conclusions that are provided.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123333605","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}

Periodic irrigation or rotation technique was one method that in addition to making the soil healthy, it also saves the use of irrigation water through water balance technology. The objective of this paper is to discuss the management of water stream through technology of water balance in Bali Province, Indonesia to be used for the consideration of a policy by local government to support the program of one river one management. The research on water balance was conducted in the Yeh Ho watershed which was located in the Tabanan district, Bali Province stretching from the Batukaru mountains in the north to the Indonesian Ocean in the south. In the north it was bordered by Buleleng regency, in the east it borders Badung regency and in the west with Pupuan sub-district Tabanan regency. The length of the Yeh Ho river from the Pasut coast (Indonesian ocean) to the slopes of Mount Batukaru ± 75 km. Water treatment consisted of irrigation continuously, irrigation ago 4 days and irrigation intermittent 8 days. In order to obtain three water balance models in each part of the region are as follows: 1). I + Ch = P + Pt + P 1 + C; 2). I + Ch = P + Pt + P 2 + C; and 3). I + Ch = P + Pt + P 3 + C. Where: I = Irrigation (measured and observed was shallow ground water), Ch = Rainfall, P = Evaporation, Pt = tillage, P 1 = Irrigation continuously, P 2 = Irrigation 4 days and P 3 = Irrigation once every 8 days and C = Reserve. Results of the research showed that water supply in the watershed Yeh Ho with continuous irrigation, water used of 28,700 m ha leaving water reserves 62,700 m ha. Irrigation once every 4 days drains 25,200 m ha of waterleaving 66,100 m ha of water reserves and 8 days of irrigation consumes 22,100 m ha leaving 69,200 m ha of water . The observations showed that with continuous irrigation leaving 4.0% water, once every 4 days irrigation 15%, once every 8 days irrigation 46.3%. The availability of water and its dwastribution was increasingly limited, so the use of water for agricultural irrigation especially paddy rice needs to be done wwasely so that excess irrigation water can be used to generate income through other businesses that mutually support the agricultural sector.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123395364","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}

Therefore, SAPs have been predominantly used in agricultural industry in recent past. The present experiment was conducted to assess the effects of different watering intervals on growth of Abelmoschus esculentus established in a potting media with SAP developed in Sri Lanka (SLSAP) as alayerat the root zone. Abelmoschus esculentus plants were established in pots added with potting mixture; sand, compost, top soil and burned paddy husk in the ratio of 1:1:1: ½ and the top layered with SLSAP as the middle, with moist coir dust layers from top and bottom. At 3, 5 and 7 days’ intervals watered while maintaining the control at 3 days watering without adding SLSAP.Yield, plant height, numbers of flowers per plant, leaf area, moisture content in whole plant and relative humidity of plant leaves were measured. Except plant height, dates of watering were significant for all other measured parameter (P < 0.05). Also, watering at a 3 days’ interval resulted in a good yield from Abelmoschus esculentus , prepared SLSAP added layer wise growth medium compared to plants grown in 3 days watering in control medium. Plants watered once in 7 days were observed to be wilted. However, adding water revived them showing no permanent wiling. Further, when frequency of watering was decreased from once in 3 days to 5 days and 7 days, growth parameters were reduced by certain percent.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126237930","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}

A total of 20 upland genotypes including one check were used in the study. The trial was laid out in randomized complete block design with three replications with plot size of 6.0 m 2 . The combined analysis of variance revealed significant difference on days to maturity, panicle length, plant height, fertile tiller per plant and grain yield (P≤0.01). G7 (IR 83384-B-B-102-3) was the highest yielding genotype followed by G3 (IR 78937-B-20-B-B-4) and G5 (IR 83750-B-B-131-1) with grain yield of 4223.4, 3849.7 and 3776.3 kgha -1 , respectively. The GGE bi-plot graphic analysis revealed that the two principal components explained 76.42 % of the total GEI variance. GGE bi-plot analysis showed that G7 performed best in almost all environments except in E3 and E11. Grain yield performance and stability analysis revealed that G7 was the highest yielding and relatively stable. Therefore G7 was identified as candidate variety and it was verified along with the check on farmer’s field and on station.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116081386","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}
