Current Status of Rice Production in Burundi and Its Development Strategies

Burundi, a landlocked country locked near the equator, is one of the least developed countries confirmed by the United Nations and the 60% financial revenue needs aid. Rice is the most important and extravagant food in Burundian consumption for no more than 5 kg on average per people by year. It＇s especially suitable to plant rice in Burundi because of the sufficient sunlight and rain. But the lack of new varieties, practical technology and modern service make it very difficult for rice production. According to this significant roll, the rice production has to be increased in order to satisfy the consumption needs which are now becoming higher and keep the food safe. This article mainly shows the rice ecological types, production facts and the major constraints of rice production in Burundi, and then look into the distance on how to solve the problems.

Evaluation of CMPAS precipitation products over Sichuan,China

High-quality and high-resolution precipitation data are the basis for mesoscale numerical weather forecasting,model verification,and hydrological monitoring,which play an important role in meteorological and hydrological disaster prevention and mitigation.In this study,high-density rain gauge data are used to evaluate the fusion accuracy of the China Meteorological Administration Multisource Precipitation Analysis System(CMPAS),and four CMPAS products with different spatial and temporal resolution and different data sources are compared,to derive the applicability of CMPAS.Results show that all the CMPAS products show high accuracy in the Sichuan Basin,followed by Panxi Area and the western Sichuan Plateau.The errors of the four products all rise with the increase in precipitation.CMPAS overestimates precipitation in summer and autumn and underestimates it in spring and winter.Overall,the applicability of these fused data in the Sichuan Basin is quite good.Due to the lack of observations and the influence of the terrain and meteorological conditions,the evaluation of CMPAS in the plateau area needs further analysis.

Effect of potassium on soil conservation and productivity of maize/cowpea based crop rotations in the north-west Indian Himalayas

Plots under conservation tillage may require higher amount of potassium(K) application for augmenting productivity due to its stratification in upper soil layers, thereby reducing K supplying capacity in a medium or long-term period. To test this hypothesis, a field experiment was performed in 2002-2003 and 2006-2007 to study the effect of K and several crop rotations on yield, water productivity, carbon sequestration, grain quality, soil K status and economic benefits derived in maize(Zea mays L)/cowpea(Vigna sinensis L.) based cropping system under minimum tillage(MT). All crops recorded higher grain yield with a higher dose of K(120 kg K2 O ha-1) than recommended K(40 kg K2 O ha-1). The five years' average yield data showed that higher K application(120 kg K2 O ha-1) produced 16.4%(P<0.05)more maize equivalent yield. Cowpea based rotation yielded 14.2%(P<0.05) higher production than maize based rotation. The maximum enhancement was found in cowpea-mustard rotation. Relationship between yield and sustainable indices revealed that only agronomic efficiency of fertilizer input was significantly correlated with yield. Similarly, higherdoses of K application not only increased the water use efficiency(WUE) of all crops, but also reduced runoff and soil loss by 16.5% and 15.8% under maize and 23.3% and 19.7% under cowpea cover, respectively. This study also revealed that on an average 16.5% of left over carbon input contributed to soil organic carbon(SOC). Here, cowpea based rotation with the higher K application increased carbon sequestration in soil. Potassium fertilization also significantly improved the nutritional value of harvested grain by increasing the protein content for maize(by 9.5%) and cowpea(by 10.6%). The oil content in mustard increased by 5.0% and 6.0% after maize and cowpea, respectively. Net return also increased with the application of the higher K than recommended K and the trend was similar to yield. Hence, the present study demonstrated the potential yield and profit gains along with resource conservation in the Indian Himalayas due to annual additions of higher amount of K than the recommended dose. The impact of high K application was maximum in the cowpea-mustard rotation.

Nutritional evaluation of caseins and whey proteins and their hydrolysates from Protamex

Whey protein concentrate (WPC 80) and sodium caseinate were hydrolyzed by Protamex to 5%, 10%, 15%, and 20% degree of hydrolysis (DH). WPC 80, sodium caseinate and their hydrolysates were then analyzed, compared and evaluated for their nutritional qualities. Their chemical composition, protein solubility, amino acid composition, essential amino acid index (EAA index), biological value (BV), nutritional index (NI), chemical score, enzymic protein efficiency ratio (E-PER) and in vitro protein digestibility (IVPD) were determined. The results indicated that the enzymatic hydrolysis of WPC 80 and sodium caseinate by Protamex improved the solubility and IVPD of their hydrolysates. WPC 80, sodium caseinate and their hydrolysates were high-quality proteins and had a surplus of essential amino acids compared with the FAO/WHO/UNU (1985) reference standard. The nutritive value of WPC 80 and its hydrolysates was superior to that of sodium caseinate and its hydrolysates as indicated by some nutritional parameters such as the amino acid composition, chemical score, EAA index and predicted BV. However, the E-PER was lower for the WPC hydrolysates as compared to unhydrolyzed WPC 80 but sodium caseinate and its hydrolysates did not differ significantly. The nutritional qualities of WPC 80, sodium caseinate and their hydrolysates were good and make them appropriate for food formulations or as nutritional supplements.

Effect of Enriched Cattle Manure on Soil Nutrient Status, Nitrogen Uptake and Yield of Tea （Camellia sinensis）

Inorganic fertilizer NPK （nitrogen, phosphorus and potassium） （S） 25：5：5：5 is generally recommended for optimum yield and quality of tea （Camellia sinensis）. Non-judicious use of this inorganic fertilizer however acidifies the soils and pollutes the environment. Integrated soil fertility management （ISFM） which involves the combined use of organic and inorganic fertilizer is recommended for improved crop yield and soil health. An experiment was carried out to determine the effect of enriching cattle manure with different ratios of inorganic fertilizers （OM： NPKS at ratios 1：2 and 1：4）, and rates on soil nutrient status, nitrogen uptake and yield of tea in the east of Rift Valley, Kenya. Enriching manures and organic manure up to a rate of 150 kg N/ha increased the level of P mature leaf. A higher N and K level in the mature leaf was observed when NPKS was applied at higher rates. In the soil, fertilizer rate up to 150 kg N/ha showed higher pH and K where organic manure and enriched manures were applied while NPKS treatment showed higher P content throughout the soil depths. Enriching organic manures with inorganic fertilizers increased yield significantly.

Effect of new specific fertilizer on the growth of peanut

Based on the soil nutrient condition of Fujian province and the nutritional characteristic of peanut, new specific peanut fertilizer was made with some new types of synergists and chemical fertilizers. In 2005, a field experiment was conducted to study the effect of the new specific fertilizer on peanut at Gaobi town, Longyan city, Fujian province. The results showed that, the new specific fertilizer could relieve the inhibition of fertilizers on nodule formation of peanut, promote the growth of peanut plants, increase the yield of peanut and improve the utilization rate of fertilizer, contrasted to common fertilizers. To compare with one time application of common fertilizers, the new specific fertilizer which was applied one time and twice had significant positive influences on yield of peanut and nutrient use efficiency, increased economic yield of peanut by 3.8% and 6.3%; improved nitrogen, phosphorus and potassium use efficiency by 3.9, 2.8, 4.3 and 4.5, 5.7, 7.4 percentage points respectively. Compared with twice applications of common fertilizers, the new specific fertilizer which was applied as the method above increased economic yield of peanut by 0.7% and 3.2%; improved nitrogen, phosphorus and potassium use efficiency by 0.3, 1.6, 0.5 and 0.9 4.5, 3.6 percentage points respectively.

Chinese Brands at the Crossroad？ Demand State in Kerala Markets

Globalization and liberalization offer competitive openings for several world brands to the Indian markets. Bestowed with growing disposable incomes, Kerala consumers exhibit wide diversity in their buying habits. Apparently, the emerging fascination for imported brands impels distributers to leave enough space to shelf more ＂made in China＂ brands in their showrooms. The substantial increase in consumers＇ demand for imported goods with considerable attraction for ＂made in China＂ products inspired this study to explore the demand state for various types of Chinese products in the Indian regional markets. Divided into two stages, at first, with a primary survey, the study explores the consumers＇ perception towards selected five vastly available consumer durables such as electrical appliances, handicrafts, stationeries, toys and builds wares. Later, the demand matrix developed from the primary data defines the types of demand prevailing for each category of＂made in China＂ products based on their popularity and consumption in Kerala markets.

Borderline Products between Bio-fertilizers/ Bio-effectors and Plant Protectants： The Role of Microbial Consortia

In the delicate normative balance, at European Union （EU） level of the borderline products （i.e., between plant protectants and bio-fertilizers/bio-effectors） containing microbial consortia （MC） instead of single microbial strains, the most relevant factors influencing the categorization of the products are the intention of use, the cell density and the mode of action. For the latter, the basic difference between the two types of products is that a plant protectant has a targeted activity on plant pathogens, while a bio-fertilizer acts indirectly by nourishing and fortifying the host plant （healthier plant）, thus inducing a generalized resistance to the onset of pathological status, irrespective of its origin and nature. Case-studies are presented on the effectiveness of MC as bio-fertilizers/bio-effectors on different crops. Bio-fertilizers exhibit a double effect--biotic and abiotic, leading to the fortification of the crop plant linked to its more effective water and nutrient uptakes as well asto a generalized healthier status. This in turn leads to a higher resistance to diseases. In addition, bio-fertilizers play a relevant role on the reduction of environmental impacts due to chemical fertilizers, e.g., by facilitating the uptake of phosphorus （P）, thus reducing the need of P fertilization. Although finding a scientifically-based balance between regulatory need and marketing constraint is not always an easy task, the availability of scientific advancements combined to common sense should help in describing positive effects and risk profiles of MC in agriculture.

Analysis of China's Oil Imports and Exports Situation

China＇s oil import dependence had risen to 72% in 2017, while its net imports of various oil products, including crude oil, refined oil, liquefied petroleum gas （LPG） and other products, had climbed to 418.8 million tons, an increase by10.7% over 2016. China＇s crude oil import reached 420 million tons, surpassed the United States for the first time, and China had become the biggest crude oil importing country in the world. Net export of the rejqned oil, mainly the diesel, continued to increase to 22.7 million tons, as driven by the oversupply situation of the domestic market. Last year, China＇s LPG import was 18.45 million tons, but its growth was diminishing. Oil price would continue to rise in 2018, while the domestic demand of refined oil would be maintained at a lower rate of growth. However, driving by new refining capacities to be brought online, it is estimated that the crude oil import would still be increased remarkably. LPG import would reach a new high due to the growth potential and strong demand for feedstocks in the petrochemical product market.

The Requirements for the Development of Small and Medium Enterprises in Croatia and the European Union

Small and medium enterprises are the main institutional medium of the European economy. This is also recognized by the government of the Republic of Croatia, which emphasizes their importance and values their dynamism and capability for revitalizing the Croatian economy, and supports this by ways of subsidies. But, for all the effort, the economic position of small and medium enterprises in the terms of globalization is becoming more complex and uncertain, limited by time and more demanding. This does not correspond with the thesis which states that in the environment and conditions of the modem market economy, which is dynamised by progress in science, technology, information and communication, entrepreneurship has manifested a progressive dimension with the character and needs of all economic activity, as well as a tendency to achieve set objectives and generate change. Recently, after the repeated recession, which was encumbered by the effects of the one before, the conditions of doing business and survival for small and medium enterprises have changed significantly in a negative sense. So, there is a justified cause for questioning earlier stances about small and medium enterprises and their capability to be a motor of development of the Croatian economy, as well as to reevaluate their influence in the context of GDP growth, to focus on the importance and prevalence of certain sectors of the economy, to critically evaluate economic measures which do not lead to a reduction in unemployment and to define the requirements for future development of the small and medium enterprises, which implicates the increased economic efficiency, quality and living standards.
