The results showed that the mulching treatment by direct seed- ing, the mulching treatment by transplanting, and the exposed treatment by trans- planting performed excellently in bringing seedling stage forward, improving germina- tion rate, yield and quality. For example, seedling emergence stages were 36, 31 and 31 d earlier; germination rates improved by 19.24%, 14.29% and 14.29%; yields grew by 41.98%, 26.72% and 11.45%; starch contents increased by 3.50%, 2.10% and 1.40%, respectively. Therefore, cassava in the mulching treatment by direct seeding is characterized by earlier seedling emergence stage, high germination rate, high yield and quality.展开更多

It was exam-ined and approved by Henan Provincial Crop Variety Approval Committee in 2016 （Yushenmian 2016002）. In order to study the variety characteristics of ＇Yumian 50＇ and the key points of its cultivation technology and accelerate its application in cot-ton production, the breeding process of ＇Yumian 50＇ was described in this paper. The test data of 26 times for 3 years of ＇Yumian 50＇ participating in Henan region-al tests in 2012-2014 were summarized. The results showed that ＇Yumian 50＇ had outstanding performance in Henan regional tests and production tests. ＇Yumian 50＇ is a new cotton variety with characteristics of high yield, good quality and high re-sistance to diseases and pests.展开更多

[Method] In rainy season of 2012, high-yielding cultivation and fertilization technology of Lvhan No.l, a new cultivar of earlier ripe and drought resistant rice, was researched in CATETE farm of Luanda suburb with pot experiment method. [Result] In CATETE farm, Lvhan No.1 rice were directly sown in black clay and the rice can be significantly improved in plant height, grain weight of single plant, biological yield of single plant, ear length, total grain number per ear, number of filled grain per ear and thousand seed weight, as well as economic coefficient and ratio of grain to straw, if applied with base fertilizer made up of DAP （N：P2Os=14：43）, or compound fertilizer of N, P and K （N：P2Os：K^O=15：15：15） and with Duannai fertilizer and ear-grain fertilizer made up of urea. If DAP is taken as base fertilizer, the optimal quantity is 300 kg/hm2. If compound fertilizer of N, P and K is taken as base fertilizer, the optimal quantity is 450 kg/hm2, but urea at 75 kg/hm2 should be applied as Duannai fertilizer and ear- grain fertilizer, respectively, on time. [Conclusion] The research provides technical ref- erences for planting of Chinese rice cultivars in Angola.展开更多

As a result, output from crops is very low and thus, the rural areas suffer from food insecurity. This paper analyses food security status in the rural areas of Mizoram and suggests the measures to attain food security. A case study of 16 villages, lying in all the eight districts of Mizoram, was conducted in 2014 and 1527 households （76%） out of total 2010 households were surveyed through purposive random sampling method. Structured questionnaire was constructed and questions on three food security components and 13 indicators were asked. We used Z score technique to calculate data and finally got a composite score of all the components of food security. Our result shows that food availability in the study villages is very less as composite score stands for o.oo3 whereas food accessibility is comparatively higher, mainly due to availability of fair price shops （mean value is one）, high agricultural working population （40.1%） and high literacy rate （70.6%）. Therefore, its composite score is 0.236. Food stability scores only -0.062 and finally overall food security stands for 0.178, which is inadequate. We have suggested that‘system rice intensification＇, which is already in practice, should be given priority. Adequate irrigation facilities, proper public distribution system, cultivation of fruits and vegetables, value addition in farm products and access to market may achieve food security.展开更多

Today, consumer are increasingly aware of the quality of products, especially fresh food, but they have a little opportunity to choose the products which satisfy the needs, because they are limited to the product information and product origin. Fresh vegetables are one of the essential foods in the family living. The selection of fresh vegetables is not only to serve the basic needs as eating and drinking, but also to include the need for safety. Currently, consumer demand for fresh vegetable are great, especially when the living standards are becoming higher and people pay more attention to their health, especially for the consumer of Ho Chi Minh City. How fresh is vegetable market in Ho Chi Minh City today like.＇？ What is consumers＇ awareness of fresh vegetable？ What factors impact the fresh vegetable buying behavior of consumers？ Why does the development of fresh vegetable market in Ho Chi Minh City currently face many difficulties？ This study surveys the research, analyzes the factors affecting the economic area formation of fresh vegetable plantation at suburb of rio Chi Minh City.展开更多
