Results on growing of climatic types of the pine in provenance trial plantations of Pavlodarskaya, East-Kazakhstan, Kostanayskaya and Akmolinskaya oblasts of the Republic of Kazakhstan are given. Long-term studies have shown that at growing of different origins in determined conditions with the use of identical agricultural techniques, different silvicultural, selection and economic effects are reached. Analysis of all the available material has been conducted on the basis of which new forest seed zoning is designed and the most productive and stable ecotypes are selected as candidates for sort-populations. Arakaragayskiy ecotype is universal for different zones and site conditions of the pine in Kazakhstan. Chebarkulskiy ecotype has good indices on productivity, stability, quality of plantings and on selection effect. Given geographical ecotypes are recommended as candidates for sort-populations. 展开更多

Bhutanese maize farmers grow different open-pollinated traditional varieties and improved high yielding varieties recommended by the national maize program. All most every maize farmer uses the recycled seeds from their farms for planting in the next season. Farmers traditional or informal seed system was found to be poorly organized and unscientific that has resulted in the deterioration and contamination of seed quality. Bhutanese maize farmers living in remote areas are highly constrained by the inconsistent supply and poor access to good quality maize seed. The formal public seed sectors lack adequate resources to produce and supply good quality seeds. This called for an urgency to identify and adapt an innovative and a sustainable seed production approach to service the subsistence needs of Bhutanese farmers in a cross-pollinated crop, like maize. The community based seed production (CBSP) approach was introduced and evaluated under the Bhutanese maize production system as an alternative farmer based seed production model. A total of seven farmers CBSP groups were formed and promoted as a smallholder seed enterprise. The technical skills of these CBSP group members on maize seed production were improved through practical demonstrations and trainings. The CBSP groups were supplied with high quality source seed of new maize varieties by the national maize program. For long term, the sustainability of CBSP groups were linked to the formal seed sector in the country for marketing the seeds. The CBSP approach has proven to be a successful small scale maize seed production model under highland maize production ecosystem that has improved the production and supply of good quality maize seeds. The Bhutanese experiences with CBSP in maize, its merits for small holder Bhutanese maize farmers and lessons learnt from the CBSP model are discussed in this paper. 展开更多

Handicrafts and furniture of bamboo once flourished in Taiwan during the 1970s and 80s but have since gradually declined after that period of time. The viability of the handicrafts industry was greatly threatened along with there being a real possibility of losing this traditional heritage. Nowadays, green products are a growing trend in the fashion industry, and thus some Asian countries have realized the importance of using green products and its development of cultural creative assets. The literature/study of the styles of traditional Taiwan bamboo arts are rare but they are worth exploring. Therefore, the purposes of this study are as follows: (1) to explore the category of traditional Taiwan Residents bamboo column furniture; and (2) to explore the backgrounds, forms, and contents of traditional Taiwan Residents bamboo column furniture. The results show that: (1) traditional Taiwan Residents bamboo chairs can be divided into eight categories: stool, side chair, slant-back reclining chair, tai-shi armchair, pair of gong-po chairs, two-seat chairs, "mother & child" chairs, and other styles of chairs; and (2) traditional Taiwan Residents bamboo column chairs styles originate from early Chinese Fujian and Guangdong provinces, and these bamboo chairs' forms have imitated the wood furniture of the Ming and Qing dynasty furniture. However, the technology of the enclosed-pipe structure is a special handicraft skill that reflects the early Taiwan Residents' resourcefulness in farming and fishing. We hope this paper can promote relevant and practical foundation research and studies. 展开更多

Understanding the relations and interactions between ecosystem components and plants is crucial for sustainable production of medicinal plants. To study the effect of simultaneous application of organic and biological fertilizers on yield and yield components of zucchini squash, split plot arrangement of factors based on randomized complete block design with three replications were used during 2009-2010 growing season. The mainplot factors were the type of organic fertilizers, including: (1) cow manure; (2) sheep manure; (3) chicken manure; (4) vermicompost; and (5) control. The subplot factors were the biofertilizes (Nitragin, containing Azotobacter sp., Azospirillum sp. and Pseudomonas sp.) utilization. The results showed the positive but non-significant effect of organic and biological fertilizers on yield and yield components of zucchini squash. Amongst the organic fertilizers, cow and chicken manure, have superiority compared to others. The highest seed oil and protein percent was obtained with application of chicken manure, however there was no significant difference between treatments in seed oil percent. The positive effect of organic and biological fertilizers on seed yield was higher than fruit yield. At a glance, application of cow manure solely was better than its application with nitragin. Nitragin application has no significant effect on some traits when utilized with sheep manure and vermicompost. 展开更多

Soybean (Glycine max: Fabaceae) is a mycotrophic (mycorrhizal) crop grown commercially for human consumption. Seven different fertilizer mixtures, namely cow dung, coir dust, mush room medium waste, saw dust, compost, decaying leaves and field soil with standard dose of NPK (control) were used for this experiment. The variety used was PM 25. Soil microbial activity was measured using CO2 evolution method. The experiment was carried out as a complete randomized block design with five replicates at the rate of eight plants per replicate. Average number of leaves on 25-day and 45-day old plants, shoot-length, root-length, number of pods per plant, wet weight of pod per plant, dry weight of pod per plant, plant wet weight, plant dry weight and seed dry weight per pod were measured. All management practices were conducted according to recommendations of the Department of Agriculture from seed germination to harvesting. Data were analyzed using SAS program (9.1.3). Highest number of pods/plant (100, 124, 102, 106) and dry-seed-weight in g/plant (12, 14.8, 12, 12) were recorded in those grown in cow dung, compost, decaying leaves and inorganic mixture (control) whereas the lowest pod production (8.7 pods/plant) and seed dry weight (1.0 g/plant) was recorded in saw dust. Instead of inorganic fertilizer there is possibility to use organic potting mixtures like compost and decaying leaves which gave a significant difference in crop productivity as compared to other treatments. Significantly highest mean microbial activity was observed in potting media filled with coir dust. 展开更多
