Jordanian Horticultural Export Competitiveness from Water Perspective

The main objective of this paper is to analyze the relationships between the productive process and the commercial trade with water resources used by them. For that the goal is to find out, by means of the estimation of water embodied in the exported crops which have the highest export competitiveness and lower water consumption. The finding contradicts not only the comparative advantages theory but also the resources sustainability logic. This conclusion is derived from the great exports of water via tomatoes and low profitable vegetables from producers＇ perspective but not economical from social perspectives as shown in domestic resource coefficient. The diversion between financial and economic profitability is due to heavily irrigation water subsidy. The results confirm that Jordan utilizes large amounts of water in its exports, and in turn, it does not export goods with low water requirements. The potential saving would be very significant and agricultural sector need to modify the use of water to a great extent in order to reach significant water savings and an environmental sustainability. Jordan has to implement policies that reduced, or even abandoned, the export and the production of water-intensive crops. Therefore, they have to be replaced with either imports or crops that optimize the water resources.

Factorial analysis of the effect of sugarbeet vinasses on agroecological indices in horticultural field

The impact on soil of applying sugarbeet vinasses （V） was analyzed through a field experiment in horticulture greenhouse, arranged in a 23 factorial design. Two levels of three independent variables--application of V, use of polyethylene cover （PC） on the soil. and soil depth （D）---on various dependent variables were studied. Vinasses favoured crop yield and reduced the number of Meloidogyne incognita juveniles in soil. The concentrations ofN. P and K increased with the interaction VxD, with PC also increasing N concentration. The amounts of humic acids and humin decreased with D; fulvic acid concentration increased with V, but decreased with the interaction VxPC. Soil physical factors were improved mainly with D and V. Aromaticity of humic acid-like fractions increased ~＇itb V. In general, V showed significant effects mainly on the topsoil, suggesting low leaching risks. The results indicate that the levels of the independent factors improving a group of variables were not the same that those contributing to another group. Therefore, their best combination should be determined for each scenario to achieve optimum agroecological performance.

Observation on fitting male selections of different kiwifruit varieties

Five male kiwifruit selections Truwind M1, M2, M3, M4 and M5 bred by Hunan Horticultural Research Institute (HHRI)have been observed on the suitability,of which Truwind M1,M2 and M3 are Actinidia chinensis,Truwind M4 and M5 are Actinidia deliciosa. In terms of flower period Truwind M1 is early and 7 days, which is the suitable pollinator for‘Fengyue’;Truwind M2 is intermediate with 15 days,suitable for ‘Kuimi’and‘Lushanxiang’;Truwind M3 and M4 are 14 days and 13 days respectively,suitable for‘Cuiyu’and‘Miliang 1’;Truwind M5 is late and 8 days, suitable for‘Jinkui’,‘Qinxiang’and‘Hayward’.

Research on Gardening Status and Development Prospect of China Facilities Horticulture

Horticulture refers to the producing of horticultural plants in unsuitable season （cold or hot）, the use of keeping heat, preventing cold or keeping cool, rain facilities and equipment, to artificially create a suitable micro climate horticultural crop growth environment, not or less affected by natural seasons conduct horticultural crop production, which is known as horticulture. It Simply covers facilities include a variety of hotbed, cooling bed, a small shed, shade avoidance, shade, shade cover, etc.; ordinary protection facilities usually refers to plastic greenhouses, plastic shed and Greenhouse; modem greenhouse, usually refers to capable of temperature and humidity, environmental conditions, fertilizer, gas and other automatic control of single buildings or greenhouse.

Vertical Zonation of Horticultural Farming in the Alaknanda Basin of Garhwal Himalaya, India

Horticultural practice in the Himalayas has great importance not only for economic development but also for environmental restoration. In the entire Himalayan mountain system, from Jammu and Kashmir Himalaya to Assam Himalaya, the practice of horticulture is centuries old, which includes varieties of fruits along with availability of high quality and quantity. In terms of the Alaknanda Basin, which is centrally located in the Himalayan system, the practice of horticulture does not get commercial level; only it is cultivated domestically. The climatic conditions ranging from sub-tropical (low-lying river valleys) to alpine and frigid (highly elevated regions) are suited for varieties of fruit cultivation, yet the benefit of this could not be utilized by the residents who are working in the agricultural fields. Besides, less proportion of land is devoted for fruit cultivation along with domestic production of fruits. The varieties of fruit cultivated in the basin range from mango-guava-papaya, stone-net, citrus to apple at the different elevations. Along with the cultivated fruits, varieties of wild fruits are also found in the jungle. There are four climatic zones suitable for the production of various fruits as below:? Sub-tropical zone including the lower part of the Alaknanda, Pindar, Nandakini, and Mandakini rivers is suitable for mango, guava, and papaya; ? Sub-temperate zone in the middle basin of the Alaknanda, Pindar, Nandakini and Mandakini rivers is a good place for citrus fruits, particularly orange and lemon; ? Temperate zone occupying the Dauli, Vishnu Ganga, Upper Pinder, Nandakini and Mandakini rivers is highly productive for apple, nut and stone fruits; ? Alpine meadows in the highly elevated region are known as Bugyal famous for herb culture. Each of these zones has distinct physical features, environmental conditions and socio-economic identity for fruit cultivation. The present paper aims to discuss about the vertical zonation of the horticultural farming and its nature, in terms of development, in the Alaknada Basin.

Use of Waste Vegetable Biomasses Treated by Steam Explosion for the Horticultural Crop Protection

The purpose of this study was to assess the suppressive effect of Waste Vegetable Biomasses （WVBs） treated by the Steam Explosion technique in a continuous plant, against soil-borne plant pathogens. In order to assess their disease suppression, five WVBs （Miscanthus biomass, durum wheat straw, rice straw, corn stalk and wood shaving） and commercial compost were tested in vivo at three different doses （10, 20 and 30% of potting mix） on seven horticultural pathosystems plant/fungus： tomato/Phytophthora nicotianae, cucumber/Pythium ultimum, lettuce/Fusariurn oxysporum f. sp. lactucae, melordFusariurn oxysporum f. sp. melonis, bearffRhizoctonia solani, eggplant/Verticillium dahlie and fennel/Sclerotinia sclerotiorum. The results showed that the corn stalk was more efficient respect to Miscanthus, compost, wheat straw, rice straw and wood shaving in all the patbosystems and at all the doses tested. The corn stalk suppression ranged from 97% in eggplant/F, dahliae to 35% in lettuce/F, oxysporum f. sp. lactucae, and it was significantly higher with respect to the other substrates. In general, the wheat straw, rice straw and wood shaving were statistically found less efficient as suppressive substrate with respect to corn stalk, Miscanthus and compost at the 30% dose in four pathosystems In particular, the wood shaving suppressiveness ranged from 48% in eggplant/V, dahliae to 12% in lettuce/F, oxysporum f. sp. lactucae. The different suppressiveness observed could be attributed to different concentration of the microbial inhibitory substances （furfurals, organic acids and lignosulfonates） produced during the processing of fresh biomass.
