Empirical results indicate that there exists two-way Granger causality between Shandong water conservancy infrastructure construction and Shandong agricultural economic growth.Therefore,water conservancy infrastructure construction has a significant influence on agricultural economic growth in Shandong.

The Effects of Cropping Methods on Growth, Crop Index and Yield Response to Water of Rice （Oryza sativa L.） in Rainfed Agriculture

In this study, four combinations of crops： rice （C）, rice-maize （MCSI）, rice-cassava （MCS2） and rice-maize-cassava （MCS3） with 3 m × 3 m each plots at two field areas--Saptosari and Tanjungsari were observed. Both field areas are located in Gunungkidul district, South-Central of Java Island, with that 93% at those areas are 185 m to 500 m above sea level and high proportion of multiple cropping systems （MCS）. The aim of this study was to investigate the effect of different cropping method on growth, crop index and yield response to water of rice in rainfed agriculture. Mathematical models were developed to describe rice growth. The rice height was followed monomolecular function and the number of tillers followed exponential polynomial function. Crop index was calculated from climate data during plant growth phase. And yield response to water was calculated from actual evapotranspiration （ETa） and the maximum evapotranspiration （ETm）. The results showed that the height of rice was not significantly different between each combination （P 〉 0.05）. Number of tillers was also not significant （P 〉 0.05）. However, monoculture treatment had more number of tillers than rice in MCS. Crop index of rice at Saptosari was higher than at Tanjungsari. Based on the calculation of evapotranspiration （ET）, water deficit at initial was less than at mid-season （ETa 〈 ETm） and affected water stress. Statistical analysis showed that cropping methods did not significantly affect rice growth and yield （P 〉 0.05）.

Analysis on Internal Growth Potential of Agriculture Under the Agricultural Structure Adjustment in Xinjiang

Agricultural structure adjustment has always been the important factors influencing Xinjiang agricultural internal income growth.On the basis of the planting scale,productivity and price in 2010,the paper measured the contributions made by agricultural structure adjustment to Xinjiang agricultural internal income growth through structural optimization.Linear programming model was established by Lingo software,to optimize the structure of planting,horticulture,animal husbandry in Xinjiang and analyze the internal agricultural income growth potential.After structure optimization,Xinjiang agricultural production value will reach 1231.44×108yuan and the farmers'income of production and management will reach 9851yuan.The greatest potential for Xinjiang agricultural internal income growth was husbandry accounting for 41.33% of the total production value.The next one was horticulture,whose share of the total production value has raised to 17.43% from 10%.Fruit industry and animal husbandry will become the pillars of future income growth.There are still some income growth spaces in Xinjiang internal agriculture though the agricultural structure adjustment.The agricultural production value will increase by 44.32%and farmers'production and management income will increase by 68.83%.That will be one of the most important ways to tap the future potential of agriculture internal income growth.

Agriculture Key to Nigeria’s Growth

THERE are two growing schools of thought when it comes to developing the agricultural sector of Africa, a continent which holds about 60 percent of global uncultivated land. Both have the same goal, to ensure that the small farmer is part of the sector＇s growth. The first, headed by the Africa Progress Panel （APP）, believes that the sector will succeed and grow if it is developed from the ground up - in other words by raising the productivity of small- holder farmers. This is particularly supported by Kofi Annan and requires government action.

Analysis of Factors Influencing the Growth of Export of Agricultural Products in Yunnan Province: An Empirical Study Based on CMS Model

Yunnan Province is the bridgehead for the opening of the southwest region in China,and the economic frontier of China-ASEAN economic cooperation,where the export of agricultural products plays an important role in promoting the openness of the southwest region and strengthening China-ASEAN economic cooperation.In this paper,we use CMS model to analyze causes of the increase in the exports of agricultural products in Yunnan Province during the period 2001-2010.It is found that the expanded import scale of agricultural products in the world,improvement in the export competitiveness of products and the adaption of product export structure to the changes in the structure of world import demand,are the main factors responsible for increase in the exports of agricultural products in Yunnan Province.In recent years, the improvement of competitiveness of the export of agricultural products becomes a key factor for the growth of the export of agricultural products in Yunnan Province.In terms of the products classified,strong export competitiveness has promoted the export of plant products,such as beverages and tobacco,while weak export competitiveness and unreasonable export structure has impeded the export of animal products,plant and animal oil and fat products.

Allelopathic effects of Lantana camara on germination and growth behavior of some agricultural crops in Bangladesh

An experiment was conducted to understand the growth inhibitory effects of aqueous extracts derived from Lantana camara L. （a globally recognized invasive alien weed） on six popular agricultural crops of Bangladesh. The test was conducted in sterilized petridishes with a photoperiod of 24 hours and an average temperature of 29℃. The effect of different concentrations ofL. camara leaf extracts were recorded and compared with control （i.e., distil water）. Result showed different concentrations of aqueous leaf extracts caused significant inhibitory effect on germination, root and shoot elongation and development of lateral roots of receptor crops. Bioassays also indicated that the inhibitory effect was proportional to the concentrations of the extracts and higher concentration had the stronger inhibitory effect whereas the lower concentration showed stimulatory effect in some cases. The inhibitory effect was much pronounced in root and lateral root development rather than shoot and germination.

Impact of Agricultural Modernization,Economic Growth and Industrialization on the International Competitiveness of Agricultural Products:Based on the Empirical Analysis of Cointegration and VEC Model

The expanded agricultural trade deficit in recent years has caused widespread concern about the international competitiveness of Chinese agricultural products.In this paper,guided by Michael Porter's diamond model theory,based on agricultural production and trade data in China and the world from 1986 to 2011,we use principal component analysis,cointegration and vector error correction model,to perform an empirical analysis of the impact of agricultural modernization,economic growth and industrialization on the international competitiveness of Chinese agricultural products.The results show that China's agricultural modernization is slow,the demand for agricultural products caused by economic growth is increased,and excessive rural labor transfer due to industrialization leads to decline in the international competitiveness of Chinese agricultural products.China should increase its efforts to promote the modernization of agriculture and level of industry nurturing agriculture;use WTO rules to create a good international and domestic environment for the development of China's agriculture and improvement of the international competitiveness of agricultural products;give full play to the role of demand in boosting the industrial upgrading of domestic agriculture.

On the agricultural growth and structural changes in Suzhou Wuxi Changzhou region

s—Suzhou Wuxi Changzhou Region (Su Xi Chang) is a famous prosperous agricultural region in China. Since the early 1980s agriculture in Su Xi Chang has got constant developed, but its growth rate is lower than the provincial average level of Jiangsu, and its structure has not changed much. Therefore it lost many in the position of agricultural areal division of labour within Jiangsu Province. The authors of this paper suggest that Su Xi Chang agriculture should perform multiple social, economic and ecological functions with the suburban and export oriented farming as the main development direction. It is also necessary to improve management and organization structure for enhancing Su Xi Chang agricultural vitality.

Influence of Agricultural Inputs on Growth and Yield of Jatropha curcas （L.） in Cameroon

A study was carried out in the Northern region of Cameroon to assess the influence of fertilizers （chemical fertilizer NPK （15-20-15 w/w/w） or cow dung） on the growth and yield ofJatropha curcas from four origins namely Cameroon, Senegal, Tanzania and Mozambique. The experimental design was factorial with 4 origins×3 fertilizers×8 month durations. After planting, growth parameters and dendrometric measurements were carried out monthly during eight months. Data were analyzed using a Statgraphics program and Duncan test. The results showed that plant of Tanzania and Mozambique origin had higher germination rate in field 75% and 69.5%, respectively. The survival rate of transplants was 100% for Cameroon origin and 98.48% for Senegal origin. NPK and cow dung significantly （P 〈 0.05） increased the growth parameters height, diameter, number of ramifications, leaves and fruits of Jatropha curcas. In addition Jatropha from Cameroon origin exhibited the highest growing conditions and high fruit yield, then highlighting its potential for the biofuel program of the country. But significant improvement needs to be done, particularly on the level of fertilizer needed.

Performance of a No-Till Vegetable Transplanter for Transplanting Thai Round Eggplant (Solanum melongena L.) in Conservation Agriculture

Vegetables are vital for human health and are consumed five days a week in Cambodia.However,the production cannot meet domestic demands due to labor-intensive farming and production costs related to soil tillage.Mechanization is needed along with soil quality and sustainability improvements by the adoption of CA(Conservation Agriculture).The research aimed to compare the performance of the no-till vegetable transplanter with punch-planter in CA and hand transplanting in CT(Conventional Tillage).The study was conducted at the Royal University of Agriculture,Cambodia,starting from January to September 2020,by firstly growing sunn hemp as a cover crop and then transplanting Thai round eggplant.A randomized complete block design was used with three treatments,replicated three times.Each plot was 2 m by 15 m,with 0.2-m row spacing.The results showed that the transplanter speed was 0.54 km􀁸h^-1,almost two times the speed of punch planter and 9 times the speed of hand transplanting.The highest working capacity was also achieved with the transplanter.However,different transplanting did not affect plant spacing,or plant density.Plant spacing was 1 m,and plant density varied from 10,300 to 11,500 plants􀁸ha-1.Plant growth and yield were also not influenced by the transplanter in CA,or hand transplanting in CT.Average fruit diameter,fruit weight,fruit number,and yield were 38 mm,31.4 g􀁸fruit-1,15.7 fruits􀁸plant-1 and 3.9 t􀁸ha-1,respectively.The maximum working area of the transplanter and its break-even area were 25.2 ha·y^-1 and 18.3 ha·y^-1,respectively.Using the no-till transplanter may save both time and labor,but its use in combination with CA was unlikely to affect plant growth and yield in the short term.
