Cotton is one of the most important fibre crops playing a key role in economic and social affairs of the world. Water is a critical factor which influences on growth and yield of the cotton crop. Scarcity of water has put tremendous pressure on scientists to introduce drought tolerant cotton varieties. This study was aimed to determine water stress effects on the growth and yield of cotton. The present study was carried out to examine the effect of number of irrigations on the growth and yield of cotton during 2014. The field trial was conducted at the Experimental Fields of agronomy Section, agriculture Research Institute, Tandojam, Pakistan. A three replicated Randomized Complete Block Design (RCBD) was employed to layout the experiment having plot size of 2.5 m × 5 m (12.5 m2). Four cotton varieties i.e. NIAB-78, Shahbaz-95, Sindh-1 and TH-224/87 were chosen for this study based on their frequent farmer usage. All the agronomic practices were performed according to standard procedures. Results showed that all the growth and yield components of cotton were significantly (P 0.05) affected by irrigation frequencies. The cotton crop irrigated six times at 21 days interval showed better results with 138.16 cm plant height, 1.45 monopodial branches per plant, 21.83 sympodial branches per plant, 44.58 bolls per plant, 33.86% G.O.T., and 26.97 mm staple length, 149.84 g seed cotton yield per plant and 2271.16 kg·ha-1 seed cotton yield. This study concluded that variety NIAB-78 showed superiority over Shahbaz-95, Sindh-1 and TH-224/87 in almost all the characters of economic importance, and the cotton crop received 6 irrigations at 21 days interval resulted in significantly economical overall performance as compared with 5 irrigations or 4 irrigations with higher seed cotton yield.

A study was conducted to describe the progression of bud dormancy in 1-year-old apple (Malus × domestica Borkh) shoots grown at two contrasting climatic conditions (Belgium, temperate and Ethiopia, tropics). The experiment was carried out on "Golden" and "Gala" cultivars for two consecutive years (2010/2011 and 2011/2012). Moreover, a validation experiment was conducted on "MM106" apple rootstock during 2010/2011 only in Ethiopia. Variations in inverse of time to 50% budburst were interpreted in terms of evolution of growth capacity of the buds. Despite differences observed with chilling accumulation later in winter or early in spring, depending on environments, depth of endodormancy intensity during winter can be summarized as follows: buds from pruned shoots were less endodormant than terminal buds of the intact shoots and terminal buds were more endodormant than the dormancy intensity of upper buds of the disbudded shoots, suggesting proximal buds can grow more readily than does terminal ones. Our results provide evidence for the existence of a considerably strong paradormancy inhibition by distal shoot parts and buds, which was more pronounced in Ethiopia than in Belgium, highlighting the importance of designing and applying appropriate pruning and dormancy avoidance strategies in mild-winter climates. Finally, as still there is knowledge gap on bud dormancy progression and its control mechanism especially under mild climates, our study highlights the need for further in-depth research using biological and biochemical tests.

In order to combat environmental pollution, China enacted the Environmental protection Tax Law in early 2018. Yet the impacts of the environmental tax on individual regions with different socioeconomic statuses, which are crucial for social justice and public acceptance, remain unclear. Based on a MultiRegional Input-Output(MRIO) table and a nationally regulated tax payment calculation method, this study analyzes the distributional impacts of an environmental tax based upon province’s consumption from both inter-provincial and rural-urban aspects. The national tax revenue based on the current levy mechanism is estimated to be only one seventh of the economic loss from premature mortality caused by ambient particulate matter(PM2.5). The taxation may slightly alleviate urban-rural inequality but may not be helpful with reducing inter-provincial inequality. We further analyze two alternative levy mechanisms. If each province imposes taxes to products it consumes(rather than produces, as in the current mechanism), with the tax rate linearly dependent on its per capita consumption expenditure, this would moderately increase the national tax revenue and significantly reduce inter-provincial *** better compensate for the economic costs of air pollution and reduce regional inequality, it would be beneficial to increase the tax rate nationwide and implement a levy mechanism based on provincially differentiated levels of consumption and economic status.

不同农业景观能够影响生态系统生物控害与授粉的服务与功能,但同时也可能影响害虫的种群密度。为了探明江西赣北地区不同农业景观背景下油菜潜叶蝇种群动态,应用广义线性模型分析了农业景观构成因子与油菜潜叶蝇种群数量的关系。结果表明:油菜初花期、盛花期和终花前期,不同样地之间油菜潜叶蝇种群发生趋势相似,在油菜盛花期潜叶蝇为害最重,但不同样地之间的潜叶蝇种群数量差异显著。区域范围农业景观构成因素对油菜花期潜叶蝇发生数量有显著影响。草地面积、森林面积与油菜潜叶蝇的种群数量呈显著正相关关系,耕地面积在中等范围尺度(1 000m半径)与油菜潜叶蝇发生数量负相关。研究结果表明高比例的作物生境反而有相对更低的油菜潜叶蝇种群。本研究内容可以为分析农业景观的生态服务功能提供研究案例,为不同生态农业区域油菜潜叶蝇种群防控提供参考资料。

To impel resource utilization of agricultural waste,four provinces and cities of southwest China were taken as research objects,to analyze yield change of typical agricultural waste in southwest China during 2010-2016,and resource amounts of typical agricultural crops straw and livestock and poultry waste and their nutrient contents in four provinces and cities of southwest China in 2016 were calculated. The results showed that resource amount of typical agricultural waste in southwest China overall showed a continuously increasing trend with the improvement of agricultural comprehensive productivity. Straw resource amount of agricultural crops was dominant by rice and corn,and they accounted for 61. 61% of total amount in southwest China. Livestock and poultry manure was dominant by cattle and pig excrement,and they accounted for 89. 59% of total in southwest China. Seen from distribution region,the resource amount sequence of typical agricultural waste in southwest China was Sichuan > Yunnan > Guizhou > Chongqing. N,POand KO in straw resource of typical agricultural crops in southwest China of 2016 were respectively 76. 11 ×10~4,23.36 ×10~4 and 125. 78 × 10~4 t,and total nutrient amount was 22. 53 × 10~5 t. N,POand KO of livestock and poultry manure resource were respectively 27. 28 × 10~4,12. 87 ×10~4 and 62. 45 × 10~4 t,and total nutrient amount was 10. 26 × 10~5 t. Therefore,resource amount of agricultural waste in southwest China is rich in a long term,and nutrient storage is huge. Its reasonable recycling is favorable for sustainable development of agriculture in southwest China,and has important actual significance for guaranteeing crop yield and decreasing chemical fertilizer use.

American Journal of Plant Sciences 2015年第2期6卷 298-305页

Zinc is the micronutrient that presents the greatest response in corn grain production. However, the mode of application and the dose used are decisive factors with respect to fertilizer efficiency in the crop. Thus, the objective of the present study was to evaluate the residual effect of zinc application methods and rates on corn nutrition and productivity. The experiment was conducted in the experimental area of the Teaching, Research and Production Farm of the FCAV/UNESP. Soil in the area is classified as dystrophic Dark-Red Latosol (dRL). The experimental setup consisted of a randomized complete block design with four replications. Treatments included three localized Zn doses applied to the soil (planting row);three Zn doses incorporated into the soil at depth of 0 - 20 cm;foliar application, seed application and treatment without addition of Zn. Two evaluations of growth during cultivation were performed. Grain productivity of the crop and the zinc content in soil, leaves and seeds were evaluated. Foliar spraying with Zn simultaneously promoted increased leaf Zn content and basal diameter of the plant. The Zn contents in grains and in the soil, as well as grain yield, were not affected by the Zn application methods or the applied doses. The residual effect of incorporated Zn doses was observed only in the basal diameter and number of leaves at 60 days after emergence.
