Deep tillage of compacted soils can improve potato (Solanum tuberosum L.) tuber yield and quality if no other production factors are limiting. We hypothesized that within-row subsoiling and N placement would affect tuber yields and availability of plant nutrients. Potato (cv. Russet Burbank) was grown after winter wheat (Triticum aestivum L.) in 1989 and after dry bean (Phaseolus vulgaris L.) i...
Sweet potato (Ipomoea batatas) is one of the stable tuber crops consumed by many households in Nigeria. It can be found in different varieties and exist in many colours of skin and flesh. The production of this important crop is still very low, thereby compromising food security. Sweet potato is one of the target commodity crops under the Nigerian Agriculture Sector Investment Opportun...

abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
Recent studies, including those from our laboratory, have provided evidence that by improving tuber Ca level we can reduce tuber internal defects and improve its storability. The purpose of the present study was to determine the influence of supplemental Ca fertilization on tuber size and tuber number. For this purpose, plantlets of Solanum tuberosum cv Russet Burbank raised in tissue culture w...
چکیده: در این تحقیق تأثیر ملاس که یکی از محصولات جانبی صنایع قند می باشد به عنوان یک افزودنی مقاومت خشک جدید در بهبود پالایش پذیری و ویژگی های فیزیکی و مکانیکی مقوای کنگره ای کهنه (occ) مورد بررسی قرار گرفته شد. بدین منظور پنج سطح ملاس( 0،5، 10، 15 و 18%) و سه سطح درجه روانی(420،400و320 میلی لیتر)به عنوان فاکتورهای متغیر در نظر گرفته شد و برای هر تیمار کاغذهای دست ساز با مساحت 2cm200 و وزن پای...
With rising environmental concerns for current practices of fertilizer N management in the humid and cool areas, we simulated soil N dynamics and plant N use in the potato (Solanum tuberosum L.) cropping system using the software Stella. The objectives were to predict inseason N requirements by the potato crop, tuber yield, N uptake, N partitioning within root, leaf, stem and tuber, and N loss ...
To achieve the high level of gene expression, promoters are key elements. Patatin promoter has been used as a specific gene expression in potato tubers. Patatin is a group of glycol protein in potato tuber which is code by a multiple family genes. This protein makes up more than 40% of soluble proteins of potato tubers. Class I Promoters mainly responsible for tuber -specific expression patte...
according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
