background and objectives: potato (solanum tuberosum l.) plant is one of leading agricultural products in the world. it is the fourth most cultivated food crop after wheat, rice and maize. planting density and weight of minituber are the factors influencing on the yield and yield components on seed tuber production in potato. plant density strongly affected yield, both by number and by weight a...
Abstract To find out how maize and potato can grow and develop in an intercropping system rather than each grown alone in a sole cropping system the following factorial experiment was performend in the frame-work of a randomized complete block three replications in the experimental farm of the faculty of agriculture, Zanjan University in year 2004. Different potato to maize ratios of (1:0), i...
Potato is one of the most important tuberous crops. To achieve optimum yield in potato, suitable brand and sufficient and balanced soil nutrients are necessary. In order to study the effects of Zinc, Manganese and Copper on potato yield and leaf and tuber concentrations of Phosphorus and Iron, a factorial pot experiment with 32 treatments was conducted in greenhouse of Soil Science Department, ...
بررسی عملکرد،اجزای عملکرد و شاخص های تحمل به تنش در ژنوتیپ های مختلف ارزن تحت رژیم های متفاوت آبیاری
با توجه به اینکه کمبود آب یکی از مهم ترین عوامل محدود کننده تولید محصولات زراعی در مناطق خشک و نیمه خشک می باشد لزوم شناسایی ارقام مقاوم به خشکی و همچنین معیارهای مناسب برای انتخاب این گونه ارقام ضروری است. لذا به منظور بررسی عملکرد، اجزاء عملکرد ژنوتیپ های مختلف ارزن و تعیین متحمل ترین ژنوتیپ براساس شاخص های تحمل به خشکی تحت رژیم های مختلف آبیاری آزمایشی به صورت کرت های خرد شده در قالب طرح بلو...
in a sustainable agriculture system, application of the fertilizers which are nature friendly and suitable for plants is essential. this becomes more important when dealing with medicinal plants. therefore, a factorial experiment in a randomized complete block design with three replications was set up in the 2012-2013 on nigella sativa l. treatments were nanofertilizer (pharmks®) (at 2 levels ...
This research was performed to study the effect of direct planting and transplanting of potato minituber on its yield and yield components. The experiment was designed as a randomized complete blocks with nine treatments and three replications. Treatments were one direct and eight indirect planting. In order to prepare the nursery, two types of pots (peat and nylon) and four types of substrates...
in order to investigate the effects of nitrogen fertilizer on yield and yield component of potato, (solanum tuberosum l.) and researching for direct and indirect effects of some important agronomic traits, an experiment was conducted based on randomized complete blocks design with three replications at the agricultural research station, ferdowsi university of mashhad, iran, during 2008. chlorop...
