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.e...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
abstract in order to study of chemical and mechanical weed management methods and their integration in potato (solanum tuberosum), a field experiment was done in 2008 at ferdowsi university of mashhad research field. experimental design was completely randomize block design with 6 treatments and 3 replications. treatment included broadcast herbicide application (standard treatment), between row...
Strategies to enhance local adaptation capacity are needed to mitigate climate change impacts and to maintain regional stability of food production. The objectives of this study were to simulate the climate change effects on phenology stages, potato production in the future and to explore the possibilities of employing planting dates and various varieties (Agria, Arinda and Santeh) as mitigatin...
the aim of this study was to investigate the effects of winter crops residues on weed control, physiological indices, yield and yield components of potato. an experiment was carried out at the research farm of colleg of agricultural of bu-ali sina university in 2009. the experiment was a randomized complete block design with three replications. residues of rye, oilseed rape, triticale, barley, ...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
to determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in ardebil agricultural research station for two years (2001 and 2002). the experiment was in a split split splot on the basis of completely randomized block design with three replications. pre-germination and non pre-germin...
Rapid expansion of the processing potato industry has contributed to a significant increase in irrigated potato production in Manitoba. However, information is lacking regarding optimum rotations for local conditions. In 1998, a crop rotation study was initiated on a Wellwood silt loam near Carberry to identify crop rotations that optimized crop yield and quality while maintaining soil quality....
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...
Potato has become one of the primary cash crops in the arid region of the Loess Plateau. However, what and how cereal crops to rotate with potato is better for the farmer’s income and environment is unclear now. 11 potato based rotation systems were simulated in Yulin, using EPIC model based on local information. Results showed 1) Though mean potato yield decreased from 6.84 to 5.38 t/hm, the m...
