Bio-economic efficiency of different cotton-based intercropping systems was determined at the Agronomic Research Area, University of Agriculture, Faisalabad, (Pakistan) during 1996-97 and 1997-98. Cotton cultivar NIAB-78 was planted in 80-cm apart single rows and 120-cm spaced double row strips with the help of a single row hand drill. Intercropping systems were cotton alone, and cotton + mungb...
ارزیابی عملکرد اقتصادی و کارایی مصرف نور در کشت مخلوط و خالص ذرت و پنبه تحت تاثیر سطوح مختلف نیتروژن
In order to study the potential of maize-cotton intercropping for improving radiation use efficiency (RUE), an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications at experimental filed of Ferdowsi University of Mashhad. The experimental treatments were nitrogen in four levels (0, 50, 100 and 150 Kg N ha-1) and planting pattern ...
To study the effects of wheat-maize intercropping on the population dynamics of wheat aphids and their natural enemies, wheat-maize intercropping patterns were divided into four levels: 8:2, 6:2, and 4:2 intercropping, and monoculture wheat. The results showed that as the wheat coverage rate decreased, the quantities of immigrating winged aphids and their natural enemies significantly differed;...
A field experiment was conducted to evaluate the effect of planting pattern and irrigation system on antioxidant activity of wheat and Persian clover. The experiment was carried out as a two-factor factorial with three replications. The first factor was irrigation system (conventional and partial root-zone irrigation) and the second was planting pattern (sole wheat, sole Persian clover, alterna...
Of the several mechanisms that can bring about efficient resource use, the most widelyapplicable one is intercropping systems that can make better use of resources. The aim of thisstudy was to evaluate resource capture and resource use efficiency in transgenic cotton-peanutintercropping system and in their respective sole crops with using 25-50% substitution ofrecommended dose of nitrogen (RDN)...
To investigate the amount of nitrogen (N), phosphorous (P) and potassium (K) uptake in crops and weeds in cereals-legumes intercropping, a field experiment was performed in 2014-2015. Treatments included 10 monoculture (wheat, barley, triticale, pea and bean with and without weeds) and 6 intercropping (wheat + pea, wheat + faba bean, barley + pea, barley + faba bean, triticale + pea and tritica...
With increasing economic and environmental costs associated with fertilizer use, the need for low-input agroecological systems is on the rise. It is well documented that intercropping legumes can increase the supply of nutrients, through N2-fixation and P mobilization. Concurrently, the integration of trees in the agricultural landscape shows increasing evidence of nutrient inputs through effic...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
چکیده به منظور بررسی اثر تنوع گیاهی و نوع منبع تغذیه ای بر تنوع و تراکم علفهای هرز و حشرات، کارایی مصرف نهاده ها ( نور، آب، عناصر غذایی) و عملکرد و خصوصیات کیفی چند گونه زراعی، آزمایشی به صورت کرتهای خردشده بر پایه طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1385-1384 و 1386-1385 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد به اجرا درآمد. تیمارهای مورد بررسی دو منبع کود دامی و...
In order to determine the best intercropping combination of wheat (Triticum aestivum) and rapeseed (Brassica napus) based on total yield and landuse efficiency, an experiment was conducted during 2010-2011 growing season at Agricultural Research Farm of Faculty of Agriculture, Bu-Ali Sina University. This experiment used randomized complete blocks design and three replications. Treatments inclu...
