Improvement of resource use efficiency is a basic approach for sustainable agriculture. Applying intercropping systems, in which resources such as water, radiation and nutrients are used optimally, is one of these strategies. In order to evaluate radiation absorption and use efficiency in additive intercropping of maize-bean, an experiment was carried out in 2010, based on completely randomized...
this research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. to do this a split plot experiment carried out based randomized complete block design with three replications in research field of shushtar islamic azad university. the main plot included three level...
Intercropping is a labor-intensive practice largely adopted by smallholder farmers to increase yield per unit area, cope with crop failures and market fluctuations, meet food preferences farm income. A field experiment was conducted examine the performances intercropping efficiencies of sweet corn okra planted in young rubber plantation. The treatments were arranged Randomized Complete Block De...
in order to evaluate the yield and advantage of two- and three-species intercropping of sunflower with corn and soybean, an experiment was conducted at the research farm of faculty of agriculture of tabriz university in tabriz, iran 2011. the experiment was arranged based on randomized completely block design with 6 treatments and three replications. treatments were included the pure stand of s...
Reaction of the Green Bean- Safflower Intercropping Patterns to Different Nitrogen Fertilizer Levels
In order to investigate the effects of nitrogen fertilizer levels and intercropping ratios on yield and other morphological traits of two crops, field experiments were conducted during two years (2010-2011) in the research field of the school of Agriculture, Shiraz University, Shiraz, Iran. The study was carried out in a factorial experiment laid out based on a completely randomized block desig...
Neoplasm formation, a non-meristematic tissue growth on young field pea (Pisum sativum L.) pods is triggered in the absence of UV light and/or in response to oviposition by pea weevil (Bruchus pisorum L.). This trait is expressed in some genotypes [neoplastic (Np) genotypes] of P. sativum and has the capacity to obstruct pea weevil larval entry into developing seeds. In the present study, 26% o...
Competition indices used to evaluate the agronomic and monetary advantage in intercropping: A review
The official journal of Agricultural Sciences published by the Faculty Agriculture, Eastern University, Chenkalady, Sri Lanka.AGRIEAST publishes research information broad practical significance pertaining to both tropical and subtropical Agriculture.
introduction multiple cropping such as intercropping plays an important role in agriculture because of maximizing beneficial interactions. intercropping of legumes and cereals is an old practice in tropical agriculture that dates back to ancient civilization. maize-legume intercrops could substantially increase forage quantity and quality and decrease requirement for protein supplements (ahmad ...
Application of intercropping systems is one of the ecological methods for controlling weeds due to maximization of soil cover and plant diversity. In order to study the effect of intercropping system of indigo (Indigofera tinctoria L.) and roselle (Hibiscus sabdariffa L.) on biodiversity, weeds population changes and plant yield an experiment was conducted based on randomized complete block des...
