in order to study crop rotation, chemical control and their interactions on weeds density of wheat fields, an experiment was conducted in a split plot arrangement in randomized complete block design with three replications in gorgan agricultural research station for five years. in this study, 10 rotational crops: canola, fababean, barley, white pea, soybean, cotton, maize, sorghum, millet and w...

Intercropping is an old and commonly used agricultural practice involves the cultivation of two or more crops in same area land at time may improve yield, use environmental resources, product quality, soil health. The objective present study was to effect water availability wheat-pea intercrops using agronomic physiological characteristics. experiment conducted farm Aristotle University Thessal...

Intercropping has a strong potential to counteract the severe degradation of arable land in the North China Plain (NCP). However, a rapid decline of intercropping can be observed in the last decades. The present paper investigates the reason for this development and suggests solutions on how to adjust intercropping systems to fit modern agriculture. Firstly, the developments of socioeconomic co...

Objective: For investigation of intercropping of maize and faba bean, an experiment was conducted in Research Station of Agriculture Faculty of Tabriz University during growing season of 2013. Methods: Experimental design was randomized complete block design with three replications and seven treatment. Treatments included one row intercropping (1:1), 4 strip intercropping pattern with ratios of...

BACKGROUND Intercropping systems could increase crop diversity and avoid vulnerability to biotic stresses. Most studies have shown that intercropping can provide relief to crops against wind-dispersed pathogens. However, there was limited data on how the practice of intercropping help crops against soil-borne Phytophthora disease. PRINCIPAL FINDINGS Compared to pepper monoculture, a large sca...

In order to combat adverse effects of farmland degradation it is necessary for farmers to adopt sustainable land management and conservation strategies like intercropping and conservation tillage. However, efforts to adopt these strategies are very minimal in Ethiopia. In an attempt to address the objectives of examining factors affecting use of intercropping and conservation tillage practices,...

It is well known that multiple interactions can occur between nitrogen and water use, depending on climate, soil crop characteristics, in growth yield development. However, little about the simultaneous change both N use efficiency (WUE NUE) their possible cereal–-legume intercropping systems. In order to advance our knowledge facilitation mechanisms involved responses of input co-limitations, ...

This paper reports the results of the first study of an aquaponic system for Pangasianodon hypophthalmus production that uses Lactuca sativa L. (lettuce) and Cichorium intybus L. rubifolium group (red chicory) intercropping in the hydroponic section. The experiment was conducted in a greenhouse at the Zurich University of Applied Sciences, Wädenswil, Switzerland, using nine small-scale aquaponi...

Cotton (Gossypium hirsutum L.) is an important fiber crop in Pakistan with significant economic importance. Transgenic, insect-resistant cotton (carrying a gene from Bacillus thuringiensis (Bt)) was inducted the cotton-based cropping systems of during 2002, and now sown >90% fields country. However, concerns are rising that Bt would decrease productivity winter crops (sown after cotton), lea...

Cropping systems based on carefully designed species mixtures reveal many potential advantages in terms of enhancing crop productivity, reducing pest and diseases, and enhancing ecological services. Associating cereals and legume production either through intercropping or rotations might be a relevant strategy of producing both type of culture, while benefiting from combined nitrogen fixed by t...
