in order to study the intercropping effects of maize (zea mays l.) and bean (phaseolus vulgaris l.) and evaluating effect of intercropping on weed biomass, a field experiment was conducted at the agricultural research station, payamenoor university of nagadeh,west- azarbayjan, iran during growing season of 2009-2010. the experiment was laid out as randomized complete block design with three rep...
Wheat–chickpea intercrops are not well studied, despite the importance of these two species in increasing agricultural profitability and ensuring nutritional food security. The present study aims to assess intercropping arable system’s services under contrasting field management climate conditions. Simultaneously, this assessment focuses on most agronomic ecological indices widely used literatu...
The Indian population is growing rapidly (1.25 billion) and it has to fulfill its food and nutrition requirement. A collaborative strategy should be adopted for increasing productivity by intensifying available land use system. Intercropping is advanced management practices of soil fertility status, consisting of cultivating two or more crops in the same space at the same time, which have been ...
The changing climate, inadequate water supply, insufficient agricultural inputs, decreasing in arable land areas under forage crops of Northwestern Loess Plateau region, expanding livestock population, increasing demands for meat and milk production, food feed security concerns all insist on a necessary requirement quality production. Cereal–legume mixed-cropping is biological approach to enhan...
Maize ( Zea mays L.) and dry beans Phaseolus vulgaris are important staple food cash crops worldwide. Common bean in an intercrop with maize contributes to biological nitrogen fixation, which stabilize productivity of cropping systems reduce negative environmental impacts loss biodiversity for sustainable agriculture. A field experiments was performed during the years 2020 2021 at Sers El-Layia...
increasing diversity and apply intercropping systems is one of approaches to control of weeds. to evaluate the effects of additive maize-bean intercropping on yield, yield components and weeds in zanjan conditions, a field study was conducted in a spilt plot with randomized complete block design in three replications at research farm of zanjan university in 2010. main plots were the different p...
Wheat/maize intercropping has been widely practiced in northwestern China. It is crucial to optimize the canopy structure and geometric configurations enhance performance of system. This research determined responses intercrops different structures created by wheat/maize systems. Field experiments were carried out 2012, 2013, 2014 at Wuwei, Gansu. Three patterns—six rows wheat alternated with t...
One filed experiment was carried out to study the effect of Arbuscular Mycorrhiza fungi and three preceding winter crops, i.e., Meskawy cultivar Egyptian clover berseem (Trifolium alexandrinum L.), Careem sugar beet (Beta vulgaris) Sakha 94 wheat (Triticum aestivum) five fertilizer combinations as treatments NPK mineral bio which included 100% (T1), 75% + arbuscular mycorrhiza (AMFs) (T2), 50% ...
intercropping is considered for increasing and stability of yield in per unit. in order to study the effects of soybean (glycine max l.) and millet (panicum miliaceum l.) replacement intercropping on agronomic traits, diversity of weeds and soil biological activity, an experiment was conducted at the research station of agricultural faculty, of bu-ali sina university, in 2014. the experiment wa...
in order to study yield and yield components in intercropping bean (phaseolus vulgaris l.) and sweet basil (ocimum basilicum l.) and evaluating effect of intercropping on weed control, a field experiment was conducted at the agricultural research station, ferdowsi university of mashhad during growing season of 2008. treatments: included 1- sole crop of bean 2- sole crop of sweet basil 3- strip ...
