Winter oilseed rape was cultivated in monoculture or in combination with turnip rape as trap crop sown in trap strip. Preventative microbiological treatments for diseases control in winter oilseed rape were tested using Trichoderma asperellum and product based on effective microorganisms. Microorganisms were effective to protect of oilseed rape and allowed to obtain higher yield comparing to un...
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...
Artificial diversity is one method for mitigating the security risks of software monoculture. Introducing diversity increases resilience by obfuscating the system parameters an attacker must control for a successful exploit. We take a different approach to resilience and introduce the concept of Application Communities (AC): collections of independent instances of the same application that coop...
The rapidly growing car industry in China has led to an equally rapid expansion of monoculture rubber in many regions of South East Asia. Xishuangbanna, the second largest rubber planting area in China, located in the Indo-Burma biodiversity hotspot, supplies about 37% of the domestic natural rubber production. There, high income possibilities from rubber drive a dramatic expansion of monocultu...
it is known that legumes give benefits to the soil such as improved nutrient availability, improved structure, reduced pest and disease incidence, and hormonal effects (wani et al., 1995). the major benefit of legume crops comes from biologically nitrogen fixation, deriving from the symbiosis involving leguminous plants and rhizobium bacteria (vance, 1998). based on this purpose, a field study ...
This study was aimed at evaluating the effect of crop rotation and various tillage systems onthe chemical and biological properties of soil in the years 2013-2015. The first order factorincluded cropping systems: a) crop rotation (pea – winter wheat – spring wheat) and b)monoculture of winter wheat, whereas the second order factor were tillage systems:1) conventional (CT), 2) reduced (RT) and 3...
in order to evaluate the density, population and insect fauna diversity and agronomical yield in intercropping faba bean (vicia faba l.) andcoriander (coriandrum sativum l.), a field experiment was conducted based on a randomized complete block design with three replications at the farm located in nagadeh, west azerbaijan province, iran during growing season in 2012-2013. treatments included 75...
Crop performance in rainfed cropping systems generally is dependent on rainfall amount and distribution. The objective of this study was to analyze the long-term consequences of rainfall expressed as a standardized precipitation index (SPI) and fertilizer nitrogen (N) on yields and risk probabilities of maize in the udic-ustic moisture regimes in the Great Plains in Nebraska. The SPI is a preci...
