Inadequate, unscientific, and lack of optimum utilization fertilizer management devoid site-specific nutrient have been the major constraints maize ( Zea mays L.) production in Nepal. Therefore, a multi-locational farmers’ field experiment entitled “assessing productivity profitability hybrid using Nutrient Expert ® - Hybrid Maize model farmer’s practices was planned executed at two VDCs Morang...

farmers’ fields, it is not clear that breeders have been successful in achieving greater yield potential as defined This paper addresses the question of whether there has been an by Evans (1993), which is the yield of a cultivar when increase in yield potential of maize (Zea mays L.) hybrids released in the north-central United States since the advent of the “Green grown in environments to whic...

fresh water scarcity has become a global problem which needs a serious attempt to find proper solutions for decreasing the pressure on the limited water resources. the exact estimation of crop virtual water would help with choosing crops with high crop and water productivity which lead to both food and water security. thus, in this research, maize virtual water was estimated using hydrus2d base...

Misión Biológica de Galicia, Spanish Council for Scientific Research, Apartado 28, 36080 Pontevedra, Spain Butrón et al. 355 Abstract—The pink stem borer (PSB) (Sesamia nonagrioides Lefèbvre, 1827; Lepidoptera: Noctuidae) is the main insect pest of maize (Zea mays L., Poaceae) in the Mediterranean area. Maize varieties partially resistant to PSB have been identified, but few studies have docume...

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...

ABSTRACT Fusarium spp. in maize can contaminate the grain with mycotoxins if environmental conditions are favorable for fungal growth. To quantify the relationship between growth of Fusarium spp. and environmental conditions, a mathematical model was developed to simulate growth of F. graminearum and F. verticillioides on maize ears following silk inoculation in field experiments from 1992 to 1...

Insect resistance is the second most common trait globally in cultivated genetically modified (GM) plants. Resistance is usually obtained by introducing into the plant's genome genes from the bacterium Bacillus thuringiensis (Bt) coding for insecticidal proteins (Cry proteins or toxins) that target insect pests. The aim of this study was to examine the hypothesis that a chronic, high-dose dieta...

ABSTRACT The salinity of irrigation water or soil is the abiotic factor that most negatively impacts yield crops, including green maize, so it necessary to find alternatives ensure production. In this context, study aimed evaluate gas exchange, photosynthetic pigments, and growth maize under application hydrogen peroxide. experiment was conducted at Center Sciences Agrifood Technology, Pombal, ...

nowadays soil contamination with heavy metals is considered as one of the most serious environmental concerns. among the heavy metals, lead due to inverse impacts on human health and substantial environmental problems causes major concern.this study was carried out with the aim of assessing the ability of different corn cultivars in a greenhouse condition for the accumulation of lead metal. tre...
