The experiment was carried out at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Jessore to evaluate the performance of different varieties of hybrid maize under intercropping systems with groundnut in rabi seasons to find out the suitable intercropping system in increasing crop productivity and profitability of consecutive two years (2004 and 2005). ...

Traditional farming practices suggest that cultivation of a mixture of crop species in the same field through temporal and spatial management may be advantageous in boosting yields and preventing disease, but evidence from large-scale field testing is limited. Increasing crop diversity through intercropping addresses the problem of increasing land utilization and crop productivity. In collabora...

M A N Y hybrids between genetic pure lines in maize exhibit heterosis. The search for the genetic basis of heterosis has been carried on for many years and by many workers. Despite these efforts, an adequate, specific biochemical explanation of heterosis has not been presented. JONES (1952) has noted the interaction of nuclear genes and cytoplasm, as evidenced by differences in reciprocal cross...

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...

Background Intercropping is assumed to increase food production while reducing fertilizer needs and environmental impacts of crop production. Aims We aimed (1) investigate the effects intercropping on yields nutrient uptake maize, (2) determine relative contributions above- belowground interspecific interactions (RCabove/below) these effects. Methods conducted a 2-year, small-scale field experi...

the objective of the present field experiment was to examine how plant density and enhanced source, i.e. thinning treatments, may affect grain yield and its components for a non-prolific maize hybrid, sc704. the environment of the hybrid maize crop was changed at intervals over its life cycle by removing every other plant in rows equispaced at 75 cm apart with a population of 13.34 plants m...

In the hopes of lessening the current reliance on soil insecticides, developing a viable alternative for transgenic maize hybrids, and providing sustainable options for Europe, researchers recently have been developing novel maize lines that exhibit resistance and/or tolerance to corn rootworm larvae. Here we report the results of a 2-year field experiment in a northern growing region assessing...

A comparison of oomycete diversity in reed stands ( Phragmites australis ) of Lake Constance, Germany, and maize fields close by provided evidence for the occurrence of natural hybridization between Pythium phragmitis , a newly described reed pathogen, and an as-yet unknown Pythium species closely related to P. phragmitis and P. arrhenomanes . Internal transcribed spacer and β -tubulin sequence...

Faba bean plants (Vicia faba) showed remarkable resistant to wilt disease caused by Fusarium solani pv. Phaseoli when watered with a mixture of heavy metal at a concentration 10mg/L. However the use of Zn, Pb alone slightly increases the susceptibility of bean plants to Fusarium wilt. Plants exposed to Cd or Cu treatment accelerate the symptoms appearance in infected plant. The toxicity of a si...
