Groundnut (Arachis hypogea L.) is a major oilseed crop and holds an important place in the Indian agricultural economy. Odisha occupies 6th groundnut-producing states of country with total production 0.388 MT grown both Kharif Rabi seasons. Harvesting one unit operations groundnut cultivation mechanically harvested by tractor-operated diggers but their use limited because small land holdings hi...

Identifying the underlying mechanisms and the sources of variation in plant productivity is critical to the development of accurate predictive models of ecosystem responses to environmental change, including increased nitrogen (N) deposition and altered precipitation patterns. A great deal of variation in aboveground net primary production (ANPP) in tallgrass prairie may be accounted for by var...

oroginal article tiller is a handy multi – a purpose tractor is used in agriculture. the noise emitted from tiller may be seriously affected auditory system users. the purpose of this study was to evaluate the exposure to noise in operators of this device. in this study 36cultivator tiller was examined. measurement of sound is based in iso 5131-1996 and iso 7216 standard and was conducted in in...

From 1998 to 2001, the relationship between the proportion of tillers with >0 mummified aphids (Ptm) and the proportion of cereal aphids parasitized (Pp) was estimated on 57 occasions in fields of hard red winter wheat located in central and western Oklahoma. Both original (57 fields) and validation data (34 fields; 2001-2002) revealed weak relationships between Ptm and Pp, however, when Ptm > ...

A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...

Drought represents a key limiting factor of global crop distribution. Receptor-like kinases play major roles in plant development and defence responses against stresses such as drought. In this study, LRK2, which encodes a leucine-rich receptor-like kinase, was cloned and characterized and found to be localized on the plasma membrane in rice. Promoter-GUS analysis revealed strong expression in ...

in order to determine the best planting date and seeding rate of two triticale genotype in mashhad climate condition on 2007-2009 growing season, an experiment was carried out, using a split-plot design based on randomized complete block design with three replication, at torogh agricultural research station, mashhad, iran. main plots devoted to five seeding dates and factorial combination of th...
