background and objectives: seedy watermelon (citrullus lanatus) is a crop that is planted in as a second crop after winter crops some parts of country. this crop is more attended by farmers due to the short time between planting and maturity, low production costs and greater profitability rather than other spring crops. in order to evaluate the interaction effects between weeds and seed priming...

The application of organic and inorganic fertilizers together increases crop productivity soil fertility. However, it is crucial to identify the combined level. A field experiment was carried out in Guto Gida district 2021 determine effect vermicompost levels chemically mixed NPSZnB fertilizer rates on growth yield maize. Four (0, 2.5, 5, 7.5 t·ha−1) with four artificial 50, 100, 150 kg·ha−1) w...

Genetic dissection of complex traits by quantitative trait locus (QTL) analysis permits the understanding genotypic effects QTL, interactions between QTLs, and QTL-by-environment in wheat. This study aimed to identify QTL linked yield, its components, end-use quality including kernel, flour, dough rheology, related agronomic under dryland irrigated conditions. A mapping population 179 F2:6 reco...

a field experiment was conducted at the seed and plant improvement institute research field station in karaj, iran, during the 2009-10 and 2010-11 growing seasons to estimate genetic progress and the variation in penological and agronomic characteristics in 13 irrigated facultative/winter bread wheat (triticum aestivum l.) cultivars released in iran between 1943 and 2011. trends of temporal var...

In Afghanistan, the greatest challenges in agriculture system are major soil erosion, high moisture loss, and farming of same crop every year leads to drop fertility level soil. Conservation Agriculture defined by three principles namely minimum disturbance, rotation permanent cover. A field experiment was conducted during winter summer season 2018 at research farm Dehdadi, Balkh, Afghanistan. ...

The objective of this study was to investigate the effect ultrasound pre-treatment (50% US and 100% US-soaking), temperature (80, 90 100 ᵒC) dryer type (hot-air convection vacuum) on some physical characteristics such as hectoliter weight, thousand kernel dimensions (thickness, length, width, equivalent diameter sphericity) corn during drying. Before drying, samples were pre-treated without (co...

abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...

this study was carried out to investigate the important characteristics in some cultivars/genotypes of persianwalnut (juglans regia l.), black walnut (j. nigra l.), and walnut inter-specific hybrids: paradox (j. hindsii × j.regia) and royal (j. hindsii × j. nigra) in kamalshahr research station in karaj in 2011-2012. in the study,vegetative vigor was evaluated based on trunk cross-sectional are...

the initial step in any breeding program including the breeding of walnut is an evaluation of the genetic diversity of its population and on identification of its superior and promising genotypes. this research was carried out during 2009-2010 growing seasons to evaluate the walnut genotypes, population grown in the vicinities of eghlid city, as one of the richest walnut population regions in t...
