Food security and land required for food production largely depend on rate of yield gain of major cereal crops. Previous projections of food security are often more optimistic than what historical yield trends would support. Many econometric projections of future food production assume compound rates of yield gain, which are not consistent with historical yield trends. Here we provide a framewo...

Introduction Yellow mustard (Sinapis alba L.) is a new multipurpose rotation oilseed crop for Willamette Valley agriculturalists, especially non-irrigated operations. Yellow mustard can also be used to produce condiment mustard, as a green manure crop, and as a biopesticide. Although yellow mustard seed production is relatively new to the Willamette Valley, Oregon’s north-central counties have ...

The task of identifying genomic regions conferring yield stability is challenging in any crop and requires large experimental data sets in conjunction with complex analytical approaches. We report findings of a first attempt to identify genomic regions with stable expression and their individual epistatic interactions for grain yield and yield stability in a large elite panel of wheat under mul...

A pot experiment was conducted during 2010-11 in the Department of Agriculture Botany Janta P.G. College Ajeetmal, Auraiya(U.P.), India. Eight genotypes of wheat are selected with varying in their salt tolerance level, to evaluate effect of salinity on germination, growth, and yield related parameters. Lower salinity (3dsm -1 ) did not affect the germination, growth and yield attributing parame...

Brassica napus was synthesized by hybridization between its diploid progenitor species B. rapa and B. oleracea followed by chromosome doubling. Cross with B. rapa as a female parent was only successful. Among three colchicine treatments (0.10, 0.15, and 0.20%), 0.15% gave the highest success (86%) of chromosome doubling in the hybrids (AC; 2n = 19). Synthetic B. napus (AACC, 2n = 38) was identi...

Research Article Stability analysis for grain yield and yield components in chick pea (Cicer arietinum l.) Abstract: Twenty one advanced breeding lines selected from All India Coordinated trials and one local popular variety " annegiri' were studied over three years to identify high yielding stable genotypes. Genotype , environment and G x E interaction variance found to be significant. Genotyp...

In order to elucidate the effect of sowing date on oilseed rape (Brassica napus L.) yield and yield components, three varieties including Tower, Rafal and Global were sown from November 7 to December 22, 1998-99 in four dates with 15day intervals in Dezful region. A split-plot design based on randomized complete blocks with four replications was used in which levels of sowing dates and cultivar...

Despite the routine collection of annual agricultural surveys and significant advances in GIS and remote sensing products, little econometric research has integrated these data sources in estimating developing nations' agricultural yields. In this paper, we explore the determinants of wheat output per hectare in Ethiopia during the 2011-2013 principal Meher crop seasons at the kebele administra...

The objective of this study was to determine the specific methane yields of four grass species (cocksfoot, tall fescue, reed canary grass and timothy) cultivated under boreal conditions as well as how harvesting time and year of cultivation affects the specific methane yields per ha. The specific methane yields of all grasses and all harvests varied from 253 to 394 Nl CH4/kg volatile solids (VS...

This research was conducted to determine responses of chickpeas to drought in different periods (early period, late period, no-irrigation, two times irrigation as control). The trial was made in “Randomized Complete Block Design” with three replications on 2010 and 2011 years in Konya-Turkey. Genotypes were consisted from 7 lines of ICARDA, 2 certified lines and 1 local population. The results ...
