Abstract:

There is lack of information on the yield and yield component performance of same-row and alternate-row mixtures (SRM and ARM) of widely contrasting barley (Hordeum vulgare L.) phenotypes. Therefore, four phenotypically contrasting spring barley cultivars, each selected to represent a unique combination of spike type (two-row or six-row), height (short or tall) and days to maturity (early or late) were used in 1991 and 1992 in field experiments at the Elora Research Station in Ontario, Canada, with the objective of determining whether a yield and/or yield-component advantage could be associate

Abstract:

Twelve early to midseason ripening tomato cultivars were evaluated for early and total marketable yield, fruit size, and external characteristics under the cool, short growing season of northern New England. The acceptability of external and internal color, texture, and flavor of four cultivars was evaluated by a sensory panel of 50 members. There was little difference between cultivars in total yield. This was probably due to an early frost that destroyed much of the later ripening fruit. `Summerset' had the highest early and overall yields but the smallest fruit size. `Johnny's 361` had high

Abstract:

Three studies evaluating production of strawberry (Fragaria × ananassa Duch.) plug plants were conducted. The influence of runner tip plantlet size, container size, and chilling on the field performance of `Chandler' plug plants were evaluated over a 2-year period in central and southern Alabama. Plantlet size did not significantly influence yield following transplanting; therefore, grading of plantlets prior to propagation appears to be an unnecessary expense for successful yields from plug plants. There were no significant differences in yields of plug plants from 60-cell vs. 72-cell packs;

Seed priming enhanced early seeded stands 78% at one site and 76% at a second site in comparison with untreated seed. This priming effect on seedling establishment for the earliest planting led to a 67% increase in early yield (96 days from seeding) and a 28% yield increase over untreated seed at a later harvest. S

The crosses differed significantly in yield in both the F2 and the F3 tests, but the correlation between the tests was not significant (r = 0.189).

Abstract:

Extreme weather events cause considerable damage to the livelihoods of smallholder farmers globally. Whilst index insurance can help farmers cope with the financial consequences of extreme weather, a major challenge for index insurance is basis risk, where insurance payouts correlate poorly with actual crop losses. We analyse to what extent the use of crop simulation models and crop phenology monitoring can reduce basis risk in index insurance. Using a biophysical process-based crop model (Agricultural Production System sIMulator (APSIM)) applied for rice producers in Odisha, India, we simulat

Plants were grown in two field trials, at the Elora Research Station, Ontario, and at the Wye Research and Education Centre, Queenstown, Maryland, and in one greenhouse trial in Guelph, Ontario. Total plant dry weight (PDW) was highly variable for the species, but the higher vegetative vigour of the SOs compared with mid-parent values suggested a

Abstract:

SUMMARYGrain yields of cowpea [Vigna unguiculata (L.) Walp.] in the Nigerian savannas are low even with the cultivation of improved varieties. The recommended spacing for cowpea is 75 × 20 cm with two seeds planted per stand. This corresponds to plant population of 133333 plants ha−1, which may not be sufficient for optimal cowpea yield. Field experiments were conducted to determine plant density effects on cowpea performance in the Northern Guinea and the Sudan savannas of Nigeria and also to determine if genotypes varied in their response to plant density. Four cowpea varieties with contrast

Abstract:

Drought and high temperature are two major factors limiting maize productivity in sub-Saharan Africa. An increase in temperature above 30 °C reduces yield by 1% under optimal rain-fed condition and by 1.7% under drought stress (DS) and up to 40% under combined drought and heat stress (DSHTS). Approaches that improve performance under the two stresses are essential to sustain productivity. The objectives of this study were to (i) assess the extent of variation in tolerance to DSHTS from among the existing best drought tolerant (DT) hybrids; (ii) examine the response patterns of the hybrids to D

Abstract:

Guayule (Parthenium argentatum Gray) is a promising alternative to rubber tree (Hevea brasiliensis Muell. Arg.) for production of natural rubber in semiarid regions. For guayule to be commercially viable, substantial improvement in rubber yield is needed. Field studies were conducted on a dryland site in south Texas to evaluate productivity of selected guayule genotypes from Arizona and California. After 34 months of growth, no significant differences (p= 0.05) were found among the genotypes for rubber yield. However, rubber yields for most of the genotypes increased more than 3-fold from that

Crude protein content of peeled tubers varied between 5.1 and 9.8% of dry matter, yielding 71–540 kg ha−1 of crude protein. Varietal variation in leaf defoliation by the rose beetle, Adoretus versutus Har., was noted.

Abstract:

Various studies model the dynamics of the yield curve assuming that some of the yields are measured without error but this methodology lacks economic interpretation. We overcome this problem by estimating a modified affine model with macroeconomic and latent factors which introduces measurement noise on both yields and macroeconomic determinants. Our results suggest that under the proposed model there is a significant reduction in the persistence of the latent factors and an increase in the effect of macroeconomic shocks to the entire yield curve. We provide a comparative analysis of these mod

Living mulch systems allow cover crops to be grown during periods of cash crop production, thereby extending the duration of cover crop growth and associated beneficial agroecosystem services. However, living mulches may also result in agroecosystem disservices such as reduced cash crop yields if the living mulch competes with the crop for limiting resources. We examined whether the effects of an Italian ryegrass [Lolium multiflorum (Lam.) Husnot]–white clover (Trifolium repens L., cv.
