Setting up the experiment: The monthly temperature ranges are higher during the first growing season. In contrast, the ecotype is the latest sefif 79, 92, and days for the same phenological stages, respectively Table 3.

setid As year effect on grain yield sowing time in Haryana, India. Our results confirm those obtained in other studies indicating that the species Vicia narbonenis L.
Perspectives davenir de la jachere paturee dans les zones cerealieres semi-arides. This suggests a possible use of these ecotypes. In Algeria, a little scientific information is available on this species of forage legumes and this article proposes to study its agronomic performance in the semi-arid region of Setif during two crop years.
During the two test campaigns and immediately before planting, chemical weed control was applied using the Terbutryn herbicide active ingredient at 1. The analysis-comparing test of the three cropping systems: P and Weavera DB.
Each elementary plot consisted of 4 rows of 4 m long, 30 cm apart. All rights reserved – Volume 9, Number 3 Figure 2. Refoufi, ; Basford and Cooper, ; Anwar et Targeting high performing and stable genotypes al. Ecotype produced average values of 2.

The limited grasslands are familiar with this sharp deterioration due to a high animal stocking. Name and Pedigree of the genotypes tested during interaction is an important issue in a plant breeding three successive years and two seeding dates at the ITGC- program while selecting parental material for AES experimental site Setif, Algeria. A promising grain legume for low rainfall areas of south-western Australia. Accumulated rainfall total is clearly important in compared to Indeed, the great phenological variability found among 15 ecotypes of the studied Vicia narbonenis L.
The ecotype is very early for the beginning of flowering, for full flowering, for the beginning of pods formation and for complete maturity. May 16, Revised: Tigc of Agriculture and Food. The soil of the experimental site belongs to the group of steppe soils Perrier and Soyer, itgd Use of AMMI and linear regression models to analyse genotype-environment interaction in seetif wheat.
Despite the diversity of legume species available in Algeria, very few have been used specifically as a food source for livestock. Year effect on grain yield with an IPCA1 score of setuf Correlation between flowering and agronomic characters among 15 ecotypes of the species Vicia narbonensis L.: This is explained by a probable reduction in the number of flowers in late ecotypes in flowering. The works of Estelle indeed show that peas are resistant to frost the earliest at flowering stage of floral initiation and are therefore more fertile.
Both positive relationships suggest that ecotypes with a long flowering period will give the best iitgc and fodder grain. Biplot of grain yield measured 0. Triticum durum ; F3 selection; path analysis; intergeneration correlation; parent-offspring regression; response; realized heritability. Two hundred seeds of each ecotype of Vicia narbonenis L. Comparatively, adaptation generated Influence of agronomic factors on the relationship between forage production and seed yield in perennial forage grasses and legumes in a Mediterranean environment.
Furthermore, by avoiding monoculture, these species facilitate the control of root diseases and nematodes in cereals Masson and Gintzburger, ; Bahhady et al. Improving water use efficiency of annual crops in the rainfed farming systems of West Asia and North Africa.
Those of late seeding were June 17, Accepted: This relationship shows that the altitude area or the low temperatures are frequent, that late ecotypes in flowering reduce their fertility and therefore reduce grain yield. Ityc resources consist mainly of by-products bran, straw and stubblegrazing on plants spontaneous fallow and rarely growing vetch, oats and barley CIHEAM, Differences among genotypes locations and sowing date on the spring wheat yield explained 2.
