Multivariate Interaction Analysis of Winter Wheat Grown in Environment of Limited Soil Conditions

Abstract

The less productive soils present one of the major problems in wheat production. Because of unfavorable conditions, halomorphic soils could be intensively utilized using ameliorative measures and by selecting suitable stress tolerant wheat genotypes. This study examined the responses of ten winter wheat cultivars on stressful conditions of halomorphic soil, solonetz type in Banat, Serbia. The wheat genotypes were grown in field trails of control and treatments with two soil amelioration levels using phosphor gypsum, in amounts of 25 and 50 tha−1. Across two vegetation seasons, phenotypic variability and genotype by environment interaction (GEI) for yield traits of wheat were studied. The additive main effects and multiplicative interaction (AMMI) models were used to study the GEI. AMMI analyses revealed significant genotype and environmental effects, as well as GEI effect. Analysis of GEI using the IPCA (Interaction Principal Components) analysis showed a statistical significance of the first two main components, IPCA1 and IPCA2 for yield, which jointly explained 70% of GEI variation. First source of variation IPCA1 explained 41.15% of the GEI for the grain weight per plant and 78.54% for the harvest index. The results revealed that wheat genotypes responded differently to stressful conditions and ameliorative measures.

Buckwheat Yield Traits Response as Influenced by Row Spacing, Nitrogen, Phosphorus, and Potassium Management

“…Plant yield strongly depends on the soil conditions in which the root system develops. The quality of soil conditions is defined by the favorable water-air regime, mechanical composition, and supply of soil nutrients [22][23][24][25][26][27][28][29][30][31]. The soil in the experimental plot had, at depths of 0-30 cm and 30-60 cm, a low alkaline and neutral reaction (pH in H 2 O = 7.01 and 6.50).…”

Spike index stability of bread wheat grown on halomorphic soil

“…The high impact of climatic conditions, in the experimental years on grain yield and its components, was reported by several authors (Tarakanovas and Ruzgas, 2006;Ljubičić et al ., 2010;Ljubičić et al ., 2021) .…”

Analysis of Climate Elements in the Northeastern Region of Croatia for the Purpose of Determining Irrigation Requirements of Maize and Soybean on Drained Soil

“…Climate has a great influence on the growth and development of plants, so the elements of climate (light, heat, air and water) very often appear as a limiting factor (Popovic et al, 2012;2020c;Ljubicic et al, 2021). Significantly higher total precipitation for the vegetation period of winter cereals was in the first year of testing of 652 mm was higher compared to the precipitation for the multi-year average for the area of Pancevo by 130 mm while temperatures were lower by 0.33°C.…”
