Positive Effects

Management practices such as the use of fertilizers and fungicides can have positive effects on grain yield and quality of cereals, especially where diseases are a concern. Six cultivars of six-row barley (Hordeum vulgare L.) were tested at two fertility levels (standard and high) with a late-season application of the foliar fungicide Tilt (propiconazole) to determine their agronomic responses to these management practices. In 1988, when yields were limited because of early season drought, only Leduc showed a positive yield response to the Tilt, even though it has the highest level of genetic resistance to scald and net blotch of the cultivars tested. In 1989, when yields were again limited by adverse environmental conditions, no response to Tilt was found. In 1990, when growing conditions during the season were excellent, Empress, Noble and Samson had positive responses to Tilt application. Tilt had no effect on grain protein, maturity, or harvest index; it slightly improved test weights and kernel weights and decreased percent thins; and it had variable effects on height, number of viable tillers m−2, and kernel number spike−1. Yield response to Tilt was not affected by fertility regime. High fertility (112 kg ha−1 N 37 kg ha−1 P) resulted in an overall increase in yield of 0.62 t ha−1 from the standard fertility treatment (84 kg ha−1 N 27 kg ha−1 P); decreased harvest index; delayed maturity in 1989 only; increased height, number of viable tillers m−2, and kernel number spike−1; increased protein content of the grain in 1988 only; and had no effect on test weight, kernel weight and percent thins. Because of the variability of response from year to year and cultivar to cultivar, the economic feasibility of Tilt application may be limited.Key words: Hordeum vulgare L., propiconazole, soil fertility, management

Yield And Yield Components

A field experiment was carried out to study the influence of sowing times on yield and yield components of barley (Hordeum vulgare L.). Seeds of four barley cultivars (BB 1, Karan 19, Karan 163 and Karan 351) were sown with four sowing times (5 November, 17 November, 29 November and 11 December). Most of the yield and yield components were significantly highest in 17 November sowing. Among the cultivars most of the characters showed their highest values in BB 1 and the lowest in Karan 19. Harvest index was found highest in Karan 351 and lowest in BB 1. Key words: Barley, Sowing time, Yield.   doi: 10.3329/jbs.v15i0.2154   J. bio-sci. 15: 139-145, 2007

Parental Mating

Correlation between grain yield and contributing characters in 100 biparental progenies (BIPs) developed from a barley cross RD-2035 x RD-2552 and corresponding F3 progenies were compared. The correlation coefficients in BIPs were found generally of higher magnitude than F3 progenies. Even, non-significant negative association in F3 between grain yield per plant and harvest index converted into significant and positive in BIP progenies. Higher degree of positive and significant correlation was observed in tillers per plant, spikelets per spike and grain per spike with grain yield per plant in BIPs as well as F3 population.

In general, economic and agricultural policy of the successive Iraqi governments was not toward agricultural development and achieve food security, whether for humans or animals, for dependence on exports of oil to import country's food needs in a difficult currency, which cost the state budget amounts. Scientific and technological underdevelopment, lack of feasibility studies, economic performance,customs, social traditions, religious beliefs and neglect of the farmer caused a lack of interest in the cultivation of barley and its selection of high quality and quantity varieties of grains,straw,land, storage, and marketing operations.The study was conducted to assess the economic feasibility of the productivity of the five Asian barley varieties (Hordeum vulgare L.), (Arivat, Norma ,Iba99 ,NS313 andBip999) for grain and straw yield in Bakrajo area during the winter season of (2015 -2016). The results showed that grain and straw yield parameters were significantly varied according to varieties. Significant increase in grain yield (2720kg/ha), hay yield (3643kg/ha), grain and hay cost (736.180)1000ID/ha, hay revenue (582.880) 1000ID/ha, grain revenue (1019.997)1000ID/ha, profit (866.697)1000ID/ha, seed product (27.200) kg and 1000ID income (2.221) were recorded for NS313 and Bip999 varieties, while the number of grains / spike (44.133) and plant length (89.433) cm was recorded for Iba99 variety.

Aim of study: The study of epigeic arthropods provides information on how ecosystems respond to different management practices. Changes in the structure of epigeic groups reflect changes in the ecological status of habitats. We assessed the influence of semi-natural habitats and environmental variables on the dispersion of the epigeic groups. Area of study: Southwestern part of Slovakia Material and methods: Between 2018 and 2020, six barley (Hordeum vulgare L.) fields were selected each year. Five pitfall traps were placed on each field and environmental variables (soil pH and moisture, light conditions, soil N, P, K) were analysed. We collected 8,730 individuals belonging to 14 taxonomic groups. The variables of the study sites (habitat, locality name, cadastral area, altitude, coordinates of localities) were also analysed. Main results: We observed a decrease in the average number of individuals in the direction from pitfall traps 1 (semi-natural areas) to 5 (barley crop) between July and August. The number of individuals was similar in May and June. The dispersion of epigeic arthropods was affected by soil moisture, pH soil, phosphorus, potassium and nitrogen. In the beetles model group, which was represented by the highest number of individuals, we confirmed an increasing number of individuals with increasing values of K, P, N and soil moisture. The neutral pH of the soil was optimal for beetles. Research highlights: The ecotone rule does not apply during all months, so we have contributed new information about the ecotone rule. Agricultural intensification affects soil arthropods, a taxonomic group with an important role in the functioning of agricultural ecosystems.

Yield Responses

Little information is available on the response of two-rowed barley (Hordeum vulgare L.) cultivars to seeding rate in central Alberta. The objective of this research was to compare the effects of seeding rates of 129–344 seeds m−2 (50–140 kg ha−1) on the agronomic response of two- and six-rowed barley grown in central Alberta. Grain yields of 5.8–6.1 t ha−1 were not affected by seeding rates in 1990 and 1991 at Lacombe. As seeding rates increased in 1992, grain yields at Lacombe increased from 6.4 to 7.8 t ha−1; at Olds, from 3.5 to 4.0 t ha−1; and at Botha for the 129 seeds m−2 treatment, yields were only 5.5 t ha−1, compared with 5.8 to 6.0 t ha−1 for the other treatments. Effects of seeding rate on test and kernel weights varied between location–years. Tiller numbers m−2 were found to increase at higher seeding rates for the two-rowed cultivars, Abee and Harrington, while for the six-rowed cultivars, Noble and Virden, these numbers remained constant. Node numbers spike−1 decreased with higher seeding rates for both two- and six-rowed cultivars. There was little effect of seeding rate on kernel number spike−1 for the two-rowed cultivars, while for the six-rowed cultivars this number decreased. Although the two- and six-rowed cultivars differed in their partitioning of yield and the effects of seeding rates on these components, their yield responses to seeding rate did not differ. Recommended seeding rates for barley in central Alberta should be above 129 seeds m−2 (50 kg ha−1). To maintain high kernel and test weights, seeding rates for barley grown in central Alberta for malt quality should range from 172 to 258 seeds m−2. When conditions warrant accelerated development, seeding rates of 300 or more seeds m−2 should be used. Key words:Hordeum vulgare, management, yield components

Crop Sequence

Rotations are constantly being adapted to current economic and management realities. As a result, the crop sequence used tends to depend more on the economic value of particular crop types, principally cereals, oilseeds and pulse crops in the Saskatchewan Parkland, than on the best management practices for optimizing crop productivity. A study was conducted from 1999 to 2001 at Melfort, SK, to assess the effects of growing barley, wheat, canola, flax, and field pea on their own and the other crop stubbles. When a crop was seeded on its own stubble, the poorest grain yield and quality were recorded, a difference that often was related to major pathogens affecting crop productivity. In the first 2 yr of this study, when near normal temperature and precipitation were recorded, little difference was observed in the average crop yield response when any of the crops were seeded on the other broadleaf and cereal stubbles considered in the study. The exception was flax, which performed poorer when seeded on canola than flax stubble, a reflection of the negative impact canola has on arbuscular mycorrhizae populations on subsequent flax in rotation. In 2001, a year with below-normal precipitation and above-average temperature, crops seeded into pea and flax stubble had yields that were 15–40% of the best stubble treatments. Under these drought conditions, field pea was the best crop choice for flax stubble, while wheat was the best choice for pea stubble. The results of this study indicate that for the Saskatchewan Parkland, the lowest risk crop sequence decision is to avoid seeding a crop in its own stubble.

Thirty genotypes of wheat were evaluated for assessing genetic divergence among eleven different characters across one environment for exploitation in a breeding programme for improving yield of barley by using Mahalanobis D2 statistics. The germplasms were grouped into six clusters. Out of six clusters, cluster I had five genotypes, cluster II had two genotypes, cluster III had ten genotypes, cluster IV had two genotypes, cluster V had eight genotypes and cluster VI had three genotypes based on present investigation. The intra cluster distance among various clusters exhibited maximum intra cluster distance for cluster VI and lowest was recorded for cluster II. The maximum inter cluster distance was revealed between cluster I and V followed by cluster I and VI, cluster III and IV, cluster III and VI , cluster II and IV, cluster III and V and cluster II and V. The least inter cluster distance between clusters IV and VI followed by cluster IV and I and cluster I and II cluster. The phenotypic and genotypic path coefficient exhibited high positive direct contribution of harvest index, number of tillers per plant, number grain per spike and biological yield per plant.
