Sunflower is the main oilseed crop for our country, occupying about 85% of the area of industrial crops. The oil made from sunflower seeds has high taste quality and it is used in everyday life, food and pharmaceutical industries. The sunflower cake and meal are additional products from the processing that are valuable concentrated feed for all livestock. Broad application, favorable soil and c...

Host suitability of commercial sunflower hybrids to Pratylenchus zeae was studied in the field and greenhouse. For comparison, one maize and one grain sorghum inbred line, both susceptible to P. zeae, were included in the greenhouse experiments. Pratylenchus zeae densities extracted from the roots of sunflower hybrids grown in naturally infested soil were low. In the first greenhouse experiment...

Sunflower (Helianthus annuus L.), with its high oil quality, is one of the major and most valuable oilseed crops in the world. Sunflower rust, caused by Puccinia helianthi Schw., is one of the major foliar diseases of sunflower. The pathogen is present wherever sunflower is grown in the world and causes important yield losses when severe epidemics occur. The objective of this study was to ident...

Nonlethal alternatives are needed to manage blackbird (Icterids) damage to rice and sunflower production in the United States. We evaluated 4 registered fungicides on rice seeds (i.e., AllegianceH FL, Thiram 42-S, TrilexH, and VitavaxH 200 preplant seed treatments) and 2 foliar pesticides on sunflower seeds (Cobalt insecticide and Flock Buster bird repellent) as candidate blackbird repellents. ...

to study the effects of foliar application of common and nano-sized iron sulphate on five sunflower cultivars (alster, olsion, hysun36, yourflour and hysun33) under two levels of salinity (0 and 100 mm nacl), a pot experiment in factorial based using a randomized complete block design with three replications was conducted. plant height, leaf area, shoot weight, chlorophyll content and the conce...

Forty midlactation Holstein cows averaging 635 kg of body weight (SE = 8) were allotted at wk 25 of lactation to ten groups of four cows blocked for similar calving dates to determine the effects of formaldehyde treatment of flaxseed and sunflower seed on fatty acid composition of blood and milk, milk yield, feed intake, and apparent digestibility. Cows were fed a total mixed diet based on gras...

Abstract Background and aims Soil carbon sequestration can play an important role in mitigating climate change. Higher organic C inputs to agricultural soils are needed order increase soil (SOC) stocks. Genotype selection breeding towards increased root biomass may enhance the could therefore be a promising, easy-to-implement management option for potentially increasing sequestration. However, ...

The quality and quantity of the influence that atmospheric CO2 has on crop growth is still a matter of debate. This study’s aim is to estimate if [CO2] will have an effect on biomass yields at all, to quantify and spatially locate the effects and to explore if an elevated photosynthesis rate or water-use-efficiency is predominantly responsible. This study uses a numerical carbon-based crop mode...
