The effects of Anguina tritici on wheat yields and agronomic components were investigated at Thrace Agricultural Research Institute, Turkey, during the 2013 and 2014 growing seasons. Evaluations during 2013 focused on the wheat cv. Pehlivan, which is widely cultivated in Turkey. In this cultivar, A. tritici led to a grain infection in infected spikes of 0-100%, with an average of 61.8%. In 2014, yield losses caused by A. tritici were investigated in four wheat cvs, Pehlivan, Selimiye, Gelibolu and Kate-A. Results indicated that there were significant yield losses averaging 55% in plots infested with A. tritici (average yields = 3.74 t ha−1), as compared to control plots (average yields = 8.38 t ha−1). Yield losses in the four wheat cvs Kate-A, Pehlivan, Selimiye and Gelibolu were estimated as 51.3, 53.2, 56.6 and 59.6%, respectively, with seed infection levels by A. tritici of 21.4, 20.9, 24.4 and 18.3%, respectively.

Background. For the Trans-Urals, characterized by unstable climate over the years (alternating droughty and excessively moist years, recurrences of colds in spring, possibility of early frosts, etc.), grain quality is a prioritized genetic trait in spring bread wheat cultivars. In Kurgan Province, the share of thirdclass wheat varied since 1994 from 43% to 96%; only in the recent unfavorable years (2015 – 2017) it dropped to 11 – 27% due to rust epidemics. The aim of the study was to characterize the genetic potential of grain quality and its phenotypic implementation in promising cultivars bred at Kurgan Agricultural Research Institute and officially released for cultivation in the region.Materials and methods. The capacities of the KASIB4 – 13 (Kazakhstan–Siberia Wheat Improvement Network under the auspices of CIMMYT) represented by 17 breeding centers in Kazakhstan and Siberia were used to assess grain quality of 14 cultivars with different maturation time bred at Kurgan Agricultural Research Institute. Quality assessment was performed with due regard to the standards of Kazakhstan, CIS, and leading exporting countries, thus combining local and international levels, and employing genetic, biochemical and technological grain quality levels under different soil and climate conditions.Results and discussion. Generally, all cultivars demonstrated protein and gluten content and the level of vitreousness sufficient for strong and valuable wheat. The selected percentage was 92% for hard grain and medium hard grain wheat forms, up to 94% for high-protein and high-gluten ones, and up to 57% for genotypes without 1B/1R wheat/rye translocation. In terms of sedimentation, 86% of the genotypes were predicted to belong to the strong and valuable wheat class; according to the composition of HMW glutenin subunits, mixing quality and flour strength (W), 30 – 42% were identified as high-quality genotypes. The in-depth study of grain quality within the KASIB environmental network revealed heterogeneity among cultivars in a number of genetic and biochemical parameters and provided an opportunity to select high-quality genotypes by marker characteristics and technological properties, which is likely to improve the efficiency of intra-cultivar selection and overall quality assessment of cultivars.

Исследования Уральского НИИСХ и опыт передовых хозяйств Свердловской области показывают, что для повышения эффективности и стабильности кормопроизводства необходимо в структуре кормовых культур увеличивать удельный вес высокобелковых, высокоэнергетических и засухоустойчивых культур, производить подсев многолетних трав ежегодно на площади не менее 60 тыс. га, а в перспективе 7080 тыс. га. За последние 7 лет (20112018 годы) площади люцерны в области увеличились в 2 раза (до 23 тыс. га), кукурузы по зерновой технологии в 2,4 раза (до 20,9 тыс. га) и масличных культур в 3,1 раза (до 30,8 тыс. га). Опыт СПК Килачёвский Ирбитского района показывает, что освоение научно обоснованных биологизированных севооборотов, прошедших изучение в стационарных опытах Уральского НИИСХ, позволяет ежегодно получать высокие и стабильные урожаи всех сельскохозяйственных культур. В этом хозяйстве каждая кормовая культура размещается в своём севообороте. В СПК Килачёвский и ряде других хозяйств Свердловской области большое значение придаётся возделыванию люцерны, кукурузы и масличных культур. Площадь этих культур в расчёте на одну корову мы назвали белковоэнергетическим коэффициентом (БЭК). Анализ показал тесную взаимосвязь между белковоэнергетическим коэффициентом и молочной продуктивностью. Так, в СПК Килачёвский в 2016 году при удое 10196кг БЭК был равен 1,25 в 2017 году удой достиг 10798кг, БЭК 1,43 в 2018 году соответственно 11493 кг и 1,47 при количестве коров 29002977 голов. According to the investigations conducted at the Ural Agricultural Research Institute and experience of the leading farms in the Sverdlovsk region high effectiveness and stability of Forage Production requires wide cultivation of droughtresistant crops rich in protein and energy as well as seeding over 60 thousand ha (in the future 7080 thousand ha) by perennial grasses annually. For the last 7 years (20112018) areas of alfalfa increased by 2 times (up to 23 thousand ha), grain maize by 2.4 times (up to 20.9 thousand ha), oil crops by 3.1 times (up to 30.8 thousand ha). SPK Kilachevskiy (agricultural production cooperative) reported that the use of approved crop rotations tested at the Ural Agricultural Research Institute resulted in annual high and stable yields of all the crops. SPK Kilachevskiy and other farms of the region widely grow alfalfa, maize and oil crops. Land area for the cultivation of these crops per one cow is called proteinenergy coefficient (PEC). Proteinenergy coefficient was shown to have a significant correlation with milk productivity. SPK Kilachevskiy reported that in 2016 PEC and milk yield reached 1.25 and 10196 kg in 2017 1.43 and 10798 kg in 2018 1.47 and 11493 kg, respectively under 29002977 cows.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh for 2 consecutive years during 2007 and 2008 to find out the optimum nutrient management practice for seed yield, nutrient balance and economics of mungbean. Twelve nutrient management treatments were tested in RCBD with 3 replications. Treatments were without CRI T1=HYG (0-24-40-48-24-3-1.2), T2=MYG (0-20-36-40-20-2-1), T3=IPNS (5000-9-37-36-21-3-1.2), T4=STB (0- 20-36-40-22-2-1), T5=FP (0-6-5-4-0-0-0), T6=CON (0-0-0-0-0-0-0) and with CRI T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for mungbean. The maximum seed yield of mungbean was obtained from STB+CRI (1.57 t ha-1) followed by IPNS+CRI (1.54 t ha-1), STB (1.54 t ha-1), IPNS (1.52 t ha-1), HYG+CRI (1.44 t ha-1) and HYG (1.41 t ha-1) in 2007. Similar trend was found in 2008. Numerically higher yield and yield contributing parameters were noticed in CRI plots than without CRI. N and K balance were found negative in all the treatments. P, S, Zn and B balance were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. While in case of FP and CON, the balance was shown almost negative. The maximum gross return and margin was obtained from STB+CRI followed by STB. Slightly higher BCR (3.00) was recorded from STB followed by STB+CRI (2.91).Bangladesh J. Agril.
