Приведены данные двухлетнего исследования по поиску эффективных препаратов для обеззараживания семян капусты от сосудистого бактериоза. Наилучший результат был получен при предпосевной обработке 0,15%-ной надуксусной кислотой. При этом биологическая эффективность составляла 94,1–97,6%, что значительно превышало соответствующий показатель в эталонном варианте – Фитолавин, ВРК, 0,2% (69,0–72,0%). Показано, что заблаговременная обработка семян НУК (за 550 суток до посева) не оказывала достоверного влияния на их лабораторную всхожесть.Presented data are the result of a two-year study aimed at identifying effective preparations for the disinfection of cabbage seeds from black rot. The best result was obtained by presowing treatment with 0.15% peracetic acid. In this case, the biological efficiency was 94.1–97.6%, which significantly exceeded the corresponding indicator in the reference variant – Phytolavin, VRK, 0.2% (69.0–72.0%). The study has not revealed any significant effect of advance treatment of seeds with peracetic acid (550 days before sowing) on their laboratory germination.

The data for 2018-2019 on tests of the Kamelot herbicide for the protection of soybeans in the Amur Region are presented. The herbicide was applied before soybean germination at a rate of 4 l / ha. The biological efficiency of Camelot was 87-93%, which corresponded to the value of the standard (Frontier Optima). High efficiency of the herbicide was found out against common commeline, white mari, backyard buckwheat and chicken millet. The yield increase was equal to 6.1 c/ha.

The article is focused on the data of the carried works on studying biological efficiency of fungi Triazole 50% on sowing the winter wheat against yellow rust as well as on the height, development and fertility of the wheat. On May 5, 2019 from 9 to 10 o’clock under the temperature 21-23 field experiments of Triazol 50% CS manufactured by the firm “Agroximstar” (Uzbekistan) were carried out on winter wheat as a protector of seeds of winter wheat of Pervitsa sort against the disease of yellow rustin the irrigated conditions in an experimental field of the Institute “Istiklal” of Andijan district of Andijan region. The aim of the given research is to study biological-farming efficiency and determination of optimal norms of preparation expenses and to study the influence of fungicide on the height and development as well as on the fertility of the wheat. The received data showed that the preparation Triazole 50% CS effected on the pathogen of yellow rust favorably and besides that it didn’t effect on seed growth and energy of growth negatively.

Calocybe Indica

The Milky mushroom, Calocybe Indica was cultivated on different agricultural substrate, paddy straw, wheat straw, sugarcane trace and mango dry leaves. The spawning was done by sterilization of all the four substrate. The bags were kept in mushroom growing room with the maintenance of temperature and humidity 30̊ c-35̊ c and 70-80 % respectively. The minimum days requires for completion of spawn run (18.4 days), primordial formation (25.2 days) and days for first harvest (32.4 days) was first observed on cultivation with Paddy straw.  The maximum yield on fresh weight basis and biological efficiency (134.86 %) was also found to be as the same treatment with the Paddy straw as a substrate. The biological efficiency of wheat straw was at par with Sugarcane trace as substrate which was 85.07 % and 85.02 % respectively.

The crop yield and quality of seven annual forages (four grasses and three legumes) in sole crop and in mixtures (ratio 50:50) for oat (Avena sativa L.), Italian ryegrass (Lolium multiflorum Lam.), triticale (x Triticosecale Wittmack), barley (Hordeum vulgare L.), pea (Pisum sativum L.), berseem (Trifolium alexandrinum L.) and common vetch (Vicia sativa L.) were evaluated in a two-year field experiment adopting two harvesting times, green fodder and silage. The main bio-agronomic traits, dry matter forage yield (DMY) and quantity of crude protein (CP) were determined in both sole crop and intercrop. The land equivalent ratio (LER) was used for evaluating biological efficiency and competitive ability of the intercrops. Our results showed that the total calculated LER for fodder and protein yields was always greater than one and corresponded to crop yield advantages of 16.0% and 11.5%, respectively. Our data also highlighted the low competitive ability of the ryegrass in intercrop, which achieved the lowest yield among all the mixtures. Conversely, the same grass showed the best green fodder quality, due to the high incidence of the legume, equal (on average) to 46%. Triticale and barley, harvested for silage (hard dough stage), provided the best quantitative and qualitative results both in sole crop and intercropped with common vetch and pea, determined mainly by the cereal grain.

SUMMARYIt is proposed that two distinct objectives should be recognized in the evaluation of intercropping advantages: (i) a biological objective to determine the increased biological efficiency of intercropping and (ii) a practical objective to determine the advantages that are likely to be obtained by a farmer. The sole crop systems with which intercropping must be compared to satisfy these objectives are defined. Evaluation in relative, absolute, monetary and nutritional units is discussed and some aspects of presenting intercropping data in graphical form are illustrated.
