ABSTRACT The objective of this research was to evaluate combinations of cultivars of coriander and arugula in two croppings with cultivars of carrot in a strip-intercropping system. The study was conducted from November 2014 to March 2015. The experimental design was a randomized complete block in a 2 x 2 x 2 + 2 factorial scheme, with four replications. The treatments consisted of the combination of two cultivars of coriander (Verdão and Português) with two cultivars of carrot (Brasília and Esplanada) and two cultivars of arugula (Cultivada and Folha Larga) in a strip-intercropping system plus two additional treatments, where the first represents the cultivars in monocropping and the second the cultivation types (monocropping and intercropping). The characteristics evaluated in the coriander and arugula were green mass yield and shoot dry mass. The following were evaluated in carrot: shoot dry mass, dry mass of roots, total and commercial productivity, and classified productivity of roots. In the intercropping system, the agronomic indices of land equivalent ratio, productive efficiency index, and score of the canonical variable were evaluated. The economic efficiency indicators determined were gross and net income, rate of return, profit margin, monetary advantage, and modified monetary advantage. There was no significant interaction among the cultivars of coriander, carrot, and arugula for coriander and arugula green mass yields, and for total and commercial productivities of carrot roots. The best polyculture was of that involved in the cultivars ―Português,‖ ―Esplanada,‖ and ―Cultivada‖.

ABSTRACT This study aimed to evaluate combinations of cowpea-vegetable cultivars with carrot cultivars in a strip-intercropping system fertilized with roostertree. The work was conducted at the Experimental Farm "Rafael Fernandes" of the Universidade Federal Rural do Semi-Árido (UFERSA) during September 2013 to March 2014. The experimental design was a randomized complete block with four replications and treatments arranged in a factorial 4 x 2 scheme, resulting from the combination of four cowpea -vegetable cultivars (BRS Tumucumaque, BRS Cauamé, BRS Guariba and BRS Itaim) with two carrot cultivars (Brasilia and Alvorada). The characteristics evaluated in cowpea-vegetables were: number of green pods per area, productivity and dry weight of green pods, number of grains per pod, productivity of grains, weight of 100 grains, and dry weight of green grains. In the carrot cultivars, we evaluated total, commercial, and classified productivity of roots. The cultivar combinations were evaluated in terms of land equivalent ratio, productive efficiency index, score of the canonical variable, as well as indicators of gross and net income, rate of return, profit margin, and modified monetary advantage. The intercropping system using the cultivars BRS Guariba (cowpea) and Alvorada (carrot) achieved highest agronomic/biological efficiency. Highest economic efficiency was achieved with the combination BRS Tumucumaque (cowpea) and Brasilia (carrot).

ABSTRACT The objective of this study was to evaluate the agro-economic efficiency of the intercropping of carrot with cowpea-vegetable under different spatial arrangements and population densities in the semi-arid conditions of the Brazilian Northeast. The study was conducted at the "Rafael Fernandes" Experimental Farm of the Universidade Federal Rural do Semi-Árido (UFERSA) during the period July 2013 to February 2014. The experimental design was of randomized complete blocks with four replications and treatments arranged in a 3 × 4 factorial scheme, where the first factor consisted of spatial arrangements (2:2; 3:3 and 4:4) and the second factor by population densities of cowpea-vegetables (100, 80, 60 and 40% of the recommended population in sole crop [RPSC]). All treatments were fertilized with roostertree (Calotropis procera [Ait.] R.Br.), which is a spontaneous species of the Caatinga biome. The indices of agronomic efficiency of the intercropping systems assessed were: land equivalent ratio, productive efficiency index and score of the canonical variable. The following economic indicators were also evaluated: gross income, net income, rate of return and profit margin. The agro-economic efficiency of the intercropping system of carrot with cowpea- vegetable was influenced by the spatial arrangements, with the 2:2 arrangements standing out from the others. The greatest agro-economic efficiency of the intercropping of carrot with cowpea-vegetable was obtained in the population density of 100% of the RPSC when the value of the productive efficiency index was 0.75.

ABSTRACT The objective of this study was to evaluate combinations of coriander and salad rocket cultivars in bicropping systems intercropped with carrot cultivars in strips under the conditions of Mossoró-RN. The work was conducted at the Experimental Farm Rafael Fernandes from July to December 2014. The experimental design was a randomized complete block design with four replications and treatments arranged in a factorial design with additional treatments of type 2 x 2 x 2 + 2. The treatments consisted of the combinations of two coriander cultivars (Verdão and Português) and two rocket cultivars (Cultivada and Folha Larga), intercropped with two carrot cultivars (Brasília and Esplanada) plus two additional treatments, where the first are the cultivars in monocropping and the second the types of cropping (single and intercropped). We evaluated fresh and dry shoot mass in coriander and rocket and fresh and dry shoot mass as well as dry root mass, commercial and total root productivity, and classified root productivity in carrot. In the intercropping systems we evaluated land equivalent ratio, productive efficiency index, and score of the canonical variable, besides the indicators of economic efficiency (gross income, net income, rate of return and profit margin). Highest agroeconomic efficiency in intercropping systems was achieved with the combination of the coriander cultivar 'Verdão' and the rocket cultivars 'Folha Larga' or 'Cultivada' as well as the carrot cultivars 'Brasília' or 'Esplanada'. Regardless of the tested cultivar combinations, systems with coriander and salad rocket intercropped with carrot showed higher efficiency than monocropping systems.

The article presents the results of studies on the adaptive potential of sorghum used for restoration of degraded pasture ecosystems, increasing their biodiversity and nutritional value. The region chosen for the experiment is a semi-desert arid part of southern Russia. The aridity coefficient is 0.11–0.30 which is typical of the arid zone. The annual volume of precipitation is 125-265 mm. Two varieties of sorghum – Travinka and Caravan – were studied. They were grown with different thickness: 10 thousand, 20 thousand and 40 thousand plants per 1 hectare. During the growing season, there was soil and atmospheric drought. The best indicators of green mass yield were recorded for Travinka for the variant “40 thousand plants per hectare – 7.9 tons per hectare, and for Caravan for the variant “20 thousand plants per hecrate – 3.9 tons per hectare. Compared with natural pasture, sorghum productivity is 18 times higher by green mass yield and 26 times higher by dry mass yield (the best options). The analysis of the chemical composition and nutritional value of sorghum showed that compared to the plants of natural pasture, sorghum is a more nutritious fodder plant. Its nutritional value is more by 0.24 feed units per 1 kg and by 1.9 % by the mass of crude protein. It is better than other plants by the content of sugar content (79 g per 1 kg) and macronutrients.

Investigation of quantitative traits of Jerusalem artichoke populations was conducted on the experimental field of the Agricultural Institute of the Republic of Srpska in Banja Luka, during 2013 and 2014. The material was collected in the wider area of Republic of Srpska. The following populations were analyzed: Srbac, Modrica, Pivara, Lazarevo, Bosna, Vrbas, Gradiska and Aleksici. The trial was arranged in a randomized complete block design with three replications. The following parameters were analyzed: tuber weight (g), plant height (cm), stem number/plant, average stem thickness (cm), green mass yield/plant (kg), and dry mass yield/plant (kg). Average tuber weight ranged from 36.7 g (Bosna) to 61.0 g (Lazarevo). Plant height ranged from 1.55 m (Lazarevo) to 2.20 m (Aleksici). Stem number/plant varied from 2.2 (Aleksici) to 5.3 (Modrica). Stem thickness was between 1.24 cm (Bosna) and 2.11 cm (Aleksici). The population Bosna had the lowest average yield of green mass and dry mass yield/plant, while the highest mean value had population Aleksici. Broad sense heritability varied from 34.66% (plant height) to 50.99% (dry mass yield/plant). Highly significant positive correlations between plant height and stem thickness (r = 0.874), stem thickness and green mass yield (r = 0.919), stem thickness and dry mass yield (r = 0.902) were established. Jerusalem artichoke populations were clustered into two groups, and the first group was composed of two sub-groups. The results of these studies will allow choice of Jerusalem artichoke populations with better quantitative traits, and their inclusion in the program of creating new varieties.

Abstract. The purpose of the research is to conduct the comparative assessment of variable alfalfa varieties and to identify the most productive and adapted varieties to the conditions of the region with a view to their further zoning. The results of research on the study of alfalfa varieties – Karabalykskaya 18, Rambler, Ural’skaya sinyaya, Semirechenskaya mestnaya, Krasnovodopadskaya 8 are presented in this article. Data of the seed germination and plant preservation by years of life, yield and forage capacity of crops are given. Methods: field and calculation (to determine the feed capacity). Results. In the 2011 crops, according to the field germination, the variety of Karabalykskaya 18 (45.8 %) and Semirechenskaya mestnaya (42.8 %) were distinguished. According to 4-year data, the highest percentage of preservation in the variety of Karabalykskaya 18 (14.2 %) and Ural’skaya sinyaya (13.9 %). And the smallest number of preserved plants was noted in the alfalfa variety of Krasnovodopadskaya 8, it is amounted to 10.4 %. The crops produced more mass shoots in next year, due to somewhat high rates of spring precipitation and air temperature. And in terms of the percentage of preservation, the 2012 crops surpassed the previous ones. Thus, in the variety of Karabalykskaya 18 and Rambler, this indicator was equal to 15.1 % and 13.7 %, and in the zoned variety Ural’skaya sinyaya, 15.7 % of the herbage was preserved. The data of green mass yield determination and hay shows that three of the four varieties evaluated were exceed to the standard variety from 1.6 to 8.5 per 1 ha for the collection of green mass and from 0.2 to 2.4 c/ha for the hay harvest. In terms of feed capacity, the highest indicators are in the Karabalykskaya variety 18, and the lowest – in Krasnovodopadskaya 8. So, at the 5th year of life (sowing 2011), 48 cattles can be fed on 10 ha of crops of the first variety for a month, and the second – 41. On the grass stands of the zoned Ural’skaya sinyaya variety, the content of 43 cattles are permissible.
