Currently, mixed systems for growing annual crops with forage plants of the Brachiaria genus represent an excellent alternative for the cultivation of maize by using the area for agricultural and livestock farming, which provides higher income to the grower and sustainability to the agricultural systems of the Cerrado. However, little is known about the best means for sowing such intercropped plants. Thus, the objective of this study was to evaluate the agronomic characteristics of maize (Zea mays) as well as the productive and nutritional characteristics of Paiaguas palisadegrass (Brachiaria brizantha cv. BRS Paiaguas) as the second crop in integrated production systems. The experimental design used randomized blocks with four replications. The treatments consisted of the following forage systems: monocropped of maize, monocropped of Paiaguas palisadegrass, maize intercropped with Paiaguas palisadegrass in rows, maize intercropped with Paiaguas palisadegrass between rows, and maize with oversown Paiaguas palisadegrass. The results showed that intercropping of maize with Paiaguas palisadegrass does not interfere with the agronomic characteristics or grain yield of maize, regardless of the system that was adopted. Regarding the production of forage, low production of dry matter was found for Paiaguas palisadegrass oversown in maize, though the nutritional value was better. Intercropping maze and Paiaguas palisadegrass is relevant to integrated production systems, as it allows for of a third harvest in the same crop year, which maintains sustainability especially because a smaller arable area is used compared to conventional systems.

<p>Common buckwheat (<em>Fagopyrum esculentum</em> Moench) has attracted much attention due to its high nutritional value and medicinal properties. The crop has a long history of cultivation in Japan, and today, it is used mostly for manufacturing soba noodles which are quite popular in Japanese cuisine. Cultivation of common buckwheat in the country decreased gradually until the 1970’s, but has started to increase again in recent years. In this paper, we provide an overview of common buckwheat production in Japan with emphasis on the agronomic characteristics of representative Japanese cultivars and landraces.</p>

ABSTRACT: The process of protein enrichment of cactus pear (Nopalea cochenillifera (L.) Salm Dyck by solid state fermentation with the use of Aspergillus niger and Rhyzopus sp. was studied for improving the nutritional value of this cactus species for use as animal feed. The experiments were conducted in the Agro-industrial Waste Laboratory of State University of Southwest Bahia (Brazil). To this end, we have evaluated the effects of biotransformation on the levels of protein, cellulose, hemicellulose, and lignin, as well as the potential degradability. Bioconversion was carried out using cactus pear as the only substrate, without supplementation with nitrogen, mineral and vitamin sources. The fermentation with Aspergillus niger promoted a 78% increase in/of protein content and reductions of cellulose, hemicellulose, and lignin of 40%, 36%, and 28%, respectively. Degradability, in turn, was observed to have increased by 66 % after 240 h. On the other hand, the fermentation with Rhyzopus sp. was less efficient, with a 69% increase in protein content, and reductions in cellulose, hemicellulose, and lignin contents of 30%, 28%, and 18%. In turn, degradability was seen to have increased by 51%. The fermentation of cactus pear by Aspergillus niger and Rhyzopus sp. exhibited the protein enrichment and increased protein degradability of this Cactaceae. Moreover, this is the most ever efficient micro-organism used in bioconversion. Based on the results, bioconversion of cactus is an excellent alternative to ruminant feeding in arid or semi-arid land.

Intercropping of annual crops with tropical forages is an effective cultivation method to maximize grain production and pasture formation. The objective of this study was to evaluate the agronomic characteristics of sunflower and the productive and nutritional characteristics of Brachiaria brizantha cultivars grown with intercropping during two different sowing seasons in the interim harvest of the Center-West region of Brazil. The experiment was conducted in the municipality of Rio Verde, Goiás (GO), using a randomized block design with a 3x2+4 factorial scheme and three replicates per treatment. The following factors were tested: three Brachiaria brizantha cultivars (Marandu palisadegrass, Piata palisadegrass and Xaraes palisadegrass) grown with intercropping in the inter-row with the sunflower cultivar Charrua in two different sowing seasons (February and March); four additional treatments of sunflower; and the three tested Brachiaria brizantha cultivars grown in monoculture. Intercropping of sunflower with the Xaraes palisadegrass cultivar negatively affected the agronomic characteristics of sunflower, and intercropping with Marandu palisadegrass and Piata palisadegrass cultivars is recommended. Preference should be given to the Xaraes palisadegrass cultivar for forage production and to the Piata palisadegrass cultivar for the production of forage with higher nutritional value. Sowing in March led to the best sunflower agronomic characteristics, without affecting the productive and nutritional characteristics of the forages. Intercropping of sunflower with Brachiaria brizantha cultivars is therefore a promising cultivation method for the production of achenes and forage during the inter-harvest in the Center-West region of Brazil.

Sweetpotato has recently received much attention due to its many agricultural advantages such as its adaptability to different environmental conditions and its nutritional value. It has been grown in Japan for more than 400 years, and the bulk of the Japanese harvest is presently destined for fresh market consumption as well as for the food and beverage processing industry. This review begins by providing an overview of the commercial production and agronomic characteristics of sweetpotato cultivars in Japan. The paper deals with the possible ancestry of Japanese sweetpotatoes, and finally describes several orange- or purple-fleshed genotypes that are adapted well to cold northern climates and considered as valuable sources for enhancing the physiological functionality of this crop.

This study aimed to evaluate the agronomic characteristics and nutritional value of two clones of elephant grass (CNPGL 00-1-3 and BRS Kurumi) operating under rotational stocking in the dry season. A completely randomized design with repeated measures (grazing cycles) and three replicates (paddocks) was used. Clones were managed under rotational stocking with a defoliation interval of 24 days and four days of occupation of paddocks, using Holstein x Gyr heifers with mean body weight of 150 kg. The evaluations were conducted in April/May, May/June, June/July and July/August 2010. Green forage mass was influenced by clone and grazing cycle, with higher mean value observed for CNPGL 03-01-00, which was 17% higher than the value observed for BRS Kurumi, and there was decreased of dry mass of green forage with the advance of grazing cycles. Leaf mass was influenced only by grazing cycle, with gradual reduction from the first to the third cycle. However, in fourth cycle was increase in biomass of leaves, which did not differ from that observed in the second cycle. There was interaction for dry matter production of stem, being observed differences in the first and third cycles for the clones. There was no effect of the factors studied for the production of senescent material. The leaf:stem ratio was influenced by grazing cycles, with interaction of the factors studied. The clone BRS Kurumi kept the leaf:stem ratio stable over the cycles, while clone CNPGL 1-3-00 presented a decrease in leaf:stem ratio from first until to third cycle. The content of crude protein (PB) was not influenced by the factors studied, with average values of 15.3% and 15.8% PB for the CNPGL 00-1-3 and BRS Kurumi clones. Neutral detergent fiber (NDF) and the in vitro dry matter digestibility (IVDMD) were affected only by grazing cycles. The highest values of NDF were observed in the three first grazing cycles, with values of 55.5%, 56.0% and 55.7% from the first to the third grazing cycle, respectively, while in the fourth cycle was obtained the value of 50.5%. There was a decrease in the IVDMD until the third cycle. In the fourth cycle the IVDMD values were similar to the first cycle. The clones did not differ in relation to biomass production, morphological composition and nutritional value, during the dry season.

The article raises the problem of ensuring metrological traceability of the measurement results of indicators of quality and nutritional value for food products and food raw materials: water (moisture), nitrogen (protein, crude protein), fat, ash and carbohydrates. The problem under consideration can be solved by applying reference materials of food composition, traceable to state primary measurement standards GET 173-2017 and GET 176-2019 and primary reference measurement procedures (PRMP), for attestation of measurement procedures and accuracy checking of measurement results. The article discusses the results of the PRMP development of mass fraction of fat, ash and carbohydrates in food products and food raw materials, as well as mass fraction of crude fat (oil content) in oil crops seeds and products based on them. The paper also presents metrological characteristics of reference materials of composition of dry dairy products, grain-milk dry porridges for nutrition of babies, grain dry porridges for nutrition of babies, egg powder, freeze-dried meat products, animal feed. The results of the work allow for building a chain of metrological traceability from GET 173-2017, GET 176-2019 and PRMP to routine measurement procedures, thereby ensuring the uniformity of measurements of nutritional value of food products.
