The goal of this work was to evaluate the growth dynamics and chemical characteristics of the upper and lower strata of summer perennial grasses under a four cuts system. The experiment was conducted in a randomized block design, composed of 28 treatments in a factorial arrangement of 7x4, with four repetitions. The cultivars evaluated were Star Grass, Coast-cross, Tifton 68, Tifton 85, Jiggs, Roxinha and Quicuio. Each cultivar was cut when it reached 95% light interception. The cultivars Jiggs and Tifton 68 had the highest (P < 0.05) accumulation of dry biomass ha-1 during the four cuts, with productions of 21,348 and 21,016 kg ha-1, respectively. The ash content varied (P < 0.05) among species and times of cutting for both strata. Cellulose contents were significantly different in the upper stratum, with the highest concentrations found in cvs. Quicuio and Tifton 68 (39.12% and 38.07%, respectively). We found the highest levels of lignin (P < 0.05), for both strata, in cv. Quicuio. Cultivars Jiggs and Tifton 68 were the most appropriate for a management system of four cuts, displaying good chemical composition and high productivity.

Silage Production

This study aimed to evaluate the production, the physical and nutritional composition of forage and silage, as well as the profitability and aerobic stability of different winter cereals harvested at the stage of floury grain. The experimental design was a 2x7 factorial randomized block design, with two forms of foods (fresh forage and silage) and seven genotypes, with four replications. The genotypes used were the white oat (Avena sativa) cv. URS Taura; barley (Hordeum vulgare) cv. BRS Brau and cv. BRS Cauê; wheat (Tricticum aestivum) cv. CD 1440; rye (Secale cereal) cv. BR 01; and triticale (X Triticosecale) cv. IPR 111 and cv. BRS Saturno. The materials were harvested during the stage of floury grain. In forage evaluation, rye showed the highest (P < 0,05) dry biomass production (7,100 kg ha-1), but with a higher percentage of stem (46.7%) in dry matter, implying higher ADF (44.69%) in relation to other cereals. The forage of the white oats cv. URS Taura and triticale cv. IPR 111 provided the best nutritional quality compared to the other evaluated cereals, but in the resulting silage, only triticale remained with forage-like characteristics. It was clear the superiority of barley cv. BRS Cauê, wheat cv. CD 1440 and rye cv. BR 01 regarding the maintenance of aerobic stability (160 hours), while the other silages lost their stability within 32 hours. Rye cv. BR 01 and triticale IPR 111 presented the highest production of recovered dry biomass (5,402 and 5,352 kg ha-1 respectively), barley cv. BRS Cauê and oat URS Taura provided higher cost of production per kg-1 dry biomass, both with R$ 0.29 and higher cost per kg of recovered dry biomass R$ 0.45 and 0.37 respectively. There are several factors to consider when choosing the winter species for silage production, and future studies can fully elucidate these factors.

The Brazilian livestock activity is undergoing constant evolution, and aiming at its maximum efficiency, it is necessary to have available to the animals food in quantity and quality all the year. To this end, the cultivation of winter forage is carried out. The present study aimed to evaluate the productive and qualitative agronomic traits of ryegrass forage. The experiment was a randomized block design in a 3 x 2 factorial arrangement consisting of six treatments, three plant stands (525, 1050 and 2095 plants m-2) associated with two successive cutting times (vegetative and full vegetative), and four repetitions. There was no interaction between population stand and cutting times for the variables studied. The stand of 525 plants m-2 had a higher participation of green leaves (50.52 %), higher digestibility of the whole plant dry matter (84.81 %) compared to the stands of 1.050 and 2.095 plants m-2, and dry biomass production per unit area equivalent to the others (6087, 7243 and 6989 kg ha-1, respectively). The first harvest season presented higher participation of green leaves and better leaf/stem ratio, 58.62 % and 3.41 % respectively, as well as higher digestibility of green leaves (77.26 %) and stem (80.82 %).

Maize has great economic prominence in national and international agribusiness, being used for various purposes such as grain use and in the form of bulky (silage). This study aimed to evaluate the agronomic characteristics of twelve maize hybrids for silage production in Inconfidentes-MG. Twelve hybrids were used: 20A78PW, 2B512PW, 2B533PW, 2B688PW, 30F53LEPTERA, AG8740-PRO3, DKB345-PRO3, DKB363-PRO3, LG3055-PRO3, LG6036-PRO3, MAXIMUS-VIP3, and MG652PW. The treatments were implanted in a randomized block design (CBD) containing three repetitions. The experimental plots consisted of four lines of five meters in length and 0.8 m spacing between rows, with the two central lines as useful areas. The parameters evaluated were green matter productivity, dry matter productivity, plant height, ear height, average stalk thickness, cutting window, flowering, and cycle. The hybrids 20A78PW; 2B533PW; DKB345-PRO3, and DKB363-PRO3 presented the highest cut-off window values in relation to the others. LG3055-PRO3 hybrid presented the smallest cut-off window. The hybrids 30F53LEPTERA, AG8740, DKB345-PRO3, LG6036-PRO3, and MG652PW presented the highest plant height values. No statistical difference was observed between the hybrids for the variables: green matter productivity, ear height, and stalk thickness. Hybrids AG8740, DKB345-PRO3, LG6036-PRO3, and MG652PW obtained the highest dry matter productivity values. Hybrids 20A78PW, 2B533PW, DKB345-PRO3, and DKB363-PRO3 presented the lowest male and female flowering time. Hybrid DKB345-PRO3 stood out, showing great potential to be recommended and cultivated by silage producers.

Aim: To study the effect of boron on quality parameters and micronutrient uptake of groundnut in coastal sandy soils. Study Design: The experiment laid out in randomized block design with three replications. Place of Study: At College Farm, Agricultural College, Bapatla, Guntur. Methodology: After the preliminary layout, the TAG-24 variety of groundnut was used as a test crop, with a spacing of 30 cm x 10 cm in the experimental site. Plant samples were collected at 45, 90 DAS, and harvest. Plant samples were shade dried and kept in hot air oven at 75°C until a constant weight was obtained. Samples were powdered and then analysed for micronutrients using standard chemical procedures. Results: Protein content, boron content and uptake of micronutrients viz., iron, zinc, manganese, copper and boron were significantly improved with the application of boron in groundnut. Oil content and oil yield were not significantly influenced by the application of boron. The highest value of all these parameters were recorded in T4 (RDF + soil application of Borax @ 12.5 kg/ha). Conclusion: Application of boron along with RDF improved the nutritional quality of groundnut in coastal sandy soils.

Development of maize (Zea mays L.) cultivars with high grain protein and oil concentrations and an appropriate amino acid composition, without losses in grain yield, represents a challenge in breeding programs. The objective of this work was to study the nutritional quality of ten Brazilian maize populations evaluated in three environments. A randomized block design with six replications was used. Ear yield and the concentrations of protein, oil, serine, glutamic acid, alanine, leucine, tyrosine and phenylalanine were evaluated. Individual and combined analyses of variance were performed. Populations diverged for most of the traits. Environmental effects influenced variation for most of the traits, unlike genotype-environment interaction, allowing the selection on the average of environments. Positive association exists among protein and most of the amino acids, when considered on a dry matter basis and there is no association between nutritional quality and yield; therefore, the development of cultivars that are superior for both traits is expected to be feasible.

Sorghum Genotypes

The objective was to assess agronomic characteristics of sorghum genotypes and nutritional values of produced silage. A total of 15 sorghum genotypes were used. Planting was carried out through a randomized-block design with three replications per genotype, totaling forty-five (45) plots. Agronomic and nutritional characteristics, besides the quality of the silage, were assessed. There were differences between genotypes for all characteristics analyzed, with the exception of levels of acid detergent unavailable nitrogen (ADUN), acid detergent unavailable protein (ADUP) and water activity (aw). The assessment of the parameters, except for genotypes 1016013, 1016025, 1016037, 1016039, Volumax and BRS 610, which presented protein level below 7%, showed that the other genotypes can be used for silage production, since they have a good profile of fermentation and in vitro dry matter digestibility; however, genotype SF15 is the most favorable one for silage production due to its little participation in the neutral detergent fiber fraction.

Light Color

Microgreen is a functional plant that is beneficial for human health. Microgreen is a type of cultivation that can be harvested at the nursery stage. In fact, another issue is that it is increasingly difficult to find agricultural land owned by the community, especially in urban areas, so that only a few people cultivate crops. This problem can be overcome by developing a microgreen planting system that is supported by a hydroponic system with artificial lighting for plant growth needs. The experiment was carried out to study about the effect of different types of artificial light color on the nutritional quality of red and green spinach microgreen. The experiment was conducted at the Laboratory of Plant Analysis and Post-Harvest Horticulture, Faculty of Agriculture, Universitas Padjadjaran. The experimental design used was randomized block design with two factors: light color consisting of five levels and plant species consisting of two levels. The light color factor consists of sunlight-control, artificial fluorescent-control, full spectrum LEDs, blue LEDs, and red LEDs. Plant varieties were red and green spinach. The results showed that there was an interaction between light color and plant varieties on nutritional quality of microgreen, such as phenol, flavonoid content, and DPPH radical scavenging activity. The responses of red and green spinach showed different nutritional quality. The red, blue, and full spectrum LEDs gave the best results in each of the tests

Fish is a commodity with high nutritional value. The content of this nutritional value causes fish to be easy to decompose. Therefore, it is necessary to develop and process skipjack fufu (smoked skipjack) fish that improve the quality of smoked skipjack tuna (smoked skipjack) chemically, microbiologically, and with low histamine content. The purpose of this study was to determine the chemical, microbiological, and histamine quality of smoked fish with conventional and non-conventional smoking. This type of research was a quantitative study with a randomized block design. This research is a laboratory experiment with two treatments, namely conventional and non-conventional methods equipped with three replications and three blocks. The results of the test on the third day (H3) and the ninth day (H9) of storage showed that there was no growth of Salmonella sp. and Vibrio cholera in smoked fish samples with conventional (P2) and non-conventional (P1) smoking techniques. There were differences in non-conventional and conventional smoking on the histamine content in smoked fish. Conclusion. There was no growth of Salmonella sp and Vibrio cholera in smoked fish. There is a difference in the histamine content of conventional (P2) and non-conventional (P1) smoking techniques in smoked fish.
