Seeds Germination

This experiment was conducted to evaluate the recovery and survival of tropical forage legume seeds (butterfly pea, stylosanthes, perennial soybean and macrotiloma) subjected through the digestive tract of cattle and to evaluate the germination of the seeds in feces of cattle. A 50 g of seed mixed with 150 g of mineral supplement offered to the cattle. Each cattle was considered as repetition. The bovine feces collected up to 60 hours after eating the seeds, where the seeds separated by sieves, using water, gloves procedure and tweezers. Later, they counted and divided into intact and swollen. For the germination test of the recovered seeds, 75 seeds per replicate were used (25 in natura, 25 intact and 25 swollen seeds, respectively). For the germination test in fecal plates, the bovine feces collected between 12 and 30 hours after eating the seeds. After 120 days, we evaluated the total amount of plants emerged within the study period (between 12 and 30 hours) and the average number of emerged plants per fecal signs. The results showed that cattle are facilitating the dispersion of butterfly pea, macrotyloma and perennial soybean, but not stylosanthes. The highest survival as the average number of germinated plants in fecal plates achieved by macrotyloma, followed by butterfly pea species and perennial soybean. The cattle were efficient in the pasture colonization process, due to the considerable dispersion of the seeds. This dispersion was not observed for seeds of stylosanthes.

An experiment was carried out to evaluate two temperate forage legumes (Trifolium pratense and Trifolium repens) and two tropical forage legumes (Stylosanthes guianensis and Centrosema molle) for hay intake and digestibility in the cool tropical climate of Vom, Jos, Plateau State of Nigeria. The legumes were planted in the month of June, 2016 and harvested at early-podding stage for hay. Sixteen (16) growing male New Zealand White rabbits were used for the digestibility study. The rabbits were arranged in a Completely Randomised Design and in individual cages measuring 55 cm x 39 cm x 40 cm. Nutrient contents, intake and digestibility in rabbits were determined. Crude protein content was significantly (P<0.01) higher in T. repens (18.38%) compared to T. pratense (16.50 %), whereas S. guianensis produced the least value of 13.83%. The crude fibre content of the hay was significantly higher (P<0.0I) in S. guianensis (37.29 %) compared to the other forage legumes. Dry matter intake was significantly (P<0.01) higher in rabbits fed T. repens (77.88%) compared to T. pratense (76.57%), and the lowest value of 62.97% was obtained in S. guianensis. Crude protein intake was significantly (P<0.01) higher in rabbits fed T. repens (15.05 g d-1) compared to those fed T. pratense (12.71 g d-1), but S. guianensis had the least value of 8.64 g d-1. On the other hand, rabbits fed S. guianensis hay had a higher (P<0.01) crude fibre intake (23.39%). Trifolium repens was significantly (P<0.01) higher in dry matter and crude protein digestibility (64.79 and 85. 88 %), while S. guianensis had lower values of 56.89 and 71.33%, respectively. Trifolium repens also had a significantly (P<0.01) higher total nitrogen intake and retained compared to the other forage legumes. Nitrogen retained in T. repens was 2.40 g d-1 compared to 1.87 g d-1 in T. pretense, while S. guianensis had the lowest of 1.34 g d-1. The temperate forage legume hays were higher in nutrient content, intake and digestibility compared to the tropical legume hays. Therefore, the forage crops may serve as better supplementary feeds for livestock feeding especially during the dry season.

Integration of tropical forage legumes into cropping systems may improve subsequent crop nitrogen (N) supply, but removal of legume biomass for forage is likely to diminish these benefits. This study aimed to determine: (i) under irrigated conditions, the potential N inputs that can be provided by different tropical forage legumes to a subsequent cereal crop; and (ii) the residual N benefits once fodder had been removed. Available soil mineral N following tropical forage legumes lablab (Lablab purpureus), centro (Centrosema pascuorum), butterfly pea (Clitoria ternatea) and burgundy bean (Macroptilium bracteatum) and grain legume soybean (Glycine max) was compared with a maize (Zea mays) control when legume biomass was retained or cut and removed (phase 1). An oat (Avena sativa) cover crop was then grown to ensure consistent soil-water across treatments (phase 2), followed by a maize grain crop (phase 3) in which N uptake, biomass production and grain yield were compared among the phase 1 treatments. To determine N-fertiliser equivalence values for subsequent maize crop yields, different rates of fertiliser (0–150 kg urea-N/ha) were applied in phase 3. Retained biomass of butterfly pea, centro and lablab increased phase 3 unfertilised maize grain yield by 6–8 t/ha and N uptake by 95–200 kg N/ha compared with a previous cereal crop, contributing the equivalent of 100–150 kg urea-N/ha. When legume biomass was cut and removed, grain yield in the phase 3 maize crop did not increase significantly. When butterfly pea, centro and lablab biomass was retained rather than removed, the maize accumulated an additional 80–132 kg N/ha. After fodder removal, centro was the only legume that provided N benefits to the phase 3 maize crop (equivalent of 33 kg urea-N/ha). Burgundy bean did not increase subsequent crop production when biomass was either retained or removed. The study found that a range of tropical forage legumes could contribute large amounts of N to subsequent crops, potentially tripling maize grain yield. However, when these legumes were cut and removed, the benefits were greatly diminished and the legumes provided little residual N benefit to a subsequent crop. Given the large N trade-offs between retaining and removing legume biomass, quantification of N inputs under livestock grazing or when greater residual biomass is retained may provide an alternative to achieving dual soil N–fodder benefits.

Legume sprouts are a fresh nutritive source of phytochemicals of increasing attention worldwide owing to their many health benefits. Nuclear magnetic resonance (NMR) was utilized for the metabolite fingerprinting of 4 major legume sprouts, belonging to family Fabaceae, to be exploited for quality control purposes. Thirty-two metabolites were identified belonging to different classes, i.e., fatty acids, sugars, amino acids, nucleobases, organic acids, sterols, alkaloids, and isoflavonoids. Quantitative NMR was employed for assessing the major identified metabolite levels and multivariate data analysis was utilized to assess metabolome heterogeneity among sprout samples. Isoflavones were detected exclusively in Cicer sprouts, whereas Trigonella was characterized by 4-hydroxyisoleucine. Vicia sprouts were distinguished from other legume sprouts by the presence of L-Dopa versus acetate abundance in Lens. A common alkaloid in all sprouts was trigonelline, detected at 8–25 µg/mg, suggesting its potential role in legume seeds’ germination. Trigonelline was found at highest levels in Trigonella sprouts. The aromatic NMR region data (δ 11.0–5.0 ppm) provided a better classification power than the full range (δ 11.0–0.0 ppm) as sprout variations mostly originated from secondary metabolites, which can serve as chemotaxonomic markers.

ABSTRACT: Find shade-tolerant species is essential to the success of silvopastoral systems, increasingly frequent in recent years. In legumes, which have potential of biological nitrogen fixation, there is a great lack of knowledge when in shaded environments.The cultivation of four tropical forage (Neonotonia wightii, Pueraria phaseoloides, Macrotyloma axilare and Arachis pintoi) was evaluated when submitted to artificial shade levels (30, 50 and 70% shade) and in full sun during water and drought seasons. The design used was in randomized complete blocks in a sub-divided plot scheme with four replications. In the Water-season the Forage Peanuts had higher forage production in full sun (11 ton ha-1 DM), and under shade did not differ from Perennial Soybean, higher than the others in all levels of shade. In Drought-season the forage production was 61% lower than in Water-season. The highest crude protein levels were reported in Forage Peanuts, Tropical Kudzu and Perennial Soybean, 19.0; 18.3 and 18.2% respectively in the Water-season. Forage Peanuts is a good option for use in silvopastoral systems although there is a small reduction in forage production (average of 23.7%). In general, species of fabaceae showed a greater reduction in forage production in the period of water deficit; however, shading at levels of 30% to 50% contribute to mitigation of water shortage. Although, there is a small reduction in forage production, withexception of perennial soybeans in dry season, it is advisable to use tropical forage legumes in silvopastoral systems, since forage quality is not affected by shade.

Cereal-legume intercropping is important in many low-input agricultural systems. Interactions between combinations of different plant species vary widely. Field experiments were conducted to determine yield formation regularities and plant competition effects of oat (Avena sativa L.)–black medick (Medicago lupulina L.), oat–white clover (Trifolium repens L.), and oat–Egyptian clover (T. alexandrinum L.) under organic farming conditions. Oats and forage legumes were grown in mono- and intercrops. Aboveground dry matter (DM) measured at flowering, development of fruit and ripened grain, productivity indicators, oat grain yield and nutrient content were established. The results showed that oats dominated in the intercropping systems. Oat competitive performance (CPo), which is characterized by forage legumes aboveground mass reduction compared to monocrops, were 91.4–98.9. As the oats ripened, its competitiveness tendency to declined. In oat–forage legume intercropping systems, the mass of weeds was significantly lower compared to the legume monocrops. Oats and forage legumes competed for P, but N and K accumulation in biomass was not significantly affected. We concluded that, in relay intercrop, under favourable conditions, the forage legumes easily adapted to the growth rhythm and intensity of oats and does not adverse effect on their grain yield.

ABSTRACT: The objectives of the present project were to evaluate the sanity and germination of tobacco seed samples cultivated in Brazil and to identify potential pathogenic fungi to the culture. Thirty-four representatives samples of tobacco seeds were evaluated through germination and sanity test by the blotter-test. On the germination test, results were expressed in percentage of seedlings considered normal, abnormal and non-germinated seeds. The percentage of seeds germination varied between 54.5 and 90%. According to sanity test, it was verified the incidence of Alternaria alternata, Cladosporium spp., Fusarium spp., and Phoma spp. The incidence of A. alternata varied from 3 to 67%, and Fusarium spp. varied from 0 to 19%. There was significative positive correlation between the incidence of A. alternata and the percentage of seed germination. Species of Alternaria and Fusarium can be potential pathogens to tobacco culture and an alarm for the necessity of seed treatment of the seeds that are transporting these fungi.
