The objective of this paper was to evaluate the influence of indigenous and inoculated rhizobia and ammonium sulfate fertilizer on growth and mineral composition of  the herbaceous legumes, Calopo (Calopogonium mucunoides), Ea Ea (Desmodium heterocarpon subsp. ovalifolium) and Kudzu (Pueraria phaseoloides), which are commonly used as forage plants and cover crops in Brazil. The treatments did not exhibit differences for total biomass of nodules. Lime application along with basic fertilization (without N) permitted nodulation and full growth and development of forages with native rhizobia.

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.

In the present study the effects of Rhizobium inoculation and lime application on the mineral composition (N, P, K, Ca, Mg, Fe, Mn, Cu, Zn, B) of red clover (Trifolium pratense L.), in very acid soil were evaluated. Inoculation with Rhizobium leguminosarum bv. trifolii significantly increased shoot dry weight (SDW) of red clover plants (three times greater), as well as N, Mg, Fe, Mn and Cu contents in plants compared to the control. Application of lime and Rhizobium together, depending on the lime rate (3, 6 or 9 t ha-1 of lime) and the cut, increased SDW significantly, but decreased the contents of N, P, K, Mg, Mn, Zn and B in plants. Regardless of the changes, in all treatments in both cuts, contents of N, K, Ca, Mg, Mn and Zn in plants were among sufficiency levels (Mg content was elevated in the second cut), while Fe content was mainly high, as well as Cu (in the second cut). Contents of P and B in plants were somewhat lower than sufficiency levels, but above critical level. Therefore, red clover can be grown with satisfactory yield and mineral composition in acid soil with Rhizobium inoculation only, but the application of P and B fertilization is desirable.

ABSTRACT This research aimed to evaluate the yield and economic viability of three crop cycles of the banana cv. ‘Prata Anã’ in association with perennial herbaceous legumes, natural vegetation, or compared with the conventional management. The research was conducted using a complete randomized block design with split-split plots and four replicates. The plots were formed by four irrigation depths: 50, 75, 100 and 125% of crop evapotranspiration, and the subplots by cover crops (Calopogonium muconoides, Pueraria phaseoloides, and natural cover without N addition) or no cover crops with addition of N fertilization (conventional management). The subsubplots were formed by the second, third and fourth banana production cycles. Yield and economic viability of the cultivation were estimated for a period of seven years. The conventional management promoted greater yield and economic viability in the cultivation of ‘Prata Anã’ banana, due to the N fertilization. Managements with leguminous cover crops were also economically viable, but they should be investigated in combination with N fertilization and compared with the conventional method.

Pasture irrigation under center pivot for beef cattle.  2 ABSTRACT          The aims of this work were to show the pasture irrigation system by center pivot with Brazilian cattle and to discuss the economic feasibility of this technique in different regions of the country. Important parameters to dry matter production of tropical forage plants, as temperature, solar radiation, fertilization, and water requirement were shown Also, the system advantages and disadvantages and a discussion about economic feasibility of this technique were presented. It was concluded that pasture irrigation is a feasible and economical technique to some specific Brazilian regions, depending on appropriated parameters. This work also concludes that just water supply is not enough to assure forage production avoiding reduction in dry production in the winter. KEYWORDS: center pivot, pasture, economic feasibility

Rhizobial Isolates

Biological N fixation in forage legumes is an important alternative to reduce pasture degradation, and is strongly influenced by the inoculant symbiotic capability. This paper evaluates the effectiveness of Calopo (Calopogonium mucunoides) rhizobial isolated from soil under three vegetation covers of an Argissolo Vermelho-Amarelo of the Dry Forest Zone of Pernambuco. An experiment was conducted evaluating 25 isolates, aside from 5 uninoculated controls with 0; 309; 60; 90 and 120 kg ha-1 N, and a treatment inoculated with the SEMIA 6152 strain. The first cut was performed 45 days after inoculation and a second and third cut after 45-day-intervals. Shoot N content was quantified at all cuts. Shoot dry mass was affected by N rates at all cuts. Shoot dry mass increased from the first to the second cut in inoculated plants. There was no difference between rhizobial isolates from the different plant covers for any of the variables. Most variables were significantly and positively correlated.

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.
