A study was designed to investigate silage additives’ effect on preference and nutritive value of five weeks re-growth guinea grass by West African dwarf (WAD) goats. The silages of five weeks re-growth guinea grass were made without additive (T1), with cassava peels additive (T2), and with fermented epiphytic juice of lactic acid bacteria in Panicum maximum (FEJPM) additive (T3). The effects of silage additives on preference, voluntary feed intake, growth, digestibility, and nitrogen utilization were assessed using 18 growing WAD goats (BW: 5.88±0.26 kg) in a completely randomized design. Dry matter was significantly (p<0.05) higher in T2 silage (40.70 g/100g) than in T1 silage (39.00) and T3 silage (34.60). Crude protein values were similar (p>0.05) in T1 and T3 silages (10.63 and 10.72 g/100g DM) that were significantly lower (p<0.05) than that in T2 silage (12.54 g/100g DM). The silages of guinea grass had acceptable physical attributes in terms of color, odor, and texture, with pH values ranging from 3.87- 4.97. T1 and T3 silages were rejected, whereas T2 silage was accepted well by the experimental WAD goats. Average daily feed intake (ADFI) was significantly (p<0.05) the highest in the WAD goats fed T2 silage (303.30 g/day), and the lowest (p<0.05) was found in WAD goats fed T1 silage (271.60 g/day). Similar to the ADFI, the highest average daily gain (ADG) was found in WAD goats fed T2 silage (37.25 g/day), and the lowest ADG (p<0.05) was found in WAD goats fed T1 silage (24.50 g/day). Feed conversion ratio (FCR) of WAD goats fed T2 silage (8.15) was superior to those of WAD goats fed T1 silage (13.63) and T3 silage (9.66). Crude protein and dry matter digestibility values were higher (p<0.05) in WAD goat fed T2 silage (68.24 and 63.87%, respectively) than in WAD goats fed T1 and T3 silages. Nitrogen intake and balance were significantly (p<0.05) the highest in WAD goats fed T2 silage (12.41 and 8.68 g/day, respectively), and these variables were similar in WAD goats fed T1 and T3 silages. Nitrogen retention was not affected by the silage additives. It was concluded that cassava peels were better than FEJPM as a silage additive since it improved fermentative quality, acceptability, feed intake, and digestibility of guinea grass silage by WAD goats.

This study examined changes in soil properties under different types of agricultural land-use. This was done with a view to extending knowledge on the nature of soil properties under long-term land-use practices. The study investigated six types of land-use: paddock, continuously cropped, secondary forest, teak, oil palm, and cacao plantations. Soil strength and saturated hydraulic conductivity were determined in-situ at two soil depths (0–15 and 15–30 cm) across the land-use types. Soil samples were collected to determine particle size distribution, bulk density, aggregate stability, pH, organic carbon, cation exchange capacity, total nitrogen, and available phosphorus. The data obtained were subjected to analysis of variance and Duncan's multiple range test was used to separate significant means at p ≤ 0.05. The results showed that land-use types such as forest, cacao and continuously cropped had higher saturated hydraulic conductivity, while soil bulk density was highest under continuously cropped land-use type (1.55 g cm −3 ). The soil aggregates of forest, teak, and oil palm land-use types were more stable, but soil under oil palm land-use had the highest soil strength (5.65 kg m −2 ). Soil pH across the land-use types was slightly acidic to strongly acidic, while soil organic carbon was least in continuously cropped land (3.87 g kg −1 ). The total nitrogen content of soil across the land-use types was high, but the available phosphorus was low. Paddock, cacao, and continuously cropped land-use types had higher cation exchange capacity. The results implied that continuous cultivation led to depletion in soil physical and chemical properties, whereas, afforestation and cultivation of tree crops conserved soil properties better. Therefore, the establishment of tree crop plantations and conservative soil management practices such as manuring, mulching, liming, and conservation tillage were suggested to prevent agricultural lands from degradation in areas with soils under similar conditions.

Cowpea is considered as one of the most important species in Brazil, for presenting essential components to the feeding process, which makes it relevant to identify the physical, chemical and biological conditions that benefit or cause damage to its development. Thus, the objective of this study was to evaluate the effect of inoculation with rhizobia strains in compacted soil on the develo pment and production of cowpea. The experiment was conducted in a greenhouse, in a completely randomized design with six replications, in a factorial 3 × 2, with two inoculation treatments (BR3267 -Bradyrhizobium sp. and the combination of the strains MT8 -Rhizobium tropici and MT15 -R. tropici) and a control with nitrogen fertilization -150 mg dm -3 , using urea as a source, in compacted and uncompacted soil. The evaluations were carried out during the crop cycle (35, 45, 52, 58 and 90 days) after the emergence of plants, determining the Falker chlorophyll content, dry mass of grains, nitrogen content, nitrogen accumulation and crude protein in shoots and grains. All data were subjected to statistical analyses using the SISVAR program, pe rforming the analysis of variance and the Tukey test at the level of 5% probability. The results showed positive effect on plants inoculated with the combination of the strains MT8 + MT15 in compacted soil, in all parameters evaluated, being observed , values similar to or greater than in plants grown in uncompacted soil. Therefore, the use of the combination of strains becomes a promising alternative for the cowpea development in soil with a density of 1.6 Mg m -3 .
