The objective of the work was to evaluate the effect of the application of Rhizobium bacteria in the biomass production of forage legumes. Rhizobiumstrains were isolated and selected from the rhizosphere of five forage species. Characterization and subsequent cultivation were carried out to inoculate plants in a greenhouse. Subsequently, the biofertilizer was prepared to apply it to five forage legumes: C. ternatea, L. leucocephala, C. macrocarpum, M. pruriens and C. cajan. Plants were germinated in petri dishes and on substrate, after 10 days of germination, they were transplanted into Leonards Jugs and watered with distilled water. The plants were placed in a completely randomized design with three replicates. The evaluations were carried out every week measuring plant heightand at the end of the experiment root weigh, dry matter of aerial part and radicular volume. The best values obtained were in M. pruriens which showed from 49 to 50 cm of plant height. For cross inoculation in weight variable was observed that the strains from C. ternatea and L. leucocephala showed the best results with 0.22 and 0.25 g/plant respectively. Although the best data of dry matter of aerial part was observed in L. leucocephalawith 0.40 g, better response of Radicular volume and plant height was observed in strains that came from C. ternatea with 2 mL and 7 cm respectively. In this study it can be conclude that the use of biofertilizers can be an alternative for low-cost forage production, as long as it contains Rhizobium strains capable of associating with legumes and fixing atmospheric nitrogen.

In a field experiment at Beerwah, Queensland, bauxite pellet applied with 4 per cent methyl cellulose sticker and 1 per cent methyl cellulose as a simple sticker for the inoculant were compared with the standard treatments used successfully in a previous series of experiments. These were peat applied with 4 per cent methyl cellulose, and Florida rock phosphate pellet with 4 per cent methyl cellulose sticker. Legumes and Rhizobium strains tested were Desmodium uncinatum and D. intortum, inoculated with Rhizobium CB627, Lablab purpureus (formerly Dolichos lablab), Glycine wightii (three cvs. Clarence, Cooper and Tinaroo), and Macroptilium atropurpureum (formerly Phaseolus atropurpureus), all inoculated with Rhizobium CB756, and Lotononis bainesii inoculated with Rhizobium CB376. All were planted after 2-day and 28-day storage of inoculated seed. The effectiveness of the treatments was checked by nodule counting and by serologically identifying the strains in a random sample of nodules from each treatment. The majority of nodules formed came from the applied inoculants, but there were no differences between the inoculation treatments in nodulation criteria or effect on yield. The experiment confirmed that bauxite is a satisfactory pelleting material for tropical legumes, but the application of the inoculant peat with 1 per cent methyl cellulose leads to equally good nodulation.

To determine whether a lime oy rock phosphate pellet has any beneficial effect on nodulation of tropical legumes two field experiments were done using Centrosema pubescens, Dolichos lab lab, Desmodium intortum, D. uncinatm, Lotononis angolensis, and Glycine wightii cvs. Cooper, Clarence and Tinaroo. At one site the experiment was sod-seeded into a Paspalum-Axonopus sward, at the other it was sown into cultivated soil. The second site was acid and calcium-deficient and lime was deliberately withheld to introduce bias towards a lime pellet response. At both sites each legume was tried separately with two effective Rhizobium strains and the effect of lime or phosphate pelleting was assessed by comparison with inoculation done with Cellofas sticker without pellet. Nodulation was assessed on 100 plants of each species at ages from seven to twelve weeks. At the sod-seeding site Lotononis and D. intortum did not establish, but the remaining twelve legume-Rhizobium combinations showed no benefit in nodulation from lime pelleting. At the calcium-deficient site lime pelleting in comparison with Cellofas inoculation improved nodulation with eight legume-Rhizobium combinations, had no effect with six combinations, and depressed nodulation with two combinations. Rock phosphate pelleting showed no benefit in nodulation in twelve combinations under sod-seeding. At the calcium-deficient site four combinations showed improved nodulation and 12 combinations no effect, but there were no negative effects. Good nodulation resulted from simple Cellofas inoculation at both sites, with the exception of D. uncinatum at Beerwah. Pelleting treatments gave no yield increases with the exception of D. uncinatum at Beerwah where yield was significantly increased by lime pelleting. No evidence in favour of routine pelleting with either lime or phosphate was provided bv these experiments. The superiority of certain rhizobial strains as field inoculants was demonstrated.

Vesicular Arbuscular

After initial screening in sterilized and nonsterilized soils, two vesicular–arbuscular mycorrhizal (VAM) fungi (Glomus pallidum Hall and Sclerocystis microcarpa Iqbal & Bushra) and two compatible cowpea rhizobial strains (JRC14 and JRC29) have been co-selected. The response of cowpea (Vigna unguiculata (L.) Walp) to inoculation with co-selected pairs of VAM fungus and Rhizobium strains was field tested in Jamaica at two locations (soil types sandy clay loam and bauxitic silt loam). Dual inoculations of cowpea increased the pod yield, mycorrhizal infection, nodule formation, and shoot P and N content compared with single inoculations of either VAM fungus or Rhizobium. However, JRC14 when paired with G. pallidum or S. microcarpa showed maximum yield increase (45%) in both soil types. Our work suggests that appropriate pairing of VAM fungus – Rhizobium should be used for field inoculation. Key words: cowpea, rhizobia, mycorrhizal fungi.

Plastic Gears

Research was performed on the friction, wear and efficiency of plastic gears made of modern engineering polymers and their composites both in a clean environment (adhesive sliding surfaces) and in an environment contaminated with solid particles and dust (abrasive), with no lubrication at all. The purpose is to give a general view about the results of abrasive wear tests including seven soil types as abrasive media. At the first stage of the research silicious sand was applied between the meshing gears and the wear of plastic and steel gears was evaluated and analyzed from the point of different material properties (elongation at break, hardness, yield stress, modulus of elasticity) and its combinations. The different correlations between the experienced wear and material features are also introduced. At the second stage of the project the abrasive sand was replaced with different physical soil types. The abrasive wear of gears is plotted in the function of soil types. The results highlight on the considerable role of physical soil types on abrasive wear resistance and the conclusions contain the detailed wear resistance. The results offer a new tribology database for the operation and maintenance of agricultural machines with the opportunity of a better material selection according to the dominant soil type. This can finally result longer lifetime and higher reliability of wearing plastic/steel parts.

This paper discusses the status of food security in Banten Province, Indonesia based on regional and city characteristics. Secondary data is used and is analyzed descriptively covering population dynamics, the population living in poverty, cereal production, disaster risk and soil types. Tangerang Region is found to have the largest population with the greatest number of people living in poverty among the regions and cities in Banten Province. Cereal production is dominated by the regions rather than the cities due to their vast area. Regarding arable land, flooding is the most threatening disaster in the major rice producing areas. In order to identify the distributions of regions and cities regarding food security, three indicator variables of food security dimensions are plotted, namely, cereal normative consumption, proportion of the population living in poverty, and proportion of malnourished babies. The three regions of Pandeglang Region, Lebak Region and Serang Region are grouped together in a less secure group.
