ABSTRACT Manipueira, a liquid residue obtained from the cassava industrialization, shows high toxicity to the microbial diversity. This study aimed at evaluating the potential of manipueira applied to the soil to control Meloidogyne incognita in soybean. A completely randomized design, in a 2 x 11 factorial scheme, was used, consisting of two application forms of manipueira (single and two applications), in eleven concentrations (0 %, 10 %, 20 %, 30 %, 40 %, 50 %, 60 %, 70 %, 80 %, 90 % and 100 %), with five replications per treatment. Some agronomic traits and parasitism characteristics were also evaluated. The plants that received a single application of manipueira showed a gain of 100.41 % in root length, while the volume and fresh root mass showed gains of 81.52 % and 28.11 %, respectively, with the two applications. Regarding parasitism, the single application was more effective in reducing the number of juveniles in the soil and roots, where the concentrations of manipueira to kill 50 % of the nematodes were 1.65 % and 4.37 %, respectively. Thus, besides being effective in controlling M. incognita, manipueira has a positive effect on the development of soybean and may be recommended as a nematicide and also as an organic fertilizer.

Abstract: The objective of this work was to estimate the damage caused by Meloidogyne enterolobii in okra (Abelmoschus esculentus) and to verify the reliability of the reproduction factor as a suitable measure for selecting resistant okra genotypes. Increasing populations of M. enterolobii - 0, 500, 1,500, 3,000, 5,000, and 7,000 eggs and second-stage juveniles (J2) per plant, - were evaluated, in a completely randomized design. The pathogen showed a parasitism pattern similar to that of M. incognita, causing a significant decrease in morphological and agronomic traits. The pathogen reproduction factor should be used in the selection of okra genotypes for tolerance to M. enterolobii, in populations above 3,000 eggs or J2.

Azotobacter chroococcum based biofertilizers have been widely used in the production of environmentally agriculture. For commercial scale, cheap growth media for Azotobcter inoculant  will affect the quality and price of liquid biofertilizer. Growth medium should support cell proliferation as well as its  nitrogen fixation and phytohormone production.  The objective of this study was to determine whether  liquid organic fertilizer (LOF) containing low N can be used as a medium for scaling up  A. chroococcum inoculant without lowering the survival of bacteria and its activity in N2 fixation and phytohormones production. LOF generally contains a complete nutrient although in a small quantities. Experiment was set up in completely randomized design which tested two types of commercial LOF. The results showed that both of  LOF were only able to support cell growth up to 72 hours and at 96 hours cell viability began to decline compared to the control medium,  free-N Ashby. At 72 hour total N and cytokinin  concentration in LOF was lower than those in Ashby media. This study revealed  that LOF  could be used as A. chroococcum growth media, but without optimization of its composition, cell density and cytokinin content would be lower than those of inoculant  in Ashby Media.

<p>Mungbean is one of the strategic annual food crops that needed by Indonesian people because of the high protein and minerals. Production of mungbean in Indonesia always decreases. Cultural improvements are needed to increase productivity i.e by appropriate fertilization and plant density. The experiment objective was to find out the optimum dosage of organic fertilizer and plant density for the growth and yield of mungbean. The experiment was carried out using factorial completely randomized design (CRD). The first factor treatments were organic fertilizer which consisted of 0, 5, 10, 15, and 20 ton ha<sup>-1</sup>, while the second-factor treatments were planted density which consisted of 1 and 2 plants in the hole. Organic fertilizer of 5 ton ha<sup>-1</sup> gave the best result for plant height, number of branches, flowering age, number of pods, fresh weight and dried straw, weight of 100 seeds, number and weight of seeds, small of seeds number and P nutrient uptake of the plant. The 2 plants per hole gave the best result for branches number, pods number and number of small seeds. Application of 5 ton ha<sup>-1</sup> organic fertilizer and 1 plant per hole gave better yield. No interaction of organic fertilizer and plant density to mungbean growth and yield.</p>
