Agroproductive Evaluation of Maize (Zea mays L) and Beans (Phaseolus vulgaris L.) Cultivated in Association, in Angonia, Mozambique

This research took place at the Center for Agricultural Research in Mozambique, on red ferrallitic soil, located at the Ntengo Umodzi Agronomy Post, Angonia District, Province of Tete, in 2012-2012. The aim was to evaluate agroproductivity indicators within a crop area of maize and beans in association. A randomized block experimental design was used, with 4 replicas and 5 treatments, consisting of maize plants, variety PAN 53; and beans, variety Diacol, in association, in 20 lots of 8 furrows each. Plant height was evaluated for the two crops. The number of kernels per ear and beans per pod were determined, along with the land equivalence ratio. SPSS 13.0 for Windows was used for statistical analysis of results, and normal distribution of each variable data was checked. Variance analysis was made as well. The Pearson correlation coefficient was performed through the Statistical Analysis System (SAS). The results showed no significant differences in terms of plant height and number of kernels per ears. The land equivalence ratio of the ass

Effect of Five Biostimulants on Sugar Cane Seedling Strengthening and Resistance to Transplantation

Context: The stress undergone by sugar cane during the seedling strengthening stage may be caused by various reasons, such as pest infestation, nutritional deficiencies, and mechanical damages due to manipulation that leads to the loss of genetic material. Objective: To evaluate the effect of five biostimulants on sugar cane seedling strengthening and resistance to transplantation. Methods: A completely randomized experimental design with six treatments (absolute control and samples with the application of azotobacter, phosphorine, improved natural liquid humus, and mineral-fortified liquid humus (BoCalZn)), and four repetitions, was used. The seedlings were placed on a 60-well tray filled with a mix of soil and filter cake. Seven foliar applications were made between days 7 and 56 following transplantation. Plant height and thickness, foliar area, root length, number of active roots, and fresh and dry weights were evaluated 50 days after. For evaluation of resistance to transplantation, the strengthened seedlings were placed in the field, and 45 days later, their survival percentage was determined. Results: The positive effects of the biostimulants applied were observed on the morphophysiological indicators. Conclusions: The application of biostimulants showed the positive effect on the morphophysiological indicators evaluated. The best transplantation resistance of the mineral-fortified liquid humus (BoCalZn) was observed in field conditions

Effect of Bio-Organic Alternatives in the Agronomic Response of Onion on Los Angeles Farm

Context: Onion (Allium cepa L.) is an edible bulb that ranks, as a green vegetable, third in terms of harvested area. In general terms, world production of this crop is made intensively, with a broad application of agrochemicals, which threatens agricultural sustainability, health, and protection of the environment. Aim: To evaluate the effect of bio-organic alternatives in the agronomic response of onion. Methods: A randomized block experimental design with seven treatments was used (absolute control and samples with natural liquid humus, improved liquid humus, fortified liquid humus, fortified liquid humus, plus Phosphoric inducer BayFolan Forte, FitoMas E), and four repetitions. The treatments were made every seven days, starting seven days after the plantation of bulbs. Plant height, pseudostem thickness, leaf number, bulb diameter, and crop yield were the indicators evaluated. The main economic indicators of each treatment were determined. Costs, income, profit, and economic effect were calculated. Results: The results show the positive effect of the morphophysiological and yield indicators related to the application of different bio-organic alternatives. The study produced greater profits than the control. Conclusions: The application of bio-organic alternatives showed a positive effect on the morphophysiological and yield indicators evaluated. The fortified liquid humus plus the phosphoric inducer showed the best results, producing the highest profits in the financial assessment

Efecto de cinco bioestimulantes en el fortalecimiento de posturas de caña de azúcar y su resistencia al trasplante

Context: The sugar cane plantlet stage undergoes stress during the strengthening period, which may be caused by various reasons: pest infestation, nutritional deficiencies, and mechanical damages due to manipulation, which bring about the loss of genetic material. Objective: To evaluate the effect of five bio stimulants on sugar cane seedlings strengthening and resistance to transplantation. Methods: A completely randomized experimental design with six treatments (absolute control and samples with the application of azotobacter, phosphorine, improved natural liquid humus, and mineral-fortified liquid humus (BoCalZn)), and four repetitions, was applied.
