There is little information about common bean fertilization in African Savannas. The objectives of this study were as follows: i) to evaluate the common bean yield potential in the environmental conditions of Lichinga, Niassa, Mozambique, and ii) to determine the common bean response to phosphorus and potassium fertilization applied together in order to verify whether the interpretation of soil analysis for the Brazilian Cerrado could be adopted for Savanna soils in Mozambique. The experimental design was a randomized block design in a 5 x 4 x 2 factorial arrangement. Treatments consisted of a combination of phosphorus doses (0, 35, 70, 140 and 280 kg ha-1 of P2O5), potassium doses (0, 50 100 and 200 kg ha-1 of K2O), and different growing seasons (2012/2013 and 2013/2014). The field rainfed experiments were conducted in Lichinga city, province of Niassa. Common bean crops presented high productivity potential in rainfed systems in the environmental conditions of Lichinga, Niassa, Mozambique, reaching grain yields of up to 3,600 kg ha-1 depending on the rates of fertilization with phosphorus and potassium. Common beans responded to phosphorus and potassium fertilization despite high contents of these nutrients in the soil, according to the interpretation of soil analysis for the Brazilian Cerrado. Maximum grain yield in the average of two growing seasons was estimated to occur for 239 kg ha-1 of P2O5 and 141 kg ha-1 of K2O, indicating that further calibration studies for P and K are required for this specific region of Mozambique.

“…The altitude of the region varies from 1000 to 1300 m. According to Köppen classification, the climate of the region is humid temperate (Cwb), with two well distinguished seasons (temperate, rainy summers and dry, cold winters). The region presents average annual rainfall varying between 1000 and 1500 mm, while the average annual temperature is between 20 and 23 °C (Ministério da Administração Estatal, 2005;Mbanze et al, 2015). Rainfall and temperature were monitored during the trial period ( Figure 1).…”

RESUMOThe demonstration of yield potential of crops depends on genetic factors, favorable conditions of environment, and management. The sowing time can significantly affect the common bean grain yield. The aim of this research was to study the behavior of Brazilian cultivars and sowing times on the yield components and grain yield of common bean grown in the environmental conditions of Lichinga, Province of Niassa, Mozambique. The field trial was performed for two growing seasons, using the experimental as a randomized block in factorial 5 x 3 x 2, with four replications. The treatments consisted of the combination of five common bean cultivars (BRS Pontal, BRS Agreste, Perola, and BRS Requinte, developed by Brazilian Agricultural Research Corporation (Embrapa), and a local variety, Encarnada) with three sowing dates (beginning of the rainy season, and 15 and 30 days after), during two growing seasons. The Brazilian cultivar of common beans BRS Pontal was the most productive in all sowing times, followed by BRS Agreste, which was not the most productive only in the second sowing time of 2013/2014 growing season. The cultivar Encarnada, from Mozambique, was the less productive cultivar in all sowing times and in all growing seasons. The best sowing time for common bean cultivars is in the beginning of the rainy season. The use of technologies such as use of seeds of new cultivars, proper sowing time, fertilization, and control of weeds allow significant increase of common bean grain yield in Lichinga, Mozambique.

“…Las negligencias, por su parte, son más frecuentes durante el periodo poco lluvioso (noviembre-abril), alcanzando su mayor eficiencia para iniciar incendios durante marzo y abril, meses que están al final de la época poco lluviosa. Este resultado se corresponde con un estudio realizado en el Distrito de Lichinga, norte de Mozambique, que muestra cómo los meses de septiembre y octubre, los últimos de la estación seca, fueron los que registraron el mayor número de incendios originados por causas antrópicas en todos los años estudiados (Mbanze et al, 2015). También en Colombia, durante el transcurso del año, los períodos en los que más ocurren incendios de la cobertura vegetal son enero-febrero-marzo y julio-agosto-septiembre, que coinciden con las fases mínimas del ciclo de lluvias de diferentes regiones del país (Pabón-Caicedo, 2011).…”

Comprender la evolución de las causas de los incendios permite realizar un trabajo objetivo de prevención. Esta investigación analiza la causalidad de los incendios forestales en Pinar del Río, Cuba (1975-2018). Los análisis se realizaron considerando sub-periodos, meses del año y vegetación afectada. En el periodo ocurrieron 2896 incendios y se quemaron 51 217.75 hectáreas. Los incendios originados por causas antropogénicas, principalmente las negligencias, mostraron una tendencia al aumento en el tiempo, contrario a lo ocurrido para el caso de los rayos. Esta evolución determinó que la época de incendios cambiara de marzo a junio en el sub-periodo 1975-1985, y pasara a presentarse de marzo a mayo en el sub-periodo 2008-2018. No obstante, la época donde más incendios ocurren por cada causa de forma individual no cambió durante los 44 años analizados. Estos resultados permitirán perfeccionar el trabajo de prevención de incendios forestales.
