Response of six common beans cultivars to phosphate and potassium fertilization in Lichinga, Niassa, Mozambique.

A field experiment was conducted to check out the response of the common bean BRS 293 Pontal to basic fertilization with Phosphorus (P) and Potassium, in the environmental conditions of Lichinga, Niassa, Mozambique. A complete factorial 5x4 was used, with five rates of P2O5 (0, 35, 70, 140, and 280 kg/ha, as Triple Superphosphate) and four rates of K2O (0, 50, 100 and 200 kg/ha, as Potassium Chloride). The experimental area was also fertilized with 90 kg/ha of Nitrogen (N), as Urea, spliced in 23 kg N/ha at planting and 67 kg N/ha 20 days after plants emergency. Each treatment was replicated four time in the field, in randomized blocks (18 m2 each, with five liner of six lineal meters each, spaced 0,45 cm, with nine seeds seeded per meter). At harvest (area of 3 m within the central lines), it was evaluated the plant final stand, degree of lodging, number of pods per plant, number of grains per pod, weight of 100 grains, and productivity. Based in the analysis of the data, it is concluded that maximum productivity, equivalent to 3,616 kg of grains/ha, would be obtained with a combination of 406 kg/ha of P2O5 and 43 kg/ha of K2O. Such rate is above what would be expected, which indicates that new studies would be necessary for better recommendation of P2O5 fertilization in this area

Performance of six common beans cultivars in three different planting dates in Lichinga, Niassa, Mozambique.

A field experiment was conducted in the area of the Centro Zonal Norte do Instituto de Investigação Agrária de Moçambique (IIAM), em Lichinga, Niassa, Moçambique, with the objective of checking out the performance of common beans cultivars in response to local environmental conditions. A complete 6x3 factorial experimental design was used, encompassing six cultivars of common beans (BRS Pontal, BRS Agreste, BRS Perola, and BRS Requinte, developed by Embrapa, Brazil; and two locals, Manteiga and Encarnada), and three planting dates (12/12/2012, 29/12/2012, e 13/01/2013). There was soil cover fertilization at planting (500 kg/ha of the mixed NPK 2-24-12) and after 20 days of plants emergency (130 kg de N/ha). Each treatment was replicated four times in the field, in randomized blocks (18 m2 each, with five liner of six lineal meters each, spaced 0,45 cm, with nine seeds seeded per meter). At harvest (area of 3 m within the central lines), it was evaluated the plant final stand, degree of lodging, number of pods per plant, number of grains per pod, weight of 100 grains, and productivity. The Brazilian cultivars showed higher productivity than the local ones within the studied conditions, especially BRS Agreste, with an average production of 2,387 kg of grains/ha. The best planting date was at the end of December
