Potassium fertilization for fresh market potato production in tropical soils
(Agronomy Journal, 2019-11-01) [Artigo]
Potassium (K) is the most taken up and removed nutrient by potato (Solanum tuberosum L.), and has a great influence on tuber yield and quality. This study was performed to evaluate the effects of three rates (100, 200, and ...
Nutrients released by Urochloa cover crops prior to soybean
(Nutrient Cycling in Agroecosystems, 2019-04-15) [Artigo]
Urochloa spp. grow vigorously in the dry-season of the tropics, and have been used successfully to provide abundant surface residue as cover crop for no-till soybean (Glycine max). Nitrogen (N) fertilizer application could ...
Nitrogen source and rate effects on irrigated potato in tropical sandy soils
(Agronomy Journal, 2019-01-01) [Artigo]
A suitable N source and an optimal application rate can improve the N-use efficiency of potato (Solanum tuberosum L.) while minimizing N losses, especially when potato is grown in sandy soils. Three experiments were conducted ...
Impacts of nitrogen management on no-till maize production following forage cover crops
(Agronomy Journal, 2019-03-01) [Artigo]
Crop residue decomposition is slower in no-till (NT) systems, especially in high-biomass systems. Adopting optimum nN management can provide increased soil coverage and synchronize the supply of nutrients with the period ...
Tuber yield and economic result of ‘atlantic’ potato in response to npk fertilizer formulasProdutividade de tubérculos e resultado econômico da batata ‘Atlantic’ em resposta a fertilizantes NPK
(Horticultura Brasileira, 2019-10-01) [Artigo]
The usual application of high 4-14-8 NPK fertilizer rates in the potato planting furrows, independently of the soil fertility or nutritional cultivar requirements, has become a paradigm in Brazil. However, the 4-14-8 NPK ...
