Yield of maize grain and tropical grass species under intercropping management ...
KICHEL, A. N.; SOUZA, L. C. F. de; SERRA, A. P.; ALMEIDA, R. G. deThis research aimed to evaluate the maize grain yield and forage of grass species under intercropping system using nicosulfuron herbicide. In order to assess the parameters related to maize, a randomized block design was defined. The treatments were arranged in a (5 × 2+ 1) × 2 factorial design with four repetitions resulting in 11 treatments, where maize was cultivated under intercropping condition with differ...
Corn agronomic traits and recovery of nitrogen from fertilizer during crop seas...
GARCIA FUENTES, L. F.; SOUZA, L. C. F. de; SERRA, A. P.; RECH, J.; VITORINO, A. C. T.The objective of this work was to evaluate corn agronomic traits in a cultivation subjected to different N rates, during the fall?winter (off-season) and spring?summer crop seasons, and N recovery from fertilizer. The experiment was set up in a randomized complete block design with four replicates, in a 5x2 factorial arrangement, with the following treatments: five N topdressing rates ? 0, 30, 60, 90, and 120 k...
Dynamic of Phosphorus Fractions in Typic Quartzipsamment Soil Cropped With Bean.
ALOVISI, A. M. T.; SERRA, A. P.; ALOVISI, A. A.; TOKURA, L. K.; LOURENTE, E. R. P.; CARNEIRO, L. F.; SILVA, M. A. C. da; DAVIDE, L. M. C.; SANTOS, S. C.Phosphorus is the most limited nutrient in Brazilian soils for plant growth, resulted of low availability and poor P content in bedrock. The aim of the study was to evaluate the dynamic of P fractions in a sand soil typical Quartzipsamment cropped with common bean under the effects of P and Si-fertilizer rates. The research was carried out in a soil with sand texture and clay mineralogy constituted mainly by ka...
Phosphorus Fractions and Their Transformations in Entisol.
ALOVISI, A. M. T.; ALOVISI, A. A.; SERRA, A. P.; TOKURA, L. K.; DAVIDE, L. M. C.; LOURENTE, E. R. P.; SILVA, R. S. da; TOKURA, W. I.; SOUZA, D. A. deThe availability of phosphorus in the soil is a factor that directly interferes with its absorption by plants. This availability can be influenced by the texture, dose of the phosphate fertilizer and the time of contact with the soil. This study aimed to quantify the organic and inorganic fractions of P accumulated in a sandy soil receiving doses of phosphorus, incubated and grown with rice. The experimental de...
Establishment of nutrients optimal range for nutritional diagnosis of mandarins...
LABAIEDA, M. B.; SERRA, A. P.; MIMOUN, M. B.The aim of this work was to establish for the first time nutrient optimal range (NOR) for mandarins in Tunisia using two methods: Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrient Diagnosis (CND). The study was performed using data from 120 mandarin?s commercial orchards, in several locations in Tunisia. Yield data and leaf nutrient content from 2011 to 2014 cropping season were c...
Performance of Peltophorum dubium under intraspecific tree competition and card...
HEID, D. M.; SERRA, A. P.; DANIEL, O.; MATOS, F. A.; SALTON, J. C.; NOGUEIRA, I. M. B. N.; CREMON, T.; CARVALHO, R. P. de; BOTTEGA, S. P.Peltophorum dubium canbe an alternative of forestry species to be includedin integrated crop-livestock-forestry systemsin tropical region. The aim of thisresearch was to evaluate the performanceof P. dubiumunder intraspecific tree competition and cardinal directions to measure the possibility of introduction in integrated livestock-forestry systems.The experiment was performed in a Nelder Wheel competition, whi...
The effects of crop rotation systems on maize agronomic traits under no-tillage...
SOUZA, L. C. F. de; FREITAS, M. E.; LOURENTE, E. R. P.; SERRA, A. P.; RECH, J.; FROTA, F.; LOUREIRO, G. E. S.The purpose of this research was to evaluate the crop rotations effects on agronomic traits of maize cultivated in spring-summer in optimal (OCS) and dry cropping seasons (DCS). The experimental design was set up in a randomized complete block and the treatments were arranged in a factorial (8 x 2), consisting of 8 crop rotation systems and two cropping seasons (OCS and DCS), with four replications. The followi...
Agricultural management systems affect on physical, chemical and microbial soil...
LOURENTE, E. R. P.; SILVA, E. F. da; MERCANTE, F. M.; SERRA, A. P.; PEIXOTO, P. P. P.; FERREIRA, R. C. F.; ENSINAS, S. C.; NETO NETO, A. L.The purpose of this research was to assess the effects of replacement of native ?Cerrado? vegetation (NV) into croplands on soil chemical, physical and microbial properties. This research was carried out on a farm under Rhodic Hapludox soil with different types of agricultural managements systems, and it was used a NV to compare the systems. The experimental design was set up in completely randomized with five ...
Phosphorus and silicon fertilizaer rates effects on dynamics of soil phosphorus...
ALOVISI, A. M. T.; FURTINI NETO, A. E.; SERRA, A. P.; ALOVISI, A. A.; TOKURA, L. K.; LOURENTE, E. R. P.; SILVA, R. S. da; SILVA, C. F. B. daThe purpose of this research was to evaluate the effects of P and Si fertilizer rates in dynamic of P fractions in clay soil under greenhouse. The research was carried out in a Dystroferric Red Latosol of a very loamy texture from Lavras city, Minas Gerais State, Brazil. The experimental design was entirely randomized, arranged in 4 × 3 factorial design, with four repetitions. The treatments included four inorg...

ROSA, C. B. C. J.; MARCHETTI, M. E.; SERRA, A. P.; SOUZA, L. C. F. de; ENSINAS, S. C.; SILVA, E. F. da; LOURENTE, E. R. P.; DUPAS, E.The purpose of this research was to evaluate soybean agronomic traits performance under row spacing associated with NPK fertilizer. The experimental design was set up in a randomized complete block and the treatments were arranged with factorial concept, consisting of four NPK (02-20-18%) fertilizer rates (0; 200; 400 and 600 kg ha-1) and five row spacing (0.35; 0.45; 0.50; 0.60 and 0.70 m), with three replicat...
