Nutrient absorption march and accumulation of nutrients in developing Roxo de Valinhos fig (Ficus carica L.) tree, cultivated under different water regimes
The nutrient absorption march in fig (Ficus carica L.) trees and other fruit trees has been studied only at the seedling stage, and little is known about nutrient accumulation in perennial plants when the entire life cycle of the plant is considered. To this end, the present study aimed to evaluate nutrient accumulation in the Roxo de Valinhos fig tree, cultivated with and without supplemental irrigation. The split-plot...

Nitrogen and phosphate fertilizers in elephant-grass for energy use
Nitrogen is the mineral element that plants most require. Its deficiency quickly inhibits plant growth. Excessive nitrogen fertilization raises the cost of biomass production. Therefore, there is a need to find the appropriate dose of nitrogen fertilizer that provides greater efficiency in dry matter production. The objective of this study was to evaluate the effects of nitrogen and phosphate fertilizers on the chemical...

Genotypic variability in some sun flower (Helianthus annuus L.) hybrids evaluated in Khordunia under rainfed conditions
Twenty locally generated hybrids of Sun flower (Helianthus annuus L.) hybrids were evaluated in two seasons (2012 and 2013) for yield and yield components at Khordunia area, Blue Nile State under rain fed conditions. A randomized complete block design with six replications was used for laying out the field experiments. The seeds were sown in the second and third week of July in the first and second seasons, respectively...

Prospection and production of Solanaceae species resistant to the root knot nematode
Plant species of Solanaceae family are affected by numerous pathogens worldwide. Among them is the root-knot nematode which hinders the establishment of crops in the field, reducing their production capacity. This work aims to select Solanaceae species tolerant or resistant to root-knot nematode under the climatic conditions of Fortaleza, Ceará. Two experiments were performed. For both, the followings were...
