The sweet potato is an important food for the population, being rich in proteins, fibers, nutrients such as K, P, Ca, Mg, Fe, Mn, Cu, and bioactive compounds. It is usually cultivated by small producers. In Brazil, the ...

The rate of chromatid breaks was studied in cows with a history of sub-fertility by means of a test based on measurement of the average of breaks induced in lymphocytes of peripheral blood cultures. Fourteen female specimens ...

The objective of this work was to evaluate the effect of the application of organomineral and mineral fertilizers to highly fertile soils on the carbon management index (CMI) and carbon fractions and stock. The experiment ...

A new concept of fertilizer machine is under development and shows as differential individually fertilizer application, that is sources of N, P and K are applied separately for the purpose of improving the distribution ...

Sweet potato (Ipomoea batatas L.) is a versatile crop, but it is often grown in marginal and low-fertility areas, which reflects storage root yields far below its potential. For this reason, balanced liming and fertilization ...

Crop systems and fertilization sources can affect the chemical properties of the soil and, consequently, its fertility. With the aim of evaluating the effect of such management practices, soil samples collected at 0.0-0.10; ...

Fertilization is one of the most effective ways to increase crop productivity, and the use of slow release fertilizers could be advantageous, allowing the assimilation of nutrients as the plants grow. The objective was ...
