EFFECTS OF NICKEL AND NITROGEN SOIL FERTILIZATION ON LETTUCE GROWTH AND UREASE ACTIVITY

These results are evidences of the effect of root morphology and P-uptake kinetic characteristics on shoot and root growth and on dry matter yield of plants, grown either in soil

Based on the fact that organic fertilization can improve soil quality, we compared the effects of conventional and organic soil management on microbial activity and mycorrhization

Table 2 – Genotype, Year and Genotype × Year effects on total dry matter yield (DMY), stem dry matter yield (Stem DMY) and leaf dry matter yield (Leaf DMY) of Panicum maximum

Thus, it is necessary to maintain a permanent soil cover to improve soil quality and crop yield, with beneficial effects on soil organic matter, microbial activity and

There was a positive and significant correlation between the available Ni levels extracted from the soil with Mehlich-1 and DTPA; in the plant tissue the recovered levels were

The soil samples were used to estimate the soil microbial biomass carbon and nitrogen, soil basal respiration, metabolic quotient and soil enzymatic activity, through hydrolysis

Average values of fresh leaf matter (FLM), dry leaf matter (DLM), stem length (SL), fresh stem matter (FSM), dry stem matter (DSM), fresh root matter (FRM), dry root matter (DRM),

When N fertilization was not applied to either crop, the lettuce MFPI in intercropping decreased by 42.5% compared to the maximum MFPI obtained in intercropping (Figure 1A) and
