Yield of Tomato in Soil Treated with Compost, Amorphous Primary Minerals and Microorganisms

摘要

This research was conducted to determine the chemical condition initial and final of the soil, having been treated with compost, primary minerals amorphous (MPA) and microorganisms (M) as well as response of the hybrid “Moctezuma” of saladette tomato ( Lycopersicon esculentum Mill.). Compost and MPA were applied 30 days before the transplant, the Steiner solution from the transplant and the microorganisms every eight days up to harvest in drip irrigation; the population density was 25,000 plants per hectare, the which they were handled to a stem in separate rows 1.6 meters between they. The experimental design was randomized complete block with four replications and nine treatments. The 25 Mg·ha ﹣1 ) of compost and 6 Mg·ha ﹣1 ) of MPA (T8) were sufficient to yield 114.0 Mg·ha ﹣1 ) with an increase of 9.3% compared to 104.3 Mg·ha ﹣1 ) achieved with Steiner solution. Compost, MPA and M were made that the soil increased the fertility from before transplantation, and until the harvest is continued providing enough nutrients, with the exception to Cl and S, which were not detected after harvest. Deficiencies of Cl and S perhaps were one of the causes of that plants did not produced beyond that achieved with Steiner solution or T 8 ) , this latter that in turn allowed manage more sustainably the soil and plants that with Steiner solution, while with T 8 ) was supplied organic matter and assimilable mineral by plants.
