To determine the efficacy of formulations Ca(NO3)2 liq, Ca(NO3)2 sol-1, Ca(NO3)2 sol-2
and Ca(NO3)2 sol-3, as well as the most appropriate dose
of each formulation to induce the growth and yield of tomato (Lycopersicon esculentum Mill.), the
research was conducted in greenhouses, to transplanting a plant per plastic pot
with capacity of 12 L, which were applied 21, 20, 19, 18, 17, 16 and 15 L·ha﹣1 of solution of each formulation more Steiner solution.
The experimental design was randomized complete block with three replicates per
treatment. The best answer tomato was achieved with Ca(NO3)2 líq, followed by that seen with Ca(NO3)2 sol-1 source,
but the best effect on fruit yield and dry weight of the same was observed with
the dose of 15 L·ha﹣1 of Ca(NO3)2 líq and Ca(NO3)2 sol-3,
while Ca(NO3)2 sol-2 and Ca(NO3)2 sol-1 best were the 16 and 17 L·ha﹣1. In
all cases of calcium sources, doses that better effect resulted in the growth
and fruit yield were lower that the recommended commercially, indicating that
for growing saladette tomato variety Rio Grande should use a dose lower that
the recommended to meet the objectives of agricultural sustainability, for the
conservation and improvement of natural resources (in this case the soil and
tomato plants) and improving the environment.
