Mini tomato production in organic system under greenhouse with partial control of meteorological elements

ABSTRACT The objective of this research was to evaluate the meteorological elements of the environments and the production components of mini tomato crop in organic system in different forms of cultivation, biofertilizer doses and technological levels of protected environments. The research was conducted in completely randomized design in a 3 x 2 x 5 factorial scheme, corresponding to three greenhouses (A - climatized, B - mobile screen and C - fixed screen), two forms of cultivation (pots and beds) and five doses of a commercial biofertilizer (0, 50, 100, 150 and 200% of dose indicated), with five replicates. The treatments affected the analyzed variables, except for biofertilizer doses and interaction of treatments. Air temperature was unchanged among the environments and the mean and minimum relative humidity were within the control range in the climatized greenhouse. The greenhouse with mobile screen showed the best production results for the cultivation in beds and the biofertilizer doses were indifferent for all treatments
