Responses of tomato hybrid cultivars to soil application of humic acid under greenhouse conditions

Abstract Responses of three tomato (Lycopersicon esculentum Mill.) hybrids viz. 'Luanova', 'Savarona' and 'Tessera' to various doses (0, 0.5, 1.0, 1.5 2.0 g L-1) soil application humic acid (HA) were evaluated in terms plant growth, productivity quality fruits, under greenhouse conditions, during 2011-12 2012-13. In addition improved characteristics, higher values for yield components recorded fruits harvested from plants cultivar compared those other tested, regardless growing seasons. Plants 'Luanova' were, however, earlier fruiting with number per plant. Soil HA presented positive effects on physicochemical irrespective the dose investigated, both at L-1 exhibited better results all cultivars their vegetative reproductive significantly fruits. Conclusively, hybrid was found suitable cultivation conditions while aqueous solution @ substantially resulted production
