Agronomic Comparisons of Heirloom and Modern Processing Tomato Genotypes Cultivated in Organic and Conventional Farming Systems

The yield and fruit quality of processing tomatoes (Solanum lycopersicum L.) have increased markedly over the past decades. aim this work was to assess effects organic (OFS) conventional farming systems (CFS) on main agronomic parameters involved in tomato components traits heirloom modern genotypes. Marketable from genotypes, both OFS CFS, showing a difference ?20 t per hectare favor CFS. Total (TY) not improved assessed ?35 observed In systems, highest marketable genotypes due higher number fruits plant, harvest index, nitrogen efficiency (NAE), water productivity. Moreover, growth differences between CFS were leaves average weight, normalized vegetation index (NDVI), NAE. It is noteworthy that improvement terms color brix paralleled by decrease pH systems. According our results, we conclude reduce current gap breeding efforts should be undertaken increase leaf area NAE for better genotype adaptation
