Abstract

Growth characters in five onion genotypes were compared under direct-seeding and transplanting. Direct-seeding had higher leaf area duration (LAD), crop growth rate (CGR) and leaf area index (LAI) at all stages except at later stages. Among the varieties Bellary Red and Nasik Red realised higher yields and had relatively higher LAD, LAI and CGR and least were in Local White and Telgi Red. Further, under direct-seeding lower leaf area ratio (LAR) and net assimilation rate (N AR) were observed than under transplanting.
