Abstract: The experiment was conducted at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand with a view to study the response of different varieties of rabi maize (Zea mays L.) to crop geometriesduring rabi season of the year 2017-18. The experiment consisted of twelve treatment combinations comprised of three varieties viz., V1: HQPM 1, V2: GAYMH 1 and GAWMH 2 and four crop geometries viz., G1: 30 cm x 30 cm; G2: 45 cm x 20 cm; G3: 60 cm x 15 cm and G4: 60 cm x 20 cm. The results revealed that varietal treatment V1 (HQPM 1) recorded significantly higher plant height at harvest. While significantly higher plant dry biomass, crop growth rate and relative growth rate at 30 and 60 DAS were recorded under varietal treatment V3 (GAWMH 2). Among all the crop geometries, treatment G3 (60 cm x 15 cm) recorded significantly higher plant height at 30 DAS, 60 DAS and at harvest. While significantly higher plant dry biomass, crop growth rate and relative growth rate at 30 and 60 DAS were recorded under treatment G3 (60 cm x 15 cm). With respect to grain and straw yield, interaction effect was found significant between different varieties and crop geometries. Among all the treatment combinations, treatment combination V2G2 (GAYMH 1 + 45 cm x 20 cm) recorded significantly higher grain yield (6039 kg ha-1) and treatment combination V1G3 (HQPM 1 + 60 cm x 15 cm) recorded significantly higher straw yield (10882 kg ha-1).
