Study of growth, phenology and bulb yield in garlic (Allium sativum L.) genotypes under Malwa plateau of Madhya Pradesh

Abstract

The present field experiment entitled “Evaluation of different genotypes of garlic (Allium sativum L.) under Malwa Plateau of Madhya Pradesh” conducted at College of Horticulture, Mandsaur, (M.P.) during the Rabi season 2018-19. The investigation was carried out with 25 genotypes includes 17 local collections and 8 released varieties were studied. The research experiment was laid out in simple Randomized Block Design in three replications during the year 2018-19. The analysis of variance revealed significant difference in all the growth parameters among the genotypes. However, the genotypeT4 G-282 was recorded highest leaf area (31.29, 64.42, 85.85, 159.88 and 167.88 cm2 plant-1), leaf area index (0.32, 0.5, 0.82 and 1.09), leaf area duration (4.79, 7.51, 12.29 and 11.56 cm2 day-1) at all the growth phases of the plant. Maximum CGR and RGR recorded in the genotypes T15 MDS local-6 at 30-60 DAS (0.64 and 35.71), T4 G-282 at 60-90 DAS (1.65 and 66.81) and at 120-harvest (6.09 and 144.19), while T10 MDS local-1 at 90-120 DAS (2.98 and 86.87). The genotype T4 G-282 is superior in chlorophyll content (56.53, 68.03, 88.90, 91.79 and 83.40 SPAD), fresh weight of plant (8.57, 17.12, 56.36, 93.50 and 132.47 g) at 30, 60, 90, 120 and harvest respectively, and maximum bulb yield (173.04 q ha-1). In the phenological parameters, genotypes T21 Ratlam local (4.00), T17 MDS local-8 (4.00) and T3 G-50 (4.00) were found to be early emergence, T4 G-282 (6.00) early germination andT25 Neemuch local-3 (138.00), T24Neemuch local-2 (138.00) early mature as compare to other genotypes.
