| Summary: | Chickpea (Cicer arietinum L.) is a cool-season legume, optimally adapted to regions with low to moderate rainfall. In tropical environments, where its cultivation remains underexplored, it emerges as a potential alternative for winter cropping systems. Proper selection of plant population densities can enhance resource use efficiency, making it a viable component of sustainable agricultural systems.
This study aimed to evaluate the agronomic performance of chickpea cultivars under different row spacing in the edaphoclimatic conditions of Northern Paraná, Brazil (Bandeirantes - PR). The experiment followed a randomized complete block design in a 6 × 3 factorial arrangement, comprising six chickpea cultivars (BRS Toro, BRS Cícero, BRS Aleppo, BRS Cristalino, BRS Kalifa, and CP 1605) and three row spacings (40 cm, 50 cm, and 60 cm). Sowing was conducted on March 27, 2020. Evaluated parameters included biometric traits, grain yield, aboveground biomass production, canopy closure rate, and nutritional composition (crude protein and mineral content). Results indicated that 40 cm and 50 cm row spacings significantly increased biomass production (p < 0.05). The BRS Aleppo cultivar, at 40 cm spacing, achieved a mean grain yield of 1055.4 kg ha - ¹, exceeding the global average, along with high crude protein content (24.5%). Additionally, it exhibited efficient canopy closure by the end of the vegetative cycle, suggesting reduced weed competition. In conclusion, BRS Aleppo demonstrates promising adaptation to tropical conditions, with potential for integration into winter cropping systems under high-density planting (40 cm row spacing).
