The article examines the effect of different seeding rates on plant growth, development, and grain yield of chickpea under rainfed conditions. Field experiments were conducted on typical rainfed sierozem soils using seeding rates of 50, 65, 85, 105, and 125 kg/ha with corresponding planting schemes. The results showed that increasing the seeding rate up to a certain level increased chickpea grain yield. The highest yield, 25.13 c/ha, was obtained at a seeding rate of 278 thousand seeds/ha (105 kg/ha) using the 60×15×12-1 planting scheme. Compared with the control treatment, the yield increase amounted to 16.05 c/ha, or 176.8%. Further increasing the seeding rate to 333 thousand seeds/ha (125 kg/ha) reduced grain yield to 21.33 c/ha. The results demonstrate the importance of optimizing plant density to achieve high and relatively stable chickpea grain yields under rainfed farming conditions.
