The researchers studied how different planting dates and watering schedules affect the growth and yield of chickpeas. They planted chickpeas on three different dates in May and used two watering regimes. Early planting resulted in higher grain yield compared to medium and late planting, likely because it allowed for a longer growing season. The soil moisture levels at different depths varied depending on the planting date. Overall, the timing of planting has a significant impact on the productivity of chickpeas in the study area.
