The article presents results of the effect of cultivation factors on straw yield of Shirudi paddy variety in irrigated podzol-gley-yellow soils of Lankaran-Astara region. It was noted that the planting time of seedlings, the seedlings rate per hectare and nutrition conditions, along with the paddy yield, also increased the straw yield compared to the non-fertilized variant. Also, based on the results of three years field experiments, the reasons for increasing the straw yield of Hashimi variety of paddy in all three plant densities and mineral fertilizer rates at seedlings planting in the 1st decade of May and decreasing it at planting in the 3rd decade of May were explained in detail. The straw yield of paddy was significantly lower during the planting period of seedlings in the 3rd decade of May and in the all three seedlings rate per hectare, depending on the plant density, than planting in the 1st decade of May.
