The effect of planting pattern, mineral fertilizer and biostimulants on plant density and survival of peanut cultivar "Salomat"

Abstract

The article evaluates the effects of planting pattern, mineral fertilizer rates and the biostimulants Oksigumat Ekstra and Rokogumin on seedling density and plant survival of the peanut cultivar Salomat under irrigated meadow-sierozem soil conditions of the Andijan region. In 2021, planting patterns of 70×10-1 and 70×20-1 cm, mineral fertilizer backgrounds of N60P110K40 and N90P165K65 kg ha⁻¹, and biostimulant rates of 1, 2 and 3 L ha⁻¹ were studied. Plant density at emergence ranged from 135.0 to 137.4 thousand plants ha⁻¹ under the 70×10-1 pattern and from 70.6 to 71.4 thousand plants ha⁻¹ under the 70×20-1 pattern. Mean plant survival was 98.98 and 99.36%, respectively. Increasing the mineral nutrition background was associated with a numerical decrease in plant mortality. Biostimulant rates of 2-3 L ha⁻¹ generally provided the most stable plant survival values.
