EFFECT OF MOTHER CARROT ROOT WEIGHT AND PLANTING DENSITY ON SEED QUALITY AND YIELD INDICATORS

Abstract

The study investigates how the weight of mother carrot roots and planting density influence the yield and quality of carrot seeds (Daucus carota L.) under the conditions of Uzbekistan. The research aimed to determine optimal parameters for seed production to improve both quantity and quality. Field experiments were carried out in 2024 in Tashkent region using mother roots of different weights and varying planting densities. Three weight groups of mother roots (60–80 g, 80–120 g, and 120–150 g) and three spacing patterns (45×10 cm, 45×15 cm, and 45×20 cm) were tested. Results indicated that medium-weight mother roots (80–120 g) combined with a moderate planting density (45×15 cm) produced the highest seed yield and superior seed quality characteristics, including germination percentage and seed vigor. The findings highlight the importance of balancing plant density and maternal root mass in achieving optimal seed production efficiency.
