Abstract

This experiment with aims to increase the tuber yield and quality by using sulphonated silicon nutrient solution with S8 and changing the planting arrangement in potato winter cultivation was investigated in Potato Research Station of Ardabil Province, IRAN during 2022. This experiment was carried out based on the factorial experimental design in three factors and three repetitions. The first factor with two levels including: (1) Spring cultivation and (2) Winter cultivation; the second factor consists of two levels: (1) The planting arrangement of one row on one stack, and (2) The arrangement of planting two rows on one stack in a zigzag pattern and the third factor with three levels includes: (1) Spraying on tuber and soil before planting and foliar spraying in three stages of vegetative growth, tuberization and tuber bulking with a dose of 5 liter nutrient solution in 1000 liters of water per hectare, (2) Foliar spraying in three stages of vegetative growth, tuberization and tuber bulking with a dose of 5 liter nutrient solution of S8 in 1000 liters of water per hectare, and 3. Control (without sulphonated silicon nutrient solution of S8) were. The irrigation method was in the form of drip irrigation. During the growth period, plant height, number of main stems per plant, tuber number and weight per plant and tuber yield were measured. By using nutrient solution and changing the planting arrangement (two rows on one stack) increased tuber yield, tuber number and weight per plant, plant height and water use efficiency in winter and spring cultivation.
