ChileanJAR

Yield and quality of garlic (Valenciano Rosado) was studied at La Platina Experimental Station. Nitrogen was applied at 0 - 75 - 150 and 225 Kg/ha of N as chilean nitrate (sodium-potassium nitrate, 15% N) with four different plant populatiom: 500.000 - 666.000 - 1.000.000 and 1.333.000 plants per ha.
Yield was affected by a significant interaction between nitrogen level and plant population. Maximun yield and quality (size) of garlic bulbs was obtained with 150 Kg of N and 1.000.000 plants per ha.
Yield and size of bulbs increased when 666.000 plants /ha or more were fertilized, particularIy with 150 and 225 Kg of N/ha. High plant population, i. e. 1.000.000 or 1.333.000 plantsjha improved total yield but size of bulbs decreased.
When low populations were fertilized with the different nitrogen levels, ranges of 7.4 to 12 ton/ha, were harvested, with 65 to 85% of marketable production.
