Effects of Sprout Length, Amounts and Times of Nitrogen Application, Transplanting Rate and Depth of Wheat Straw Mulch on the Fall Crop Production of Potato
정식시 아장, 질소의 시용량과 시용시기, 재식거리 및 피복정도가 감자추작에 미치는 영향
Abstract
In order to find out the effect of five kinds of cultural treatments in fall crop production of potatoes the experiments were carried out with Simabara cultivar at Chonan in 1976. Sprouting of dormant seed pieces were induced by soaking in 2ppm GA and 250ppm Ethrel mixed solution for 60 minutes. Seed pieces with longer sprouts at transplanting, and increasing of urea(nitrogen) application from 10 to 30 Kg per 10a resulted better growth, yields, and quality. Application of total nitrogen at one time on 24th July(transplanting date) resulted lower emergence, yields, growth, and quality as compared with divided application on 24th July and 15th August and 5th September. Higher transplanting than 60
