بررسی تاثیر محلول پاشی ذرات نانو و میکرو سیلیسیم بر صفات مرتبط با عملکرد مینی تیوبر سیب زمینی رقم آگریا

In order to compare the foliar application of nano and micro sodium silicate particles on minituber yield of Agria cv., a factorial experiment based on completely randomized design was carried out at greenhouse of Ferdowsi University, Mashhad. Experimental factors were included of two particle size (nano and micro) and concentration at 11 levels (0, distilled water, 100, 200, 300, 400, 500, 600, 700, 800 and 900 mg. L-1). The results showed that distilled water has most positive and significant effect on length and weight of minituber. The use of nano and micro particles of sodium silicate were caused significant changes in minituber diameter, stolon number, number and yield of minituber per plant. But all concentration levels hadn’t same effect. So that up to 400 mg. L-1 of sodium silicate nano particles, foliar application led to increasing number of stolon, number and yield of minituber per plant. Against, up to 500 mg. L-1 of sodium silicate micro particle, increased stolon and minituber number per plant, and also minituber yield has rising trend up to 700 mg. L-1.
