Plant density, survival rate, and tillering capacity of rice accession samples

Abstract

The article studies plant density before harvest, the total and productive tiller number, plant survival, and total and productive tillering of 62 rice accessions under the conditions of Khorezm region. Plant density ranged from 125.3 to 284.5 plants/$m^2$, productive tillers from 204.1 to 308.1 per $m^2$, and plant survival from 40.8 to 61.6 %. A strong negative correlation between field emergence and productive tillering (r = -0.80) was found; compensation of sparse stands through tillering did not fully offset yield losses.
