Effect of organic amendments on the water stress resistance of corn varieties during vegetative stage in ultisols
Indian Journal of Agricultural Research, 2022•indianjournals.com
Background Water stress is one of the most crucial limiting factors in maize production on
Ultisols. One solution that could be adopted to solve this problem is applying organic soil
amendment. Methods This study evaluated three varieties of corn: NK-Jumbo, Srikandi
Kuning and Lamuru. The water stress treatment consists of 75% field capacity (without water
stress) and 37.5% field capacity (water stress treatment). The organic amendment consists
of without soil amendment, rice-straw 10 tons ha− 1, biochar 10 tons ha− 1 and rice straw 5 …

Abstract
Background
Water stress is one of the most crucial limiting factors in maize production on Ultisols. One solution that could be adopted to solve this problem is applying organic soil amendment.
Methods
This study evaluated three varieties of corn: NK-Jumbo, Srikandi Kuning and Lamuru. The water stress treatment consists of 75% field capacity (without water stress) and 37.5% field capacity (water stress treatment). The organic amendment consists of without soil amendment, rice-straw 10 tons ha− 1, biochar 10 tons ha− 1 and rice straw 5 tons ha− 1+ biochar 5 tons ha− 1. A factorial, completely randomized design was used in this research.
