[ 1 ] - تأثیر استفاده از ابزار LCC در افزایش راندمان مصرف کود نیتروژن در شالیزار

Nitrogen use efficiency is relatively low in irrigated rice fields because of rapid N losses from ammonia volatilization, the nitrification, surface runoff, and leaching in the soil-flood water system. Since the plant N represents the total N supply of all sources, plant N status will be a good indicator of N availability to crops at any given time. Leaf colour chart (LCC) is a simple portable ...
