Tillage systems and nitrogen timings effect on growth, stay green and grain quality in maize (Zea mays L.)

open access: yesSemina: Ciências Agrárias, 2019
Nitrogen (N), being mobile in soil is exposed to various losses owing to unwise use of nitrogen fertilizer, and conventional soil and crop management practices which can be minimized by temporal nitrogen application and different tillage practices.

Reduced stomatal frequency with rising elevation for Kobresia royleana on the Tibetan Plateau

open access: yesGlobal Ecology and Conservation, 2020
Knowledge about within-species variation in stomatal frequency with varying elevation at very high elevations is rare, which is crucial for us to understand how alpine plants are adapted to the extreme environment.
