The aim was to study the genetic control of agronomic efficiency at low N availability in maize. Experiments were conducted seven environments a square lattice design with 49 hybrids, consisting 48 crosses and one commercial hybrid, evaluated without application top dressing. Grain yields (GYHN) (GYLN) nitrogen dressing assessed, these traits used calculate (AELN) harmonic mean relative perform...

A field study was conducted in northern France over two consecutive years to evaluate the combined effect of conventional tillage (CT) vs no till (NT) with or without cover crops (cc) and nitrogen (N) fertilization on various agronomic traits related to N use efficiency in winter wheat. Five years after conversion of CT to NT, significant increases in N use efficiency, N utilization efficiency,...

Agronomic Efficiency indicated the grain yield production potential of variety in response to applied nutrients. Field experiment was conducted at research Farm Bako National Maze Research Center Western Ethiopia during 2020/2021 order investigate nitrogen and agronomic efficiency various maize genotypes.

Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...

In order to evaluate genetic diversity of grain yield, nitrogen uptake efficiency and selecting superior varieties, a factorial experiment with the based on Complete Blocks design with four replications was carried out in Saatlo agricultural research station, six corn genotypes (single cross 301,370,540,700,701 and Back cross) and three amounts of nitrogen fertilizer (urea) (27 as a control, 11...
