Tillage and nitrogen fertilization effects on yield and nitrogen use efficiency of irrigated cotton
M. Devkota,Christopher Martius,John P. A. Lamers,K.D. Sayre,Krishna Prasad Devkota,Paul L. G. Vlek +5 more
TL;DR: A field experiment was conducted to compare the effects of conservation tillage (permanent raised beds; PB) with conventional plow tillage under three different N application rates (0, 125, and 250) on cotton growth, yield, N use efficiency and N balance in irrigated arid lands of Uzbekistan for two years as mentioned in this paper.

Spectral measurements of the total aerial N and biomass dry weight in maize using a quadrilateral-view optic
Bodo Mistele,Urs Schmidhalter +1 more
TL;DR: In this paper, a tractor-mounted field spectrometer with an oblique quadrilateral-view measuring optic, measuring solar radiation and canopy reflectance in four directions simultaneously, was used to determine the nitrogen status of maize fields.

Magnitude and mechanisms of persistent crop sequence effects on wheat
TL;DR: It is demonstrated that large and significant yield impacts, both positive and negative, can persist for 3–4 years in semi-arid environments as a result of water, N and disease inoculum legacies of Year 1 crop sequence choices.

Effect of Rht Alleles on the Tolerance of Wheat Grain Set to High Temperature and Drought Stress During Booting and Anthesis
TL;DR: Despite the effects of Rht-D1 alleles in Mercia on stress tolerance, the inconsistency of the effects over background and locus led to the conclusion that semidwarfing with GA-insensitivity did not necessarily increase sensitivity to stress at booting and flowering.
Journal ArticleDOI
A sublethal dose of thiamethoxam causes a reduction in xylem feeding by the bird cherry-oat aphid (Rhopalosiphum padi), which is associated with dehydration and reduced performance.
TL;DR: Whatever the observed impairment of xylem feeding is due to a neurotoxic or an antifeedant effect, these results have important implications for commercial crop protection as the behaviour-modifying effects of the sublethal dose of thiamethoxam may change the efficacy of this pesticide throughout the growing season.

Crop loss assessment methods.
TL;DR: In the same year, the director general of FAOFAO convened a Symposium on crop losses to emphasize the need for the development and use of experimental methods to estimate crop losses quantitatively as mentioned in this paper.

TL;DR: This follow-up report summarises pathotype (pt.) assay results from the samples that have been processed to date, and of note is the recovery of wheat leaf rust pt.1, considered to be of exotic origin.
