TL;DR: In this article, a 3-year field experiment in rainfed Vertisol was designed to study the effects of timing and splitting of N fertilizer on the efficiency of nitrogen in wheat (Triticum aestivum L.).

TL;DR: In this article, three different experiments were designed to study the effects of N fertilizer rate, timing and splitting, and the response to combined application of N and S fertilizer on the quality of durum wheat (Triticum turgidum L.) over a 3-year period in Vertisols under rainfed Mediterranean conditions.

TL;DR: Number of stems per plant appears to be the most influential factor, although further research is required to confirm this and it is not wholly clear to which component of yield this should really be ascribed.

TL;DR: In this paper, a 3-yr field experiment on a rainfed Vertisol was designed to study the effects of N fertilizer timing on the efficiency of N in durum wheat (Triticum turgidum L. var. durum Desf.).

TL;DR: A field experiment was conducted during a 2-year period (2001-2002 and 2002-2003) in Cordoba (Southern Spain) on a rainfed Vertisol, within the wheat-faba bean rotation framework of a long-term experiment started en 1986, to determine the effects of tillage systems [no tillage (NT) and conventional tillage [CT]], on faba bean N 2 fixation as mentioned in this paper.
