TL;DR: In this paper, a 6-yr study was conducted to determine the effects of tillage system, preceding crop, and N fertilizer on soil water at wheat (Triticum aestivum L.) planting and harvest in a Vertisol.
Abstract: Under rainfed Mediterranean conditions, water economy must be based on a suitable choice of agronomic techniques. A 6-yr study was undertaken to determine the effects of tillage system, preceding crop, and N fertilizer on soil water at wheat (Triticum aestivum L.) planting and harvest in a Vertisol. Tillage treatments were no-tillage and conventional tillage. Preceding crops, in 2-yr rotations, were sunflower (Helianthus annuus L.), chickpea (Cicer arietinum L.), faba bean (Vicia faba L.), fallow, and continuous wheat. Nitrogen fertilizer rates were 0,50,100, and 150 kg N ha -1 applied to wheat only. No-tillage did not provide more water at wheat planting for any of the rotations. Preceding crop effect on soil water content (SWC) at planting was as follows: fallow ≥ faba bean > wheat ≥ chickpea > sunflower. At harvest, SWC was higher in continuous wheat. Only at harvest were there differences among N fertilizer rates for SWC. Besides, measurement of SWC at harvest for sunflower, chickpea, faba bean, and fallow were performed to determine soil water storage and precipitation storage efficiency (PSE) for 2 yr. Soil water storage was higher for rotations with sunflower or fallow. Nevertheless, fallow PSE was the lowest (10%). The mean PSE was 29%. Under the conditions of this study, no-tillage is not more efficient than conventional tillage in soil water accumulation. Fallow is not a useful tool for increasing water availability.

TL;DR: Priming four seed-lots of leek cultivar ‘Winterreuzen’ in PEG solution significantly improved the rate and uniformity of seed germination, particularly in the slower-germinating lots, in both field and glasshouse conditions.

TL;DR: The results suggested that high temperature caused the significant negative influence on wheat genotypes at anthesis stage establishing a direct association of photosynthesis with starch mobilisation, pollen viability and grain yield.

TL;DR: In this article, an 11-year field experiment (2003-2013) with the same maize cultivar and two short-term experiments including different sowing dates and plant densities were conducted at Luancheng Agro-ecological Experimental Station in the North China Plain (NCP).

TL;DR: Conclusively, use of medium density under both sowing dates is an effective strategy for optimal seed cotton and lint yield and increased plant reproductive organs biomass accumulation than other combinations.
