Using unique crop-specific data gathered over 7 years, we study if and how maize-producing farmers in Ethiopia adjust their land allocation decisions response to pre-planting-season weather variations. We show that increased temperatures early the growing season. In addition quantifying a substantial adaptation margin has not been documented before, our also reveals presence of variation-induce...

It is important to understand the characteristics of Japanese larch (Larix kaempferi) seedlings that allow them grow vigorously after planting and quickly exceed height surrounding vegetation, resulting in lower weeding costs. Seven stock types, including bareroot container-grown seedlings, were planted two plots with different mechanical-site-preparation (MSP) methods evaluated for survival, h...

The effects of irrigation and planting pattern on wheat in field conducted at Taian, northern China during 2011-12. The experiments consisted of two planting patterns (single and double rows) and two irrigation levels (0 and 180 mm) resulting in the same plant density (200 × 10 plant/ha). Each experiment plot was 3 m × 3 m in size and replicated thrice in split-plot design. During course of stu...

The Saffron Yield Estimation Model (SYEM) was modified for salinity conditions, cowmanure application and planting methods using two-year experiments data in Badjgah region ofIran. A split-split plot arrangement was conducted in complete randomized block design duringtwo years with irrigation water salinity levels (0.45 (fresh water, S1), 1.0 (S2), 2.0 (S3) and 3.0(S4) dS m-1) as the main plot,...

abstract narcissus species (amaryllidaceae) are highly suitable outdoor ornamental plants and also as cut flower. narcissus is used in folk medicine and is a medicinal plant, because of galanthamine properties. south area of iran such as khouzestan province, is one of the most important areas of producing cut flower of narcissus in winter season. in this research, the effects of planting distan...

Understanding the genetics of lifetime fitness is crucial to understand a species' ecological preferences and ultimately predict its ability to cope with novel environmental conditions. Yet, there is a dearth of information regarding the impact of the ecological variance experienced by natural populations on expressed phenotypic and fitness differences. Here, we follow the natural dynamics of e...
