in order to study the effect of water deficit stress at different growth stages on yield and seed oil quality of rapeseed cultivars, a field experiment was conducted as split-plot in a randomized complete block design arrangement with three replications in 2009-2010 growing seasons in abarkouh in iran. four levels of irrigation were located in the main plot including, (i1) normal irrigation bas...

ABSTRACT- Different soil potassium (K) pools including soluble, exchangeable and non-exchangeable in surface and subsurface soils may be totally used by canola roots at different growth stages under drought conditions. A field experiment was conducted for one growing season (2013-2014) to study K pools changes during growth stages of two rapeseed cultivars under drought. The experiment was arra...

Sulla (Hedysarum coronarium L.) is a new candidate crop for biofuel production. A field trial was conducted in 2018–2020 Pyrgos, Greece, and repeated 2019–2021 to evaluate different row spacings cover crops weed management sulla two-factor randomized complete block design (RCBD) with four replications. Four spacings, namely 76-cm, 51-cm, 38-cm, 19-cm, were assigned the main plots. Three crops, ...

The formation of aerenchyma in adventitious roots is one the most crucial adaptive traits for waterlogging tolerance plants. Pasture grasses, like other crops, can be affected by waterlogging, and there scope to improve through breeding. In this study, two summer-active cocksfoot (Dactylis glomerata L.) cultivars, Lazuly Porto, tall fescue (Lolium arundinaceum Schreb., syn. Festuca arundinacea ...

Shallot (Allium ascalonicum L) is one of the horticultural plants that acts as a natural antioxidant. Shallot's productivity in Indonesia relatively low. It influenced by various factors, which due to attack soil-borne pathogen, namely Fusarium oxysporum. Symptoms oxysporum pathogen are yellow or pale green leaves and more elongated growth. Severe leads plant death. Balanced fertilization biope...

Late-season heat stress (LSH) is a limiting factor for wheat production. Besides, low zinc and poor protein diet usually problem in low-income countries. The primary calorie source such countries prepared from bread. This study aims to mitigate by nitrogen application improve content grain. We did the field experiments as split-split-plot based on randomized complete block design with four repl...

Regular two-level fractional factorial designs are often used in industrial experiments as screening experiments. When some factors have levels which are hard or expensive to change, restrictions are often placed on the order in which runs can be performed, resulting in a split-plot factorial design. In these cases, the hard or expensive to change factors are applied to whole plots, whereas the...

1 Although it is well established that nitrogen and light play major roles in structuring plant communities across the landscape, it is not as clear how they structure communities within forest stands. Virtually nothing is known about within-stand structure of understorey communities of herbs and small shrubs in near-boreal forests. 2 We tested the hypothesis that fine-scale (5–20 m) variabilit...
