BACKGROUND AND AIMS Early flooding helps control weeds but reduces seedling establishment in direct-seeded rice (Oryza sativa). When combined with appropriate management practices, the use of genotypes that better tolerate flooding during emergence can enhance crop establishment in flood-prone areas. Management options include seed pre-treatment and we tested the influence of pre-soaking for 24...

In order to evaluate the effects of sowing date and intra rows spacing on yield, yield components and some phytochemical characteristics in Roselle, a field experiment was conducted as a split plot layout based on randomized complete block design with three replications in 2013 and 2014 growing seasons. Five sowing dates were considered as the main plots (11th and 30th of March, 14th of April, ...

Soil salinity is considered crucial for seed germination, seedling growth, and crop production in arid semi-arid regions. Seed priming can be an effective solution to improve maize germination under stress. An experiment was conducted study the effect of with NaCl stress on growth variety Arun-2. Before sowing, eighty seeds were soaked 5g/L aqueous 12 hours at 27-degree Celsius. Primed unprimed...

objective: to evaluate the effect of chemical stimuli on germination and seedling growth of caper (capparis spinosa) under drought stress. methods: factorial experiment in a completely randomized design with four replicates per treatment were performed. first factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/l), gibberellic acid levels (500, 250 and 125 ppm), a...

sowing and harvesting date are the most important agronomic factors that we should pay attention to proper date selection for sowing date in order to achieve good crop establishment and to harvest date in order to achieve the best time for crop quantities and qualities ripening. farmers intend to germinate sugar beet seed at minimum environmental temperature. sowing date affects crop canopy dev...

to investigate the effects of sowing date on yield and quality of six forage maize cultivars in rasht region, a field study was conducted in 2010. the experimental design was a randomized complete block using a factorial arrangement with three replications. treatments consisted of four levels of sowing date (22 may, 3, 15 and 25 june), and six maize cultivars (sc 260, dc 370, sc 500, sc 647, sc...

abstractbackground and objectives: black mustard (brassica nigra (l.) koch) is an annual plant belongs brassicaceae. it has a variety of uses in traditional medicine for rheumatic and neurological pain. growth and development and production of medicinal plants, like other plants is influenced by genetic and environmental factors. select the most appropriate planting date and the most favorable ...

Salinity stress is one of the most important abiotic stress factors limiting the plants' growth. Seed priming is known as a method which improves the germination performance in seeds in stress conditions. The objective of this study was to compare the effectiveness of Hydropriming and Halopriming on germination performance of Secale montanum while growing under the NaCl-salinity stress. Hydropr...
