increases forage production and economic production in rainfed condition requires attention to agricultural issues such as determination of appropriate sowing depth. so in order to determine the effect of different sowing depths of vetch this experiment was conducted in agricultural research station of maragheh as strip plot based on randomized complete block design with three species of vetch ...

The germination percentage of Acacia catechu Willd. seeds were tested with four pre-sowing treatments in the nursery of Bangladesh Forest Research Institute and growth performances of seedlings were determined both in nursery and field conditions. The germination test was conducted both in germination tray and nursery bed filled with mixture of soil and decomposed cow dung at a ratio of 3:1. Th...

wheat, cv. alvand, under late sowing condition and comparison with conventional sowing date was investigated in a field experiment in 2009-2010. the factors were seven levels of priming by sa, including control or untreated seeds, 400, 800, 1200, 1600, 2000 and 2400 µm sa and two sowing dates including conventional sowing date (23 october) and late sowing (22 november). results showed that prim...

BACKGROUND The prevalence of different biotic processes (limiting similarity, weaker competitor exclusion) and historical contingency due to priority effects are in the focus of ongoing discussions about community assembly and non-random functional trait distributions. METHODOLOGY/PRINCIPAL FINDINGS We experimentally manipulated assembly history in a grassland biodiversity experiment (Jena Ex...

For the last five years an average 14,761 ha of white clover has been grown for seed, with 77%, 8% and 15% sown in public cultivars, New Zealand and overseas proprietary cultivars, respectively. The area presently contaminated by proprietaries is estimated at 20,000 ha. New Zealand requirements for cultivar-change are more effective than OECD requirements. The five-year break period enables suc...

1 The relative importance of regional species pools and local ecological processes in governing landscape variation in plant species diversity and productivity was evaluated in a Kansas grassland. 2 We examined the impact of multispecies sowing treatments and experimental canopy disturbances on plant species diversity and ecosystem processes along a complex natural gradient of plant standing cr...

Nearly one quarter of New Zealand’s unique vascular plant flora is threatened, and weed invasion is implicated in the decline of more than half of these threatened species. However, there is little experimental evidence showing that invasive weeds have a direct impact on threatened native plants. This study experimentally tested the hypothesis that competition with invasive weeds threatens the ...

Abstract The authors have designed a seed pelleter and combined precision sowing rig, which are the backbone of technology pre-sowing treatment sowing. method is based on operation continuous pelleter, where protective nutritious coating formed around seeds while they move along spiral trajectory. next component rig that performs several technological operations in one pass: laying drip tape fo...

The lack of seedling emergence uniformity in corn (Zea mays L.) is concerning for producers the Midwestern U.S. These believe that just a few hours delay can increase interplant competition and decrease single-plant yield, thus reducing overall crop yield. It speculated occurs due to variation seed size within commercial bag seed, depth placement at sowing throughout field. Due these concerns, ...
