Your course endures a lot of punishment. And when you're sowing or overseeding, the last thing you need is to lose seedlings to the onslaught of soilborne disease. That's why each and every seed in the Guardian range has been precision coated with a fungicide and polymer treatment, enabling them to emerge and establish much more reliably than ordinary seed. There are five precisely formulated m...

To assess potential effects of seed limitation, characteristics of invader species and characteristics of established plant communities on recruitment success, we conducted a split-plot experiment factorially combining three weeding treatments corresponding to increasing successional age (regular weeding < cessation of weeding after three years < never weeded since sowing) with two seed limitat...

Wild pistachio forests in terms of the harvesting of various types of products and in terms of energy production and fuel wood are severely exposed to destruction. One of the effective methods for preserving and developing these forests is helping them with artificial regeneration. The purpose of this study was the most appropriate Irrigation, sowing depth and seed cover for seed of Wild pistac...

Seed germination is the initial step of plant development. Seed priming with salt promotes seed germination in tomato (Solanum lycopersicum L.); however, the molecular and physiological mechanisms underlying the enhancement of seed germination by priming remain to be elucidated. In this study, we examined the following in seeds both during and after priming treatment: the endogenous abscisic ac...

Canola sensitivity to delayed sowing date should be managed in such a way that the observance of crop rotation with less reduced in seed yield. The research was conducted to evaluate the yield variation of Hyola401 hybrid, affected by sowing date and nitrogen fertilizer treatments. In this study, the effect of planting date and different levels of nitrogen fertilizers on effective characteristi...

in order to apply suitable methods for sugar beet seed sowing and determine the relation between yield and growth parameters in saline soils, two salt tolerant progeny lines were sown by five methods for two years (1995 and 1996) using a split plot design. growth parameters such as leaf area index, crop growth rate, total dry weight and relative growth rat were analysed. ph and ec of the soil a...

    Abstract:   This research was conducted to investigate the effect of sowing date on growth and yield of five rapeseed (Brassica napus L.) cultivars. The experimental design consisted of four randomized complete blocks (CRDB) in a split-plot arrangement. Four convetional sowing dates (11 September, 27 September, 12 October and 27 October) as main plots and five rapeseed cultivars (RGS00...

The test platform of wheat precision seeding based on image processing techniques is designed to develop the wheat precision seed metering device with high efficiency and precision. Using image processing techniques, this platform gathers images of seeds(wheat) on the conveyer belt which are falling from seed metering device. Then these data are processed and analyzed to calculate the qualified...

Abrus precatorius is the native plant of India and used in many ways in the Indian Ayurvedic system of medicine. This seeds of the species is dormant due to hard seed coat. So the aim of the study is to remove seed dormancy and enhance germination capacity within a short period. To overcome the problem of dormancy, seeds were scarified by seed scarifier, sand paper, hot water treatment, DMSO an...
