A study on influence of seed orientation on seed germination of three species of rattans namely, Calamus prasinus, C. stoloniferus and C. thwaitesii made by sowing the seeds at 2 cm depth in vertical (micropyle end upward), horizontal (micropylar end sideward) and in vertical(micropylar end downward) orientations. Maximum germination of 80% in seeds of C. prasinus recorded in inverted position ...

An experiment was conducted to evaluate the effect of different sowing time on seed yield and quality in under used medicinal plant babchi. The study was carried out for 12 months from January to December. Results showed that the seeds sown in November month recorded the maximum seed yield and quality parameters followed by October month than other months. November month recorded the maximum fi...

in order to study the effect of  foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...

An experiment was conducted at Indian Agricultural Research Institute, New Delhi to study the effect of pre-sowing seed treatment using different combinations of magnetic field intensities and time duration, on germination and seedling attributes in North Indian variety of tomato (var. Pusa Ruby). Seeds were exposed to static magnetic fields (SMF) of strength 50, 100 and 120 mT for 5, 10, 15, 2...

this study was carried out to determine the optimal irrigation intervals in sugar beet seed production fields and to evaluate the effects of irrigation at different growth stages of sugar beet seed bearing plants (cv. shirin) on seed qualitative and quantitative characteristics. the treatments were four irrigation intervals including a control (i1) (irrigation at three stages; planting, bolting...

The response of wheat crops to elevated CO2 (eCO2 ) was measured and modelled with the Australian Grains Free-Air CO2 Enrichment experiment, located at Horsham, Australia. Treatments included CO2 by water, N and temperature. The location represents a semi-arid environment with a seasonal VPD of around 0.5 kPa. Over 3 years, the observed mean biomass at anthesis and grain yield ranged from 4200 ...

Freshwater resources in the North China Plain (NCP) are near depletion due to the unceasing overexploitation of deep groundwater, by far the most significant source of freshwater in the region. To deal with the deepening freshwater crisis, brackish water (rich but largely unused water in agriculture) is increasingly being used in irrigation in the region. However, inappropriate irrigation with ...

sowing date and irrigation are two constrain factors for maize production. these factors can be simulated by using ceres-maize model. for this purpose two experiments (each one at two years) were carried out at agricultural research station of gorgan which is golestan province capital. the model was calibrated using three treatments of optimum irrigation and without stress in 2012 and two treat...

Soil moisture and soil temperature affect pre-harvest infection with Aspergillus flavus and production of aflatoxin. The objectives of our field research in Niger, West Africa, were to: (i) examine the effects of sowing date and irrigation treatments on pod yield, infection with A. flavus and aflatoxin concentration; and (ii) to quantify relations between infection, aflatoxin concentration and ...
