Physiological and Chemical Response of Groundnut (Arachis hypogaea) to Cobalt Nutrition
نویسنده
چکیده
Two field experiments were carried out to study groundnut physiological and chemical response to cobalt nutrition. Experiments were conducted at Research and production statation, National Research Centre, El-Nobaria Beheara Governorate, Delta, Egypt under drip irrigation system. Cobalt added once i.e. 0.0, 4, 6, 8, 10 and 12 ppm. The obtained results indicate that: Cobalt concentrations significantly improve all growth and yield quantity and quality compared with control. Cobalt at 8 ppm gave the highest figures of all nodulation, growth, yield parameters as well as minerals composition endugennous hormone and chemical constituents. Increasing cobalt concentration more than 8 ppm excerted the adverse promotive effect.

Effect of hydropriming on morphological and physiological performance of aged groundnut (Arachis hypogaea L.) seeds
Low viability and poor vigour due to seed deterioration are major problems for successful agricultural production. In this experiment, the ability of hydropriming to ameliorate seed deterioration damage was studied in groundnut. Groundnut seeds were subjected to accelerated ageing for 96 hours at 40 °C and then hydroprimed at 25 °C for 6, 12 and 18 hours. Regardless of duration, hydropriming si...

متن کاملHormonal priming to overcome drought stress and aging damage in groundnut seed (Arachis hypogaea L.)
Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...
