        Gazania, belongs to the family Asteraceae, is widely grown in gardens and other environments. The purpose of this study was to evaluated the effects of sodium nitroprusside and potassium silicate treatments on the growth and flowering of gazania. For these purposes, a completely randomized design was used, with three levels of sodium nitroprusside (SNP) (25, 50 and 100 μM/l), potassium silicate (PS) at the concentration of 25, 50 and 100 mg/l and control. Some important traits such as fresh and dry weight of shoot and root, number of flowers, root volume, longest root length, plant height, cell membrane stability index, petiole carotenoid, leaf chlorophyll, protein, superoxide dismutase (SOD) and peroxidase (POD) enzyme activity and flower longevity. It was observed that plan that shoot fresh/dry weight, flower number, root length, plant height, carotenoid, leaf chlorophyll was increased under 100 mg/l PS treatment. The results suggest that the application of 50 μM/l SNP has favorable effects on the raise root fresh/dry weight, root volume, cell membrane stability index, protein, SOD and POD activity. Over the growth stage, 50 mg/l PS was found to be the best treatment to maintain flower longevity with 7.2 days. Manuscript profile

        In order to determine the effect of potassium silicate solution with elements of macro and micro elements on agronomic traits of rice, Tarom, a field experiment in paddy fields Galogah city - Village marbles of the crop year 2014 was conducted. The results showed that the highest plant height (013/180 cm) to 2 liters per hectare and no interaction effects of potassium silicate elements. The results showed that the highest number of tillers (500/57) related to interaction effects and without the element potassium silicate was 2 liters per hectare. Results showed that the total number of seeds (87/134 x) the interaction effects of potassium silicate was 2 liters per hectare and micro and macro elements. The highest number of unfilled grain (50/129 pcs) related to interaction effects of potassium silicate 3 liters per hectare, without the element. The highest number of grain (15/7 x) related to the interaction effects of potassium silicate 0 liters per hectare, without the element and the highest grain weight (23/26 mg) of potassium silicate interaction effects 1 liter per hectare and the element Micro respectively Manuscript profile
