Plant Spacing Combined with Nitrogen Nutrition Affects Loose Flower Production in Rosa gruss-an-teplitz Under Open Conditions

Immobilization of Rose Waste Biomass for Uptake of Pb(II) from Aqueous Solutions

Rosa centifolia and Rosa gruss an teplitz distillation waste biomass was immobilized using sodium alginate for Pb(II) uptake from aqueous solutions under varied experimental conditions. The maximum Pb(II) adsorption occurred at pH 5. Immobilized rose waste biomasses were modified physically and chemically to enhance Pb(II) removal. The Langmuir sorption isotherm and pseudo-second-order kinetic ...

Nitrogen Nutrition of the Pineapple Plant ,

Unpublished studies in the files of the Pineapple Research Institute of Hawaii indicate that under present cultural conditions the .pineapp1e plant displays superior performance with a foliar applied combination of ammonium and nitrate nitrogen than with either form of nitrogen alone. The studies presented here were undertaken to evaluate ammonium nitrate as a nitrogen source under different so...

Effect of biochar on nitrogen retention in soil under corn plant inoculated with arbuscular mycorrhizal fungi

Maintaining the levels of nitrogen in agricultural fields to ensure crop yield performance is challenging due to the complex dynamics of nitrogen transformation in soil. Nitrogen is mainly taken up by plant roots in the form of nitrate, but it is considered as an environmental pollutant that threatens human and animal health. Therefore, it is necessary to use adsorbent compounds to retain nitra...

Influences of irrigation interval,nitrogen fertilization and plant spacing on tomato fruit yield and quality

Effect of Various Hormones and Different Rootstocks on Rose Propagation

A study was conducted to observe the effects of two hormones viz., Indole Butyric Acid (IBA) and Seradix-A on growth and rooting percentage of Rosa bourboniana cuttings. Experiment was laid out according to Randomized Complete Block Design and there were four treatments, replicated four times. In the second experiment two Rosa species i.e. Rosa bourboniana and Gruss an teplitz were selected as ...
