Abstract
Field experiment was carried out during the two successive seasons (2015-2016 and 2016-2017) at Sids Research Station, Agricultural Research Center (ARC), Bani Swif Governorate, Egypt, to evaluate the response of some new chickpea genotypes cultivated under Egyptian soil conditions for rhizobial inoculation alone or in combination with foliar inoculation of Pink Pigmented Facultatively Methylotrophic bacteria (PPFMs) as Plant Growth Promoting Rhizobacteria (PGPR). Nodulation status, some vegetative growth and yield parameters were determined. The obtained results cleared that all chickpea genotypes tested were positively responded to the native soil rhizobia and formed root nodules. Rhizobial inoculation alone or in combination with foliar application of PPFMs bacteria (5 L fed-1) scored significant increases in nodule numbers, plant dry weight, yield per plant as well as seed yield at the both seasons as compared to untreated treatments. Using rhizobial inoculation and PPFMs bacteria emphasized the superiority and gave of the highest values at all tested parameters. Generally, the second season gave the highest values at all plant tested parameters as compared to uninoculated ones. Chickpea genotypes GT3, GT4 and GT7 emphasized higher response to cultivated under Egyptian soil conditions and gave higher values for nodules number and dry weight, growth parameters i.e. plant dry weight and plant N-content and yield parameters i.e. yield per plant, seed index and seed yield ton. fed-1 as compared to chickpea variety G195.
Highlights
Rose (Rosa hybrida L.) is the most important member of the Family Rosacea, which contains 200 species and more than 18,000 cultivars (Gudin, 2000), grown as ornamental plant around the world
The aim of the present study is to evaluate the performance of different amino acids on the growth and flowering of rose plants in different soilless culture systems
Phenylalanine acid followed by proline acid significantly increased leaf number/plant, leaf fresh weight/plant, leaf length and width as well as root length compared to the other amino acids under study during both seasons
Summary
Rose (Rosa hybrida L.) is the most important member of the Family Rosacea, which contains 200 species and more than 18,000 cultivars (Gudin, 2000), grown as ornamental plant around the world. Soilless culture system represents a valid alternative to conventional cultivation techniques due to the full control of the inputs that provides, and it is a good technique to grow rose offering guarantees of quality to the market (Nicola et al., 2005). It allows to produce clean material at harvest, and to reduce many washing treatments. The cost of production by the NFT is to the soil grown plants
