Onion (Allium cepa L.) plant growth response to varying levels of leaf and root damages – a preliminary study

Onions (Allium cepa L.) is one of the leading horticultural commodities in Indonesia and is often used as seasoning and traditional medicine. Onion has a high economic value and fluctuating prices so that domestic onion production needs to be improved, one of them with a presence of endophytic bacteria that act as plant growth promoting agent or Plant Growth Promoting Bacteria (PGPB). Endophytic bacteria isolated from the root, leaves, and bulbs. In this research has been tested endophytic bacteria of onion plants from Garut regency which has PGPB factors such as able to dissolve phosphate, and produce HCN. The results obtained 251 isolates of endophytic bacteria. Based on the characterization results, the superior isolates capable of dissolving phosphate with an average diameter of 0.45 cm is isolate II.B.1D.3, and 11 isolates capable of producing high HCN. These isolates can be used as PGPB agents so that they can be useful in increasing plant growth and onion production and biocontrol in suppressing pathogens. Keywords: PGPB, endophyte, onion, phosphate, HCN

SUMMARYNitrogen deficiency severely limits production of the bean–maize association grown by small-scale farmers in upland Peru. Sixty-four bean Rhizobium isolates were evaluated for induction of a plant growth response in pots of soil from the area and 14 of the most promising strains of these were tested on farmers' fields in 13 trials over a three year period. Bean yields were increased by inoculation with at least one Rhizobium strain in seven of the trials, with increases ranging from 0.21 to 0.68 t ha−1. Bean yields were not increased by the application of 120 kg N ha−1 to the intercrop. Maize yields were increased by Rhizobium inoculation in nine of the 13 trials by between 0.34 and 1.85 t ha−1. Maize responded to nitrogen fertilizer on the same nine farms. This Rhizobium selection strategy, although laborious, was effective in identifying strains that can be recommended for use as inoculants by farmers in the region.
