Influence of organic manures, consortium biofertilizer and biostimulants on growth ambrette (abelmoschus moschatus medic.)

The present study was conducted at the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annmalainagar, Tamil Nadu During 2009-11. The experiment consisted of different combinations of organic manures viz., Farmyard manure 37.5 t ha-1, vermicompost @ 7.5 t ha-1, pressmud @ 37.5 t ha-1 and consortium biofertilizers @ 2 kg ha-1 as soil application and biostimulants viz., panchakavya 3 %, humic acid 0.2 %, effective microbial inoculants 1: 1000 as foliar application. The experiment was laid out in Randomized Block Design with 13 treatment combinations in three replications. Significant effects due to vermicompost and FYM were found in all the growth and yield attributes. Highest influence on growth parameters viz., plant height, number of branches, number of leaves and plant spread were registered in the treatment that received vermicompost 7.5 t ha-1 combined with consortium biofertilizer @ 2 kg ha-1 and panchakavya 3 %. With regard to the other growth parameters viz., stem girth, internodal length and dry matter production were recorded the highest in the same treatment.
