The combination of plant growth regulators (GA3 and Gracilaria sp. extract) and several fertilisers in Salak Pondoh fruit production

Plant growth regulators (PGRs) and proper fertilisers are used to increase quality of the Salak Pondoh, such as in plant production, fruit number size. This study aims determine type dosage PGRs best fertiliser production bunch Pondoh. The method was a Factorial Completely Randomised Design (FCRD) with 36 treatments (excluding control) 3 replications. Three were conducted: first, control, no PGR treatment + fertilisation (no fertilisation, manure, NPK). Second, × factorial scheme. Treatment GA3 (50, 100, 150 ppm) Third, scheme used. Gracilaria sp. extract different solvents (n-Hexane, methylene-chloride, ethanol) parameters observed length, area bunch, length fruit. results showed highest bunches found 50 ppm. While, ethanol only increased formation did not width Fertilisation affected form number, bunches, In addition, area, interaction had significant effect on increasing Pondoh production. result 100 ppm manure fertilisation.
