Abstract/ Executive Summary:

The experiment was carried out at TCRC, Joydebpur and Bogra during February to September 2010. The treatments comprised of four methods of N application viz. N1 = 2 splits at 60 DAP and then 60 days interval, N2 = 4 splits at 60 DAP and then 30 days interval, N3 = 6 splits at 60 DAP and then 15 days interval and N4 = 8 splits at 60 DAP and then 10 days interval and three methods of K application viz. K1 = 2 splits equally as basal and 60 DAP, K2= 3 splits equally as basal, 60 and 120 DAP and K3 = whole K applied as basal. Both the factors significantly influenced growth and yield of Panikachu. The highest mean yield of stolon (32.56 t/ha) as well as rhizome (42.54 t/ha) was obtained from the interacting treatment of N3K1 with the highest BCR of 3.74

Keywords: Split Application, NK fertilizers, Panikachu

Location: Joydebpur, Gazipur

Start Date: 01-02-2010

End Date: 01-09-2010

Program Area: Crop-Soil-Water Management

Commodity: Aroids

Objectives:

To work out the proper method of application of nitrogen and potassium fertilizers for obtaining maximum yield of Panikachu.

Methodology:

The experiment was carried out at TCRC, Joydebpur and Bogra during February to September 2010. The treatments comprised of four methods of N application viz. N1 = 2 splits at 60 DAP and then 60 days interval, N2 = 4 splits at 60 DAP and then 30 days interval, N3= 6 splits at 60 DAP and then 15 days interval and N4 = 8 splits at 60 DAP and then 10 days interval and three methods of K application viz. K1 = 2 splits equally as basal and 60 DAP, K2 = 3 splits equally as basal, 60 & 120 DAP and K3 = whole K applied as basal. The twelve treatments combination was laid out in a factorial randomized complete block design with three replications. The unit plot size was 3 m × 4.5 m. The plot was fertilized with a dose of 350-180-250 kg/ha of Urea-TSP-MOP, respectively with 7 t/ha of cowdung. Full dose of cowdung and TSP were applied at final plot preparation and urea and MOP were applied as per treatment wise. The variety used was BARI Panikachu -2.

Achievement/Findings:

Both the methods of application of NK fertilizer significantly influenced growth and yield of Panikachu. The highest mean yield of stolon (32.56 t/ha) as well as rhizome (42.54 t/ha) was obtained from the interacting treatment of N3K1 with the highest BCR of 3.74
