Abstract/ Executive Summary:

The experiment was conducted at Lahirirhat FSRD, Site, Rangpur, during 2008-09 to observe the effect of cow dung bio-slurry on the performance of cauliflower production. The highest curd yield per plant (1075 g) was found from Soil Test Based fertilizer dose for HYG and the lowest was obtained from farmer practice. Significantly, the highest curd yield (39.42 t ha^-1) was obtained from T₂= IPNS (5 t/ha cowdung bio-slurry) fertilizer dose for HYG in 2008-09. The lowest yield was (30.42 t ha^-1) obtained from farmers practice. The highest gross return Tk 315360 ha^-1, gross margin Tk.240778 ha^-1 and benefit cost ratio 4.22 was obtained from cowdung bio-slurry. The lowest gross return Tk 243360 ha^-1 and gross margin Tk.183830 ha^-1was found from farmer practice.

Keywords: Cowdung, bio-slurry, Organic manure, Cauliflower

Location: Lahirirhat, Rangpur

Start Date: 00-00-2008

End Date: 00-00-2009

Program Area: Crop-Soil-Water Management

Commodity: Bio fertilizer

Objectives:

To observe the effect of bio-slurry on Cauliflower production.

Methodology:

The experiment was conducted at Lahirirhat FSRD Site, Rangpur during 2008-09. The land was medium high and the soil was sandy loam in texture. The experiment was laid out in a RCB design in three replications in three farmers’ field. There were three fertilizer treatments (calculated by initial soil analysis) in FSRD site in 2008-09. The entire amount of cow dung and cow dung slurry were applied 5 days before final land preparation. The whole of P, K, S, Zn, B and ½ of N were applied during final land preparation. The rest N was top dressed at 20 and 35 DAP. The crop was irrigated at 20 and 35 DAP. Plant protection measures and other intercultural operation were done as and when necessary. The crop was planted on 21-25 November, 2008, maintaining 60 cm X 45 cm plant spacing. The crop was harvested on 1^st week of February to 3^rd week of February in 2009. Data on yield and yield contributing characters were taken and statistically analyzed following MSTAT software package.

Achievement/Findings:

The higher curd yield of cauliflower was obtained from T₂( IPNS (5 t/ha cow dung bio- slurry) fertilizer dose for HYG). Bio-slurry compensated N, P and K requirement of the crops and showed its higher economic performance hence, it may be concluded that ‘IPNS (5 t/ha CD bio- slurry) fert. dose for HYG’ may be the good alternatives for maximizing cauliflower yield and management of soil health.
