Development of Alternate Cropping Pattern Potato/sweet Gourd-t.aus-t.aman in the Stable Charland of Kurigram District

Chief Scientific Officer & Head, OFRD and Relevant Scientists of OFRD

Abstract/ Executive Summary:

The experiment was conducted in the farmers’ field, during 2013-14 to observe the performance of alternate cropping pattern Potato/Sweet gourd-T.Aus-T.Aman against the existing cropping pattern of Fallow-Boro-T.Aman rice in the char land in Ulipur, Kurigram. The experiment was laid out in RCBD with 6 dispersed replications. Potato variety BARI Alu-25, Sweet gourd variety Local and T.Aus rice variety Parija and and T.Aman rice variety BRRI dhan49, Boro variety BRRI dhan28 were used in the trial. The alternate cropping pattern gave higher rice equivalent yield (24.4 t ha^-1) than that of exsting one (9.46 t ha^-1). Gross return (Tk.395502ha^-1) as well as gross margin (Tk.126892ha^-1) were higher in alternate pattern and) over existing pattern (Tk.153563ha^-1 and Tk.47663 ha^-1).

Keywords: Alternate pattern Potato/Sweet gourd-T.Aus-T.Aman, Existing pattern Fallow-Boro-T.Aman, Gross margin, Char land

Location: MLT site, Ulipur under Kurigram district

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Farming System

Commodity: Potato, Sweet gourd, Rice

Objectives:

To compare the performance of Potato/Sweet gourd-T.Aus-T.Aman against Fallow-Boro-T.Aman rice cropping pattern at char land.

Methodology:

The experiment was conducted in the farmers’ field of the MLT site, Ulipur during 2013-14. The experiment was laid out in RCBD with 6 dispersed replications. There were two treatments viz., F=Existing cropping pattern (Fallow-Boro-T.Aman rice) and FA=Alternate cropping pattern (Potato/Sweet gourd-T.Aus-T.Aman). Potato variety BARI Alu-25, Sweet gourd variety Local and T.Aus rice variety Parija and T.Aman rice variety BRRI dhan49, Boro variety BRRI dhan28 were used in this trial. Potato variety was sown on 02 December, 2013 and Sweet gourd was sown as relay on 15 January, 2014. T.Aus was planted on 10 May, 2014 and T.Aman was planted on August 07, 2014 of alternate cropping pattern. In existing cropping pattern Boro seedling was transplanted during 05 Feb, 2014 and Aman was transplanted on 25 July, 2014. In alternate cropping pattern potato, sweet gourd, T.Aus and T.Aman was harvested at 91, 103 DAP, 74 and 112 DAT, respectively. In existing cropping pattern Boro and T.Aman was harvested at 124 and 115 DAT, respectively. Recommended fertilizer doses were used for all crops. Intercultural operations were done as and when required. At maturity different data were collected accordingly and subjected to statistical analysis .

Achievement/Findings:

Potato/sweet gourd-T.Aus-T.Aman cropping pattern could be easily grown in stable charland. More irrigation water was needed to grow Boro rice in stable char land having sandy loamy soil. On the other hand, it was very easy to grow potato and vegetables in this soil which might provide higher cash return. Therefore, Potato/sweet gourd-T.Aus and T.Aman might be recommended for wider extension in the stable charland.
