Performance of Garden Pea Relay with T.aman Rice in Fallow- Boro- T.aman Rice Cropping Pattern

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

Abstract/ Executive Summary:

The experiment was executed at Muktagacha and Trishal MLT site during 2014-15 to develop an economically profitable cropping pattern and to increase intensification of cropping by using fallow land before Boro cultivation. The existing and alternate cropping patterns were T.Aman-Fallow- Boro and T.Aman/ Garden pea- Boro rice. T.Aman and Garden pea yield were recorded as 3.87 t ha^-1& 3.61 t ha^-1, respectively at Muktagacha and 3.85 t ha^-1& 3.9 tha^-1, respectively at Trishal in the alternate cropping pattern. In the existing cropping pattern, T.Aman rice yield 3.50 t ha^-1 at Muktagacha and 3.35 tha^-1 at Trishal were recorded for the same period of time. Rice equivalent yield (17.36 and 18.07 t ha^-1) was maximum in improved cropping pattern. Gross margin (Tk. 123270 and 134210 ha^-1) was also highest in the improved cropping pattern at both locations.

Keywords: Existing pattern (Fallow- Boro- T. Aman), Alternate pattern (T.Aman/ Garden pea- Boro rice), Rice equivalent yield

Location: Muktagacha and Trishal

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Farming System

Commodity: Gardenpea, Rice

Objectives:

To develop an economically profitable cropping pattern and to increase intensification of cropping by using fallow land before boro cultivation.

Methodology:

The experiment was conducted at Muktagacha and Trishal MLT site during Rabi 2014-15. The experiment has three dispersed replications and the unit plot size was 10m x10m. The experiment was initiated with T.Aman as the first crop and Garden pea as relay crop which was sown 10- 15 days before T.Aman harvest. Yield and yield contributing characters of garden pea and two rice crops were recorded. Cost and return analysis was done on the basis of prevailing market price of the commodities. Productivity of different cropping systems was compared in terms of rice equivalent yield (REY). The REY was computed by converting the yield of garden pea into Tk. (value) and then this value is converted into the yield of rice as following REY = ∑ [garden pea yield (kg) x garden pea price (Tk. kg^-1)] / price of rice grain (Tk. kg^-1).
