Abstract/ Executive Summary:

Among different Vegetables-DS Aus-T Aman cropping patterns, Tomato-BRRI dhan42-BRRI dhan33 yielded highest REY (37.24 t/ha) in partially irrigated ecosystem.

Keywords: Productivity, Partially irrigated ecosystem

Location: BRRI, Gazipur

Start Date: 01-07-2011

End Date: 30-06-2012

Program Area: Farming System

Non-commodity: Adoption of technology

Objectives:

To evaluate the productivity of Vegetable-DS Aus-T. Aman cropping pattern

Methodology:

The experiment was conducted at east byde, BRRI experimental farm, Gazipur during, Rabi 2010-11, Kharif-I-2011 and Kharif-II-2011season. BRRI dhan33 was transplanted in T Aman season, BRRI dhan42 as direct seeded Aus in Aus season and five vegetables were grown in winter season. Four cropping patterns viz. Spinach-Red amaranth-BRRI dhan42-BRRI dhan33, Potato-BRRI dhan42-BRRI dhan33, Tomato-BRRI dhan42-BRRI dhan33-and Carrot-BRRI dhan42-BRRI dhan33, cropping patterns were evaluated in RCB design with three replications. Recommended management practices were followed for rice and vegetable. Vegetables were established from last week of November to third week of January, 2011. Vegetables were harvested during mid January to 1st week of April. Aus was sown in 2nd week of April and harvested in last week of July. BRRI dhan33 was transplanted on 23 August and harvested on 20 November, 2011. Yield of different crops were compared in terms of total rice equivalent yield (REY). A simple economic analysis was done to evaluate the total productivity of Vegetable-DS Aus-T Aman cropping system.

Achievement/Findings:

Yields of spinach and Red Amaranth was 17.18 and 1.23 t/ha under Spinach-Red Amaranth- DS Aus-T Aman cropping patterns. Red Amaranth yield was low due to low temperature followed by spinach. Potato yield was 17.40 t/ha in Potato-DS Aus-T Aman cropping pattern. Tomato yielded highest (26.97 t/ha) among the vegetables in Tomato-DS Aus-T Aman cropping pattern. Carrot yield was very poor due to edaphic factor in Carrot- DS Aus -T Aman cropping pattern. Highest REY (37.24 t/ha) was obtained from Tomato - DS Aus-T Aman cropping pattern followed by Spinach-Red Amaranth- DS Aus-T Aman (31.76 t/ha) and the lowest from Carrot-DS Aus-T Aman cropping pattern. The highest REY of the Tomato-DS Aus-T Aman cropping pattern resulted highest gross margin (Tk. 510340/ha) which was 15, 74 and 77% higher than those of Spinach-Red Amaranth-DS Aus-T Aman, Potato-DS Aus-T Aman and Carrot-DS Aus-T Aman cropping patterns.
