Abstract/ Executive Summary:

Equivalent Rice Yield (ERY) is a measuring tool to determine the economy of crop cultivation. This experiment was conducted during 2010-11 at the experimental farm, BRRI, Gazipur. Objective of this study was to increase the resource use efficiency and the system productivity. In evaluation of different cropping patterns in medium highland irrigated ecosystems indicated that highest REY was obtained from Potato-DT Boro-T Aman followed by Potato-T Aus-T Aman and Boro-T. Aus-T. Aman. Potato yield was lower due to late sowing. The highest REY of the Potato-DT Boro-T Aman cropping pattern resulted highest gross return which was 35.33, 38.96 and 34.35% higher than those of Boro-Fallow-T Aman, Mustard-T Aus-T Aman and Boro-T Aus-T Aman cropping patterns.

Keywords: Double transplanting, Potato, Resource use efficiency, System productivity

Location: BRRI, Gazipur

Start Date: 01-07-2011

End Date: 30-06-2012

Program Area: Farming System

Non-commodity: Cropping pattern

Objectives:

To increase the resource use efficiency and the system productivity

Methodology:

The experiment was conducted during 2010-11 at the experimental farm, BRRI, Gazipur. The tested cropping patterns were, CP₁= Boro-Fallow-T Aman (existing), CP₂= Potato-DT Boro-T. Aman, CP₃= Potato-T. Aus -T. Aman, CP₄= Mustard-T. Aus- T. Aman and CP₅= Boro-T. Aus-T. Aman (Photosensitive). The experiment was conducted in a RCB design with three replications. Rice varieties of BRRI dhan29 was used in CP₁ and BRRI dhan28 was used in CP₂and CP₅. BR26 was used in T. Aus and BRRI dhan46 and BRRI dhan49 were used in T. Aman,.Potato and mustard varieties, Asterix and BARI Sorisa-14, respectively, were used in the experiment. The yield of each crop was converted to REY (rice equivalent yield) for comparing the system productivity. Utilization of resources like labor and inputs was recorded for calculating the variable cost and market price of the output at maturity was collected for determining the economic return.

Achievement/Findings:

Yields of potato were 12.50 and 12.20 t/ha under Potato-DT Boro-T Aman, and Potato-T Aus-T Aman cropping patterns. Potato yield was lower due to late sowing. Yield of mustard was 0.64 t/ha. Yields of Boro rice were 6.23, 5.00 and 5.50 t/ha under Boro-Fallow-T Aman, Boro-T Aus -T Aman and Potato - DT Boro-T Aman cropping patterns. Yields of T Aman rice ranged from 4.41 to 6.40 t/ha under different cropping patterns. Highest REY was obtained from Potato-DT Boro-T Aman and Potato-T Aus-T Aman cropping patterns (19.53 and 16.70 t/ha, respectively) followed by Boro-T Aus -T Aman (12.82 t/ha), Boro-Fallow-T Aman (12.63 t/ha) and the lowest from Mustard –T Aus-T Aman (11.92 t/ha) cropping patter. The highest REY of the Potato-DT Boro-T Aman cropping pattern resulted highest gross return (292.95 Tk /ha) which was 35.33, 38.96 and 34.35% higher than those of Boro-Fallow-T Aman, Mustard-T Aus-T Aman and Boro-T Aus-T Aman cropping patterns.
