Abstract/ Executive Summary:

A field experiment of intercropping grasspea and field pea as vegetable as well as fodder with hybrid maize was conducted at BARI, Gazipur, RARS, Jessore and ARS, Burirhat during rabi season of 2006-07 and 2007-08 to find out suitable intercrop combination and planting system for higher economic return. Along with sole maize Six intercrop combinations were evaluated in the present study. Grass pea and field pea was introduced as 1 row, 2 rows and broadcast between maize normal rows planting system. The experiment was laid out in RCBD in three replication for all the locations. Maize yield was not reduced significantly under intercropping system though the highest grain yield was recorded in sole maize. But in economic point view, among all combinations, grasspea was superior to field pea either as vegetables or fodder yield over the years and locations. Highest mean maize equivalent yield (13.35 and 13.24 t/ha), gross return (Tk 134133 and Tk 105232/ha) and BCR (3.43 and 3.38) was obtain in 2006-07 and 2007-08 respectively from grasspea broadcast between two normal rows of maize(T₂). Two year results revealed that broadcasting of grass pea/fieldpea in between two normal maize rows might be the best combination for the production of grasspea and fieldpea as vegetable as well as fodder crop. Yield data and yield attributes data of the crops were collected and analyzed statistically.

Keywords: Intercropping, Grasspea, Fieldpea, Fodder, Hybrid maize

Location: Gazipur, RARS, Jessore and ARS, Burirhat

Start Date: 00-00-2006

End Date: 00-00-2008

Program Area: Farming System

Commodity: Grasspea, Maize, Fieldpea

Objectives:

To find out the suitable intercrop combination for higher yield and better economic return.

Methodology:

The experiment was conducted at the farm of BARI, Joydebpur, RARS, Jessore and ARS, Burirhat during rabi season of 2006-07 and 2007-08. Seven treatments were as follows: T₁ = Hybrid maize sole (75 cm x 25 cm) T₂ = Hybrid maize normal row (75 cm x 25 cm) + broadcast grasspea T₃ = Hybrid maize normal row + one line grasspea T₄ = Hybrid maize normal row + two line grasspea T₅ = Hybrid maize normal row + broadcast fieldpea T₆ = Hybrid maize normal row + one line fieldpea T₇ = Hybrid maize normal row + two line fieldpea The above treatments were laid out in a randomized complete block design with three replications. The unit plot size was 6.0 m x 4.5 m. Maize seed were sown on November 26 at Joydebpur, November 24 at Burirhat and November 15 at Jessore during 2006 and November 23 at Joydebpur, November 18 at Burirhat and November 22 at Jessore during 2006 with 75 x 25 cm spacing, on the same day grasspea and fieldpea seeds were sown according to treatment.

Achievement/Findings:

From the above results it may be concluded that hybrid maize normal row + grasspea broadcast and hybrid maize normal row + fieldpea broadcast are the suitable combination for this inter-cropping system.
