Abstract/ Executive Summary:

A field experiment was conducted at Agricultural Research Station, BARI, Burirhat, Rangpur during rabi season of 2013-14 to find out suitable sowing date of maize as an intercrop with. The treatments were T₁= Sole potato, T₂= Sole maize (seed sown), T₃= Sole maize (Transplanted: 14 day’s seedlings), T₄= Maize sown at 14 days after potato planting (DAP), T₅= Maize sown at 28 DAP, T₆= Maize transplanting (14 day’s seedling) at 28 DAP, T₇= Maize transplanting (21 day’s seedling) at 28 DAP. Sole crops produced highest yield. All intercropping treatments gave higher equivalent yield and monetary return than sole crops. Among the intercropping treatments T₆ and T₇ i.e. transplanting maize in potato field with 14 and 21 days old seedling gave significantly higher potato equivalent yields (35.41 and 34.89 t ha^-1), gross return (Tk.354100 and Tk. 348900) gross margin (Tk. 187350 and Tk. 182150) and BCR (2.21 and 2.09).

Non-commodity: Performance

Objectives:

To observe the effect of transplanting maize seedling between potato rows on the performance of potato + maize intercropping.

Methodology:

The experiment was conducted at Agricultural Research Station, BARI, Burirhat, Rangpur during rabi season of 2013-14. The treatments were T₁= Sole potato, T₂= Sole maize (seed sown), T₃= Sole maize (Transplanted: 14 day’s seedlings), T₄= Maize sown at 14 days after potato planting (DAP), T₅= Maize sown at 28 DAP, T₆= Maize transplanting (14 day’s seedling) at 28 DAP, T₇= Maize transplanting (21 day’s seedling) at 28 DAP. The experiment was conducted in RCB design with three replications. The unit plot size was 4.8 m x 4 m. The potato variety Diamant and maize variety BARI hybrid maize 9 were used. Potato was planted on November 21, 2013 with the spacing of 60 cm x 25 cm. Spacing for sole and intercropped maize were 60 cm x 20 cm and 60 cm x 25 cm, respectively. Recommended doses of fertilizer for potato (115-30-125-25-2-1.5) and maize (254-52-110-45) kg/ha^-1 N-P-K-S-Zn-B (Razzaque et. al., 2000) were used. Potato tubers were harvested on February 20, 2014. Data were analyzed statistically and mean separation was done by LSD following Gomez and Gomez (1984).

Achievement/Findings:

Transplanting maize with 14 and 21 days old seedling as intercrop in potato field performed better over seed sown maize intercropping and sole crop in terms of equivalent yield and monetary return.
