Abstract/ Executive Summary:

The study was conducted at MLT site, Nikli under OFRD Kishoreganj during Rabi season of 2013-14 and 2014-15 to observe the performance of vegetables as intercrop with maize. Four treatments like maize + potato, maize + field pea, maize + red amaranth and sole maize were used in this study. The experiment was laid out in RCB design with six farmers’ field. The highest maize equivalent yield (12.687 t ha^-1) in 2014-15 and 13.29 t ha^-1 in 2013-14) was obtained from maize+potato intercropping and the lowest (7.48 t ha^-1) in sole maize. The highest gross return (Tk.202880 ha^-1) and gross margin (Tk. 115972 ha^-1) were also found in maize+ potato intercropping and the lowest in sole maize.

Keywords: Intercropping, Maize equivalent yield, Gross margin, Haor area

Location: MLT site, Nikli, Kishoreganj

Start Date: 00-00-2013

End Date: 00-00-2015

Program Area: Farming System

Commodity: Maize, Potato, Fieldpea, Amaranth

Objectives:

To observe the performance of vegetable as intercrop with maize in haor area.

Methodology:

The study was conducted at MLT site, Nikli,Kishoreganj during Rabi 2013-14 and 2014-15. The experiment was laid out in a randomized complete block design with six dispersed replications. There were four treatments i.e., maize + potato, maize + field pea, maize + red amaranth and sole maize. The used maize variety was BARI Hybrid Maize-9.The unit plot size was 6m × 5m. The seeds were sown with 75cm × 20cm spacing on 11 November 2014. The maize seeds were used at the rate of 30-35 kg ha^-1. The lands were fertilized as 230-50-100-23-5-1kg, N-P-K-S-Zn-B ha^-1 in the form of urea, triple super phosphate, muriate of potash, gypsum, zinc oxide and boric acid, respectively. All fertilizers were applied as basal after final land preparation. At the same time of maize, potato, field pea and red amaranth were sown. Double row of field pea (L-L: 25 cm and P-P: 8-10 cm) and single row of potato (L-L: 75 cm and P-P: 20 cm) were sown in between the maize row. The red amaranth was sown with broadcasting method. Irrigations were done at three times at 32, 65 and 75 DAS. Weeding and earthing up were done as and when required. The crops were harvested at their maturity viz., red amaranth in 28 December 2013, field pea in 28 January 2014, potato in 3 February 2014 and maize in 5 April 2014. In the next year, harvesting of red amaranth on 30 December 2014, field pea on 25 January 2015, potato on 7 February 2015 and maize on 9 April 2015 was done. The yield of different vegetables converted to equivalent yield of maize. Data on yield and yield contributing characters were recorded and analyzed to examine the treatments effects and the mean differences were adjudged by LSD test (Gomez and Gomez, 1984).
