Abstract/ Executive Summary:

An experiment was conducted in charland at the Multi Location Testing (MLT) site Bhuapur, Tangail during 2012-13 and 2013-14 under AEZ-8 to find out the suitable intercropping system of hybrid maize with different short duration vegetables with economic return. The experiment was laid out in RCB design with six dispersed (six farmers’ field) replications. The hybrid maize (ver. BARI Hybrid maize-7), potato (Diamant), spinach (local), red amaranth (BARI Lalsak-1), Radish (BARI Mula-1) were used as the planting materials. Five treatment combinations viz. T1= Sole Maize, T2= 100% Maize (maize paired row) + Potato (var. Diamant), T3= 100% Maize (maize paired row) + Spinach (var. local), T4= 100% Maize (maize paired row) + Red amaranth (var. BARI Lalshak-1) and T5= 100% Maize (Maize paired row) + Radish (var. BARI Mula-1) were studied. Maize grain yield in intercropped combination varied from 5.59-7.62 t ha^-1. But the highest grain yield (8.17 t ha^-1) was obtained from sole maize. Maize equivalent yields in the intercrops situation ranged from 11.39-19.68 t ha^-1 where highest maize equivalent yield 19.68 t ha^-1 was recorded from the treatment T3 (100 % maize + spinach). The same combinations also gave highest gross return (Tk. 373930 ha^-1) and gross margin (Tk. 258585 ha^-1) as well as benefit cost ratio (3.24). Though highest grain yield was recorded from sole maize but equivalent yield and economic return was much lower than the treatment T3.

Objectives:

This experiment was designed to study the feasibility and agro-economic performance of maize intercropping with different short duration vegetable crops.

Methodology:

The experiment was conducted at MLT site Bhuapur, Tangail during rabi season of two consecutive years of 2012-13 and 2013-14 under AEZ#8. The experiment was laid out in a Randomized Complete Block Design with six dispersed (six farmers’ field) replications. Five treatment combinations viz. T₁= Sole Maize, T₂= 100 % Maize (maize paired row) + Potato (var. Diamant), T₃= 100 % Maize (maize paired row) + Spinach (var. local), T₄= 100 % Maize (maize paired row) + Red amaranth (var. BARI Lalshak-1) and T₅= 100 % Maize (Maize paired row) + Radish (var. BARI Mula-1) were studied. The unit plot size was 8 m × 5 m. Three rows (45 cm x 20 cm) of potato, spinach (broadcast), red amaranth (broadcast) and four rows (30 cm x 10 cm) of radish were sown in between paired rows of maize (maize paired row spacing was 150 cm, line to line spacing 37.5 cm and plant to plant 25 cm). The spacing for sole and intercropping maize was 75 cm × 25 cm. Maize, potato, spinach, red amaranth and radish seeds were sown during 20-27 November, 2012 and 25-30 November, 2013. Fertilizers were applied @ 255-55-140-40-6-2 kg ha^-1 N-P-K-S-Zn-B for maize. 1/3 N and full amount of other fertilizers were applied as basal. Rest N was applied in maize rows as top dress in two equal splits at 30 and 60 days after sowing (DAS). Subsequently three irrigations were applied at 20, 30 and 60 DAS. Earthling up was done at 30 days after planting potato. Two hand weeding were done at 20 and 35 DAS to keep the crop weed free. The main crop (maize) was harvested from 23 April to 2 May, 2013 and 15-20 April, 2014. The intercropped vegetables such as potato, spinach, red amaranth and radish were harvested at 90-94, 31-42, 27-41 and 50-66 DAS, respectively in both cropping season. Yield component data of crops were collected prior to harvest from each plot. Data of two years were analyzed statistically and mean comparison was done by LSD test. The relative yield was obtained by dividing the intercrop yield of a crop with the respective sole crop yield of that crop using the formula (Dewit and Vander Bergh, 1965).

Maize equivalent yield was calculated by converting the yield of red amaranth, radish, spinach, potato into the yield of maize on the basis of prevailing market price using the formula of Anjaneyulu et al. (1982). Benefit cost analysis were also done.

Achievement/Findings:

From the results, it revealed that maize grown as intercrop with short duration vegetables like potato, spinach, red amaranth and radish may be profitable than sole maize. All of the intercrop combinations are agronomically and economically viable than sole cropping. But, he results suggested that the possibility of obtaining a reasonably good yield and profitable economic return from intercropping maize with spinach in char land area of Bhuapur, Tangail.
