Abstract/ Executive Summary:

The experiment was conducted at Agronomy Research Field, Bangladesh Agricultural Research Institute, Gazipur during 2010-11 to find out the appropriate planting system of potato and plant density of maize in potato- hybrid maize intercropping system for maximum yield and economic return. Ten treatments were evaluated viz., T₁= Potato whole tuber single row (75 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T₂=Potato whole tuber single row (75 cm × 20 cm) + 100% hybrid maize (75cm × 25 cm), T₃= Potato whole tuber single row (75 cm × 20 cm) + 83% hybrid maize (75 cm × 30 cm), T₄= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T₅= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) +100% hybrid maize (75 cm × 25 cm), T₆= Potato half tuber paired row (20 cm/ 55 cm× 20 cm) + 83% hybrid maize (75 cm × 30 cm), T₇= Sole potato whole tuber single row planting system (60 cm × 25 cm), T₈ = Sole potato half tuber paired row (20 cm/ 55 cm × 20 cm), T₉= Sole hybrid maize in normal spacing 75 cm × 25 cm (sole HM1) and T₁₀= Sole hybrid maize (75 cm × 25 cm) sown 30 days after potato planting (sole HM2). The results revealed that sole planting of both potato and maize produced the maximum yields. In case of sole potato, potato half tuber paired row planting system was better than potato whole tuber single row planting system. On the other hand, the performance of sole HM1 was better than sole HM2 in relation to growth, yield and economic performance. Over all T₁ treatment ( potato whole tuber single row planting system with 125% hybrid maize population) was the best intercropping system for getting higher yield and economic return as well as less relative crowding coefficient with better crop performance ratio.

Objectives:

To find out planting arrangement/system of potato and plant density/spacing of maize in potato maize intercropping system for getting higher yield and economic return.

Methodology:

The experiment was conducted at the Agronomy research field of BARI, Joydebpur during the rabi season of 2010-11. Ten treatments were evaluated in the experiment viz., T₁= Potato whole tuber single row (75 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T₂=Potato whole tuber single row (75 cm × 20 cm) + 100% hybrid maize (75cm × 25 cm), T₃= Potato whole tuber single row (75 cm × 20 cm) + 83% hybrid maize (75 cm × 30 cm), T₄= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T₅= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) +100% hybrid maize (75 cm × 25 cm), T₆= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) + 83% hybrid maize (75 cm × 30 cm), T₇= Sole potato whole tuber single row planting system (60 cm × 25 cm), T₈ = Sole potato half tuber paired row (20 cm/ 55 cm × 20 cm), T₉= Sole hybrid maize in normal spacing 75 cm × 25 cm (sole HM1) and T₁₀= Sole hybrid maize (75 cm × 25 cm) sown 30 days after potato planting (sole HM2). The experiment was laid out in randomized complete block design with three replications. The unit plot size was 6.0 m × 5.0 m. The potato var. BARI Alu 8 (Cardinal) and maize var. BARI Hybrid maize 7 were used in the experiment. Sole potato, intercropped potato and sole HM1 (T₉) were planted on 22 November, 2010. Sole HM2 (T₁₀) and intercropped maize were planted on 22 December, 2010. Fertilizers were applied @ N₁₈₀P₄₀K₁₈₀S₂₀Zn₆B_1.2 kg/ha and N₂₆₀P₇₂K₁₄₈S₄₈Zn₄B₂ kg/ha for sole potato and sole hybrid maize, respectively (FRG, 2005). For intercrop fertilizers were applied @ N₃₂₀P₇₃K₁₇₀S₅₀Zn₆B₂ kg/ha. The source of N, P, K, S, Zn and B was urea, triple super phosphate (TSP), muriate of potash (MoP), gypsum, zinc sulphate and boric acid, respectively. In case of sole potato, half amount of urea and MoP and the whole amount of TSP, gypsum, zinc sulphate and boric acid were applied at the time of final land preparation. Remaining half amount of urea and MoP were applied at 30 days after planting (DAP). For sole maize, one-third of urea and whole amount of other fertilizers were applied at the time of final land preparation. Remaining amount of urea was applied in two equal splits as side dressing at 30 and 55 days after sowing (DAS). In case of intercrop, 1/3 urea as basal, 1/3 at 30 DAP & 1/3 after potato harvest followed by irrigation and all other fertilizers were applied as basal. Irrigation and other intercultural operations were done as and when required. Fungicide (Dithane M 45) was sprayed at every 10-day intervals beginning from 25 DAP to 70 DAP for preventing potato disease. Photosynthetically active radiation (PAR) was measured by PAR Ceptometer (Model – LP-80, Accu PAR, Decagon, USA). PAR (µmole s^-1 m^-2) was measured at 10-day intervals from 30 to 90 day after emergence (DAE) of potato at around 11:30 am to 13:00 pm. Potato was harvested at 95 DAP on 24 February, 2011 and hybrid maize were harvested on 6 May, 2011 (135 DAS) except sole HM1 (T₉) which was harvested on 15 April, 2011 (144 DAS). Collected data of both the crops were analyzed statistically and the means were adjudged using DMRT at 5% level of probability. Economic analysis was also done considering local market price of harvested crops.

Achievement/Findings:

The result revealed that the intercropping system of potato whole tuber single row planting system (75cm × 20cm) + 125% hybrid maize (75cm × 20cm) was the most productive and profitable combination than all other intercropping systems as well as than sole cropping of potato and maize.
