Abstract/ Executive Summary:

A study was conducted during April 1987 to March, 1989 to find out suitable crop or crop combinations for Kharif season and subsequent effect on cotton. Two years results showed that the highest maize and rice grain yield was obtained from their respective sole crops. The highest rice equivalent yield (3.42 t/ha), net return (Tk. 8500/ha) and benefit: cost ratio (2.0 I: 1.00) were obtained from an intercrop system of maize paired row + blackgram in Kharif season. The highest total net return (Tk. 47,267/ha) was obtained from the maize paired row + rice-cotton cropping pattern which was followed by the maize paired row + blackgram-cotton (Tk. 45,000/ha) cropping pattern.

Keywords: Cotton based cropping pattern, Rice equivalent yield, Net return, Rice

Location: Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Jessore

Start Date: 00-04-1987

End Date: 00-03-1989

Program Area: Farming System

Commodity: Cotton

Objectives:

To develop a profitable and suitable cropping pattern with cotton as a component crop to popularize cotton cultivation.

Methodology:

The experiment was conducted at Regional Agricultural Research Station (RARS). Bangladesh Agricultural Research Institute, Jessore, Bangladesh during the two consequtive years from April, 1987 to March, 1989. The soil was a silty loam, pH 7.1 and belongs to the calcareous brown flood- plain soil of Darsana series. The crops were grown under rainfed condition. The experiment consisted of the following 10 treatments for Kharif-I cropping and each treatment was followed by cotton. T_I = Broadcast "Aus' rice (var. Hashikalmi @ 100 Kg. seeds/ha) , T₂ = Row seeded 'Aus' rice (@ 50 Kg seeds/ha with 30 cm apart,), T₃ = Broadcast blackgram (var. MAK-I in I 987-88)/mungbean (MK-73 in 1988-89 @ 24 kg seeds/ha), T₄ = Sole maize (var. Barnali with 75cm x 25cm spacing), T₅ = Maize paired row (37.5 cm spacing within a pair and 150cm between pairs), T₆ = Maize paired row as above + rice (5 rows at 30cm apart), T₇ = Maize paired row as above + blackgram/mungbean (5 rows at 25cm apart), T₈ = Rice (3 rows of 30cm apart) + Blackgram/mungbean (4 rows of Zflcrn apart), T₉ =Rice broadcast in strip + Sesbania broadcast in strip (var. Local @ 20 kg seeds/ha) and T₁₀ = Row seeded Aus rice (100%) + Sesbania broadcast in strip (50%). The experimental design was randomized complete block with four replications having a plot size of 5 111 x 3111. Sale' Aus' rice and intercropped 'Aus' rice were fertilized with 60-40-40 kg/ha of N, P₂0₅ and K₂0. Sale and intercropped maize received 120-60-40 kg/ha of N, P₂0₅ and K₂0. Sole blackgrarn/mungbean received 20-40-20 kg/ha of N, P₂0₅ and K₂0 kg/ha. The crops were planted on 21 Ist April and 27th April in 1987 and 1988 respectively. Two weedings were done for 'Aus ' rice once in the third week and the other in the fifth week after sowing. Two weeding cum earthing up were carried out for maize in the third and fifth weeks. Sesbania was chopped into small pieces and mixed with soil in the 6th week after sowing. Blackgram/rnungbean was harvested by two pickings in the month of June and plant parts were incorporated in the soil. Rice was harvested in 9th August, 1987 and 19th august, 1988 respectively. After harvesting Kharif-I crops. cotton was seeded on 21 Ist August in 1987 and 25th August in 1988 using variety BAC-7 (Rupali) at 60cm x 30cm spacing. The crop was fertilized at the rate of 90-50-60 kg/ha of N, P₂0₅ and K₂0 respectively. Full dose of P₂0₅, K₂0 and 30 kg N/ha was applied at the time of final land preparation and the rest 60 kg N/ha was applied in two installments in 4th and 8th week after crop emergence. Two manual weedings were done in 3rd and 6th week after crop emergence. Insecticides Azodrine and Ripcord were sprayed three times during vegetative and reproductive stages to control insects. Harvesting was done by three pickings in the months of February through March. Yield and yield components were collected and statistically analysed (Steel and Torrie, 1960). Total man hours required for different operations along with cost for different treatments were recorded. Benefit: cost analysis was done for each treatment on a hectare basis taking into account market values of different crops. Rainfall data were collected from Meteorology section of RARS, Jessore.

Achievement/Findings:

The highest rice equivalent yield (3.42 t/ha), net return (Tk. 8500/ha) and benefit: cost ratio (2.0 I: 1.00) were obtained from an intercrop system of maize paired row + blackgram in Kharif season. The highest total net return (Tk. 47,267/ha) was obtained from the maize paired row + rice-cotton cropping pattern which was followed by the maize paired row + blackgram-cotton (Tk. 45,000/ha) cropping pattern.
