The experiment was conducted at Agronomy field of Bangladesh Agricultural Research Institute, Gazipur during 2016-2017 and 2017-2018 to determine the nutrient requirement for yield maximization of Bt brinjal (var. BARI Bt Begun-2). The treatments were T1= STB (soil test base) recommendation (120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B+ 3 t/ha poultry manure), T2 = T1 + 25% of N-P-K-S-Zn-B (150-45-112-18-2.5-1.25 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure), T3= T1 + 50% of N-P-K-S-Zn-B (180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure), T4= T1 + 25% of N-P-K-S-Zn-B + 3 t/ha poultry manure (150-45-112-18-2.5-1.25 kg/ha N-P-K-S-Zn-B+6 t/ha poultry manure), T5= T1 + 3 t/ha poultry manure (120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B + 6 t/ha poultry manure). Nutrient uptake, yield components and yield of Bt brinjal varied significantly due to variation of nutrients in the tested years. The highest plant height (98-116 cm), canopy coverage (1.21-1.26 m2/plant), number of fruits/plant (57.69-59.23) and individual fruit weight (83-86 g) were obtained from 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure (T3) treatment where days to flowering showed the lowest values (109-110 days). The highest pooled yield (58.46 t/ha) of Bt brinjal was observed from the treatment 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure(T3) and the lowest (23.39 t/ha) from 120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B+ 3 t/ha poultry manure) (T1). The highest nutrient uptake (214-43-208-60-0.38-0.213-49 kg/ha N-P-K-S-B-Ca) was also observed from the same treatment (T3). Fruit yield showed a strong (r=0.97) linear relationship with applied nutrients. Effect of nutrient application on fruit yield of Bt brinjal was estimated about 86%. The highest gross return (Tk. 587900/ha), gross margin (Tk. 417660/ha) and benefit cost ratio (3.45) were obtained by applying 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B+3 t/ha poultry manure. Results revealed that application of 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B along with 3 t/ha poultry manure would be economically optimum for achieving higher yield of Bt brinjal grown under Grey Terrace soil (Aeric Albaquept) of Gazipur.

A field experiment on intercropping of okra and leafy vegetables was conducted at Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur and Agricultural Research Station, Burirhat, Rangpur during Kharif-I season of 2010 and 2011 to find out suitable crop combination for higher productivity and economic return. Seven treatments viz., sole okra (50 cm × 40cm), okra 100% (in row) + red-amaranth 100% (broadcast), okra 100% (in row) + red-amaranth 75% (broadcast), okra 100% (in row) + leaf amaranth 100% (broadcast), okra 100% (in row) + leaf amaranth 75% (broadcast), okra 100% (in row) + jute as patshak 100% (broadcast), okra 100% (in row) + jute as patshak 75% (broadcast) were used. Intercropping reduced okra yield but total productivity increased due to additional yield of vegetables. In both the locations, sole okra produced the highest yields (15.82 t/ha at Joydebpur and 13.79 t/ha at Burirhat). Among the intercropping treatments, the highest okra yields (15.42 t/ha at Joydebpur and 12.64 t/ha at Burirhat) were obtained from okra 100%+ red amaranth 75% combination. The lowest okra yield (13.16 t/ha at Joydebpur and 11.75 t/ha at Burirhat) was recorded in okra 100% + jute as patshak 100% combination. The highest okra equivalent yield (23.00 t/ha) was recorded in okra 100% + red amaranth 100% at Joydebpur and in okra 100% + leaf amaranth 100% (21.79 t/ha) at Burirhat. These treatment combinations also gave the highest gross margin (Tk. 227180/ha at Joydebpur and Tk. 214600/ha at Burirhat) and benefit cost ratio (5.66 at Joydebpur and 5.58 at Burirhat). The results revealed that cent percent red amaranth (broadcast) or leaf amaranth intercropped with cent percent okra might be suitable combination for higher productivity and economic return at Joydebpur and Burirhat, respectively.

The experiment was conducted to find out a suitable intercrop combination of Bilatidhonia and winter pumpkin relayed with different summer cucurbits (Bilatidhonia + winter pumpkin)/summer cucurbits) in the hill valley of the Agricultural Research Station (ARS), Raikhali, Rangamati during 2003-04 and 2004-05. The results revealed that all the intercrop combinations gave the highest fresh yield of Bilatidhonia than that of the sole Bilatidhonia with an exception of Bilatidhonia + winter pumpkin followed by ash gourd and summer pumpkin combination. Maximum fresh yield of Bilatidhonia (50.13 t/ha) was recorded from Bilatidhonia + winter pumpkin closely followed by ribbed gourd and bitter gourd (50.00 t/ha) combination which showed 15-15.5% higher than that of sole Bilatidhona. Summer cucurbits relayed with Bilatidhonia after harvesting of winter pumpkin gave reasonable good yield where ribbed gourd produced the highest yield (15.29 t/ha). Winter pumpkin intercropped with Bilatidhonia also produced reasonable good yield ranging from 31.88 to 32.68 t/ha compared to the sole winter pumpkin. The highest Bilatidhonia equivalent (69.02 t/ha) and gross return (Tk. 10,35,35,440/ha) were obtained from (Bilatidhonia + winter pumpkin)/ bitter gourd or ribbed gourd combination. But intercropped Bilatidhonia with winter pumpkin relayed by ribbed gourd gave the highest gross margin (Tk. 859, 566/ha) with maximum benefit-cost ratio (4.90) at hilly area of Raikhali, Rangamati.DOI: http://dx.doi.org/10.3329/bjar.v32i3.536Bangladesh J.

A field experiment was conducted at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Ishurdi, Pabna during two consecutive years of 2012-2013 and 2013-2014 to find out the suitable combination of intercropping of chili with sweet gourd for increasing the productivity and economic return. The treatments were T1=100% sweet gourd (2m x 2m) + 40% chili (50cm x 100cm) + 100% recommended fertilizer (RF) of chili, T2=100% sweet gourd (2m x 2m) + 40% chili (50cm x 100cm) + 75% RF of chili, T3=100% sweet gourd (2m x 2m) + 40% chili (50cm x 100cm) + 50% RF of chili, T4=100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 100% RF of chili, T5=100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 75% RF of chili, T6=100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 50% RF of chili, T7=Sole sweet gourd, T8= Sole chili. The experiment was laid out in a randomized complete block design with three replications. Fruit yield was calculated for sweet gourd and chili in ton per hectare considering the whole plot as harvested area. Results revealed that the yield of both sweet gourd and chili significantly affected by plant population and fertilizer dose in the intercropping systems. The highest equivalent yield of sweet gourd (21.21 t ha-1), land equivalent ratio (1.59), gross return (Tk. 318150.00 ha-1), gross margin (Tk. 237935.00 ha-1) and benefit cost ratio (3.97) were obtained from 100% sweet gourd (2m x 2m) + 50% chili (50cm x 80cm) + 100% RF of chili (T4). Sole crop of chili (T8) gave the lowest equivalent yield of sweet gourd (7.38 t ha-1), gross return (Tk. 110700.00 ha-1), gross margin (Tk. 37455.00 ha-1) and benefit cost ratio (1.51). Therefore, sweet gourd (100%) and chili (50%) with recommended fertilizer (100%) of chili might be economically profitable for chili with sweet gourd intercropping system.Int. J. Agril. Res.

An intercropping experiment was conducted on hill valley at Hill Agricultural Research Station, Ramgarh and Kharachari during two consecutive rabi seasons of 2012-13 and 2013-14 to select suitable local bush bean cultivar for intercropping with hybrid maize in hilly areas of Bangladesh. Seven intercropping treatments viz., T1 = Normal maize spacing (75 cm × 25 cm) + 2 rows black seeded bush bean,T2 = Normal maize spacing (75 cm × 25 cm) + 2 rows pink seeded bush bean,T3 = Maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows black seeded bush bean,T4 = Maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows pink seeded bush bean, T5 = Maize wider spacing (100 cm × 50 cm) with 2 plants/hill + 3 rows black seeded bush bean, T6 = Maize wider spacing (100 cm × 50 cm) with 2 plants/hill + 3 rows pink seeded bush bean and T7 = Sole maize spacing (75 cm × 25 cm) were used. Sole hybrid maize produced the highest grain yield at both the locations. Bush bean cultivars in intercropped situation depressed hybrid maize yields by 7.15-37.29% at Ramgarh and 2.56-37.51% at Khagrachari compared to sole hybrid maize. The highest maize equivalent yield of 23.10 t/ha at Ramgarh and 24.08 t/ha at Khagrachari was recorded in maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows pink seeded bush bean combination (T4). The same treatment also showed the highest gross return (Tk 277200/ha at Ramgarh and Tk 288960/ha at Khagrachari), gross margin (Tk 180050/ha at Ramgarh and Tk 191810/ha at Khagrachari) and benefit cost ratio (2.85 at Ramgarh and 2.97 at Khagrachari). The result revealed that maize wider spacing (100 cm × 25 cm) with 1 plant/hill + 3 rows pink seeded bush bean could be suitable and economically profitable for hybrid maize and bush bean intercropping in hill valleys of Bangladesh.Bangladesh J.

The experiment was conducted at Multiplication Testing Site (MLT) Trishal of on-farm research division, Bangladesh Agricultural Research Institute, Mymensingh during 2015-16 and 2016-17 to study the comparative agro-economic performance of four crops pattern for increasing cropping intensity and productivity as compared with existing farmers’ pattern. Four crops pattern (Boro-T.Aus-T.Aman-Mustard) and farmers’ existing pattern (Boro-fallow-T.Aman- fallow) as control were tested. On an average, organic matter 3.94 t ha-1and 2.60 t ha-1 were added to soil in four crops pattern and farmers existing pattern by incorporation of biomass of respective crops.. Two years average results showed that the highest rice equivalent yield (20.63 t ha-1) was obtained from four crops pattern. The highest average gross return and gross margin of the four crops pattern were obtained Tk.359570 and Tk. 170162 ha-1 which were 80 and 207 % higher over farmers’ pattern. Farmers’ practice gave the lower gross return (Tk. 199790 ha-1). The mean marginal benefit cost ratio (MBCR) was found 2.23 which indicated the superiority of four crops pattern over the farmers’ existing pattern. The marginal benefit cost ratio (MBCR) analysis also showed that inclusion of mustard and T.Aus rice in the existing pattern might be profitable and acceptable to the farmers. Nutrient uptake and balance showed that considerable amounts of N, P, K and S were removed by crops every year. However, the N, K and S balances were found negative in all cases but P balance was found positive. From the above result showed that four crops can be grown successfully one after another in sequence of the tested pattern.SAARC J. Agri., 15(2): 103-112 (2017)

A field experiment was conducted at the Regional Agricultural Research Station, Ishurdi, Pabna, Bangladesh during 2008-09 and 2009-2010 to find out the suitable intercrop combination of sesame with mukhikachu for getting higher productivity and economic return. Five treatments comprised of T1 = sole mukhikachu (double row:20 cm/55 cm/20 cm × 45 cm), T2=sole sesame (30 cm×5 cm), T3 = mukhikachu (double row:20 cm/55 cm/20 cm × 45 cm) + one row sesame (30%), T4 = mukhikachu (double row:20 cm/55 cm/20 cm × 45 cm) + two row sesame (60%), and T5 = mukhikachu (double row:20 cm/55 cm/20 cm × 45 cm) + sesame broadcast (100%). The results showed that intercropping systems affected the cormel yield of mukhikachu and seed yield of sesame. Mukhikachu yield decreased with the increase of sesame population in intercropped combination. The highest mean mukhikachu equivalent yield (15.65 t/ha), land equivalent ratio (1.83), gross return (Tk.187585/ha), gross margin (Tk. 114265/ha), and benefit cost ratio (2.56) were obtained from two rows of sesame (30 cm × 5 cm) in between two double rows (20 cm/55 cm/20 cm × 45 cm) of mukhikachu. Sole crop of sesame gave the lowest mukhikachu equivalent yield (4.02 t/ha), gross return (Tk.48125/ha), gross margin (Tk. 19655/ha), and benefit cost ratio (1.69). Two years' study revealed that two rows of sesame (60%) in between two double rows (20 cm/55 cm/20 cm × 45 cm) of mukhikachu was found profitable intercropping combination.

An intercropping experiment was conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna during 2007-2008 and 2008-2009 to find out the suitable intercrop combination for increasing total productivity and returns. Seven treatments, viz. sole pointed gourd, two times lalshak + two rows turmeric in between pointed gourd lines, two times spinach + two rows turmeric in between pointed gourd lines, one time bushbean + two rows turmeric in between pointed gourd lines, two times lalshak + two rows ginger in between pointed gourd lines, two times spinach + two rows ginger in between pointed gourd lines and one time bushbean + two rows ginger in between pointed gourd lines were compared. All the intercropping combinations were higher in terms of pointed gourd equivalent yield, gross return, gross margin and benefit cost ratio (BCR) over sole crops. The highest pointed gourd equivalent yield (105.92 t ha-1) and gross return (Tk. 2118480 ha-1) was found from two times spinach + two rows ginger in between pointed gourd lines combination. The land equivalent ratio was observed highest (2.29) in same combination which was similar to one time bushbean + two rows ginger in between pointed gourd lines combination. One time bushbean + two rows ginger in between pointed gourd lines combination gave the highest monetary returns in respect of gross margin (Tk.1623333 ha-1) and BCR (4.19). The increases in total productivity in terms of pointed gourd equivalent yields were 53.72-128.62 t ha-1 in intercrop combination compared to base crop.Bangladesh Agron. J. 2015, 18(1): 7-12
