Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

The aim of this study is to find out effects of different trellis-vegetables grown at the edge of the rice field on the productivity and profitability of transplanted modern aman rice BINA Dhan-7. The study design was held as a Randomized Complete Block Design (RCBD) since it was repeated three times. The experimental treatments were T1 = rice + bottle gourd, T2 = rice + white gourd, T3 = rice + yard long bean, T4 = rice + bitter gourd and T5 = rice + cucumber. The results revealed that grain yield was the highest (3.48 t ha-1) in rice + cucumber (T5) and the lowest grain yield (2.65 t ha-1) was found in rice + bottle gourd (T1). In terms of vegetable production, the maximum vegetable yield (21.33 t ha-1) was obtained from rice + bottle gourd (T1) and the minimum value (0.25 t ha-1) was received from rice + cucumber (T5) crop combination. Moreover, the highest rice equivalent yield (23.98 t ha-1) was found from rice + bottle gourd (T1) crop combination and lowest value (3.48 t ha-1) was found from rice + cucumber (T5) crop combination. The highest value of gross return (Tk. 316290 ha-1) was obtained from the T1 treatment (rice + bottle gourd) and the lowest value of gross return (Tk. 50835 ha-1) was recorded from the treatment T5. The maximum benefit-cost ratio (3.35) was recorded from T1 treatment and the lowest benefit-cost ratio (0.71) was observed in T5 treatment. Finally, the growing of bottle gourd production at the edge of transplanted aman rice BINA Dhan-7 cultivation approach will be a significantly beneficial production technique.

Burirhat, Rangpur during two consecutive seasons of 2004-05 and 2005-06, respectively, to find out suitable row arrangement of carrot with groundnut for higher yield and economic return. There were six treatments, such as sole groundnut, sole carrot, one row of carrot in between two normal rows of  groundnut, two rows of carrot in between two normal rows of groundnut, two  rows of groundnut alternated with two rows of carrot and three rows of  groundnut alternated with three rows of carrot. Results showed that monoculture  produced the highest yields of individual crops but in intercropping system the  highest groundnut equivalent yield (10.63 t/h and 11.10 t/ha) was obtained from two rows of carrot in between two rows of groundnut. The maximum land  equivalent ratio (1.67 and 1.74), the highest gross return (Tk.212600/ha and  Tk. 248400/ha) and net return (Tk.184881/ha and Tk.211680) were also obtained from the intercropping treatment with two rows carrot in between two normal rows of groundnut. But due to higher cost in this treatment, maximum benefit cost ratio (7.09 and 7.01) was obtained from the intercropping treatment    with one row carrot in between two normal rows of groundnut in both the years.

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.
