A field experiment was carried out at the Regional Pulses Research Station of Bangladesh Agricultural Research Institute, Madaripur, Bangladesh during rabi season of 2013-14 and 2014-15 to select effective insecticides to control pod borer (Helicoverpa armigera Hubner) of chickpea (Cicer arietinum). Signinificantly the highest insect infestation and yield loss were recorded from untreated control. Spray with every insecticide for 3 times at 7 days interval reduced insect infestation and yield loss significantly over control in both years. Reduction in insect infestation was 11.77-18.77% and 6.34-13.34% and yield loss was 280-393-168-281 kgha-1 in 2013-14 and 2014-15, respectively. The highest grain yield was obtained with Tracer 45 SC (Spinosad) (1177 kgha-1) followed by Volium Flexi 300 SC (Thiamethaxam) (1045 kgha-1) and Belt 24 WG (Flubendiamide) (1020 kgha-1) in first year. In second year, Tracer 45 SC produced maximum yield (1396 kgha-1) followed by Volium Flexi 300 SC (1315 kgha-1) and Admire 200 SL (Imidacloprid) (1300 kgha-1). In 2013-14, the highest benefit cost ratio (3.39) was obtained with Volium Flexi 300 SC followed by Belt 24 WG (2.65) and Admire 200 SL (1.67). In 2014-15, the highest benefit cost ratio was also obtained with Voilum Flexi 300 SC (2.38) followed by Admire 200 SL (1.79) and Belt 24 WG (1.63). Comparing two years data considering highest profit, Volium Flexi 300 SC might be applied @ 0.05% at an interval of 7 days to the crop for three times.Bangladesh J. Agril.

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.

A study on comparative productive efficiency and feasibility of lentil varieties both at relay and minimum tillage were conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh during the Rabi season of 2007-08 and 2008-09. Three lentil varieties viz. BARI Masur-2, BARI Masur-3 and BARI Masur-4 and two sowing methods viz. relay sowing and furrow sowing (Minimum tillage) were compared. The highest seed yield (1.59 t/ha) was obtained from BARI Masur-4 because of highest number of pods/plant and plant population/m2 while lowest from BARI Masur-2 (1.39 t/ha). The sowing methods had significant effect on the seed yield of lentil. Crops sown in furrows produced higher seed yield (1.60 t/ha) than that of crops in relay sowing. The interaction effect between varieties and sowing methods also had significant effect on the seed yield and yield attributes. The lentil variety BARI Masur-4 when grown in furrows gave the highest seed yield (1.70 t/ha). Though seed yield and gross return were highest in furrow sowing but highest benefit cost ratio (4.67) was found in relay sowing method.Bangladesh J. Agril. Res. 40(2): 271-278 June 2015

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.

An experiment was conducted with the objective of ascertaining the feasibility of cultivation of pigeonpea during rabi season in the alfisols of Southern Telangana Zone. Further, it was designed to understand the performance of pigeonpea genotypes at various plant densities and also the economics of pigeonpea cultivation during rabi season. It consisted of 12 treatments with four plant densities in main plots and three genotypes in sub plots in split plot design. The pooled data of 2015-16 and 2016-17 revealed that significantly higher seed yield (1532 kg ha-1) was recorded at plant density of 60 cm × 10 cm spacing than at 45cm × 10cm (1332 kg/ha), 75 cm × 10 cm (1321 kg/ha) and 90 cm × 10 cm (1141 kg/ha). Among the genotypes, the seed yield in PRG-158 (1547 kg/ha) and Asha (ICPL 87119) (1591 kg/ha) was on par with each other but significantly higher than in PRG-176 (857 kg/ha). The higher gross returns (Rs. 77366 ha-1), net returns (Rs.46733 ha-1) and benefit cost ratio (2.53) was recorded at plant density of 60 cm × 10 cm spacing than at other tested plant densities (45 cm × 10 cm, 75 cm × 10 cm and 90 cm × 10 cm). Among the genotypes, Asha (ICPL 87119) registered highest gross returns (Rs. 80346 ha-1), net returns (Rs.49711 ha-1) and benefit cost ratio (2.62) followed by PRG-158 (gross returns of Rs. 78124ha-1, net returns of Rs.47489 ha-1 and benefit cost ratio of 2.55) and PRG-176 (gross returns of Rs. 43279ha-1, net returns of Rs.13144 ha-1 and benefit cost ratio of 1.44). Thus, the spacing of 60 cm × 10 cm is recommended for the cultivation of pigeonpea during rabi season in alfisols of Southern Telangana Zone with long duration varieties like PRG-158 and Asha (ICPL-87119).

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.

An experiment was carried out during thekharif season of two consecutive years 2014 and 2015 at Regional Research Sub-station, Raghunathpur, Bidhan Chandra Krishi Viswavidyalaya, Purulia, West Bengal with the view to maximise the jute seed yield by manipulating certain non-monetary techniques like dates of sowing and topping associated with crop production. The Capsularis variety Bidhan pat-3 was sown in three different dates (1st-25th June, 2nd-15th July and 3rd-5th August) with 3 topping (clipping of apical portion) practices at 30, 45 and 60 days after sowing (DAS) as separate treatment with no topping as control. These different agronomic practices significantly (at 5 % probability level) influenced the performance of the crop in various aspects. The 1st date of sowing showed its supremacy in terms of expression of the crop in the field in all the aspects achieving a seed yield of 709.50 kg ha-1 and 737.85 kg ha-1 during first and second year respectively, whereas, the last date of sowing showed its inferiority obtaining a seed yield of 590.10 kg ha-1 and 647.13 kg ha-1all through the first and second year respectively.1stdate of sowing also recorded higher net return(Rs. 33721.50 ha-1& Rs.35989.50 ha-1 during first and second year) and benefit: cost ratio (1.46 and 1.56 in first and second year) over the other two date of sowing. How-ever, maximum seed yield was achieved when the crop was topped on 45 DAS (728.80 kg ha-1 and 773.57 kg ha-1 during first and second year) irrespective of the date of sowing.
