Five IPM packages viz. T1=Pheromone trap @ 70 traps ha-1 + Neem seed kernel extract @ 50 g L-1 of water; T2=Pheromone trap + HaNPV @ 0.4 ml L-1 of water and Bt @ 2.0 g L-1 of water; T3=Pheromone trap + Neem seed kernel extract + HaNPV and Bt; T4=Pheromone trap + Trichogramma chillnis @ 50,000 ha-1 and Bracon hebetor @ 1200 ha-1; T5=Pheromone trap + Neem seed kernel extract + T. chilonis and B. hebetor were evaluated against H. armigera in tomato. The lowest fruit infestation by number (12.55%) was attained from T5 followed by T2 (15.49%). Significantly the lowest fruit infestation by weight was found in treatment T2 (10.60%) followed by T5 (11.73%). The highest yield was obtained from T5 (29.74 t ha-1) followed by T2 (26.77 t ha-1). The highest marginal benefit cost ratio was achieved from T2 (3.41) followed by T5 (3.35). Hence, considering benefit cost ratio, T2 and T5 packages may be the effective tools for managing H. armigera in tomato.Bangladesh J. Agril. Res. 41(2): 287-296, June 2016

To develop a suitable integrated pest management (IPM) package(s) against tube spittle bug attacking jujube, the study was conducted at the farmer’s orchard at Sherpur Upazilla of Bogra district, Bangladesh during the two consecutive winter seasons of 2011-12 and 2012-13. There were five IPM packages viz., P1 = Clean cultivation + collection and destruction of tube with alive nymph from the branches, P2 =P1 + two sprays of Detergent @ 2gl-1 of water applied (at initial stage of infestation and 10 days after 1st spray), P3 =P1 + two sprays of crushed Neem seed extract @ 150 gl-1 of water (at initial stage of infestation and 10 days after 1st spray), P4 =P1 + sprays of Cypermethrin @ 1 mll-1 of water at initial stage of infestation, P5 =P4 + one additional spray of Cypermethrin @ 1mll-1 at 10 days after 1st spray and an untreated control. In both the years, treatment P5 was found most effective, which resulted lower damage to inflorescence and produced higher yield, followed by P4 and P3.  In case of marginal benefit cost ratio, the highest value (15.69 & 20.63) was obtained from the treatment P5 which was closely followed by P4 (15.07 &20.12) in both of years, respectively.The Agriculturists 2016; 14(1) 54-62

The experiment was conducted at Sher-e-Bangla Agricultural University farm, Dhaka, Bangladesh during the period from March to June 2007 with seven treatments viz; T1: Hand picking of infested fruits of bitter gourd at 7 days interval; T2: Neem seed kernel at 5 gm/l of water at 5 days interval +T1; T3: Spray of shobicron 425EC @ 2ml/l of water at 7 days interval + T1; T4: Micronutrient-Zn @ 6.72kg/ha; T5: Micronutrient-B @ 1.96kg/ha; T6: Micronutrient Zn + B and T7: Untreated control. The lowest fruit infestation (13.78%) by weight was recorded from the treatment T2, while the highest (46.09%) fruit infestation by weight was recorded from T7 untreated control. The highest (85.00) number of fruits per plot was recorded for T2 treated plots while the lowest (61.00) number of fruits per plot was recorded from the untreated control T7. The application of neem seed kernel at 5 days interval + hand picking of infested fruits in T2 treated plots gave the highest yield (12.88 t/ha) while it was lowest (10.02 t/ha) in T7 untreated control plots. The combined application of micronutrients was more effective in T6 than the single application of micronutrients in T4 and T5 respectively. The results of economic analysis of bitter gourd showed that the highest benefit cost ratio (9.44) was estimated for T6 treatment and the lowest (1.06) benefit cost ration for T3 treatment. Among the different treatments neem seed kernel at 5 days interval + hand picking of infested fruits in T2 treated plots was more effective than the insecticide Shobicron 425 EC at 7 days interval + hand picking of infested fruits followed by the T6 treated plots in combination of micronutrients Zn +B.

A field trial on soil test based (STB) fertilizer doses was conducted during the year of 2017-2018 and 2018-2019 in Jashore region (AEZ-11) to find out the most suitable fertilizer doses for four crop based cropping pattern considering the agronomic feasibility and economic return of the system. The experiment consisted of eight different treatments viz. T1: 100% NPKSZnB (STB), T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5:T1 + 25% PK, T6:T1 + 25% NPK, T7: 75% of T1, T8: Native fertility. Randomized complete block design (RCBD) with three replications was followed. Data revealed that seed yield of mustard was remarkably influenced by fertilizer treatments while grain yield of other components of the cropping system was not affected significantly by the treatments except control or native fertility. It was observed that 25% more NPK over 100% STB dose provided the highest yield of all the component crops. The highest rice equivalent yield (3.34 t ha-1) was recorded from T6 and the lowest (1.88 t ha-1) from T8 treatment. Maximum gross return (Tk. 420000/ha) and marginal benefit cost ratio (4.08) were also obtained from T6 treatment. So, 25% NPK+ 100% STB dose of fertilizer could be followed for productive and remunerative rice based cropping system Mustard-Boro-T. Aus-T.Aman in AEZ-11. Bangladesh Agron. J. 2021, 24(1): 109-117

The experiment was conducted to find out effective control measure against thrips and pod borers of mungbean by various means, including chemicals, botanicals and biopesticide. The mungbean variety, BARI Mung-6 was grown in the field and six treatments viz., T1 [Azadirachtin (Bioneem plus 1EC)], T2 [Bacillus thuringiensis (Bt. powder)], T3 [Spinosad (Tracer 45SC)], T4 [Chlorpyrifos + Cypermethrin (Nitro 505EC)], T5 [Thiamethoxam + Chlorantraniliprole (Voliam flexi 300SC)] and T0 [Untreated control (water spray)] were set in randomized complete block design (RCBD) with three replications. The insecticidal treatment options showed significantly different performance against thrips (Megalurothrips distalis), gram pod borer (Helicoverpa armigera) and legume pod borer (Maruca vitrata) on mungbean. The lowest population of thrips, gram pod borer and legume pod borer was found in Voliam flexi 300SC treated plot which showed maximum percent reduction of these pests. The lowest percent pod infestation by pod borers observed by the same treatment. Bioneem plus showed the intermediate results considering all the parameters. The maximum yield (1254.50 kg ha-1) and the highest marginal benefit cost ratio (MBCR) (6.68) were obtained from Voliam flexi 300SC. Considering effectiveness and marginal benefit cost ratio, Voliam flexi 300SC was more effective among treatments for controlling thrips and pod borers of mungbean followed by Nitro 505EC. SAARC J.

Farmer Income

<p>Rubber farmer income is not stable because the latex price is still fluctuative and tend to be low. The application of rubber-crop intercropping is one the strategies in increasing of land productivity and rubber farmer income. Farmers generally plant rubber with a standard single-row spacing of rubber (SR) 6-7 m x 3 m (475- 550 trees/ha), so the row-spacing area could be planted with crops up to 2 years. Furthermore, rubber canopy closure which cover surface of land could intensively reduce 55% of light intensity and 60% of crop yield. This paper explains about constraints and opportunities of development of rubber-crop intercropping technology to increase rubber farmer income and food production sustainability. One aspect that are concerned about is changing the standard single-row spacing (SR) to double-row spacing (DR). This aspect could be useful to enlarge the rubber spacing area land and thus the crops as intercropping could be properly planted. Crops are easier to get sunlight, temperature, and water if the crops are planted in DR system. However, population of rubber plant is slightly reduced and thus latex yield is also relatively declined comparing with SR system. Nevertheless, the DR system as rubber-crop intercropping has a good opportunity to develop for long term period, because light penetration area of 3-4 m from the row of rubber plant is still more than 80% on 8-9 years old of rubber plant. The development of rubber-crop intercropping technology could protect rubber farmers from fluctuation of rubber price and also enhance additional value. The analysis shows DR with upland rice, corn, and soybean is feasible to be developed with 1.98 of a marginal benefit cost ratio (MBCR).</p><p>Keywords: Rubber, rubber spacing, intercropping, food-crops</p><p> </p><p><strong>Abstrak</strong></p><p>Pendapatan petani karet belum stabil karena harga lateks berfluktuasi dan cenderung rendah. Penerapan tumpangsari karet - tanaman pangan merupakan salah satu strategi dalam meeningkatkan produktivitas lahan dan pendapatan petani karet. Petani umumnya menanam karet dengan sistem jarak tanam tunggal (JT) 6 - 7 m x 3 m (476 - 550 pohon/ha) sehingga lahan di antara tanaman karet hanya dapat ditanami tanaman pangan sampai tanaman pokok berumur 2 tahun. Selanjutnya tajuk tanaman karet sudah menutup permukaan lahan sehingga mengurangi intensitas cahaya sekitar 55% dan menurunkan hasil tanaman pangan sampai 60%. Tulisan ini membahas kendala dan peluang pengembangan teknologi tumpangsari karet - tanaman pangan dalam upaya peningkatan pendapatan petani dan produksi pangan secara berkelanjutan. Aspek yang menjadi perhatian dalam hal ini adalah mengubah sistem jarak tanam tunggal (JT) menjadi jarak tanam ganda (JG) agar ruang terbuka di antara tanaman karet lebih lebar untuk ditanami tanaman pangan sebagai tanaman sela. Pada areal di antara tanaman karet sistem JG, tanaman pangan lebih mudah mendapatkan sinar matahari, suhu, dan air, namun populasi tanaman karet sedikit berkurang, sehingga hasil lateks juga relatif berkurang dibanding tanaman karet sistem JT. Meski demikian, areal pertanaman karet sistem JG lebih berpeluang bagi pengembangan tumpangsari karet - tanaman pangan dalam jangka panjang, karena sampai tanaman karet berumur 8-9 tahun, penetrasi cahaya pada areal jarak 3-4 m dari barisan tanaman karet masih lebih dari 80%. Pengembangan teknologi tumpangsari karet - tanaman pangan dapat melindungi petani dari fluktuasi harga karet dan memberikan nilai tambah. Hasil analisis menunjukkan tumpangsari karet sistem JG dengan padi gogo, jagung, dan kedelai layak dikembangkan dengan marginal benefit cost ratio (MBCR) 1,98.</p><p>Kata kunci: Karet, jarak tanam karet, tumpangsari, tanaman pangan</p>

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Boro season of 2008 with a view to examining the effect of soil and foliar application of urea on the yield and nutrient uptake of BRRIdhan 29 and to evaluate whether urea foliar application (FA) could replace its soil application (SA) in the rice cultivation. The experiment was laid out in a randomized complete block design (RCBD) with eight treatments, each treatment replicated thrice. The treatments were: T1 (control), T2 (282 kg urea ha-1 SA), T3 (1% urea solution FA), T4 (2% urea solution FA), T5 (3% urea solution FA), T6 (94 kg urea ha-1 SA + 1% urea solution FA), T7 (94 kg urea ha-1 SA + 2% urea solution FA) and T8 (94 kg urea ha-1 SA + 3% urea solution FA). The results showed that soil and foliar application of nitrogen significantly influenced the growth and yield of crop. The treatment T2 (282 kg urea ha-1) produced the highest grain yield (5.34 t ha-1). The T6 (94 kg urea ha-1 + 1% urea solution FA) produced the highest straw yield (6.58 t ha-1) of the crop. The lowest grain yield (3.20 t ha-1) and the lowest straw yield (4.19 t ha-1) were recorded with T1 (control). Economic analysis showed that treatment T2 gave the highest marginal benefit cost ratio (7.65) while the lowest value (2.71) was observed with T5 treatment. The overall results demonstrated that soil application of 282 kg urea ha-1 was the best treatment for obtaining higher grain yield, higher nitrogen content of rice and higher marginal benefit cost ratio, and soil application is better than foliar application of urea.

The study was carried out during rabi season of 2015-16, 2016-17 and 2017-18 in 6 villages across 3 blocks (Rajsamand, Railmagra and Amet) of Rajsamand district. In all 225 front line demonstrations on chickpea crop were carried out in an area of 90.0 ha with the active participation of farmers with the objective to demonstrate the latest technology of chickpea production potential, technological gap, extension gap, technology index and economic benefit of improved technologies consisting suitable varieties GNG 1581, integrated nutrient management (20:40:0 NPK kg/ha + Rhizobium + PSB @ 20 g/kg seed) and integrated pest management (deep ploughing + seed treatment with Trichoderma viridae @ 6 g/kg seed +pheromone trap @ 10/ha + spray of Quinalphos @ 1.2 l/ha with 600 litres of water) at Rajsamand, Railmagra and Amet blocks of Rajsamand district during 2015-16 to 2017-18. The results revealed that FLD recorded higher yield as compared to farmers’ practices over the years of study. The improved technologies recorded average yield of 18.94 q ha-1 which was 27.97 per cent higher than that obtained with farmer’s practices of 14.81 q ha-1. In spite of increase in yield of chickpea, technological gap, extension gap and technology index existed which was 4.06, 4.13 q ha-1 and 17.67 per cent, respectively. The extension gap can be bridged by popularizing package of practices where in stress need to be laid on improved variety, use of proper seed rate, balanced nutrient application and proper plant protection measures. Improved technologies gave higher net return of Rs. 67727 ha-1 with benefit cost ratio 4.88 as compared to local check (Rs. 50487 ha-1, benefit cost ratio 4.22).
