A field experiment was conducted at Agronomy Field Laboratory, Patuakhali Science and Technology University, Dumki, Patuakhali from July 2018 to November 2018 to evaluate the effect of sunflower residues and herbicides on the yield and economic performance of transplanted Aman rice. Weed control methods tested were T1 = weedy check (Unweeded control), T2 = Weed-free check by hand weeding twice, T3 = Pendimethalin, T4 = Pretilachlor, T5 = Butachlor, T6 = Pyrazosulfuron ethyl, T7 = Bensulfuron methyl + Acetachlor, T8 = Bispyriback sodium, T9 = 2,4-D amine, T10 = MCPA, T11 = Sunflower residues, T12 = Sunflower residues + 100% Pyrazosulfuron ethyl, T13 = Sunflower residues + 75% Pyrazosulfuron ethyl, T14 = Sunflower residues + 50% Pyrazosulfuron ethyl. The experiment was laid out in a randomized complete block design with fourteen treatments replicated thrice. Weedy check registered significantly the highest total weed density (354.67 m-2) and total weed dry matter (51.81 g-2) while weed-free treatment by hand weeding twice recorded significantly the lowest total weed density (6.67 m-2) and total weed dry matter 0.49 g-2) . Weedy check produced the highest weed index (34.24%) and hand weeding produced the lowest. Among different herbicides applied alone, butachlor had the lowest total weed density (15 m-2) and total weed dry matter (6.43 g-2) after hand weeding. Hand weeding recorded the highest grain yield (5.14 t ha-1) which was statistically similar to pendimethalin, pretilachlor, butachlor, bensulfuron methyl + acetachlor and sunflower residues + 100% pyrazosulfuron ethyl. Higher grain yield was attributed to a higher number of panicle m-2, number of filled grains panicle-1 and 1000-grain weight. The highest gross margin (22955 Tk. ha-1) and benefit-cost ratio (1.32) were obtained from butachlor. Integration of sunflower residues with pyrazosulfuron ethyl produced effective weed suppression and satisfactory yield comparable to butachlor. Although the integration is less profitable than butachlor the farmers can use this technology as a feasible and environmentally sound approach in transplanted Aman rice field. Bangladesh Agron.

The experiment was conducted at Multi Location Testing (MLT) site, Moulvibazar, Bangladesh during rabi season of 2016-17 and 2017-18 to study the profitability of intercropping of hybrid maize with vegetables and spices. Five intercrop combinations of hybrid maize along with sole maize were arranged in randomized complete block design (RCBD) replicated six times. There were six treatments viz., T1: Maize + potato, T2: Maize + red amaranth, T3: Maize + spinach, T4: Maize+ data shak, T5: Maize + coriander and T6: Maize as sole. The grain yield of maize in intercropped combination varied significantly. The highest grain yield (9.71 t ha-1) was in sole maize. The highest maize equivalent yield 15.60 t ha-1 was recorded from the treatment T1 (100% maize + potato) whereas the lowest yield (8.61 t ha-1) was obtained from the treatment T6 (sole maize). The highest gross return (Tk. 312000 ha-1) and benefit cost ratio (3.29) was obtained from the treatment T1 (100% maize + potato). On the contrary, the lowest gross margin (Tk. 101600 ha-1) was obtained from treatment T2 (maize + red amaranth). It revealed that the combination of maize with potato was more compatible and profitable intercropping system in Sylhet region of Bangladesh Bangladesh Agron. J. 2018, 21(2): 73-78

A field experiment was conducted at Jute Research Experimental Station, Manikganj, Bangladesh during 2017 and 2018 cropping seasons to study the feasibility of intercropping leafy vegetables at early stage of the fibre crop: kenaf along with conventional weeding methods for better weed suppression and higher productivity. A Randomized Complete Block Design (RCBD) was followed consisting of eight treatments with three replications. Three leafy vegetables: red amaranth, jute shak and kangkong were used as intercrop with kenaf following 1 hand weeding and 1 hand hoeing alternately. Sole kenaf (weeded twice) was also grown as control. The total weed vegetation was comprised of grasses 49%, broadleaved 33% and sedge only 18%. Performance of kangkong as intercrop was found better in terms of weed suppression. Hand weeding was found more efficient as a cultural weeding method in reducing weed density. Although intercropping resulted in significant yield reduction of kenaf but increased net return and benefit-cost ratio (BCR) by increasing kenaf equivalent yield (KEY). The land equivalent ratio (LER) was found higher in all intercropping treatments than sole kenaf which indicated more efficient utilization of land under intercropping. Red amaranth intercropping+1 hand weeding resulted the maximum gross return (TK.1,36,200 ha-1) while the highest gross margin (Tk. 59,390 ha-1) and BCR (1.78) was obtained from jute shak intercropping+1 hoeing. Considering the production cost, monetary return and productivity, Kenaf intercropped with Jute shak+1 hoeing was found better than other intercropping treatments. SAARC J.

An experiment was conducted in farmer’s field with the aim to evaluate the effect of integrated use of bioslurry and inorganic fertilizer on the agroeconomic performance of transplanted aus rice (t. aus) (cv. BRRIdhan42) in AEZ 20. The trial was laid out in a randomized complete block design with three replications. There were three treatments viz., T1: soil test based inorganic fertilizer dose for high yield goal (HYG), T2: cowdung (CD) slurry @ 5 t ha-1 with integrated plant nutrition system (IPNS) basis inorganic fertilizer dose for HYG and T3: Farmer’s practice (average of 20 farmers fertilizer dose). The highest mean grain yield (3.93 t ha-1) of t. aus rice was obtained from the treatment T2 followed by T1 (3.46 t ha-1). Gross return, gross margin and benefit cost ratio were also observed higher in T2. Therefore, fertilizer package NPKSZn @ 56-4-20-9-1 kg ha-1 + cow dung slurry @ 5 t ha-1 in IPNS approach might be helpful for getting higher grain yield of t. aus rice and maintaining sustainable soil health as well.Bangladesh J.

The experiment was conducted at multilocation testing (MLT) site, Sujanagar, Pabna during the year of 2003-2004 to find out a soil test based economically viable fertilizer recommendation for the cropping pattern Boro-T. aman. Six treatments viz., moderate yield goal (MYG), high yield goal (HYG), integrated plant nutrient system (IPNS), recommended fertilizer of FRG' 97 (BARC) guide (RF), farmers' practice (FP), and absolute control were employed for the study. The grain yield of Boro and T. aman rice increased 18 and 14%, respectively, by IPNS compared to farmers' practice. Total grain yield of rice was increased by about 16% in the IPNS fertilizer package compared to farmers' practice. Fertilizer nutrients supplied both from organic and inorganic sources in adequate amount have a positive effect on productivity of soil. On an average it was found that highest grain yields of Boro rice (5.37 t/ha) and T. aman (4.49 t/ha) were obtained from integrated plant nutrient system (IPNS) where farmers’ practice gave yield of 4.55 and 3.94 t/ha. The highest average gross margin (70385 Tk./ha) and marginal benefit cost ratio (3.78) was also obtained from IPNS plots. Keywords: Crop productivity; fertilizer management; cropping pattern.

ABSTRACT Maize–sweet potato intercropping often results in weed suppression and increased crop productivity. This study was designed to determine the appropriate planting time and optimal density of sweet potato in a maize-sweet potato intercropping system that will minimize weed infestation and improve yield of the component crops in a drought-prone southern Guinea savanna of Nigeria. The experiment was laid as a randomized complete block design with a split-plot arrangement and 3 replications in 2018 and 2019 growing seasons. The main plots were planting time (May, June and July) while the sub-plots consisted of 3 maize-sweet potato intercropping populations(maize at 53,333 plants/ha + 33,333 plants/ha of sweet potato, maize at 53,333 plants/ha + 66,666 plants/ha of sweet potato and maize at 53,333 plants/ha +99,999plants/ha of sweet potato), sole maize at 53,333 plants/ha and sole sweet potato at 33,333 plants/ha. The results revealed that, 7 weed species were the most prevalent and there was inconsistent effect of planting date on weed flushes while weed smothering efficiency of intercropping was between 31 to 49 % and 48 to 73% for weed density and weed biomass, respectively. Intercropping resulted in land equivalent ratios (LER) of 1.29 to 1.74 while the competitive ability of maize was increased with an increase in sweet potato density. Planting in the month of June had significantly higher tuber yield of 9.56 t/ha of sweet potato and maize grain yield of 3.28 t/ha while intercropping 33,333 plants/ha of sweet potato (1 vine of sweet potato planted at 0.40m apart on the ridge and 0.75m between ridges) and maize at 53,333 plants/ha (0.25m x 0.75m) gave an intercrop yield of 7.32 t/ha tubers and 3.46 t/ha grain yield with highest LER of 1.74, a net profit of ₦566,435.00 and benefit cost ratio of 1.44 was relatively similar to sole sweet potato. Therefore, the above intercropping pattern established in the month of June will minimize weed infestation and improve productivity of maize and sweet potato in the southern Guinea savanna of Nigeria.

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.

The integrated use of chemical and organic fertilizers can help in sustainable and environmentally sound nutrient management of soils. A study was conducted in the farmer’s field of Godaghari, Rajshahi from February to May 2012 to investigate the effect of integrated nutrient management on nutrient uptake by rice cv. NERICA 10 and economization of inputs. Six treatments viz. T1 = Control, T2 = RFD for MYG + cowdung @ 5 t ha-1, T3 = RFD for HYG, T4 = RFD for HYG + cowdung @ 5 t ha-1, T5 = RFD for HYG + cowdung @ 5 t ha-1 based on IPNS, and T6 = RFD for HYG + 10% excess fertilizer of HYG were used. The experiment was laid out in a randomized complete block design with three replications. Results showed that the uptake of N, P, K, S, Ca and Mg by both grain and straw of rice were statistically significant due to use of integrated nutrient management. The highest nutrient uptake was recorded from the treatment T5 and the lowest value was obtained from control. Combined application of cowdung @ 5 t ha-1 along with recommended chemical fertilizers based on IPNS was more economic compared to other treatments because maximum benefit cost ratio was calculated from this treatment. The overall results suggest that integrated nutrient management can be used as an alternate option of chemical fertilization to achieve maximum yield, nutrient uptake and cost of return for rice cv.

The experiment was conducted at Multi Location Testing (MLT) site, Netrakona during rabi season of 2009-10 and 2010-11 to study the feasibility of intercropping of hybrid maize with different short duration vegetables and economic returns. Three intercrop combinations of hybrid maize along with sole maize were arranged in Randomized Complete Block Design replicated six times. There were four treatments viz., T1- Sole crop of maize, T2 - Three rows of red amaranth (25 cm apart) in between two (75 cm apart) rows of Maize, T3 - Three rows of bush bean (25 cm apart) in between two (75 cm apart) rows of Maize and T4 -Three rows of garden pea (25 cm apart) in between two (75 cm apart) rows of Maize. Yield contributing characters and yield of maize did not varied significantly due to intercropping with vegetables. The grain yield of maize in intercropped combination varied from 7.30-7.43 t/ha. But the highest grain yield (7.68 t/ha) was in sole maize. Maize equivalent yields in the intercrops ranged from 10.67-14.96 t/ha. The highest maize equivalent yield (14.96 t/ha), gross return (Tk. 224400/ha), gross margin (Tk.166830/ha) and benefit cost ratio (3.90) were obtained in maize + garden pea combination. The lowest maize equivalent yield (7.68 t/ha), gross return (Tk. 115200/ha), gross margin (Tk. 64128/ha) and benefit cost ratio (2.26) were obtained from sole crop of maize.

The study was carried out at Multi Location Testing site, Sujanagar, Pabna during two consecutive years of 2011-12 and 2012-13 growing season to assess the performance of the pattern with newly released crop varieties against the existing one usually practiced by the farmers with traditional varieties in order to increase yield and economic return. The experiment was laid out in a randomized complete block design with six dispersed replications at farmer’s field. In improved pattern (IP) BARI Gom-26, BARI Til-4 and Binadhan-7 variety were used for wheat, sesame and T. aman rice, respectively. On the contrary in existing pattern (EP) farmers usually use BARI Gom-21, local (char shira) and Sharna cultivar for wheat, sesame and T. aman rice, respectively. The mean yield was recorded 4.66, 1.34 and 4.79 t ha-1 from wheat (BARI Gom-26), sesame (BARI Til-4) and T. aman (Binadhan-7) respectively from the improved cropping pattern whereas average yield 3.81, 0.98 and 4.58 t ha-1 was obtained from wheat (BARI Gom-21), sesame (local) and T. aman (Sharna), respectively from the existing pattern. Two years mean data also showed that improved pattern provided about 18% higher REY compared to existing pattern. Sustainable yield index and production efficiency were also found maximum with improved cropping pattern. Similarly, maximum gross margin and benefit cost ratio were obtained from improved cropping pattern. Bangladesh Agron. J. 2018, 21(2): 13-18
