The present investigations were undertaken, in which the winter triticale cultivar Twingo was examined, with the aim of analyzing production output, expressed by grain yield and its structure, as affected by different levels of nitrogen and magnesium fertilisation and assess and compare the economic efficiency of production technologies. This research encompassed the results of a three-year (2013-2015) field experiment conducted at the Research Station in Tomaszkowo near Olsztyn, Poland. The experiment was set up in a random, split-plot design, with four replications. The first order factor was nitrogen fertilisation (kg ha-1): 30, 60, 90, 120 and 150. The second order factor was the level of magnesium fertilisation (kg ha-1): 0 and 5 kg MgSO4∙7H2O. Statistical analysis of the results showed that the grain yield was significantly affected by the year of the trial, nitrogen and magnesium fertilisation, interaction of the first and second factors was not proven. The method based on the standard gross margin (SGM) was used for the economic evaluation of the three production technology differentiated costs levels. Three technologies with the highest, medium and lowest average yields were selected to the comparison. Differences in compared technologies concerned to the date and dose of nitrogen and magnesium fertilisation. Results showed, that increasing intensity of winter triticale technology in the field trial, caused the higher financial yield value of winter triticale, as well as direct costs and direct surplus. The direct surplus was higher by 24.4% between the lowest and the highest winter triticale technologies. The highest yield technology was characterized by the highest profitability.

Rice is the most extensively cultivated cereal crops in Bangladesh and nitrogenous fertilizer, especially urea is the most pressing fertilizer to supply nutrient in the paddy field. With this view, an experiment was conducted to evaluate the effect of deep placement and foliar application of urea fertilizer on BRRI dhan29 rice cultivar in boro season at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during December 2015 to May 2016. The experiment was laid out in a randomized complete block design considering twelve treatments with three replications. The treatments were- T0 ( No N application), T1 [140 kg N/ha (as prilled urea)], T2 (1.8 g 1-USG + 5 foliar spray @ 1% N solution), T3 (1.8 g 1-USG + 5foliar spray @ 1.5% N solution), T4 (1.8 g 1-USG + 5 foliar spray @ 2% N solution), T5 (1.8 g 2-USG), T6 (2.7 g 1-USG), T7 (2.7 g 1-USG + 3 foliar spray @ 1% N solution), T8 (2.7 g 1-USG + 3 foliar spray @ 1.5% N solution), T9 (2.7 g 1-USG + 3 foliar spray @ 2% N solution), T10 (1.8 g 2-USG + 3 t/ha cowdung), T11 (2.7 g 1-USG + 3 t/ha cowdung). Results showed that the grain and straw yield of the rice variety responded significantly to the application of prilled urea (PU), deep placement of USG and foliar application of N. The highest grain yield (4.8 t/ha) was recorded in T8 which was identical to the yield (4.7 t/ha) obtained in T3. The highest straw yield (6.0 t/ha) was found in T5. The lowest grain yield (3.7 t/ha) and straw yield (4.5 t/ha) were found in T0. Considering the economic efficiency, the treatment T8 showed the maximum gross margin and marginal gross margin with lowest cost per unit of product. Therefore, to get highest grain yield (4.8 t/ha), 82 kg N/ha as USG and 3 foliar spray of N @1.5% concentration i.e. total 219 Kg urea/ha can be applied to the rice field of BRRI dhan29. This will save an amount of 81 Kg urea per rice growing season per hectare.Res. Agric., Livest. Fish.5(2): 157-164, August 2018

The aim of the study was to evaluate the economic efficiency of production of a hybrid genetic line of winter triticale in comparison with a short-straw form, at different intensity levels under cereal crop rotation conditions. Calculations were made based on three-year (2017-2019) field trial results. The analysis included tillage methods (traditional and simplified), differentiated nitrogen fertilization (0,90 and 120 kg N/ha) and two forms of triticale: The rotondo variety and the hybrid genetic line – BOH 2415. The gross margin was taken as a measure of economic efficiency. The economic effectiveness of cultivation of both forms of winter triticale was assessed from the perspective of utilizing one of the basic production factors, i.e., land. The gross profitability index for particular variants of the experiment was also calculated as the relation of production value to direct costs. The analysis of production and economic indices showed that the more favorable variant of winter triticale cultivation was hybrid form cultivation technology with the use of traditional tillage (plough) and a nitrogen fertilization rate at a level of 120 kg N/ha. The level of the obtained gross margin was more influenced by the level of the obtained yield and the purchase price of triticale than by the level of incurred direct costs depending on the soil tillage method.

AbstractThe experiment was conducted at the Regional Agricultural Research Station, BARI, Ishwardi, Pabna, Bangladesh, during 2013-2014 and 2014-2015 to introduce maize as relay crop with T. Aman rice under different agronomic practices for determine the production potentials. The experiment was design split plot with three replications. The agronomic management practices included four plant spacing viz. S1=75 cm×20 cm (66666 plants/ha), S2=60 cm×20 cm (83333 plants/ha), S3=50 cm×20 cm (100000 plants/ha) and S4=40 cm×20 cm (125000 plants/ha) and four soil management practices viz. M1=soil mulching at 25 DAE, M2=earthing up at 25 DAE, M3=straw mulching at 25 DAE and M4= without earthing up and mulching (control). Seeds were relayed by dibbling manually in 10 days before the harvest of T. Aman rice. Results showed that an increasing plant spacing increased leaf area Index (LAI), total dry matter (TDM), crop growth rate (CGR) and light energy interception (LEI). Grain yield was higher in S3spacing (8.44 t/ha) than others (S48.11 t/ha, S27.34 t/ha and S16.89 t/ha). Among the soil management practices, M2increased LAI, TDM, CGR, LEI as well as grain yield. Moreover, M2and M1gave similar grain yield (8.22 t/ha and 8.02 t/ha), that were significantly greater than other two soil management practices (M37.55 t/ha and M46.98 t/ha). From the economic point of view, combination of S3M1gave better performance with gross margin of Tk. 95000/ha and BCR of 2.17. On the basis of results, S3M1combination was suitable for growing maize under relay sowing with T. Aman rice.

A range of precision farming technologies are used commercially for variable rate applications of nitrogen (N) for cereals, yet these usually adjust N rates from a pre-set value, rather than predicting economically optimal N requirements on an absolute basis. This paper reports chessboard experiments set up to examine variation in N requirements, and to develop and test systems for its prediction, and to assess its predictability. Results showed very substantial variability in fertiliser N requirements within fields, typically >150 kg ha−1, and large variation in optimal yields, typically >2 t ha−1. Despite this, calculated increases in yield and gross margin with N requirements perfectly matched across fields were surprisingly modest (compared to the uniform average rate). Implications are discussed, including the causes of the large remaining variation in grain yield, after N limitations were removed.

The aim of the study was to compare the production and economic effects of different winter rye depending on their production technologies. The study was carried out based on the results obtained from a field experiment conducted in two growing seasons (2018/2019 and 2019/2020). These experiments were conducted in Wielichowo Agricultural Experimental Station, belonging to the Institute of Soil Science and Plant Cultivation – the State Research Institute in Puławy (Poland). The result of the study was the determination of economic efficiency indicators for two cultivars of winter rye varieties according to production technology The technologies differed in terms of the degree of consumption of means of production. The studies showed a significant influence of production technology intensity on the yields of winter rye cultivars. Intensive technology resulted in a significant increase in grain yield. The tested cultivars yielded higher under intensive production technology. The cultivation of winter rye according to intensive technology compared to integrated technology resulted in a significant increase in grain yield . The grain yield increase for the KWS Vinetto cultivar was 0.13 t/ha, while for the Dańkowskie Granat cultivar 0.20 t/ha. Research showed that the level of production intensity determined the amount of direct costs as well as the profitability of production in a given technology. The compared technologies ensured the profitability of winter rye grain production. Both production technologies ensured the profitability of production of the tested cultivars of winter rye. The most profitable direct profitability index was characteristic for the population cultivar Dańkowskie Granat grown under the integrated technology.

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.

Yam (Dioscorea spp.) is a valuable food security crop in West Africa, where 92% of the world production occurs. The availability of quality seed tubers for increased productivity is a major challenge. In this study, minitubers weighing 1, 3, and 5 g produced from virus-free single-node vine cuttings of two improved yam varieties (Asiedu and Kpamyo) growing in an aeroponics system were assessed for suitability in seed production at a population of 100,000 plants ha−1. A 3 × 2 factorial experiment with randomized complete block design and three replications was set up during the cropping seasons of 2017 to 2019 at the International Institute of Tropical Agriculture Research Station in Kubwa, Abuja, Nigeria. Results showed field establishments of 87%–97.8%. Yields differed with minituber size, variety, and cropping season; the highest was 31.2 t ha−1 in 2019 and the lowest, 10 t ha−1 in 2018 from 5 and 1 g Kpamyo minitubers, respectively. The estimated number of tubers produced per hectare by 1, 3, and 5 g minitubers was 101,296, 112,592, and 130,555, with mean weights per stand of 159.2, 187.3, and 249.4 g, respectively. We recommend using less than 6 g minitubers for seed yam production due to their high multiplication rates.

The efficacy of seed treatment and foliar spray with fungicides in controlling black point incidence of wheat seeds was evaluated in the field. Two seed treating fungicides, namely Vitavax-200 and Homai-80WP were used @ 0.25% of dry seed weight and foliar spray with Tilt-250EC (0.05%) was applied in six different schedules. Untreated and unsprayed controls were also maintained. Seed treatment with either Vitavax-200 or Homai-80WP significantly increased plant population and grain yield, but none of them was found effective in reducing black point incidence. On the other hand, foliar sprays with Tilt-250EC under all the spray schedules except spraying at 70 and 90 DAS significantly minimized the disease severity over unsprayed control. Among the different spray schedules, spraying at 30, 40, 50, 60, 70, 80, and 90 DAS appeared to be most effective, which was similar to spraying at 30, 45, 60, 75, and 90 DAS in reducing black point incidence and increasing grain yield. Economic analysis on yield advantage showed that the highest additional gross margin of Tk. 6120/ha with BCR 2.57 was obtained from five sprays applied at 30, 45, 60, 75, and 90 DAS. Key Words: Seed treatment, foliar spray, black point, wheat. DOI: 10.3329/bjar.v34i3.3968 Bangladesh J. Agril. Res. 34(3) : 425-434, September 2009
