Yield And Quality

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to study the yield and quality of aromatic fine rice as affected by variety and nutrient management during the period from June to December 2013. The experiment comprised three aromatic fine rice varieties viz. BRRI dhan34, BRRI dhan37 and BRRI dhan38, and eight nutrient managements viz. control (no manures and fertilizers), recommended dose of inorganic fertilizers, cowdung at 10 t ha-1, poultry manure at 5 t ha-1, 50% of recommended dose of inorganic fertilizers + 50% cowdung, 50% of recommended dose of inorganic fertilizers + 50% poultry manure, 75% of recommended dose of inorganic fertilizers + 50% cowdung and 75% of recommended dose of inorganic fertilizers + 50% poultry manure. The experiment was laid out in a randomized complete block design with three replications. The tallest plant (142.7 cm), the highest number of effective tillers hill(10.02), number of grains panicle (152.3), panicle length (-1 -122.71cm), 1000-grain weight (15.55g) and grain yield (3.71 t ha-1) were recorded in BRRI dhan34. The highest grain protein content (8.17%) was found in BRRI dhan34 whereas the highest aroma was found in BRRI dhan37 and BRRI dhan38. The highest number of effective tillers hill(11.59), number of grains panicle (157.6), panicle length (24.31 cm-1-1) and grain yield (3.97 t ha-1) were recorded in the nutrient management of 75% recommended dose of inorganic fertilizers + 50% cowdung (5 t ha-1). The treatment control (no manures and fertilizers) gave the lowest values for these parameters. The highest grain yield (4.18 t ha-1) was found in BRRI dhan34 combined with 75% recommended dose of inorganic fertilizers + 50% cowdung, which was statistically identical to BRRI dhan34 combined with 75% of recommended dose of inorganic fertilizers + 50% poultry manure and the lowest grain yield (2.7 t ha-1) was found in BRRI dhan37 in control (no manures and fertilizers). The highest grain protein content (10.9 %) was obtained in the interaction of BRRI dhan34 with recommended dose of inorganic fertilizers which was as good as that of BRRI dhan38 and 75% of recommended dose of inorganic fertilizers + 50% poultry manure. The highest aroma was found in BRRI dhan38 combined with 75% recommended dose of inorganic fertilizers + 50% cowdung.J. Bangladesh Agril. Univ. 12(2): 279-284, December 2014

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during December 2014 to May 2015 to study the effect of integrated fertilizer and weed management on the yield and gain protein content of aromatic Boro rice (cv. BRRI dhan50). The experiment comprised six sets of fertilizer managements. 1. Negative control having no fertilizers and no manures, 2. Recommended dose of inorganic fertilizers (i.e. Urea, TSP, MoP, Gypsum, ZnSO4 @ 250, 120, 120, 100, 10 kg ha-1, respectively), 3. 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 4. 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 5. 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1, 6. 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1.  Four weed managements 1. Control (no weeding), pre-emergence herbicide, 2. Panida 33 EC + one hand weeding at 35 DAT, 3. Post-emergence herbicide, Granite 240 SC + one hand weeding at 35 DAT and 4. Pre-emergence herbicide, Panida 33 EC + post-emergence herbicide, Granite 240 SC. The highest grain yield (6.40 t ha-1), grain protein content (7.79%) and benefit cost ratio (2.20) were obtained from 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 while their corresponding lowest values were found inweedy check without fertilization. Weed infestation reduced 58.28% grain yield in control plots due to crop-weed competition compared to plot receiving pre-emergence herbicide + post-emergence herbicide. It can be concluded that 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 combined with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 may be used to obtain the highest grain yield and grain protein content of aromatic Boro rice (cv.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during January to June 2016 to observe the effect of water, nutrient and weed management practices on the yield and quality of aromatic Boro rice (cv. BRRI dhan50). The experiment consisted of three water managements viz. conventional flood irrigation, AWD (Alternate Wetting and Drying) and SRI (System of Rice Intensification); two nutrient managements viz. recommended dose of inorganic fertilizers (Urea, TSP, MoP, Gypsum, ZnSO4 @ 250, 120, 120, 100, 10 Kg ha-1, respectively) and 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha-1; and three weed managements viz. weedy check (control), two hand weeding at 20 and 40 DAT, and pre-emergence herbicide (Rifit 33EC) followed by post emergence herbicide (Fast klin 10WP) application. The highest number of effective tillers hill-1, grains panicle-1,grain yield and protein (%) in grain were obtained in SRI water management which was followed by AWD and conventional flood irrigation. Between the two nutrient management practices, application of 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha-1 produced higher number of effective tillers hill-1,grains panicle-1,1000-grain weight, grain yield and protein (%) in grain than in organic fertilizer. Among the weed management practices, application of pre-emergence herbicide (Rifit 33EC) followed by post-emergence herbicide (Fast Klin 10WP) produced the highest number of effective tillers hill-1,grains panicle-1,1000-grain weight, grain yield and protein (%) in grain followed by two weedings at 20 and 40 DAT while the lowest grain yield was obtained in weedy check. The highest number of effective tillers hill-1,grains panicle-1, grain yield and protein (%) in grain was found in SRI water management combined with 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha-1 and application of pre-emergence herbicide followed by post-emergence herbicide. So, it may be concluded that, to get the highest grain yield in aromatic Boro rice, SRI method along with application of 25% less than recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha-1 and applying pre-emergence herbicide (Rifit 33EC) followed by post emergence herbicide (Fast Klin 10WP) could  be recommended.

Combined application of organic and inorganic fertilizers can play an important role for increasing yield and quality of soybean. Therefore, a field experiment was conducted at Genetics and Plant Breeding farm, Bangladesh Agricultural University from July to November, 2011 to evaluate the effect of cowdung and poultry manure with chemical fertilizer on the yield and quality of soybean cv. BINA soybean-2. The experiment was laid out in randomized complete block design having 9 treatments viz. control (CT), 100% recommended dose of chemical fertilizers (RDCF100%), 50% RDCF (RDCF50%), cowdung 10 t ha-1 (CD10 t ha-1), 50% RDCF + CD 5 t ha-1 (RDCF50% + CD5 t ha-1), 75% RDCF + CD 3 t ha-1 (RDCF75% + CD3 t ha-1), poultry manure 3 t ha-1 (PM3 t ha-1), 50% RDCF + PM 1.5 t ha-1 (RDCF50% + PM1.5 t ha-1) and 75% RDCF + PM 1 t ha-1 (RDCF75% + PM1 t ha-1) with 3 replications. All the treatments significantly influenced the yield, yield attributing parameters and protein content except oil content of BINA soybean-2. The highest plant height, yield, branches plant-1, filled pods plant-1, grain plant-1 and 100-grain wt. were found in RDCF100%, which were statistically identical with RDCF75%+PM1 t ha-1 and RDCF75%+CD3 t ha-1 and the lowest values of all the parameters were obtained from control treatment. The maximum protein content was observed in RDCF100%, which was identical to RDCF75%+PM1 t ha-1 and RDCF75%+CD3 t ha-1 and the lowest value was found in control. The overall finding of this study indicated that organic manure in combination with the recommended dose of chemical fertilizers can be applied to achieve better yield and quality of soybean as well as to improve soil fertility status.

A field experiment was conducted at the Horticultural Farm of Bangladesh Agricultural University, Mymensingh during the period from November 2007 to March 2008 to study the effect of integrated nutrient management on nodulation and sustainable soybean production. There were significant differences among the different treatment combinations in terms of yield and yield contributing characters. Integrated nutrient management with application of 50% of the recommended doses of urea, TSP, MOP, gypsum and biofertilizer (Bradyrhizobium) at the rate of 1 kg ha-1 significantly increased most of the parameters, such as the highest plant height, number of nodule per plant, nodule dry weight per plant, pods per plant, grains per pod, grain yield, oil and protein contents. Coinoculation of Bradyrhizobium seemed to help reduce the NPKS requirement in soybean cultivation. Overall results indicate that the application of integrated nutrient management of biofertilizer (Bradyrhizobium) with ½ NPKS of the recommended dose would produce the best quality of soybean with higher nodulation and yield.

A 2-year study conducted to determine the effect of integrated nutrient management on yield and quality of basmati rice varieties in non-traditional area with 54 plots in split plot design. Variety HUBR 10-9 produced 18.8% higher mean grain yield and superior quality parameters than HUBR 2-1. Mean milling, head rice recovery, amylose content and alkali digestion value noted higher with HUBR 10-9 by 4.1%, 4.1%, 8.5% and 15.1% over HUBR 2-1, respectively. Addition of 75% recommended dose of fertilizers with 25% recommended dose of nitrogen as farmyard manure produced higher mean values by 3.1%, 4.2% and 4.0% for hulling, milling and head rice recovery respectively over 100% recommended dose applied as inorganic sources. Combined use of bio-inoculants (blue green algae plus Azospirillum) exhibited higher values for yield and quality parameters. HUBR 10-9 be grown using 75% recommended dose of fertilizers with 25% nitrogen as farmyard manure and blue green algae plus Azospirillum for enhancement in yield and quality in non-traditional areas of eastern Uttar Pradesh. Further investigation required under diverse conditions.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh from June to December 2015 to investigate the effect of spacing and fertilizer management on the yield of transplanted Aman rice cv. BRRI dhan39. The experiment comprised of five spacings viz. 25 × 5 cm, 25 × 10 cm, 25 × 15 cm, 25 × 20 cm, 25 × 25 cm and four fertilizer schedules viz. no manure and no fertilizer (control), recommended dose of inorganic fertilizer (80-60-40 kg N, P2 O5 , K2 O ha-1, respectively + 60 kg ha-1 gypsum + 10 kg ha-1 ZnSO4 ), 75% recommended dose of inorganic fertilizer + cow dung at 5 t ha-1, 75% recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. Plant height (104.60 cm), number of total tillers hill-1 (11.03), panicle length (22.25 cm), grains panicle-1 (109.00) and grain yield (4.42 t ha-1) were found to be the highest in 25 × 15 cm spacing. Regarding nutrient management, 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 superseded other treatments in terms of plant height (107.50 cm), number of total tillers hill-1 (10.40), number of effective tillers hill-1 (7.68), panicle length (22.26 cm), grains panicle-1 (111.70) and grain yield (4.14 t ha-1). The control treatment (no manures and no fertilizers) gave the lowest values for all these parameters. The highest grain yield (4.57 t ha-1) was found in 25 × 15 cm spacing combined with 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 and the lowest grain yield (2.50 t ha-1) was found in 25 × 5 cm spacing combined with control (no manures and fertilizers). Therefore, 25 × 15 cm spacing combined with 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 appeared as the promising practice in transplant Aman rice cv. BRRI dhan39 cultivation.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from December 2013 to May 2014 to evaluate the integrated use of poultry manure with prilled urea and USG for improving the growth, yield and protein content of aromatic Boro rice (cv. BRRI dhan50). The experiment was laid out in a randomized complete block design with three replications. The experiment comprised 14 treatments viz. control (no manure and no fertilizer), recommended dose of prilled urea (115 kg N ha-1), urea super granules (USG) 1.8 g (55 kg N ha-1), USG 2.7 g (80 kg N ha-1), poultry manure (PM) 2.5 t ha-1, PM 5 t ha-1, recommended dose of prilled urea + PM 2.5t ha-1, recommended dose of prilled urea + PM 5 t ha-1, 50% of recommended dose of prilled urea + PM 2.5 t ha-1, 50% of recommended dose of prilled urea + PM 5 t ha-1, USG 1.8 g + PM 2.5 t ha-1, USG 1.8 g + PM 5 t ha-1, USG 2.7 g + PM 2.5 t ha-1and USG 2.7 g + PM 5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. Morphological characteristics, yield contributing characters and yield of aromatic Boro rice (cv. BRRI dhan50) were significantly influenced by integrated use of poultry manure with prilled urea and  USG. USG 2.7 g + PM 5 t ha-1 gave the highest plant height, number of tillers hill-1 and total dry matter production at all sampling dates while their corresponding lowest values were recorded in control. The highest yield contributing characters viz. number of effective tillers hill-1 (13.08), grains panicle-1 (124.26g) and 1000-grain weight  (21.41g) were recorded in USG 2.7 g + PM 5 t ha-1 and the lowest values were recorded in control. The highest grain yield (5.33 t ha-1) and protein content (7.49%) were obtained at USG 2.7 g + PM 5 t ha-1 which was as good as recommended dose of prilled urea (115 kg N ha-1) + PM 5 t ha-1, USG 2.7 g + PM 2.5 t ha-1, USG 1.8 g + PM 5 t ha-1, recommended dose of prilled urea (115 kg N ha-1) + PM 2.5 t ha-1 while the lowest one (2.00 t ha-1) was obtained in control plots. The integrated use of poultry manure (5 t ha-1) with USG 1.8 g (55 kg N ha-1) appeared as the promising practice because of reducing considerable amount of prilled urea or USG in aromatic Boro rice (cv. BRRI dhan50) cultivation in terms of grain yield and grain protein content.Progressive Agriculture 27 (2): 86-93, 2016

Crop and nutrient management options could improve the yield performances of late transplant Aman rice which is generally lower compared to optimum transplanting. To address these issues, an experiment was conducted at Bangladesh Agricultural University, Mymensingh to investigate the effect of spacing and nutrient management options on yield and yield components of late transplant Aman rice and to find out the better treatment combination to obtain higher yield. The experiment was laid out in two factors randomized complete block design (RCBD) with three replications consisting of three spacings viz. S1 =25 cm×15 cm , S2 =25 cm×10 cm and S3 =20 cm×10 cm; and eight nutrient management options viz. N0 = Control (No fertilizer), N1 = Poultry manure @ 5 t ha-1 , N2 = Vermicompost @ 3 t ha-1 , N3 = Researcher’s practice (Urea, TSP, MoP, Gypsum and ZnSO4 @ 180,75,105, 60 and 7.5 kg ha-1, respectively), N4 = 75% N3 + Poultry manure @ 2.5 t ha-1, N5 = 50% N3+ poultry manure @ 5 t ha-1, N6 = 75% N3+ Vermicompost @ 1.5 t ha-1 and N7 = 50% N3+ Vermicompost @ 3 t ha-1. Pre-germinated seeds of BRRI dhan46 were sown in wet nursery bed on 16 August and 30–d–old seedlings were transplanted as per treatments on 15 September in 2017. Yield and yield components were significantly influenced by spacing, nutrient management options and their interactions. The highest yield (5.20 t ha-1) was obtained the spacing 25 cm×10 cm which was at par with 25 cm×15 cm (5.12 t ha-1) and the lowest (4.88 t ha-1) was in 20 cm×10 cm. Statistically similar grain yield 5.85, 5.81 and 5.79 t ha-1 were produced in the treatments N3, N4 and N6, respectively. Grain yield increased in the treatments having combination of inorganic and organic nutrient, and also in the optimum inorganic fertilizers (researcher’s practice). The highest grain yield (5.98 t ha-1) was obtained in the interaction S2×N3 which was at par with S1 x N3, S1 x N4, S1 x N6, S2 x N4 and S2 x N6. Performances of sole organic fertilizers were not satisfactory level. Therefore, reduced amount (75%) of inorganic fertilizers combined with organic fertilizers (poultry manure 2.5 t ha-1 or vermicompost 1.5 t ha-1) along with closer spacing 25 cm×10 cm would be recommended to achieve better and sustainable yield performance of late transplant Aman rice cv.

For sustainable boro rice production in Bangladesh, a balanced fertilization to improve the current soil condition caused by mono-application of inorganic fertilizers and appropriate rice variety selection are very crucial. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the boro season of December 2016 to May 2017 to evaluate the effect of integrated nutrient management on two boro rice cultivars. The varieties were BRRI dhan28 and BRRI dhan29 and eight kinds of nutrient management viz., control (no fertilizers), recommended dose of inorganic fertilizers (120-60-40 N, P2O5, K2O kg ha-1 + gypsum 60 kg ha-1 and ZnSO4 @ 10 kg ha-1), full dose of poultry manure @ 5 t ha-1, cowdung @ 10 t ha-1, poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of other inorganic fertilizers, cowdung @ 5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers, poultry manure @ 2.5 t ha-1 + 75% prilled urea and full dose of inorganic fertilizers, and cowdung @ 5 t ha-1 + 75% prilled urea and full dose of other inorganic fertilizers. The experiment was laid out in a split plot design with three replications. Result showed that, yield and yield components of boro rice were significantly influenced by variety, nutrient management and interaction of variety and nutrient management. In respect of grain yield, BRRI dhan29 produced the maximum yield (5.46 t ha-1). BRRI dhan28 showed poor performance with all characters and gave the minimum yield (4.07 t ha-1). In case of nutrient managements, the highest yield and yield component were obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers and produced the maximum grain yield (5.70 t ha-1). In the interaction of variety and integrated nutrient management, the highest grain yield (6.83 t ha-1) and straw yield (7.61 t ha-1) was obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers with BRRI dhan29 variety. So, BRRI dhan29 with 2.5 t ha-1 poultry manure + 50% prilled urea and full dose of the recommended inorganic fertilizers might be a promising practice for boro rice cultivation.

Grain Yield And Quality

Cultivation of malting barley is particularly challenging as the requirements of growers, for high yield, and that of the brewing industry, seeking a specific quality criteria, must be met simultaneously. Furthermore, significant genotypic and environmental variations in grain yield and quality properties may occur. To investigate the relationships between grain yield and quality parameters of spring malting barley, a 2-year experiment was carried out in order to characterise the genotypic and year effects on grain yield, quality properties, and yield components of 23 high-yielding varieties of spring malting barley under optimal nitrogen (N) fertilisation. Compared to the grain quality properties of the grain protein content and the grain retention fraction of grain size >2.5 mm, less genotypic and environmental variation in grain yield was observed. Grain yield was closely related to spikes per m2, suggesting the importance of tiller formation and establishment as a decisive factor influencing malting barley yields. A major interactive effect of genotypes and year on grain size was observed. Regarding weather effects, the global radiation intensity during the post-anthesis phase was the major factor affecting the final grain size in this study. Grain protein content was primarily dependent on the year effect, suggesting that optimal N fertilisation levels must vary between years to ensure the correct protein content required for the needs of the brewing industry is met. Therefore, we recommend further development strategies addressing N fertilisation and soil N mineralisation to optimise the production of spring malting barley.
