The experiment was conducted at the Farm of Farm Management Division, Bangladesh Agricultural University, Mymensingh during December 2012 to June 2013 to find out the effect of plant nutrient and weed management in direct wet seeded Boro rice. The experiment consisted of six nutrient management viz. Control (No manure- PM and N-P-K-S-Zn), PM at 5 t ha-1, recommended dose of prilled urea (PU) and other inorganic fertilizers (i. e. 120, 60, 40, 10 and 5 kg of N, P2O5, K2O, S and ZnSO4, respectively), full dose of Urea Super Granules (USG) and other inorganic fertilizers (i. e. 60, 40, 10 and 5 kg of P2O5, K2O, S and ZnSO4, respectively) 2.7 g USG + PM at 5 t ha-1, 2.7 g USG + PM at 2.5 t ha-1;  and three weeding regimes, viz. Unweeded control, hand weeding thrice at 20, 35 and 50 days after sowing (DAS); and Panida (Pandimethalin) @ 2.5 l ha-1 and hand weeding once at 20 DAS. The highest plant height (90.29 cm) was obtained in full dose of USG and other inorganic fertilizers (i. e. 60, 40, 10 and 5 kg of P2O5, K2O, S and ZnSO4 respectively) and the lowest one (82.42 cm) was from control (No manure- PM and N-P-K-S-Zn). The highest number of effective tillers hill-1 (14.00) was obtained in recommended dose of PU and other inorganic fertilizers (i. e. 120, 60, 40, 10 and 5 kg of N2, P2O5, K2O, S and ZnSO4 respectively) whereas the lowest effective tillers hill-1 9.15 was obtained from control (No manure- PM and N-P-K-S-Zn). The highest number of grains panicle-1 (75.23) was observed in nutrient 2.7 g USG + PM at 5 t ha-1 and the lowest one (59.01) was obtained from PM at 5 t ha-1.The highest plant height (90.57 cm) was obtained in Panida (Pandimethalin) @ 2.5 l ha-1 and hand weeding once at 20 DAS and lowest plant height (83.98 cm) was obtained in un weeded control. The maximum grain yield (3.71 t ha-1) was obtained from the application of 2.7 g USG + PM at 2.5 t ha-1 and the lowest (1.15 t ha-1) was from  control (No manure- PM and N-P-K-S-Zn). The highest grain yield (3.8 t ha-1) was obtained in Panida (Pandimethalin) @ 2.5 l ha-1 and hand weeding once at 20 DAS and the lowest one (1.26 t ha-1) was obtained from unweded control. In case of interaction, the highest number of effective tillers hill-1 (17.00) was obtained in recommended dose of PU and other inorganic fertilizers (i.e. 120, 60, 40, 10 and 5 kg of N, P2O5, K2O, S and ZnSO4 respectively) with hand weeding thrice at 20, 35 and 50 DAS and the lowest one (7.27) was observed in control (No manure- PM and N-P-K-S-Zn) with no weeding. The highest grain yield (5.29 t ha-1) was obtained in  2.7 g USG + PM at 2.5 t ha-1 with Panida (Pandimethalin) @ 2.5 l ha-1 and hand weeding once at 20 DAS which was statistically identical with 2.7 g USG + PM at 5 t ha-1 and Panida (Pandimethalin) @ 2.5 l ha-1 and hand weeding once at 20 DAS and the lowest grain yield (0.65 t ha-1) was obtained in the interaction of unweeded and unfertilized control (No manure- PM and N-P-K-S-Zn). Boro rice (cv. BRRI dhan28) can be cultivated with 2.7 g USG  applied at the centre of the four hills in each alternate row + PM at 2.5 t ha-1 with Panida (Pandimethalin) @ 2.5 l ha-1 and hand weeding once at 20 DAS for appreciable grain yield.Progressive Agriculture 27 (4): 466-472, 2016

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. BRRI dhan50).Int. J. Appl. Sci. Biotechnol. Vol 5(1): 51-58

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.

BRRI dhan50). The experiment comprised six fertilizer managements viz., control (no manures and no fertilizers), recommended dose of inorganic fertilizers (i.e. Urea, TSP, MoP, Gypsum, ZnSO4 @ 250, 120, 120, 100, 10 kg ha-1, respectively), 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1, and 75% of recommended dose of inorganic fertilizers +  poultry manure @ 2.5 t ha-1 and four weed managements viz., control (no weeding), pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + one hand weeding at 35 DAT, post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 + one hand weeding at 35 DAT, pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1. The experiment was laid out in a factorial randomized complete block design with three replications. Growth traits of aromatic Boro rice (cv. BRRI dhan50) were significantly influenced by integrated fertilizer and weed management. Plant height, number of tillers hill-1, total dry matter, leaf area index (LAI) and crop growth rate (CGR) gave their highest values in 75% of recommended dose of inorganic fertilizers and poultry manure @ 2.5 t ha-1 along 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 in control. So it can be concluded that, the interaction of 75% of recommended dose of inorganic fertilizers and poultry manure @ 2.5 t ha-1 along with pre-emergence herbicide (Panida 33 EC @ 2.5 l ha-1) + post-emergence herbicide (Granite 240 SC @ 93.70 ml ha-1) appears as the promising combination in respect of growth performance of aromatic Boro rice (cv. BRRI dhan50).

An experiment was carried out in the farmer’s field of village Boira under Kotoali Thana, District-Mymensingh in Boro season (Jannuary to May 2013) to find out the effect of integrated nutrient management in Boro rice cv. BRRI dhan29 cultivation. The experiment consisted of the following treatments- control (no manure and no fertilizer) (T1), recommended dose of prilled urea and PKSZn (T2), 50% of the recommended dose of prilled urea and PKSZn + cowdung 5 t ha-1 (T3), 50% of recommended dose of prilled urea and PKSZn + poultry manure 2.5 t ha-1(T4), 50% of recommended dose of prilled urea and PKSZn + cowdung 10 t ha-1 (T5), 50% of recommended dose of prilled urea and PKSZn + poultry manure 5 t ha-1 (T6), cowdung 10 t ha-1 (T7), poultry manure 5 t ha-1 (T8), full dose of USG (2.7g) + recommended dose of PKSZn (T9), full dose of USG (2.7g) + cowdung 10 t ha-1 (T10), full dose of USG (2.7g) + poultry manure 5 t ha-1 (T11), full dose of USG (2.7g) + cowdung 5 t ha-1 (T12), full dose of USG (2.7g) + poultry manure 2.5 t ha-1(T13), USG (1.8g) + poultry manure 5 t ha-1 (T14), USG (1.8g) + poultry manure 2.5 t ha-1 (T15) and farmer’s practice (Urea 250 kg ha-1, TSP 220 kg ha-1, MoP 130 kg ha-1, gypsum 130 kg ha-1) (T16). The experiment was laid out in a randomized complete block design with three replications. Results of the experiment showed that integrated nutrient management had significant effect on yield contributing characters and yield of BRRI dhan29. The tallest plant (93.33 cm) was found in T2 treatment (recommended dose of prilled urea and PKSZn), the highest number of total tillers hill-1(16.85) and effective tillers hill-1 (15.90) were obtained in T11 treatment (USG (2.7g) + poultry manure 5 t ha-1). The highest 1000-grain weight (22.40g), grain yield (7.19 t ha-1) and straw yield (8.08 t ha-1) were recorded in T10 treatment (full dose of USG (2.7g) + cowdung 10 t ha-1) and the lowest grain yield (4.43 t ha-1) and straw yield (5.21 t ha-1) were obtained in T7 treatment (cowdung 10 t ha-1). From the study, it can be concluded that inorganic fertilizer along with manure greatly influence the yield contributing characters and yield of Boro rice and full dose of USG (2.7g) with cowdung (10 t ha-1) appears as the promising combination for Boro rice (cv. BRRI dhan29) cultivation.SAARC J. Agri., 13(2): 131-140 (2015)

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, 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 December 2015 to May 2016 to study the effect of age of seedlings at staggered transplanting and weed management on the growth and yield of aromatic Boro rice (cv. BRRI dhan50). The experiment comprised four seedling ages at staggered transplanting viz. 30, 45, 60 and 75-day old seedlings with five different weed management treatments viz. unweeded controls, two hand weeding at 20 and 35 DAT (days after transplanting), pre-emergence herbicide  (Pendimethaiin, Panida 33EC) applied at 3 DAT  + one hand weeding at 35 DAT, post-emergence herbicide (Penoxsulam, Granite 240 SC) applied at 12 DAT  + one hand weeding at 35 DAT, pre-emergence herbicide (Panida 33 EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT. It was observed that the experiment was laid out in a randomized complete block design with three replications. The highest plant height and total dry matter hill–1 were recorded in 30-day old seedlings with pre-emergence herbicide (Panida 33EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT. Younger seedlings (30-days old) produced the highest number of total tillers hill–1 (11.08), effective tillers hill–1 (8.47), grains panicle–1 (80.76) and grain yield (3.94 t ha–1) compared to aged seedlings at staggered transplanting. In case of weed management, pre-emergence herbicide (Panida 33EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT produced the highest number of effective tillers hill-1 (8.89), grains panicle–1 (81.66), 1000-grain weight (18.44 g), grain yield (4.47 t ha–1) and straw yield (5.13 t ha–1). Grain yield was reduced by 59.82% in unweeded control compared to pre-emergence herbicide (Panida 33EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT. In interaction, 30-day old seedlings combined with pre-emergence herbicide (Panida 33 EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT produced the highest effective tillers hill–1 (9.58), grains panicle-1 (89.47), 1000-grain weight (18.93g), grain yield (5.31 t ha–1) and straw yield (5.75 t ha–1). Therefore, 60-day old seedlings at staggered transplanting with pre-emergence herbicide (Panida 33EC) applied at 3DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT appears as the promising technique for aromatic Boro rice cultivation.J.

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.

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.

Given the high costs of agricultural production, especially due to the price of fertilisers, particularly nitrogen, the use of inoculants to supply nitrogen to soybean crops is a widely recommended practice. The objective of this study was to evaluate the feasibility of applying inoculants through seed and planting furrow in soil previously cultivated with soybean and Brazilian native “cerrado” biome soil under greenhouse conditions. Seven treatments were tested: 1) inoculation via seed (inoculant + fungicide + micronutrient), 2) treatment via seed (fungicide + micronutrient), 3) control (only seed), 4) inoculation via furrow-dose 1 (recommended dose), 5) inoculation via furrow-dose 2 (twice the recommended dose), 6) inoculation via furrow-dose 3 (three times the recommended dose) and 7) inoculation via furrow-dose 1 + seed inoculation. We evaluated plant height, fresh and dry matter weight of the aerial part and nodules, number of total, viable and non-viable nodules, number of pods per plant and grain yield. Inoculation was more effective when used in cerrado soil, but soybean performance in treatments without inoculation was higher in previously cultivated soil. Application through furrow proved to be a viable practice due to the similarity of the results obtained with the traditional application by seed.
