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.

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 carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh in transplant Aman season 2008 to find out the effect of urea super granules (USG), prilled urea (PU) and poultry manure (PM) on the yield and yield attributes of transplant Aman rice varieties. Two transplant Aman rice varieties viz. BRRI dhan41 and BRRI dhan46 and ten levels of integrated nutrient management encompassing USG, PU and PM were tested following randomized complete block design with three replications. It was observed that variety BRRI dhan41 gave higher grain yield than BRRI dhan46. For fertilizer effect, the highest grain yield (5.17 t ha-1) was obtained from full dose of USG (1.8g) and other inorganic fertilizers, which was similar to that obtained from full dose of USG (1.8g) + PM at 2.5 t ha-1 followed by full dose of PU + PM at 2.5 t ha-1. The lowest grain yield was obtained in the control treatment. In case of interactions, the highest grain yield was obtained in BRRI dhan41×1.8g USG and other inorganic fertilizers which was similar to that of the same dose of USG with PM at 2.5 t ha-1 and the lowest yield was obtained in the control treatment. It was assessed that a considerable portion (31.25%) of PU nitrogen could be saved by using USG (1.8g) together with other inorganic fertilizers or with PM at 2.5 t ha-1.

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, 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

Reliance on inorganic fertilizers with less or no use of organic fertilizers has impaired the productivity of soils worldwide. Therefore, the present study was conducted to quantify the effects of integrated nutrient management on rice yield, nutrient use efficiency, soil fertility, and carbon (C) sequestration in cultivated land. The experiment was designed with seven treatments comprising of a zero input control, recommended inorganic fertilizers (RD), poultry manure (PM) (5 t ha−1) + 50% RD, PM (2.5 t ha−1) + 75% RD, vermicompost (VC) (5 t ha−1) + 50% RD, VC (2.5 t ha−1) + 75% RD, and farmers’ practice (FP) with three replications that were laid out in a randomized complete block design. The highest grain yield (6.16–6.27 t ha−1) was attained when VC and PM were applied at the rate of 2.5 t ha−1 along with 75% RD. Uptake of nutrients and their subsequent use efficiencies appeared higher and satisfactory from the combined application of organic and inorganic fertilizers. The addition of organic fertilizer significantly influenced the organic carbon, total carbon, total nitrogen, ammonium nitrogen, nitrate nitrogen, soil pH, phosphorus, potassium, sulfur, calcium, and magnesium contents in post-harvest soil, which indicated enhancement of soil fertility. The maximum value of the organic carbon stock (18.70 t ha−1), total carbon stock (20.81 t ha−1), and organic carbon sequestration (1.75 t ha−1) was observed in poultry manure at the rate of 5 t ha−1 with 50% RD. The soil bulk density decreased slightly more than that of the control, which indicated the improvement of the physical properties of soil using organic manures. Therefore, regular nourishment of soil with organic and inorganic fertilizers might help rejuvenate the soils and ensure agricultural sustainability.

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.

Integrated Nutrient Management

This experiment was conducted in the farmer’s field at Khajrauta, Gadhawa-4, Dang, Nepal to evaluate the effect of integrated nutrient management on growth and yield of cauliflower as well as their residual effects on soil properties. The cauliflower variety silvercup-60 was grown under eight different treatments; T1: 50% N through RDF + 50% N through FYM; T2: 50% N through RDF + 50% N through PM; T3: 50% N through RDF + 50% N through VC, T4: 50% N through RDF + 25% N through FYM + 25% N through PM; T5: 50% N through RDF + 25% N through VC + 25% N through PM; T6: 50% N through RDF + 25% N through VC + 25% N through FYM; T7: 50% N through RDF + 25% N through  VC +25% N through FYM; T8: 50% N through RDF + 50% N  through FYM,VC and poultry manure. The experiment was laid out in RCB design with three replications. The result revealed that the  highest plant height (36.40 cm), number of leaves (15), plant spread (31.72 cm), leaf area (526.5 cm2), curd weight (207.3g) and curd yield (12.85 t/ha) were found under 50% N through RDF +50% N through VC. The root length, root diameter and root density were better under all INM treatments as compared to 100% N through RDF. INM treatments showed lesser bulk density, lesser particle density, greater infiltration rate and greater organic matter content than application of 100% N through RDF. Soil total nitrogen was increased in all INM treatments while soil available phosphorus decreases in all treatments except 100% N trough RDF and 50% N through RDF +50% N through PM. Thus, farmers are suggested to apply 50% N through VC along with 50% N through RDF to increase cauliflower yield.

Early Variety

Integrated Nutrient Management (INM) is necessary to enhance sustainable yield in an eco-friendly way. A field experiment was conducted in the research field of Midwest Academy and Research Institute College of Live Sciences, Tulsipur, Dang from November 2018 to January 2019 to investigate the effect of integrated nutrient management on growth and yield of radish. Mino Early variety was used in the experiment. The experiment was laid out on Randomized Complete Block Design with four replications and 5 treatments. Nitrogen (N) was supplied through different sources. The treatment combinations were: control (T1), 100% recommended N through chemical fertilizer (T2), 50% recommended N through chemical fertilizer + 50% N through farmyard manure (FYM) (T3), 50% recommended N through chemical fertilizer + 50% N through poultry manure (T4) and 50% recommended N through chemical fertilizer + 50% vermicompost (T5). Significant effect was noted on leaf numbers, root length, root diameter and yield per ha but no significant effect was noted on the germination percentage and plant height. The highest germination percentage  (77.00 %), plant height (13.27 cm), root length (16.94 cm), root diameter (3.01 cm), and yield per ha (16.55 t/ha) was recorded at T4 (50% recommended N through chemical fertilizer + 50% N through poultry manure). T5 (50% recommended N through chemical fertilizer + 50% vermicompost) recorded the highest leaf numbers (10.40). In our experiment, T4 (50% recommended N through chemical fertilizer + 50% N through poultry manure) was found to be superior, so in inner terai places like Tulsipur, Dang it is suggested to apply 50% recommended N through chemical fertilizer + 50% N through poultry manure to obtain a high yield of radish.

Effect Of Age

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to December 2014 with a view to finding out the effect of age of seedlings at staggered transplanting and nutrient management on growth and yield of aromatic fine grained rice (cv. BRRI dhan38). The experiment consisted of three ages of seedlings (30, 45 and 60 day-old) at staggered transplanting and six nutrient managements viz. control (no nutrients), recommended dose of inorganic fertilizers, 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. The experiment was laid out in a randomized complete block design with three replications. The effect of age of seedlings at staggered transplanting, nutrient management and their interactions were significant on crop characters, yield components and yield of aromatic fine rice. The tallest plant was recorded due to transplanting 30- day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. The highest leaf area index (6.55), number of total tillers hill-1 (12.56), number of effective tillers hill-1 (8.54), panicle length (24.07cm) and number of grains panicle-1 (141.3) were recorded in 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 while the lowest values were recorded in 60-day old seedling with control. In case of sterile spikelets panicle-1, 60-day old seedlings with control treatment showed the highest value (30.94). The highest grain (3.85 t ha-1) and straw (5.29 t ha-1) yields were obtained in 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1. Therefore, 30-day old seedlings fertilized with 75% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1 appeared as the promising technique for appreciable growth and grain yield of aromatic fine grained rice (cv. BRRI dhan38).SAARC J. Agri., 16(1): 49-59 (2018)
