The economic rate of nutrients was determined with eight different fertilizer treatment applied on T. aman rice (var. Binadhan-7) in Old Brahmaputra Floodplain Soils (AEZ-9) during 2012 and 2013 at Trisal, Mymensingh. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The treatment combinations were: T1 (N64 P14 K28 S6 Zn1), T2 (N80 P14 K28 S6 Zn1), T3 (N80 P17.5 K28 S6 Zn1), T4 (N80 P14 K35 S6 Zn1), T5 (N64 P17.5 K35 S6 Zn1), T6 (N80 P17.5 K35 S6 Zn1), T7 (N48 P10.5 K21 S4.5 Zn0.75), and T8 (control). Grain and straw yields were significantly affected by the application of fertilizers at different rates. Results revealed that the average highest grain (4.86 t ha-1) was recorded in T6 (N80 P17.5 K35 S6 Zn1) treatment and straw yield (5.34 t ha-1) was recorded in treatment T3 (N80 P17.5 K28 S6 Zn1) which is 132.54% and 86.06% respectively higher over control treatment. The second highest grain yield (4.77 t ha-1) was obtained in T3 treatment and straw (5.18 t ha-1) was recorded in T6 treatment. Average (2012 & 2013) nutrient uptake (grain and straw) was the highest in T3 treatment. Partial budget analysis demonstrated the highest net benefit of Tk. 69,673 ha-1 in T6 followed by Tk. 68,833 ha-1 in T3 and the highest MBCR (4.29) was obtained in T3 treatment. The present investigation suggests that treatment T3 (N80 P18 K28 S6 Zn1) might be the best profitable fertilizers dose to sustain Binadhan-7 rice production in Old Brahmaputra Floodplain Soils.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22096 J.

The effect of different rates of boron application on wheat cv. Bijoy was studied through a field experiment at    Bangladesh Agricultural University (BAU) farm, Mymensingh during 2009-10 rabi season. The BAU farm belongs to    Old Brahmaputra Floodplain agroecological zone (AEZ 9). Texturally the soil was silt loam, with 7.2 pH, 0.81%    organic matter and 0.15 mg kg-1 available boron content. The experiment was laid out in a randomized complete    block design with five boron rates and four replications. Boron rates were 0, 0.75, 1.5, 2.25 and 3.0 kg ha-1, with boric    acid as a source. Every plot received blanket doses of 115 kg N, 25 kg P, 75 kg K and 15 kg S ha-1 from urea, TSP,    MoP and gypsum, respectively. Treatment receiving B @ 2.25 kg ha-1 produced the highest grain yield (4.22 t ha-1) which was statistically identical with that obtained with 1.75 kg B ha-1. However, the crop response curve showed    1.90 kg ha-1 to be the optimum boron rate for the maximization of wheat yield. The lowest grain yield (2.84 t/ha) was    recorded with control treatment. There was a positive relationship between grain yield and number of grains spike-1.   Boron had significant influence on N, P, K, S and B uptake by the crop which, in deed, was more influenced by crop    yield and less by nutrient concentration, except N and B uptake where concentration had more influence than yield.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.10987   J.

An experiment was conducted to study the yield response and nutrient uptake of rice (BRRI dhan30) to reduced rates of N, P and K from the recommended fertilizer doses (RFD). The experiment was laid out in a randomized complete block design with four replicates. There were ten treatments viz. T1 (control), T2 (RFD), T3 (RFD - 20% N), T4 (RFD - 40% N), T5 (RFD - 20% P), T6 (FRD - 40% P), T7 (RFD - 20% K), T8 (RFD - 40% K), T9 (RFD - 20% NPK) and T10 (RFD - 40% NPK). The recommended fertilizer doses of the crop were 100 kg N, 20 kg P, 40 kg K, 20 kg S and 3 kg Zn ha-1. The highest grain yield (5.10 t ha-1) and straw yield (7.02 t ha-1) were obtained by applying recommended doses of fertilizers which were insignificantly different from those observed in the treatments where N, P and K were reduced at the rate of 20% from the recommended doses. Similar results were also found in case of P, K and S content and uptake by rice plant, while the variation for N was found significant. Overall results indicated that 20% reduction of either N or P or K from the recommended doses would not significantly affect the yield of rice.

A study was conducted to determine the direct and residual effects of phosphate rock (PR) on the growth and yield of wheat cv. Kanchan during Rabi season of 2004-2005 at the Bangladesh Agricultural University farm, Mymensingh. The experiment was designed with four treatments and was laid out in a Randomized Complete Block Design (RCBD) with four replications. The treatments were: T1: control (0 kg P ha-1), T2: PR (26 kg P ha-1), T3: TSP (26 kg P ha-1), and T4: PR (210 kg P ha-1 applied in previous crop to cover 6 succeeding crops). Dry matter yield at panicle initiation (PI) stage was significantly influenced by the treatments. Effective tillers hill-1 and grains panicles-1 varied significantly with P treatments. The highest grain yield (3.10 t ha-1) and straw yield (5.54 t ha-1) were found in T3 treatment. Economic analysis demonstrated that the highest net benefit of Tk. 24,788 ha-1 was obtained in T3 treatment which was followed by Tk. 22,964 ha-1 and Tk.12,292 ha-1 in T4 and T2, respectively. The highest net benefit was obtained from T3 treatment due to higher grain and straw yields.DOI: http://dx.doi.org/10.3329/agric.v10i1.11062The Agriculturists 2012; 10(1): 31-37

Four field experiments were carried out with Binadhan 7 at Birgonj, Dinajpur; Debigonj, Panchagarh; Kaligonj, Lalmonirhat and Pirgonj, Rangpur during T.aman (kharif II) season of 2011 in the Old Himalalayan Piedmont Plain (AEZ 1) and Tista Meander Floodplain Soils of North-West Bangladesh. The experiments were designed with eight treatments and laid out in randomized complete block design (RCBD) with three replications. The treatment combinations were: T1 (100%STB), T2 (T1 + 25% N), T3 (T1 + 25% NP), T4 (T1 + 25% NK), T5 (T1 + 25% PK), T6 (T1 + 25% NPK), T7 (75% of T1) and T8 (Control). Results indicated that application of different fertilizers significantly affected the grain yield at all of the four locations. The highest grain yield was found in treatment T6 (T1 + 25% NPK). Statistically identical yield was observed in treatments T3, T4 and T5 at Dinajpur; T3 at Panchagar; T2, T3, and T4 at Lalmonirhat and T2 at Rangpur. All the treatment combinations gave significantly higher grain yield over the control at all of the locations. The highest straw yield was found in treatment T6 (T1 + 25% NPK). Statistically identical straw yield was found in T3 and T4 at Dinajpur; T1, T4 and T5 at Panchagar; T2, T4, T5 and T7 Lalmonirhat and all treatments except T7 and T8 at Rangpur. Significantly the lowest yield was obtained in the control treatment (T8) in all of the locations. The highest total N uptake was observed in treatment T6 at all of the four locations. For total P uptake, the similar trend of total N uptake was observed for all the locations. Treatment T6 showed the highest uptake of total K at all locations. The highest uptake of total S was observed in treatment T6 at Dinajpur, Panchagarh and Lalmonirhat. But the highest uptake of total S was observed in treatment T3 at Rangpur. However, the lowest total N, P, K and S uptake was observed in control treatment (T8) at all locations. The partial budget analysis of T.aman rice demonstrated the highest net benefit of tkha-1 85,598/-, 78,619/-, 58,308/- and 72,532/- in T6 treatment followed by tkha-1 76,348/- in T4 treatment, 71,100/- in T3 treatment, 54,192/- in T3 treatment and 68,247/- in T2 treatment where the highest MBCR of 5.40, 3.75, 2.20 and 3.84 was also observed in T6 treatment at Dinajpur, Panchagarh, Lalmonirhat and Rangpur, respectively. Based on most profitable treatments, fertilizer doses of N80P8K40S8Zn1 in Birgonj, Dinajpur; N84P8K40S6Zn1 in Debigonj, Panchagarh; N80P8K40S6Zn1 in Kaligonj, Lalmonirhat and N81P8K35S8Zn1 in Pirgonj, Rangpur could be recommended for higher yield of Binadhan-7 rice in North-West Bangladesh.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22106 J.

A field experiment was conducted to find out the effect of nitrogen levels and transplanting dates on the yield and yield components of aromatic rice cv. Kalizira. The experiment was laid out in a randomized complete block design with three replications using four( 0, 50, 100, and 150 kg N ha-1 ) levels of nitrogen and three transplanting dates (10 August, 22 August and 04 September, 2007 ) along with the basal doses of triple super phosphate (TSP), muriate of potash (MoP) and gypsum. The study revealed that most of the yield and yield contributing characters with few exceptions were significantly influenced by nitrogen levels and transplanting dates. They had significant positive effect on tillers hill-1, tillers hill-1, grains panicle-1 and straw yield. The highest grain yield (2.63 t ha-1) was observed in 100 kg N ha-1 with 10 August transplanting treatment and straw yield (6.43 t ha-1) was found highest in 150 kg N ha-1 with same date of transplanting and the lowest grain (1.83 t ha-1) and straw yields (5.14 t ha-1) were found in N control treatment with transplanting date of 04 September. The highest grain length (4.68 mm), grain breadth (2.49 mm) and imbibition ratio (6.93) were observed with 100 kg ha-1 N rate coupled with 10 August transplanting, and for length-breadth ratio, the same rate recorded the highest result, but with different transplanting date i.e. 22 August.

An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

Purpose: To evaluate the blended fertilizer formulas types, under unlimed limed condition of Asossa acid soil on soybean in Benishagul Gumuz of Ethiopia. Methods: Two factorial RCB design with three replications was used in the investigation. Five types of blended fertilizer formulas were tested under limed and unlimed condition in Factorial Randomized Complete Block Design. Lime and blended fertilizer types were used as factor. The amount of lime that was applied at each location was calculated on the basis of the exchangeable acidity, bulk density and 15 cm depth of the soil. One mole of exchangeable acidity would be neutralized by an equivalent mole of CaCO3. Accordingly, the amount of lime for this particular activity would be uniformly applied for all plots at 1.5 times of the exchangeable acidity (Equation 1) and incorporated in to the soil a month before seed sowing. Results: The effects of applied lime (CaCO3) and fertilizer types on growth and yield components of soybean were non-significantly (P>0.05) influenced except 100 seed weight, whereas the lime by blended fertilizer types interaction effects were not-significantly (P>0.05) affect all growth and yield components of soybean (Table 2). The highest plant height (71.58 cm) was obtained from NPKSZnB (Formula 5 modified) fertilizer type, however statistically non-significant from the other treatments. Conclusion: The partial budget analysis indicated that, it was not necessarily based on the highest marginal rate of return, rather based on the minimum acceptable marginal rate of return and the treatment with the high net benefit, relatively low variable cost together with an acceptable MRR becomes the tentative recommendation. Therefore we recommend the treatments (100 kg /ha NPSB) that have acceptable marginal rate of return, relatively high net benefit and relatively small total cost of production for soybean production in Asossa zone.

Abstract In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, iron spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2013 on research Farm in Faizabad of Iran, as a split plot within randomized complete block design with three replications. The main plots with irrigation factor and four levels were considered: level A) 50 ml evaporation from pan evaporation; level B) 100 ml evaporation from pan evaporation; level C) 150 ml evaporation from pan evaporation and level D) 200 ml evaporation from pan evaporation. Sub plots were considered with iron spray in three levels, included level A) 80 g/ha, level B) 130 g/ha and level C) 180 g/ha. The drought stress reduced seed yield, the 1000-kernels weight (TKW), the number of seeds per ear, the number of seeds per row in ear, the number of rows per ear about 39%, 6%, 31%, 14% and 27% less than control treatment, respectively. Using iron, as compared with control treatment, causes the increase of 1000-kernels weight from 295 to 311 g and the increase of seed yield from 5188 to 7078. The results obtained from the present research showed that iron spray has fairly improved the effects caused by drought stress.

A pot experiment was conducted at the experimental net house of the Department of Soil Science, Sylhet Agricultural University, Sylhet, Bangladesh to observe the effect of fertilizers on yield and nutrient uptake of local aromatic rice varieties during the Aman season of 2015. The experiment was laid out in a Randomized Complete Block Design with three replications. Five local aromatic rice varieties (Kalizira: V1, Muktasail: V2, Nagrasail: V3, Maloti: V4 and Chinigura: V5) and four packages of fertilizers (F1:  Recommended package i.e. 45-10-20-10-0.5 kg ha-1 of N-P-K-S-Zn, F2: 2/3rd of recommended package, F3: 1/3rd of recommended package, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn source, respectively. According to the treatment, all fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). Nutrient content and uptake of the aromatic rice varieties were significantly affected by the application of different fertilizer packages (with few exceptions). Mostly Kalizira (1.10-0.44-2.31-0.67-13.75 g pot-1 of N-P-K-S-Zn) and/or Nagrasail (1.15-0.46-2.70-0.62-11.74 g pot-1 of N-P-K-S-Zn) varieties showed the highest nutrient uptake in grain and straw with recommended package of fertilizers. While in maximum cases Chinigura (0.41-0.16-0.76-0.197-3.17 g pot-1 of N-P-K-S-Zn) was observed to have the lowest with control treatment. In case of post harvest soil nutrient analyses, Kalizira and/or Chinigura variety associated with recommended package of fertilizers showed the highest nutrient status.

<p>Rate of NPK fertilization on rice using NPK compound fertilizer needs to consider soil nutrient status and plant nutrient requirement. The research was aimed to determine the optimum rate of compound fertilizer and the effect of enriched S nutrient of NPKS compound (15-15-15-5S) and NPK compound fertilizer (15-15-15) on the growth and yield of rice. The experiments were conducted at two sites in Galuga, Ciampea Bogor, West Java from April to September 2013, using randomised complete block design with 3 replications. Experiment at site I consisted of 9 treatments: six levels of fertilizers NPKS i.e. 0; 150; 300; 450; 600; and 750 kg/ha, standard fertilizer, NPK compound fertilizer equivalent to standard, and standard fertilizer plus S. Rate of urea, SP-36, and KCl for standard fertilizer treatment was respectively 250, 75, and 50 kg/ha. At site II the treatments consisted of 6 levels of NPK compound fertilizer i.e. 0; 150; 300; 450; 600; and 750 kg/ha and the standard fertilizer with rate of 250 kg/ha of urea, 50 kg/ha SP-36, and 75 kg/ha KCl. Plot size was 4 m x 5 m planted with Ciherang variety. Data collection included chemical properties of soil before and after the experiment, plant height, number of tillers, straw weight, and dry grain weight and the nutrient uptake. The effectiveness of fertilizer was calculated by RAE (Relative Agronomic Effectiveness). Results showed that fertilizer NPKS (15-15-15-5S) at 600 kg/ha effectively increased dry grain weight from 3.63 t/ha to 4.67 t/ha, but was not significantly different from a standard fertilizer treatment. It increased dry grain weight by 29% compared to control. NPK fertilizer (15-15-15) effectively promoted growth and dry grain weight equivalent to standard fertilizer at rate of 300-750 kgha. The optimum rate of NPK compound fertilizer (15-15-15) was 440 kg/ha as was shown with the production performance of 4.12 t/ha with RAE by 58%. NPKS compound fertilizer with rate of 750 kg/ha showed the highest uptake of N, P, and K nutrients and significantly increased the available P in the soil. Whereas NPK compound fertilizer with a rate of 600 kg/ha indicated the highest P nutrient uptake. Fertilizer enrichment with sulfur on NPKS fertilizer (15-15-15-5S) did not significant affect on grain dry weight.</p>
