Randomized Complete Block Design

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.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December 2004 to evaluate the effect of hill spacing on the performance of BRRI dhan40 and BRRI dhan41 as Transplant aman crop. The experiment consisted of five hill spacings viz., 5cm. 10cm, 15 cm, and 25 cm where row to row spacing of 25 cm was kept constant for all treatments. The experiment was laid out in randomized complete block design with four replications. The 25 cm x 5 cm hill spacing produced the tallest plant, highest total number of tillers/hill, bearing tillers/hill lowest number of non-hearing tillers/hill, grain yield and harvest index, while 25 cm x 5 cm hill spacing produced the highest number of sterile spikelets/panicle, straw yield and biological yield. BRRI dhan41 produced higher grain yield (4.7 t/ha) which was the contribution of higher number of grains/panicle and heavier grain weight. Lower yield (4.51 t/ha) was recorded in BRRI dhan40.Key Words: Varietal performance; T. aman rice; hill density.DOI: 10.3329/bjar.v34i1.5750Bangladesh J. Agril. Res. 34(1) : 33-39, March 2009

An investigation was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University to inspect the effect of vermicompost based nitrogen management and plant spacing on the yield performance of short duration transplant Aus rice (cv. Parija). The study comprised three spacing viz. 20 cm × 20 cm, 20 cm × 15 cm and 20 cm × 10 cm, and five nitrogen management viz. no nitrogen, 75 kg N ha-1, 55 kg N ha-1 + vermicompost @1.25 t ha-1, 35 kg N ha-1 + vermicompost @2.5 t ha-1 and vermicompost @5 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. At harvest, both the spacing of 20 cm × 20 cm and 20 cm × 15 cm produced the tallest plants, the highest number of total tillers hill-1 and effective tillers hill-1. The highest grain yield (3.59 t ha-1) was recorded in 20 cm × 15 cm spacing which was at par with the grain yield (3.52 t ha-1) in 20 cm × 10 cm spacing. The 20 cm × 10 cm spacing also produced the highest straw yield (4.88 t ha-1) and biological yield (8.40 t ha-1). The lowest grain, straw and biological yields were recorded at the wider spacing of 20 cm × 20 cm. In contrast, the highest grain yield (3.79 t ha-1), straw yield (4.99 t ha-1) and biological yield (8.79 t ha-1) were found in 75 kg N ha-1 which was as good as the yields of 55 kg N ha-1 N+ vermicompost @1.25 t ha-1. The highest number of total tillers hill-1 (14.11) and effective tillers hill-1 (12.67) were found in the interaction effect of 20 cm × 20 cm spacing with 75 kg N ha-1. The interaction between 20 cm × 15 cm and 55 kg N ha-1 N+ vermicompost @1.25 t ha-1 gave the highest grain yield (4.58 t ha-1), straw yield (5.71 t ha-1) and biological yield (10.29 t ha-1). The lowest grain yield (2.03 t ha-1), straw yield (3.49 t ha-1) and biological yield (5.52 t ha-1) were found in the interaction between 20 cm × 20 cm and no nitrogen. Therefore, usage of 20 cm × 15 cm spacing fertilized with 55 kg N ha-1 + vermicompost @1.25 t ha-1 appeared as the promising practice of transplant Aus rice cv. (Parija) cultivation.

Brahmaputra Floodplain

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.

High Yielding Varieties

Production and productivity of green gram is governed by environmental, genotypic trait of the crop and crop management. The more specific reason for low production and productivity of pulses is the cultivation of local old varieties under marginally fertile lands and low input management conditions. Recently, high yielding varieties of green gram have been developed and evaluation of these varieties under various management conditions will be of great importance. In this view the study was conducted to investigate the growth and yield response of different green gram varieties in Kitui and Makueni counties in Kenya. Three green gram varieties (KS20, KAT 00308 and KAT 00309) were laid out in a randomized complete block design and replicated three times. The varieties differed significantly (P≤0.05) in plant height, number of effective nodules, 100-grain mass and grain yield in both sites. Variety KS20 was the tallest in both sites in all the stages while KAT00309 was the shortest. Variety (KS20) had the highest number of effective nodules in Ithookwe (11) and Kiboko (39) with the lowest were recorded for variety KAT00308. Days to 50% flowering and maturity were different between the varieties, and KS20 had the shortest where it was recorded that the periods were shorter in Kiboko by >15 days compared to Ithookwe. In both sites, the highest grain yield was recorded for KAT00309 with 2898 kg/ha and 1568 kg/ha in Kiboko and Ithookwe, respectively. There were no signficant differences on the biological yield between the varieties but the 100-grain mass differed signficantly in both sites where variety KAT00309 was the heaviest with 7.8 g and 6.9 g in Kiboko and Ithookwe, respectively. It was concluded that variety KAT00309 could lead to the highest grain yield in both Kitui and Makueni counties under water stress conditions of the two counties.

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during November 2011 to March 2012 to evaluate the effect of integrated use of manures and fertilizers on the growth, yield and nutrient uptake by wheat. There were six treatments such as T0 (Control), T1 [STB-CF (HYG)], T2 [CD + STB-CF (HYG)], T3 [PM + STB-CF (HYG)], T4 [COM + STB-CF (COM)] and T5 [FP (Farmers’ practice)]. The experiment was laid out in a Randomized Complete Block Design with four replications. The integrated use of manures and fertilizers significantly influenced the yield attributes as well as grain and straw yields of wheat. The treatment T1 [STB-CF (HYG)] produced the tallest plant of 90.17 cm which was identical with T3 [PM + STB-CF (HYG)] and the lowest value was found in control. The 1000-grain weight followed the similar pattern but the tillers hill-1, spike length and spikelets spike-1 did not follow any definite trend. The treatment T3 [PM + STB-CF (HYG)] produced the highest grain yield of 4362 kg ha-1 (90.4% increase over control) and straw yield of 5492 kg ha-1 (84.79% increase over control). The lowest grain yield (2291 kg ha-1) and straw yield (2972 kg ha-1) were found in T0 (Control). The NPKS uptake by wheat was markedly influenced by combined use of manures and fertilizers and the treatment T3 demonstrated superior performance to other treatments. So the treatment T3 comprising poultry manure in combination with chemical fertilizers on IPNS basis was found to be the best combination of manures and fertilizers for obtaining the maximum yield and quality of wheat at BAU farm.

Aims: A short term field study was conducted to investigate the yield performance of selected African rice genotypes inoculated with biofertilizers.   Study Design: A randomized complete block design laid out in a split-plot arrangement was used to evaluate response of yield components and grain yield of some selected African rice genotypes will be to mycorrhizal fungi and rhizobium inoculation. Place and Duration of Study: The study was conducted at the Teaching and Research farm of the Federal university of technology, Akure Ondo state, Nigeria during the 2013 planting season. Methodology: The study was laid out in a split plot arrangement in Randomized Complete Block Design (RCBD), with mycorrhizal fungi, rhizobium inoculation and control in the main plot, while genotypes (N-U-1, N-U-8, WAB 56-104, OFADA GR and MOROBEREKAN) were in the sub-plot and treatments were replicated thrice. There were three main blocks, each block consist of 15 sub-plots with a size measurement of 2m x 1m and inter sub-plot spacing of 0.5m in between plots. A total of 50 plants were raised per sub plot. Transplanted seedlings were planted with the soil slurry containing rhizobium and mycorrhizal fungi inoculum into planting holes in the field at two seedlings per stand, according to their respective plot at a spacing of 25cm x 25cm. Yield component data collected include; number of days to 90% maturity, number of days to 50% flowering; plant height at maturity, number of primary tillers per plot, number of grains per panicle, number of panicles, number of filled and unfilled spikelet, weight of 1000 filled grains and grain yield per plot.  Results: Result showed significant (P<0.05) single and interactive effect of rhizobium and mycorrhizal fungi inoculation on rice yield and yield components. 61.4% increase in grain yield was observed in rhizobium inoculated genotypes when compared to 37.4% increase in mycorrhized genotypes and the un-inoculated control. WAB56–104 and N-U-8 had the best interactive response amongst genotypes inoculated with rhizobium while genotypes WAB56-104 and MOROBEREKAN responded better amongst mycorrhized genotypes in relation to yield components. Conclusion: The results from this study indicate that African rice genotypes differ in grain yield response and host specifity when inoculated with mycorrhizal fungi and rhizobium inoculums. However, inoculating specific African rice genotypes with mycorrhizal fungi and rhizobium can positively influence their grain yield and yield component development and this could play an important role in improving African rice productivity.

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during April to November, 2012 to study the combined effects of Sesbania green manure incorporation with different levels of nitrogen fertilizer on the growth and yield of BINA dhan7. There were five treatments for using Sesbania as pre-rice green manure (GM): Fallow (No GM), GM for incorporation at 40, 50, 60, and 70 days after sowing (DAS). T. Aman was planted after chopping the GM. For T. aman there were 9 treatments: Fallow plot received full dose (180 kg urea ha-1) of N fertilizer while plots with GM received 50 and 75% of recommended N fertilizer. The experiment was laid out in a Randomized Complete Block Design with three replications. The highest grain yield of 5752 kg ha-1 and straw yield of 6654 kg ha-1 were observed in the plot treated with 75%recommended dose of nitrogen (RDN) and green manure incorporated at 50 DAS. The lowest grain yield (4783 kg ha-1) and straw yield (5154 kg ha-1) were recorded with GM incorporated at 40 DAS + 50% RDN. The N content and uptake by the grain and straw were differed significantly due to different treatments and maximum uptake was recorded with the application of 75% recommended dose of nitrogen (RDN) and green manure incorporated at 50 DAS. The overall results indicate that application of Sesbania green manure incorporated at 50 DAS in combination with 75% recommended dose of nitrogen could be considered more effective for BINA dhan7 production DOI: http://dx.doi.org/10.3329/sja.v12i2.21925 SAARC J.

Tegra practice (healthy seedling, mechanical transplanting, herbicide application and advisory services), as a new concept in commercial rice cultivation, needs to be evaluated with farmer’s practices in our country. This study was conducted in the farmers’ field during Aman 2013 and Boro 2013-14 seasons in Bogra district. In each season, six farmers within one kilometer radius were selected to conduct this study. Randomized complete block design (RCBD) with two treatments namely farmer’s practices (FP) and Tegra practices (TP) were used in the experiment. Self-propelled four rows walking-type rice transplanter was used to transplant seedling in TP. Seedlings were raised in plastic tray to use in mechanical transplanter. The mat seedlings were ready to transplant when attained 3-4 leaves and 10-12 cm height. Mechanical transplanting found faster than manual transplanting. Missing/floating hill observed insignificant in mechanically transplanted field. Fuel consumption of mechanical transplanter obtained 4.5 L/ha. Tender aged seedling was used in TP and seedling age was higher in FP than TP. Plant height followed the similar trend in both the practices. Tillering ability obtained the highest in TP than FP. TP produced significantly higher (14-23%) grain yield in both seasons. The total cost of production, gross return, gross margin and BCR obtained the highest in TP. BCR showed 5-13% higher in TP than FP in both the seasons due to higher grain and straw yield. The economic analysis clearly revealed the profitability of TP over FP in both the seasons.Bangladesh Rice j. 2016, 20(1): 33-43
