Dry matter partitioning, yield and grain protein content of fine aromatic boro rice (cv. BRRI dhan50) in response to nitrogen and potassium fertilization

An experiment was conducted to study dry matter partitioning, yield and grain protein content of fine aromatic Boro rice (cv. BRRI dhan50) in response to nitrogen and potassium fertilization. The experiment consisted of four levels of nitrogen viz., 0, 50, 100 and 150 kg/ha and four levels of potassium viz., 0, 30, 60 and 90 kg/ha. The results revealed that at growth stage, the highest total dry matter partitioning and accumulation were obtained from 150 kg N/ha along with 90 kg K/ha at physiological maturity stage. At harvest, the highest number of tillers/hill (8.58), number of grains/panicle (113.9), grain yield (5.15 t/ha) and grain protein content (8.30%) were obtained from 100 kg N/ha along with 90 kg K/ha. Total dry matter partitioning and accumulation were greatly influenced by the application of 150 kg N/ha along with 90 kg K/ha. Application of 100 kg N/ha along with 90 kg K/ha interaction appeared as the promising practice in fine aromatic rice (cv. BRRI dhan50) cultivation in terms of yield and grain protein content.

Boro Rice

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during December 2017 to May 2018 to study growth performance of aromatic Boro rice (cv. BRRI dhan50) in response to nitrogen and potassium fertilization. The experiment consisted of four levels of nitrogen viz., 0, 50, 100 and 150 kg ha-1, and four levels of potassium viz., 0, 30, 60 and 90 kg ha-1. The experiment was laid out in a randomized complete block design with three replications. The results revealed that nitrogen and potassium fertilization and their interaction exerted significant influence on growth performance of BRRI dhan50. Application of 100 kg N ha-1 produced the tallest plant (82.17 cm), the highest number of tillers hill-1 (10.08) and chlorophyll content (52.21) at heading stage. While, application of 90 kg K ha-1 produced the tallest plant (81.44 cm) at physiological maturity stage, the highest number of tillers hill-1 (9.66) and chlorophyll content (51.54) at heading stage. In case of interaction, the tallest plant (85.33 cm), the highest number of tillers hill-1 (10.83) and chlorophyll content (58.28) were obtained from 100 kg N ha-1 along with 90 kg K ha-1 at heading stage. Therefore, application of 100 kg N ha-1 along with 90 kg K ha-1 interaction appeared as the promising practice in aromatic rice (cv. BRRI dhan50) cultivation in terms of growth performance.

Days After Anthesis

The changes which occurred in grain protein content with maturity of three sorghum (Sorghum bicolor (L.) Moench) genotypes were investigated at four nitrogen (N) application levels, 0, 35, 70 and 140 kg/ha. Three sorghum genotypes (RCFA × L.187, L.187 and SK 5912) were field-grown at Samaru, Zaria, Nigeria. Grain was sampled at 10, 17, 24 and 67 days after anthesis and grain protein was determined by Kjeldahl methods. The concentration of grain protein of RCFA × L.187 and L.187 increased up to 24 days after anthesis with a peak at 17 days after anthesis in 1977 while in SK 5912, the highest concentration was at 10 days after anthesis in that year. In 1978, the concentration trend was similar to that in 1977 but the behavior of SK 5912 was erratic because an increase in grain protein concentration occurred at 17 days after anthesis only in plants grown on soil supplied with 35 and 70 kg N/ha. In all other treatments, the grain protein concentration of this genotype decreased from 10 to 67 days after anthesis. However, total grain protein yield per hectare increased significantly in all genotypes at harvest over that at 10 days after anthesis.Key words: Sorghum bicolor (L.)

N Rates

Barley (Hordeurn vulgare) cvv. Grimmett, Galleon and Corvette were grown under irrigated conditions at The University of Queensland, Gatton College. to determine the effects of nitrogen (N) rates (0-200 kg N/ha) on plant growth, yield and grain protein content. Nitrogen delayed maturity in all cultivars, especially in Galleon. Total tiller number and fertile tiller number were increased by N and there was a significant cultivar x N rate interaction. Similar trends were evident in total dry matter at maturity and grain yield, with Galleon producing the highest yields. Fertile tiller percentage was reduced by increasing N rate. Grain protein content increased with the increasing N rate, with differences in the nature of the response between cultivars (i.e. linear in Corvette, quadratic in the other 2 cultivars). Total and fertile tiller numbers were explained by quadratic regressions, with maximum values at 150 kg N/ha (except fertile tillers in Grimmett, maximum value at 100 kg N/ha). The declines in fertile tiller percentage were explained by quadratic equations except in Grimmett, which showed a negatively linear response to increasing N rate. Dry matter yield and grain yield showed quadratic responses to N in Grimmett and Galleon (predicted maximum values near 200 kg N/ha) and linear responses in Corvette, over the experimental range of N rates. The response in grain protein content was explained by quadratic equations for Grimmett and Galleon, with minimum grain protein content occurring at close to 0 and 55 kg N/ha respectively. Corvette showed a linear increase in protein content in response to increasing N rate. It is concluded that plant breeding programs should consider variation in grain yield and protein content in response to N supply and select for efficiency of utilisation of N. Recommended N rates for irrigated barley could be 150-200 kg N/ha. Lower rates will promote strong yield responses, but protein content would remain low.

Boro Rice

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

Mutant Lines

Deficiency of metals, primarily Fe and Zn, affects over half of the world’s population. Human diets dominated by cereal products cause micronutrient malnutrition, which is common in many developing countries where populations depend heavily on staple grain crops such as wheat, maize, and rice. Biofortification is one of the most effective approaches to alleviate malnutrition. Genetically stable mutant spring wheat lines (M7 generation) produced via 100 or 200 Gy gamma treatments to broaden genetic variation for grain nutrients were analyzed for nutritionally important minerals (Ca, Fe, and Zn), their bioavailability, and grain protein content (GPC). Variation was 172.3–883.0 mg/kg for Ca, 40.9–89.0 mg/kg for Fe, and 22.2–89.6 mg/kg for Zn. In mutant lines, among the investigated minerals, the highest increases in concentrations were observed in Fe, Zn, and Ca when compared to the parental cultivar Zhenis. Some mutant lines, mostly in the 100 Gy-derived germplasm, had more than two-fold higher Fe, Zn, and Ca concentrations, lower phytic acid concentration (1.4–2.1-fold), and 6.5–7% higher grain protein content compared to the parent. Variation was detected for the molar ratios of Ca:Phy, Phy:Fe, and Phy:Zn (1.27–10.41, 1.40–5.32, and 1.78–11.78, respectively). The results of this study show how genetic variation generated through radiation can be useful to achieve nutrient biofortification of crops to overcome human malnutrition.
