The variety has satisfactorily passed the Proposed Variety Trial (PVT) conducted in the farmers’ field in Boro 2019-20 season. As a result National Seed Board (NSB) approved this variety for commercial cultivation in the Boro season (dry season) in 2021. It has modern plant type with 101 cm plant height and matures by 148 days. The proposed variety showed 1.20 t/ha higher yield than check variety BRRI dhan84. Identifying characters of this variety are green leaf, intermediate plant height, erect flag leaf, medium slender grain, intermediate leaf senescence grain. It can produce 7.7 - 8.8 t/ha grain yield. Thousand grain weight of the variety is 16.7 gm and head rice yield is 64%. The rice has zinc content 25.7 mg/kg, 26.8% amylose content with 7.8% protein content. The zinc enriched BRRI dhan100 is a superb variety for cultivating in the Boro season (dry) and farmers can be economically benefited and the country will be nutritionally benefited by the cultivation of BRRI dhan100.</p> Md.

The experiment was laid out in RCBD with a split-plot arrangement having three replications. Wheat was sown in different sowing dates i.e., October 24<sup>th</sup>, November 2<sup>nd</sup>, 12<sup>th</sup>, and 22<sup>nd</sup> in main plots, whereas five wheat varieties (Chounth # 1-2010, Moqawim-09, Shisham Bagh-08, Dar-ul-Aman-07 and Solh 2002) were in sub plots. November 2<sup>nd </sup>planted wheat had a highest biological yield of (6642.1 kg ha<sup>-1</sup>) followed by October 24<sup>th</sup> and November 12<sup>th</sup> which gave (6576.5) and (5711.0 kg ha<sup>-1</sup>) respectively. The lowest biological yield of (2975.1 kg ha<sup>-1</sup>) was given by the wheat varieties sown on November 22<sup>nd</sup>. Among the all-wheat varieties, Solh 2002, had significantly higher biological yield of (6263.7 kg ha<sup>-1</sup>) followed by Shisham Bagh-08 with biological yield of (5571.8 kg ha<sup>-1</sup>). However, Moqawim-09 had lowest biological yield of (4976.8 kg ha<sup>-1</sup>) compare to other varieties. While, evaluating performance of different wheat varieties on different sowing dates, Solh 2002, resulted in maximum biological yield (7476.2 kg ha<sup>-1</sup>) on November 2<sup>nd</sup> followed by Dar-ul-Aman-07 (6933.3 kg ha<sup>-1</sup>) and Shisham Bagh-08 (6860.0 kg ha<sup>-1</sup>) on November 2<sup>nd</sup> and October 24<sup>th</sup> respectively. On the other hand, Dar-ul-Aman-07 had lowest biological yield among the varieties (2015.5 kg ha<sup>-1</sup>) on November 22<sup>nd</sup>, it shows that, Dar-ul-Aman-07 had highest biological yield on early planting but lower yield on late sowing dates. The study shows that delay in wheat planting or selection of other varieties rather than Solh 2002 and Dar-ul-Aman-07 reduces the biological yield of the crop.</p> Sediq Omar Roshan Rahmatullah Hashimi Ghulam Habib Noori ##submission.copyrightStatement## 2021-07-01 2021-07-01 9 15 10.9734/aprj/2021/v8i130165 Evaluation of the Organ Microscopy, Chemical Composition and Anti-inflammatory Potentials of Methanolic Leaf Extract and Fractions of Diaphananthe bidens <p><strong>Aim: </strong>The study aims to investigate high-pressure liquid chromatographic (HPLC)-based chemical composition and anti-inflammatory activity of methanolic leaf extract and fractions of <em>D. bidens</em>.</p> <p><strong>Study Design: </strong>The study is a laboratory-based research involving collection, identification and preparation, of plants, extraction, characterization and evaluation of the anti-inflammatory potential of <em>D. bidens.</em></p> <p><strong>Place and Duration of Study: </strong>Department of Pharmacognosy and Traditional Medicine, Faculty of Pharmaceutical Sciences, Nnamdi Azikiwe University, Awka, Nigeria between January 2016 and June 2019.</p> <p><strong>Methodology: </strong>Powdered leaves of <em>D. bidens</em> was macerated in methanol and the obtained crude extract was fractionated using <em>n</em>-hexane, ethylacetate, butanol, and water respectively. The acute toxicity profile of the extract was determined. Spectroscopic factors of the plant were assayed using HPLC-DAD and the anti-inflammatory activity of the extract and its fractions were evaluated.</p> <p><strong>Results: </strong>Acute toxicity study showed that the crude extract has an LD<sub>50</sub> &gt; 5,000 mg/kg. HPLC-DAD analysis revealed the presence of compounds including apigenin monoglycoside, quercetin 3-O-(6''O-acetyl) galactopyranoside, kaempferol 3-O-(6" O-malonyl) glucoside, genistein 8-C-glucoside, while anti-inflammatory study showed that the extract and fractions inhibited cellular activities of inflammatory mediators (86 – 97 %) in comparison with the diclofenac (53 %); thus, supporting its ethnomedicinal use in the treatment of inflammation.</p> <p><strong>Conclusions: </strong>Methanolic extract of <em>D. bidens</em> has wide margin of safety. It has sufficient deposit of flavonoids which might be responsible for its strong anti-inflammatory activity that is comparable with diclofenac.</p> Immaculeta C. Umeyor Chukwuebuka E.
