The aim of this article is to explore ways of increasing agricultural productivity in Zimbabwe in the face of the increasingly uncertain climatic conditions. Agriculture has remained crucial to economic growth in Zimbabwe while it is mainly rain-fed. The total seasonal rainfall amounts are not indicating any significant trend (increasing or decreasing) with time. Changes are only noticed in the...

暖地二毛作水田での乾田直播栽培において効果的に雑草防除を行うためには，乾田期間に播種後土壌処理剤と入水前茎葉処理剤の2回処理が必要であるが，より省力的な防除技術の開発が求められている。そこで本研究では，播種後土壌処理剤のプロメトリン・ベンチオカーブ乳剤（以下PB剤）とトリフルラリン乳剤（以下T剤）の混用処理による1回防除体系を検討した。試験は2019年～2021年の3か年実施した。2019年と2021年は適度な降雨があったが，2020年は播種前後が極端に乾燥した年であった。3か年の試験を通して，播種後3日目～10日目にPB剤とT剤を混用処理すると，イネ科雑草及び広葉雑草に対して安定して高い除草効果を得られることが明らかとなった。PB剤は1葉期までのノビエに登録があることから，処理時期を播種後3日目以降とすることで初期発生のイネ科雑草を枯殺するとともに，T剤との混用により土壌処理効果が...

The experiment entitled “Impact of different tillage and nutrient management strategies on productivity profitability direct seeded rice (Oryza sativa L.)” was conducted in an ongoing trial at the Agronomical Research Farm (plot no. 5) Tirhut College Agriculture, Dholi (RPCAU, Pusa) during Kharif 2019. laid out a ‘split-plot design’ with practices under main plot treatments as subplot treatment...

Growth rates of seedlings of eight tropical rain forest tree species were compared under five different canopy openness levels (FU and 50, 200, 800, 3200 m gaps). RGR exhibited a positive relation with canopy openness with species attaining their highest RGR at the 800 m (4 species) or 3200 m (3 species) gaps. Seed mass and RGR were negatively related. The increase in RGR between small and larg...

The aim of this study was to engineer skeletal muscle tissue for repair abdominal wall defects. Myoblast were seeded onto the scaffolds and cultivated in vitro for 5 days. Full thickness abdominal wall defects (3 x 4 cm) were created in 18 male New Zealand white rabbits and randomly divided into two equal groups. The defects of the first group were repaired with myoblast-seeded-bovine tunica va...

PURPOSE This experiment aims to investigate the potential ability of mesenchymal stem cells (MSCs) to produce beneficial factors for corneal recovery when the cells were seeded on a xenogeneic acellular corneal matrix (ACM) in vitro. METHODS MSCs and corneal limbal stem cells (LSCs) from the corneal limbus region of rats were isolated and cultured. Batch 1 from each type of cell was seeded on...
