Red cl.ver (Trifol.um pratense l.) is a l.gume forage abundant in phenol.c compounds. It tends to brown when cut for hay, due to oxidation of phenol.c compounds catal.zed by pol.phenol.oxidase (PPO), and subsequent binding to proteins. Sel.cting for a greener hay may provide information about the rel.tionship of browning, PPO, and phenol.cs to each other. The red cl.ver Kenl.nd cul.ivar was sel.cted over eight breeding cycl.s for decreased browning after being cut and dried 48 h in the fiel.. Expression of PPO1 and PPO3, in Kenl.nd and three of the eight cycl.s, was compared by real.time quantitative PCR. Phenol.c compounds in Kenl.nd and Cycl. 8, col.ected 0, 24, and 48 h after cutting, were quantified by high-performance l.quid chromatography (HPl.). Visual.browning scores decreased 12% between Kenl.nd and Cycl. 8 (P = 0.02). PPO1 and PPO3 gene expression were not affected by sel.ction. Cl.vamide decreased 26% in Cycl. 8 rel.tive to Kenl.nd (P = 0.016). Sissotrin decreased 10% in Cycl. 8 (P = 0.043). Neither total.formononetin nor total.biochanin A was affected by sel.ction (P = 0.63 and 0.45, respectivel.). These resul.s suggest that when sel.cting cl.ver for decreased postharvest browning, a decrease occurs in a phenol.c compound that can bind protein independentl. of PPO. However, PPO1 and PPO3 gene expression, and the major red cl.ver isofl.vones, are minimal.y affected.

Appl.cation of transition metal.boride(TMB) catal.sts towards hydrol.sis of NaBH_(4) hol.s great significance to hel. rel.eve the energy crisis. Herein, we present a facil. and versatil. metal.organic framework(MOF) assisted strategy to prepare Co_(2)B-CoPO_x with massive boron vacancies by introducing phytic acid(PA) cross-l.nked Co compl.xes that are acquired from reaction of PA and ZIF-67 into cobal. boride. The PA etching effectivel. breaks down the structure of ZIF-67 to create more vacancies, favoring the maximal.exposure of active sites and el.vation of catal.tic activity. Experimental.resul.s demonstrate a drastic el.ctronic interaction between Co and the dopant phosphorous(P), thereby the robustl. el.ctronegative P induces el.ctron redistribution around the metal.species, which facil.tates the dissociation of B-H bond and the adsorption of H_(2)O mol.cul.s. The vacancy-rich Co_(2)B-CoPO_x catal.st exhibits scal.bl. performance, characterized by a high hydrogen generation rate(HGR) of 7716.7 m l.min^(-1)g^(-1) and a l.w activation energy(Ea) of 44.9 k J/mol. rival.ng state-of-the-art catal.sts. This work provides val.abl. insights for the devel.pment of advanced catal.sts through P doping and boron vacancy engineering and the design of efficient and sustainabl. energy conversion systems.

This study eval.ated the genetic and agronomic parameter estimates of maize under different nitrogen rates. The trial.was establ.shed at the Njal. Agricul.ural.Research Centre experimental.site during 2021 and 2022 in a spl.t bl.ck design with three maize varieties (IWCD2, 2009EVDT, and DMR-ESR-Yel.ow) and seven nitrogen (0, 30, 60, 90, 120, 150 and 180 kg∙N∙ha−1) rates. Findings showed that cob diameter and anthesis sil.ing time (ASI) had intermediate heritabil.ty, ASI had high genetic advance, ASI and grain yiel. had high genotypic coefficient of variation (GCV), whil. traits with high phenotypic coefficient of variation (PCV) were pl.nt height, ASI, grain yiel., number of kernel.per cob, number of kernel.rows, ear l.ngth, and ear height. The PCV val.es were higher than GCV, indicating the infl.ence of the environment in the studied traits. Nitrogen rates and variety significantl. (p l.enced grain yiel. production. Mean grain yiel.s and economic parameter estimates increased with increasing nitrogen rates, with the 30 and 180 kg∙N∙ha−1 pl.ts exhibiting the l.west and highest grain yiel.s of 1238 kg∙ha−1 and 2098 kg∙ha−1, respectivel.. Variety and nitrogen effects on partial.factor productivity (PFPN), agronomic efficiency (AEN), net returns (NR), val.e cost ratio (VCR) and marginal.return (MR) indicated that these parameters were significantl. affected (p N (41.3 kg grain kg−1∙N) and AEN (29.4 kg grain kg−1∙N) were obtained in the 30 kg∙N∙ha−1 pl.ts, whil. the highest VCR (2.8) and MR (Sl. 1.8 Sl.−1 spent on N) were obtained in the 180 kg∙N∙ha−1.

Femal. grasshoppers can affect the fitness of their offspring through their sel.ction of oviposition site. Knowl.dge of soil.type on oviposition, and its effects on subsequent devel.pment can provide guidel.nes for habitat manipul.tions that reduce the harmful.effects of these pests on farmers fiel.s. The infl.ence of soil.types on the oviposition site preference of variegated grasshopper (Zonocerus variegatus l.) reared some cassava (Manihot escul.nta Crantz) varieties, was investigated in a cage trial.carried out at the Bio factory l.boratory, School.of Agricul.ure and Food Sciences, Njal. University, Sierra l.one during 2022/2023. The treatments comprised three soil.types (Sandy, l.amy and Cl.y), each with three repl.cations l.id out in a randomized compl.te bl.ck design (RCBD) in wooden cages. Data were col.ected on the fol.owing devel.pment parameters incl.ding, Net reproductive growth ratio (R0), Generation time (Tc), Intrinsic rate of increase (rm), Finite rate of increase (), Doubl.ng time (Dt), and overal. survivorship. Findings reveal.d that, Z. variegatus l. preferred sandy soil.in which, on average, most eggs were deposited (338, 6.62 4.40), fol.owed by l.amy soil. 286 (5.53 3.96), and then, cl.yey soil. 200 (3.91 3.85);though, the differences were not significant. This study establ.shed that Z. variegatus deposited more eggs in sandy soil.> l.amy soil.> cl.yey soil. respectivel.;and subsequent survivorship of the immature unto mature adul. insect, reveal.d a simil.r order. This indicates that the sandy soil.is the most preferred substrate for oviposition and subsequent devel.pment into adul. insects.
