Heavy polishing removes bran and germ — and with them much of the fibre, oil, and micronutrients. https://hhhimel.pages.dev/blog/2026-10-18-rooftop-gardening-basics/ https://hhhimel.pages.dev/blog/2026-10-18-rooftop-gardening-basics/ Sun, 18 Oct 2026 12:00:00 GMT Load, waterproofing, containers, soil mix, water, and which crops suit a Dhaka-style roof — a compact checklist before you carry the first bag of soil upstairs. https://hhhimel.pages.dev/blog/2026-10-18-why-fewer-fireflies-and-stars/ https://hhhimel.pages.dev/blog/2026-10-18-why-fewer-fireflies-and-stars/ Sun, 18 Oct 2026 12:00:00 GMT Fireflies need dark nights, clean water, and living edges. City lights and habitat loss hide both the insects and the stars. Small changes at home still help. https://hhhimel.pages.dev/blog/2026-10-08-git-push-rejected-fetch-first/ https://hhhimel.pages.dev/blog/2026-10-08-git-push-rejected-fetch-first/ Thu, 08 Oct 2026 12:00:00 GMT When git push fails with main → main (fetch first) because the remote has commits you do not have locally, pull (or rebase) first, then push — without force-pushing shared history. https://hhhimel.pages.dev/blog/2026-10-07-git-large-file-push-fix/ https://hhhimel.pages.dev/blog/2026-10-07-git-large-file-push-fix/ Wed, 07 Oct 2026 12:00:00 GMT When GitHub rejects a push because a file is over 100 MB, here is a safe sequence: find the offender, remove it from the commit, and push again — without force-pushing shared history. https://hhhimel.pages.dev/blog/2026-10-06-field-notes-2025-blackgram-trial/ https://hhhimel.pages.dev/blog/2026-10-06-field-notes-2025-blackgram-trial/ Tue, 06 Oct 2026 12:00:00 GMT How a blackgram field trial was scored: samples laid on a white sheet with a ruler so every plant is compared the same way, plus what showed up in the plots. https://hhhimel.pages.dev/blog/2026-10-06-soil-moisture-pot-trials/ https://hhhimel.pages.dev/blog/2026-10-06-soil-moisture-pot-trials/ Tue, 06 Oct 2026 12:00:00 GMT Photos from the pot work: staked seedlings, a midday round of probe readings across pots, and a side-by-side comparison of plant condition. https://hhhimel.pages.dev/blog/2026-09-26-lab-to-field-demo/ https://hhhimel.pages.dev/blog/2026-09-26-lab-to-field-demo/ Sat, 26 Sep 2026 12:00:00 GMT A short video tour of a day's work, from the greenhouse nursery to the trial plots, with extra photos below. https://hhhimel.pages.dev/blog/2025-08-12-multi-environment-trials/ https://hhhimel.pages.dev/blog/2025-08-12-multi-environment-trials/ Tue, 12 Aug 2025 12:00:00 GMT Genotype × environment interaction can flip rankings between seasons. Here's how we structure METs, what traits we prioritise, and how selection indices help under Bangladesh's variable climates. https://hhhimel.pages.dev/blog/2025-07-28-field-phenotyping-checklist/ https://hhhimel.pages.dev/blog/2025-07-28-field-phenotyping-checklist/ Mon, 28 Jul 2025 12:00:00 GMT A practical scoring sheet for days to flowering, pod set, pest damage, and stress symptoms — designed for small teams. https://hhhimel.pages.dev/blog/2025-06-15-leaf-to-marker-data/ https://hhhimel.pages.dev/blog/2025-06-15-leaf-to-marker-data/ Sun, 15 Jun 2025 12:00:00 GMT DNA extraction, PCR setup, and common pitfalls when screening diversity panels with molecular markers. https://hhhimel.pages.dev/blog/2025-05-02-trait-associations-blackgram/ https://hhhimel.pages.dev/blog/2025-05-02-trait-associations-blackgram/ Fri, 02 May 2025 12:00:00 GMT Which agronomic and yield components tend to move together — and how that shapes crossing and selection decisions. https://hhhimel.pages.dev/blog/2025-04-10-scouting-pests-without-bias/ https://hhhimel.pages.dev/blog/2025-04-10-scouting-pests-without-bias/ Thu, 10 Apr 2025 12:00:00 GMT How we sample larvae and damage scores so data stay comparable across replicates and seasons. https://hhhimel.pages.dev/blog/2025-03-18-small-plot-trial-design/ https://hhhimel.pages.dev/blog/2025-03-18-small-plot-trial-design/ Tue, 18 Mar 2025 12:00:00 GMT Randomisation, border rows, and simple R layouts for student and early-career breeding experiments.
