ASRB NET case studies
ASRB NET · Put your knowledge to work in context.
ASRB NET is the National Eligibility Test run by the Agricultural Scientists Recruitment Board, the body that also conducts recruitment for the Agricultural Research Service in India. The NET is an eligibility credential rather than a job offer: qualifying marks you as eligible to apply for Assistant Professor and equivalent teaching or research positions in agricultural universities and institutions that recognise the test. The ASRB NET case studies are 5 cases and about 3,710 words.
1Advancing Wheat Lines from a Six-Location Trial with a Yellow Rust Hotspot
The All-India varietal trial for timely-sown wheat ran at six locations in 2023-24. Twelve advanced lines (F7, pedigree-derived from HD-type parents) were tested in a randomised complete block design with four replications.

A 180-cow crossbred dairy herd (HF x Sahiwal, about 62% HF inheritance) in a peri-urban cooperative averages 14.2 L/day; three months ago it was 16.8 L/day. The bulk milk somatic cell count rose from 210,000 to 640,000 cells/mL over the same period.

A 6.0 ha block of cotton on 1.2 m rows, on a deep sandy loam (field capacity 26% v/v, permanent wilting point 12% v/v, root zone 0.9 m), is to be converted from flood to pressurised irrigation. Peak crop water use is 6.8 mm/day, application efficiency of the existing flood system is 55% and of the proposed sprinkler 75%; rainfall in the peak month is negligible.

A 50,000 L/day toned milk plant uses HTST at 78 °C for 15 s, a plate cooler to 4 °C, and fills 500 mL pouches on a form-fill-seal machine. Over three weeks, 8 of 40 retention samples stored at 6 °C failed the 5-day shelf-life test with off-flavour and curdling, yet every batch released with a negative phosphatase test and a standard plate count below 30,000 cfu/mL on the day of production.

A 250 ha micro-watershed in a semi-arid district was treated in 2015 with 14 check dams, contour trenches on 60 ha, and a 20 ha block of Eucalyptus tereticornis planted on field boundaries and degraded uplands. By 2024 three observations stand out.
