Simulated randomized complete block experiment on moth bean (Vigna aconitifolia) with eight nutrient management treatments in four blocks and eight traits.
Format
A data frame with 32 rows and 10 variables:
- block
Factor, block (R1-R4).
- treatment
Factor, eight treatments (control, recommended dose of fertilizer (RDF), and RDF with biofertilizers, FYM, sulphur or zinc).
- seed_yield
Seed yield (kg/ha).
- plant_height
Plant height at harvest (cm).
- branches_per_plant
Branches per plant.
- pods_per_plant
Pods per plant.
- seeds_per_pod
Seeds per pod.
- test_weight
1000-seed weight (g).
- stover_yield
Stover yield (kg/ha).
- harvest_index
Harvest index (%).
