Randomized trial examines yield and growth response of groundnut varieties to phosphorus levels, suggesting optimal application rates.

The aim is to identify the best groundnut variety and phosphorus levels for optimal growth in Kandahar, Afghanistan.
Conducted on a farm in Afghanistan with a split plot design
Tested two groundnut varieties (Kormaki and Paparri) and four phosphorus levels (0, 40, 60, and 80 kg P2O5 ha-1)
Analyzed growth attributes and yield outcomes.
Papparri variety showed significantly higher growth parameters and yields compared to Kormaki
At 60 kg P2O5 ha-1, growth and yield attributes were maximized, including number of pods and weight per plant
Papparri achieved higher gross returns and benefit-cost ratios than Kormaki.

Nazir et al. (2022) studied this question.
