Overview

Randomized block trial demonstrates increased grain yield and net returns from combined lime and nitrogen in maize on acidic nitisols, highlighting an optimal nutrient management strategy.

Key Points

To determine the effects of integrated agricultural lime and nitrogen fertilizer application rates on the growth, grain yield, and economic profitability of maize grown on acidic nitisols.
Conducted a field experiment using a randomized complete block design (RCBD) with ten treatments replicated three times in Burie district, Ethiopia.
Tested combinations of lime (0 and 0.5 t ha⁻¹) and nitrogen fertilizer (0, 100, 200, 300, and 400 kg ha⁻¹) using maize variety BH-661, with a uniform base of 200 kg ha⁻¹ diammonium phosphate.
Combined application of 0.5 t ha⁻¹ lime and 400 kg ha⁻¹ nitrogen shortened days to tasseling from 88 to 85 days and silking from 91 to 88 days, with grain yield positively correlated with biomass (r=0.996) and harvest index (r=0.987).
Adjusted maize grain yield increased by 13.42% from 5,550 kg ha⁻¹ to 6,410.20 kg ha⁻¹, which was 40.3% higher than the regional average of 3,780 kg ha⁻¹, with maximum agronomic use efficiency reaching 3.76%.
Economic evaluation revealed a maximum net benefit of 47,701.04 Ethiopian Birr, establishing 0.5 t ha⁻¹ lime combined with 300 kg ha⁻¹ nitrogen as the economically optimal recommendation.
