Verification of Soil Test Crop Response Based Phosphorus Calibration Study on Bread Wheat (Triticum aestivum L.) in Bora District of East Shewa Zone, Oromia, Ethiopia
Author(s): Amante Lemma* and Tilahun Firomsa
The verification trial of soil test based crop response phosphorous calibration study for bread wheat production was conducted in 2021/22 main cropping season in Bora district of East Shewa zone. The trial was initiated to verify the phosphorus critical level (10 ppm), requirement factor (6.45 ppm) and optimum amount of nitrogen (69 kg/ha) determined during soil test based crop response phosphorus calibration study for bread wheat production in Bora district. The treatments were control (without fertilizer as T1), farmers practice (blanket recommendation as T2) which was 100 kg of urea and 100 kg of NPS and soil test based recommended phosphorus fertilizer rate as T3. The trial was conducted on six farmers’ field across the district and the trial was laid out in randomized complete block design that was replicated over farmers as replications. The plot size was 10 m × 10 m.. View More»
