| Abstract | A field study on the nutrient requirement of bird chili (Capsicum annuum L.) grown on clay loam soil was conducted at Kanchanaburi Agricultural Research and Development Center in Kanchanaburi province, during 2017-2019. Treatments were laid out in 2x2x2+1 factorial in RCB with three replicates. The treatments were two levels of nitrogen (10 and 20 kg N/rai), two levels of phosphorus (5 and 10 kg P2 O5 /rai) and two levels of potassium (12and24kg K2 O/rai), In total,nine treatments consisted of without fertilizer (0-0-0)and eight treatments of fertilizer, and cow dung manure at the rate of 1,000 kg DW/rai was added to all plots. Results showed that nutrient concentration in bird chili plant (shoot+leave) was N>K>Ca>Mg>P and decreased with increasing plant growth stage, but Ca concentration increased with increasing the plant growth stage. While total nutrient uptake in whole plant (shoot+leave+pod) during flowering stage to fruiting stage showed that N and K uptakes were not different but both were higher than Ca P and Mg uptakes. Total nutrient uptake was as followed: N 18.61, K 13.51, Ca 9.77, Mg 2.93 and P 1.77 kg N, K, Ca, Mg and P/ rai, respectively. We recommended that the fertilizer application at the rate of 10-10-12 kg N-P2 O5 -K2 O/rai + cow dung manure at the rate of 1,000 kg DW/rai was most appropriate for bird chili planting at Kanchanaburi province in clay loam soil which had 2.0% soil organic matter, and 13 and 115 mg/kg available P and exchangeable K, respectively. It resulted in the highest yield and maximized benefit for economic returns in the highest VCR 24. |
