Phosphorus (P) is one of the essential nutrients needed by plants in large amount. However response of fruit crops to phosphorus application may vary depending on soil and climatic conditions of the area. Hence this study was conceptualized to evaluate the growth yield and fruit quality of MD-2 pineapple in response to varying rates of P under Adtuyon clay soil in Bukidnon Philippines. The experiment was laid out in a randomized complete block design (RCBD) with five amounts (0 84 127 169 and 211 kg ha- respectively) of P as treatments with three replications. Results revealed that MD-2 pineapple growth was significantly influenced by P application. However highest dose (211 kg ha-) of P in Adtuyon clay soil did not provoked significant P uptake of MD-2 pineapple. Instead P uptake declined beyond 169 kg P ha- application. Zn uptake of pineapple declined also as P applied in soil was beyond 169 kg P ha-. Unpredictably MD-2 pineapple plants starved with P still produced fruits (mean fruit mass of 1.28 kg) with a yield of 76.80 tons ha- however it could not be denied that higher doses of P (169 kg ha-) improved the fruit mass (1.42 kg) as well as yield (96.92 tons ha-) of MD-2 pineapple. Fruit physicochemical properties of MD-2 pineapple was not dependent on the amount of P applied in the soil. In general 169 kg P ha- was found as the optimal amount of P for MD-2 pineapple production in Adtuyon clay soil.

Abstract

Phosphorus (P) is one of the essential nutrients needed by plants in large amount. However response of fruit crops to phosphorus application may vary depending on soil and climatic conditions of the area. Hence this study was conceptualized to evaluate the growth yield and fruit quality of MD-2 pineapple in response to varying rates of P under Adtuyon clay soil in Bukidnon Philippines. The experiment was laid out in a randomized complete block design (RCBD) with five amounts (0 84 127 169 and 211 kg ha- respectively) of P as treatments with three replications. Results revealed that MD-2 pineapple growth was significantly influenced by P application. However highest dose (211 kg ha-) of P in Adtuyon clay soil did not provoked significant P uptake of MD-2 pineapple. Instead P uptake declined beyond 169 kg P ha- application. Zn uptake of pineapple declined also as P applied in soil was beyond 169 kg P ha-. Unpredictably MD-2 pineapple plants starved with P still produced fruits (mean fruit mass of 1.28 kg) with a yield of 76.80 tons ha- however it could not be denied that higher doses of P (169 kg ha-) improved the fruit mass (1.42 kg) as well as yield (96.92 tons ha-) of MD-2 pineapple. Fruit physicochemical properties of MD-2 pineapple was not dependent on the amount of P applied in the soil. In general 169 kg P ha- was found as the optimal amount of P for MD-2 pineapple production in Adtuyon clay soil.
