ABSTRACT: Alternatives to enhance the consensual low phosphorus (P) use efficiency of agriculture may include use of phosphate rock (PR) and plant species with unequal ability to get soil and rock P interplanted in cropping systems to allow plants with higher ability to facilitate access to P of plants with lower ability. This study investigated (i) the maize and three soil cover crops on their capacity to acquire P from PR and (ii) measured P acquisition of maize interplanted with the soil cover crop with the highest capacity to acquire P shown in (i). Experiments were carried out in a greenhouse, with plants grown in single and mixed cropping in pots containing a sandy, low?P soil amended with Monocalcium Phosphate (McP) or the Brazilian PR Itafós. Plant biomass production with PR, in relation to McP, was 83.7 % for buckwheat, 83.6 % for forage radish, 51.8 % for maize, and 0.3 % for pigeon pea. Buckwheat showed capacity of acquiring P from PR; nevertheless, it did not increase growth or P nutrition of maize interplanted in the soil amended with PR, showing no significant P facilitation. The soil amended with McP showed competition between the two plants in the pots. Maize had a greater growth in mixed than in single cropping and this occurred at the expenses of buckwheat. Despite the P mobilization potential of buckwheat, its simple interplanting with maize did not produce positive results. |
