Macro-nutrient uptake by cocoa seedlings (Theobroma cacao L.) as influenced by clone and soil-applied nitrogen levels

Popis výsledku v původním jazyce

Clonal cocoa (Theobroma cacao) seedlings are used in national rejuvenation programs for cocoa farmers in Indonesia. However, the effects of nitrogen fertilization in clonal cocoa are poorly understood. Therefore, we evaluated the effect of clones and nitrogen addition to the soil on macronutrient concentration and uptake by young seedlings. Ten different clonal cocoa seedlings were grown for five months in pots and arranged in a nursery of the Indonesian Coffee and Cocoa Research Institute (ICCRI), Jember, Indonesia. Each clone received two N treatments (0 and 2,3 g N applied at the beginning of the experiment). A factorial randomized block design was used with four replications. Plant tissue macronutrient concentration and uptake were investigated. We found a significant (P 0,05) clonal effect on P, K, and Mg concentration in the shoots. Clones also significantly (P0,05) affected root P and Mg uptake as well as shoot Mg uptake. N treatments resulted in a significant (P0,001) increase in N and Ca con
