Macro- and micronutrient uptake by nodulating and non-nodulating peanut lines uri icon

abstract

  • Amounts of N, P, K, Ca, Mg, Zn, Fe, and Mn absorbed by a nodulating and a non-nodulating (Non-nod) peanut genotype at two nitrogen fertilizer levels (nil and 200 kg N ha?1) were determined in a field experiment. The amounts of nutrient elements in the plant parts were greatest for N, followed by K, Ca, Mg, P, Fe, Mn, and Zn in descending order. Although there were differences in the uptake of other nutrients, the major difference between Non-nod and nodulating genotypes was in nitrogen indicating the poor yield of the Non-nod line due to its inability to acquire N
