Abstract
A concept on crop removal evaluation is presently applied for optimum nutrient management of crops.
The objective of this work was to investigate the nutrient loss caused by the fruit of ‘Nom Sod’ jujube.
The nutrients in four fruit classes (jumbo, A, B, and C) were determined to be nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and boron (B). The 15 sampled fruits in each class were harvested from the five trees of a six-year-old jujube planted in Banphon, Kham Muang district, Kalasin province, Thailand, during January-March 2019. Also, the yield tree‑1 was recorded during the same period.
The result showed that the concentrations of N, P, K and Ca in all fruit classes were not significant.
The range of nutrient concentrations was 1.07-1.40% N, 0.17-0.24% P, 1.35-1.53% K and 0.59-0.79% Ca.
However, B in the jumbo class exhibited the lowest value (7.27 mg kg‑1, P<0.05), while B in other fruit classes ranged from 15.42 to 17.24 mg kg‑1. Then, the evaluated nutrient content loss per tree with 140 kg of fruit was 226.28 g N, 34.44 g P, 255.97 g K, 125.62 g Ca and 298.29 mg B.
