Linear forecasting nutrient uptake model for teak (Tectona grandis) in early developmental stages (seedling stages) under fertigation system

Teak (Tectona grandis) is a valuable timber yielding species in the world due to its exemplary quality and market value. Though teak plantations twirls natively, countries like India are mostly depending on total import of teak for domestic utility. Thus the need to adopt a precised planting technology for Teak productivity enhancement is highly relevent. In this context, a field experiment was conducted with nitrogen, phosphorus & pottasium (NPK) fertiliser under drip fertigation system to study the early (seedling) response of teak in relation to nutrient uptake and growth. All yield prediction models in teak were related to growth and age, but research towards yield related to nutrient is least available. The model developed helps to conclude that, in the current study, height, basal diameter and volume index is predominantly a function of phosphorus and potassium uptake during initial growth phase (4 months after treatment), while 8 months after treatment, basal diameter and volume index were expressed as a function of nitrogen and phosphorus uptake. Hence the model helps to optimise nutrient use efficiency (NUE) of teak at different growth stages with good growth rate.

Abstract

Teak (Tectona grandis) is a valuable timber yielding species in the world due to its exemplary quality and market value. Though teak plantations twirls natively, countries like India are mostly depending on total import of teak for domestic utility. Thus the need to adopt a precised planting technology for Teak productivity enhancement is highly relevent. In this context, a field experiment was conducted with nitrogen, phosphorus & pottasium (NPK) fertiliser under drip fertigation system to study the early (seedling) response of teak in relation to nutrient uptake and growth. All yield prediction models in teak were related to growth and age, but research towards yield related to nutrient is least available. The model developed helps to conclude that, in the current study, height, basal diameter and volume index is predominantly a function of phosphorus and potassium uptake during initial growth phase (4 months after treatment), while 8 months after treatment, basal diameter and volume index were expressed as a function of nitrogen and phosphorus uptake. Hence the model helps to optimise nutrient use efficiency (NUE) of teak at different growth stages with good growth rate.
