Study on performance of poplar clones in relation to soil condition and growth regulator application in nursery
The experiment was conducted to investigate the response of two types of soils (Sandy loam and Sandy clay loam) and foliar application of growth regulator i.e. Triacontanol at three levels (0ppm, 3ppm, 5ppm on nine poplar clones (PL-1 to PL-7, L-47/88 and L-48/89) at nursery stage, at experimental area of department of Forestry and Natural Resources, Punjab Agricultural University, Ludhiana. Various attributes like growth characteristics, physiological parameters and nutrient content in leaves were recorded at different interval of growth. The results of the study revealed that Triacontanol showed non-significant and soil types showed significant results for morphological characters viz. Plant height, collar diameter, no. of branches/plant, no. of leaves/plant and leaf area. Sandy clay loam soil showed good response than sandy loam soil for all morphological characters
