Evaluation of the relative root growth of Albizia procera seedlings grown under various treatment conditions in a nursery

Abstract

The comparison of the seedlings was done based on a combination of different pre-sowing treatments (soaking for 24 hours in (normal water (T1), Cooling boiled water (T2), Cow urine (T3), Beejamrutha (T4) and control (T5), container types (side perforated polythene bag of size (9 inche × 5 inch) (C1), root trainer of size 150 cc (C2) and 275 cc (C3) and growing mediums (Sand: Soil: Vermicompost (1:1:2) (M1), Sand: Soil: Vermicompost (1:2:1) (M2), Sand: Soil: FYM (1:1:2) (M3), Sand: Soil: FYM (1:2:1) (M4), Sand: FYM (1:1) (M5), Sand: vermicompost (1:1) (M6), Soil: FYM (1:1) (M7), Soil: vermicompost (1:1) (M8). The testing parameters consider some best growth of roots like root dry weight, total seedling dry weight, root: shoot ratio, root length, root thickness, number of secondary roots, percent fibrous roots, and nodule number. On the basis of the test report it was observed that the seedlings raised in the nursery were found to be suitable for overall quality seedling production of Albizia procera in the treatment combination T3C1M6, i.e. pre-sowing seed treatment T3 (seeds soaked in cow urine for 24 hours), polybag C1 of size (9 inch x 5 inch), filled with growing medium Sand + Vermicompost (1:1) (M6).
