Abstract

Seedlings on raised beds were subjected to a variety of ischolar_main culturing and fertilizer treatments. Seedlings parameters were recorded at the time of outplanting. The undercutting and wrenching treatments produced shorter and thin stemmed seedlings with reduced shoot, seedling and total ischolar_main dry weight in comparison to the untreated seedlings. The number, length and dry weight of lateral ischolar_mains were stimulated in treated seedlings. The application of N and P fertilizers individually and in conjunction with undercutting and wrenching also showed significant improvement in growth and biomass characters. The application of 80 kg N/ha and 30 kg P₂O₅/ha were considered appropriate for better performance of seedlings. The seedlings were better conditioned to withstand outplanting stress and showed improved survival over the respective control.

Abstract

Conditioning treatments viz. undercutting and wrenching significantly influenced all the studied ischolar_main biochemical parameters (proline content, peroxidase activity, total sugars, starch and carbohydrates). Values exhibited an increasing trend with decrease in undercutting depth and increase in wrenching frequency. Application of ammonium nitrate and single super phosphate as nitrogen and phosphorus sources of fertilization, respectively failed to show much effect on these parameters. The increase in stress imposed by undercutting depth × wrenching frequency interaction also manifested effect on these physiological parameters. In general, the nutrients N, P, K, Ca, and Mg content in ischolar_mains increased with increase in stress level. The fertilizer application following undercutting and wrenching treatments also influenced the ischolar_main nutrient concentration significantly.
