Abstract:
Allelopathy is a phenomenon in which one plant growth affects the growth and establishment of other plants neighbouring to it. Allelopathy having special importance in our agro-forestry system. The decomposing residues of some allelopathic plants have been recorded to modify the rhizosphere, such that the germination and seedling growth of the neighbouring species are also affected. Although higher concentrations of phyto allelochemicals have detrimental effects on germination, seedling growth, and yield of crops, lower concentrations are reported to have stimulatory effects. The effects were concentration-dependent; an increase in concentration of extract was invariably associated with decrease in germination and seedling characteristics of the crops. Lower concentration of phytochemicals act as plant growth regulators and help in stress management. Different kinds of allelochemicals are reported to be released from plant's leaves. The study regarding the priming of plants extracts on wheat seed was carried out at Farm area of Department of Agronomy, Faculty of Agriculture, Gomal University year 2020-21. The trail was laid down in randomized complete block design with three replications. The seven treatments comprised of T1 (control), T2 (Conocarpus lancifolius Engl.), T3 (Acacia niltotica L.), T4 (Moringa oleifera Lam.), T5 (Dalbergia sisso Roxb.), T6 (Eucalyptus camaldulensis Dehnh.), and T7 (Pongamia pinnata L.) plant extracts applied @5 %(w/v) for seed priming of wheat seed variety AZRIC-Dera Ismail Khan. The treatment T4 (Moringa oleifera Lam.) and T5 (Delbergia sisso Roxb.) produced 7% and 3.56% higher yield than control (T1) while these treatments gave 15.1% higher yield than T6 (Eucalyptus camaldulensis Dehnh.).
