Abstract:
Seed dormancy in wheat is observed in saline or late sown condition in Pakistan. Some phyto extract of trees having gibrillic acid and cytokinin which promote germination. Allelopathic trees present in our agro-forestry system having significance importance in this regard. Allelopathic compounds releases from decaying of tree's residue in lower concentration not only help in germination but also improve the growth, development and maturity under abiotic stress condition. Although higher concentrations of phytoallelochemicals have detrimental effects on germination, seedling growth, and yield of crops. These 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 (Dalbergia 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.). Hence T4 (Moringa Oleifera Lam.) and T5 (Dalbergia sisso Roxb.) may be used as seed priming substances to enhance germination and attain higher grain yield. Planting of Conocarpus lancifolius Engl. and Eucalyptus camaldulensis Dehnh should be avoid near the wheat crop due to inhibitory effect on wheat growth and grain yield.
