Influence of seed priming techniques on grain yield in combination with different seed rates of wheat

Abstract
To reach a good plant stand, the life cycle of plants is faced with different critical stages such as uneven seed germination, poor and early seedling growth which ultimately results in low crop yield. It is well known that seed priming enhances germination, reduces seedling emergence time, and improves yield and yield contributing characteristics of plants. A 2-year study evaluated the effect of different seed-priming techniques on the performance of seed rates on short (Israr-IV) and long (Gomal-VIII) duration, experiments were conducted at the agronomic research site of Gomal University, Dera Ismail Khan, Pakistan, on wheat varieties during winter season 2021 and 2022. The research aimed to assess the influence of seed priming on wheat. In the first experiment, various priming techniques viz. T1: Control, T2: Tap water (primed for 2 hours), T3: Sewage water (primed for 3 hours), T4: Farmyard manure (primed for 6 hours), T5: Compost manure (primed for 8 hours), T6: Poultry manure (primed for 8 hours), T7: Press mud (primed for 12 hours) and T8: Sodium chloride were studied. Seed priming resulted in earlier and more uniform crop emergence and improved yield-related traits compared with untreated seeds. It was found that the interaction of farmyard manure priming with Israr-4 and Gomal-8 produced the tallest plants, produced maximum tillers (m-2), longer spikes, more seeds per spike-1, and final grain yield. Farmyard manure priming is recommended for wheat crops. One of the important aspects for quality grain production is rapid emergence and good seedling establishment in the field. Therefore, quick and uniform field emergence is essential to achieve high yield in annual crops.
