Abstract:
The use of bio-stimulants is gaining popularity in today’s agriculture due to their ability to increase yield and quality of crops without harming the environment. To ascertain the above facts, research experiments were conducted during Rabi season 2021 to evaluate the response of fodder oat to various bio-stimulants applied as foliar spray. The first pot study was conducted for dose optimization under completely randomize design using foliar applied bio-stimulants viz. Moringa leaf extract at ratio of 1:10, 1:20, 1:30, 1:40, 1:50, Sea weed extract at 1%, 2%, 3%, 4%, 5%, Thiourea at 100 ppm, 200 ppm, 300 ppm, 400 ppm, 500 ppm and Chitosan at 25 ppm, 50 ppm, 100 ppm, 125 ppm, 150 ppm applied at tillering and booting growth stages of fodder oat. The results revealed that moringa leaf extracts, Sea weed extract, Thiourea and Chitosan at 1:40, 2%, 400ppm and 100 ppm respectively increased the vegetative growth and quality of oat than other concentrations. Based on the results of dose estimation experiment, a field experiment was conducted at Crops Sciences Institute, NARC Islamabad, Pakistan in 2020-21. Thetreatments comprised foliage application of Sea weed extract and Chitosan applied at 2% and 100 ppm respectively as single dose and combined. The experiment was conducted in Randomize Complete Block Design with three replications in factorial arrangement. Two Oat varieties viz. NARC oat and PARC oat were assigned to the main plots while bio-stimulants were assigned to the subplots. Bio-stimulants were applied at tillering (45 DAS) and booting 75 (DAS) growth stages. Data regarding agronomic, physiological and quality traits of oat was recorded. The results of the fieldexperiment revealed significant influence of Sea weed extract and Chitosan on growth, yield and quality traits of fodder oat than control. Therefore, it was inferred from the above research experimentation that use of bio-stimulants could be a good option to increase the fodder yield and quality of fodder oat to overcome fodder shortages during the lean period in the study area and reduce cost of fodder oat production.
