Abstract:
A field experiment entitled “Response of Isabgol (Plantago ovata Forsk.) to hydrogel levels under different irrigation schedule” was conducted at Instructional Farm of Agronomy, Department of Agronomy, Rajasthan College of Agriculture, MPUAT, Udaipur during the rabi season of 2018-19 and 2019-20 to study the effect of hydrogel levels under different irrigation schedules. The soil of experimental field was clay loam in texture, slightly alkaline in reaction (pH 8.1), low in available nitrogen (270.60 to 271.30 kg ha-1), medium in available phosphorus (18.07 to 18.90 kg ha-1) and high in available potassium status (312.70 to 315.40 kg ha-1). The experimental design split plot design was used comprises main plot factor four irrigation schedule viz., IW-CPE ratio 0.20, 0.30, 0.40 and 0.50 sub plot factor hydrogel levels which also having four levels viz., control, 2.5, 5.0 and 7.5 kg ha-1 combined having 16 treatment combinations, which were replicated four time. Isabgol crop variety “Udaipur Isabgol- 89” was used as test crop. The results revealed that application of irrigation at IW-CPE ratio in Isabgol crop produced significantly increased nutrient uptake and total uptake. The crop irrigated at IW-CPE ratio of 0.50 accumulated highest quantum of nutrient in seed, straw thereby total accumulation which was found at par with IW-CPE ratio of 0.40 and both these ratio significantly increased total nitrogen uptake by 15.24, 25.61, phosphorus uptake by 11.96, 20.78 and potassium uptake by 10.46, 19.17 per cent, respectively over IW-CPE ratio of 0.30 and 0.20. Application of hydrogel up to 5.0 kg ha-1 significantly increased nitrogen, phosphorus and potassium uptake by seed and straw thereby total accumulation over application of 2.5 kg ha-1 and control. The magnitude of increase in total nitrogen, phosphorus and potassium uptake was 8.63, 7.68, 5.61 and 16.01, 14.95, 11.22 per cent, respectively. Further increase in hydrogel level to 7.5 kg ha-1 though positively influenced uptake of nutrients but failed to record statistical significance over 5.0 kg hydrogel ha-1.
