A successful cultivation of any crop envisages sufficient knowledge about the nutritional requirement of plant. The response and requirement of various nutrients differ widely on the agro-climatic condition and management practices. A field study was conducted during rabi 2021-22 at the Instructional Farm of the Rajasthan College of Agriculture, Udaipur to study the effect of different levels of potassium and zinc on growth, productivity and quality of isabgol using randomized block design with 3 replications. The experiment consisted of 12 treatments comprising of fertilizers combinations viz., 40 kg ha-1 K2O + 30 kg ha-1 Zn, 40 kg ha-1 K2O + 25 kg ha-1 Zn, 40 kg ha-1 K2O + 20 kg ha-1 Zn, 30 kg ha-1 K2O + 30 kg ha-1 Zn, 30 kg ha-1 K2O + 25 kg ha-1 Zn, 30 kg ha-1 K2O + 20 kg ha-1 Zn, 20 kg ha-1 K2O + 30 kg ha-1 Zn, 20 kg ha-1 K2O + 25 kg ha-1 Zn, 20 kg ha-1 K2O + 20 kg ha-1 Zn, 40 kg ha-1 N + 20 kg ha-1 P2O5 + 20 kg ha-1 K2O, 40 kg ha-1 N + 20 kg ha-1 P2O5 and control. The results revealed that application of 30 kg ha-1 K2O + 20 kg ha-1 Zn resulted in significantly higher yield and yield attributes of isabgol.

Potassium and Zinc on Yield, Yield Attributes of Isabgol

From the present investigation, it is concluded that isabgol crop must be supplied with 30 kg ha-1 K2O + 20 kg ha-1 Zn along with 40 kg ha-1 N and 20 kg ha-1 P2O5 as soil application to get higher productivity and improved quality in prevailing agro-climatic conditions of zone IVa (Sub-Humid Southern Plain and Aravali Hills) of Rajasthan.
