Abstract:
A field experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner in Jaipur district of Rajasthan during kharif season of 2016 on loamy sand soil. The experiment consisted of four levels each of N (0, 20, 40 and 60 kg/ha) and potassium (0, 10, 20 and 30 kg K₂O/ha). The total 16 treatment combinations were tested in randomized block design with three replication. Results indicated that progressive increase in level of nitrogen up to 40 kg/ha significantly increased physiological parameters (leaf area index & chlorophyll content), yield attributes (number of capsules/plant, seeds/capsule and test weight) and total nutrient uptake (N, P & K) in sesame. Further increase in nitrogen level to 60 kg/ha could not enhance the above parameters significantly. Results further revealed that progressive increase in level of potassium up to 20 kg/ha significantly increased above mentioned parameters of sesame over 10 kg K₂O/ha and control. The above treatment remained at par with 30 kg K₂O/ha.
