Abstract:
This experiment was conducted to study the effect of apical pinching and foliar spray of potassium nitrate on the five year old plant at Nagri field, 7 km away from the Institute of Forest Productivity, Ranchi, Jharkhand during 2016-2017. Nine treatments (three doses of potassium nitrate combined with each of three doses of pinching off treatments) with two replications in spit-plot design experiment was used. The maximum fruits and seeds number per plant (398.00 fruits/plant and 860.75 seeds/plant) was found in Treatment-6 (Pinching of 10 cm with foliar spray of 2% potassium nitrate) and least (192.00 fruits/plant and 359.25 seeds/plant) in Treatment-8 (Pinching of 5 cm with foliar spray of 4% potassium nitrate). The maximum oil content (56.19%) was reported from the treatment-9 (Pinching of 10 cm with foliar spray of 4% potassium nitrate) and least (37.81%) was found in the Treatment-4 (only foliar spray of 4% potassium nitrate). Higher concentration of potassium nitrate increases the oil content and decreases the yield and lower concentration increases the yield with constant oil content.
