A field experiment was conducted to study the effects of varying levels of plant geometry, fertilizer and cycocel on yield, quality and nutrient uptake of niger (Guizotia abyssinica Cass.) under rainfed conditions at Main Agricultural Research Station, Dharwad during Kharif 2014. The experiment was laid out in randomized completely block design (factorial concept) with 18 treatment combinations with single control and three replications. The treatment consisted of three planting geometries (30 x 10cm, 45 x 10cm and 60 x 10cm), three fertilizer levels (75% RDF, 100% RDF and 125% RDF) and two doses of cycocel spray (500 ppm and 1000 ppm at 30 days after sowing). The results showed that the treatment combination of planting geometry of 45 x 10cm with 125% RDF and 1000 ppm cycocel spray recorded significantly higher total dry matter production (57 g plant-1), N uptake (37.3 kg ha-1), P uptake (9.2 kg ha-1), K uptake (10.8 kg ha-1), seed yield (726 kg ha-1) and stalk yield (2606 kg ha-1) as compared to other treatment combinations. There was 20.3% increase in grain yield, 19.0 % increase in stalk yield, 11.5% increase in N uptake, 8.0% increase in P uptake and 9.8% increase in K uptake by niger over control.
