Abstract:
A field experiment was carried out during Rabi 2021-2022 at Organic Farming Unit of Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment was laid out in factorial randomized block design with three replications and assigning sixteen treatment combinations consisting of two factors and both were at four levels first factor was different doses of Lantana camara biochar i.e. control and different levels of Lantana camara biochar (1.5 t ha^-1, 2.5 t ha^-1, 3.5 t ha^-1) and second factor was different time of application of lantana camara biochar (at sowing, at branching, at pod formation, 50% at sowing + 50% at branching). Results revealed that application of 3.5 t ha^-1 Lantana camara biochar gave higher seed yield (1436 kg ha^-1), haulm yield (3523 kg ha^-1) and biological yield (4959 kg ha^-1) as compared to control, 1.5 t ha^-1, and application of 3.5 t ha^-1 Lantana camara biochar and application of 2.5 t ha^-1 Lantana camara biochar perceived to be par with each other. Application of Lantana camara biochar in two split does i.e. 50% at sowing + 50% at branching resulted in higher seed yield (1386), haulm yield (3334 kg ha^-1) and biological yield (4720 kg ha^-1) as compared to application of Lantana camara biochar at time of sowing, at branching and pod formation stage, respectively.
