Jatropha curcas is a promising alternative to meet the requirement of fossil
fuels and utilize the degraded lands. To harness the maximum production of Jatropha,
nutrient application, pruning and plant geometry optimization is essential. Six nutrient
doses, four pruning levels and five spacing treatments were imposed in a factorial randomised
block design. Pruning plant at one meter from ground level (P2) produced wider
canopy Nitrogen uptake was higher in N3 (50 – 50 – 50 kg ha-1of N, P2O5) and K2O and N4 (60 – 60 – 60 kg ha-1 of N, P2O5 and K2O) ranging from 666 to 808 mg plant-1
.Chlorophyll content was maximum (39.52 SPAD value) in N4 Collar diameter was significantly
higher(66.36mm) at 0.5 m pruning 4X4 m spacing. Biomass was higher at wider
spacing and lowest in closer spacing. Increased spacing resulted in higher canopy
diameter, leading to higher PAR interception.
