ABSTRACT
One of the best attribute pertaining to Jatropha is its ability to grow in low fertile marginal soil as envisaged in this experiment. The present study deals with agronomic trials with the aim to find out best agronomy practices with respect to irrigation and fertilizer for optimizing Jatropha seed production. Plots were laid out in split-plot design and treated with urea 12 gm/plant, MoP 20 gm/plant, DAP 20gm/plant, Sulphur 5gm/plant, Azotobactor 2.78gm/plant, Trichoderma 2.78gm/plant, PSB 2.78gm/plant, either alone or in combination. Three times fertilizer application added with Sulphur was found the best treatment for higher production. The maximum height, diameter, branches, crown length & breadth observed in Jatropha plant due to three times application of fertilizer (Urea, DAP, MoP) with sulphur. Fertilizer application rendered great role in the seed production of Jatropha.

hoots plant-1 (8.03), number of leaves plant-1 (21.0), leaf area (724 cm2), leaf area index (0.60), total dry matter plant-1 (7.30 g) over weedy check (48.67 cm, 4.33, 10.33, 400 cm2, 0.33 and 4.84 g, respectively). Application of Fenoxaprop–p-ethyl 54 gm a.i. ha-1 as early post emergent at 20 DAP recorded significantly higher number of tubers plant-1 (4.30), tuber weight plant-1 (250.50 g) and tuber yield (19.77 t ha-1) which was on par with Quizalofop–p-ethyl (4.07, 247.37 g and 18.93 t ha-1, respectively) except weed free check.
