Background: Prominence and demand for sesame is high, however, its production remains quite low. Scarcity of labour is one of the constraints to carry out the key operations in time, wherein delayed operations result in low productivity. The newly evolved non-branching type sesame is amenable for farm mechanization. Optimizing the crop geometry is a pre-requisite to step further for mechanizing the newly evolved monostem sesame cultivation. Keeping these aspects in view, field evaluations were conducted to evaluate the yield potential of non-branching monostem sesame.

Methods: The newly evolved non branching monostem sesame VRI was evaluated with eight set of treatments viz., T1 - 30 x 30 cm, T2 - 30 x 15 cm, T3 - 30 x 10 cm, T4 - 20 x 20 cm, T5 - 20 x 15 cm, T6 - 20 x 10 cm, T7 - 30 x 20 x 10 cm in paired row, T8- 30 x 15 x 10 cm in paired row during two seasons viz., Summer 2021 and Summer 2022. The experiment was laid out in three replications following randomized block design.

Results: Higher plant height at harvest (88.1 cm), number of nodes per plant (14.1) and internode length (5.38 cm) were noted at a wider spacing of 30 x 30 cm. However, a higher seed yield of 770 kg/ha was recorded at a square geometry of 20 x 20 cm.

Conclusion: Based on the two consecutive years of field experiment it is ascertained that the crop geometry at a spacing of 20 x 20 cm is ascertained to be optimum in recording higher productivity of monostem sesame VRI 5.
