Fig. 1.

Impact of manipulating planting geometries on Nilaparvata lugens incidence during 2018 and 2019. Means sharing similar letters are not significantly different at P > 0.05.

Fig. 2.

Impact of manipulating planting geometries on agronomic parameters of Basmati-515 during 2018 and 2019. Bars without lettering shows non-significant (P > 0.05) difference among the treatments. Means sharing similar letter are also not significant at P > 0.05.

Fig. 3.

Impact of manipulating planting geometries on yield of Basmati-515 during 2018 and 2019. Means sharing similar letters are not significantly different at P > 0.05.
