(2021 and 2022) at the Agricultural Research Station, Kampasagar, Nalgonda district,<br />
on sandy clay loam soils using a split-plot design with three main plots and three sub-<br />
plots, replicated thrice. Root parameters such as root volume and root-to-shoot ratio<br />
showed significant variation among establishment methods, with dry direct seeded<br />
rice (M 1 ) recording numerically higher values. However, yield-attributing traits like<br />
number of panicles m⁻² (285.5), panicle length (27.3 cm), panicle weight (4.69 g),<br />
number of spikelets panicle⁻¹ (196.7), filled grains panicle⁻¹ (189.8) and test weight<br />
(26.6 g) were significantly influenced by establishment methods, with wet direct<br />
seeded rice (M 2 ) performing better, on par with manual transplanting (M 3 ) and<br />
superior to dry seeding. Irrigation treatments and interactions had no significant<br />
effect on root traits and yield parameters, although alternate wetting and drying<br />
(AWDI) and continuous submergence performed better than saturation irrigation. A<br />

semi-arid conditions, highlighting the potential of wet direct seeding and AWDI to<br />
improve rice productivity while optimizing water use.</p>
