International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &<br />

Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad<br />

practice with traditional farming practices, T2: Bhairabi with improved package <strong>of</strong> practices,<br />

T3: Arjuna with improved package <strong>of</strong> practices and T4: Kalua with improved package <strong>of</strong><br />

practices) and ten replications taking each farmer as a separate entity. The allocated land area<br />

to each farmer was equally split into four treatments to fit all the varieties. Finger millet<br />

nursery was done with seed rate <strong>of</strong> 10 kg/ha. Transplanting <strong>of</strong> 21 days old seedlings with<br />

spacing <strong>of</strong> 20 cm × 10 cm was done. Application <strong>of</strong> 100% RDF (40:20:20 kg N-P 2O 5-<br />

K2O/ha) and timely weeding and need-based plant protection measures were carried out.<br />

Basal application <strong>of</strong> half <strong>of</strong> nitrogen, total phosphorus and potash were applied over the main<br />

field just before transplanting. Remaining half <strong>of</strong> nitrogen was applied 21 DAT depending on<br />

soil moisture availability.<br />

Results<br />

Perusal data from the figure 1 revealed that Cultivation <strong>of</strong> Arjuna with improved package <strong>of</strong><br />

practices resulted in significantly higher number <strong>of</strong> fingers/panicle (10.2) and grain yield<br />

(18.27 q/ha) than farmers’ practice <strong>of</strong> growing local varieties (4.8 and 10.04 q/ha,<br />

respectively). This is closely followed by cultivation <strong>of</strong> Kalua (7.8 and 16.02 q/ha,<br />

respectively) and Bhairabi (6.2 and13.22 q/ha, respectively).<br />

Conclusion<br />

Grain yield <strong>of</strong> high yielding ragi varieties<br />

(T1: Farmers’ practice T2: Bhairabi T3: Arjuna T4:Kalua)<br />

From the field experiment, it was concluded that Cultivation <strong>of</strong> Arjuna with improved<br />

package <strong>of</strong> practices performs better than cultivation <strong>of</strong> farmers’ local varieties in Ganjam<br />

district <strong>of</strong> Odisha. Thus, existing varieties <strong>of</strong> local ragi varieties may be replaced with high<br />

yielding Arjuna variety due to its superior agronomic performance.<br />

Climate resilient agriculture for risk mitigation<br />
