International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad to efficient use of sunlight and increased light interception leads to thick and stronger stalks and healthy development of cobs. The results revealed that, farmers realized an additional yield of 30 q/ha in paired row method when compared to traditional cultivation method. Further, an additional income achieved from paired row method of planting was Rs.61,467.5/- /ha. Besides this, the paired row method of planting recorded higher gross returns, net returns and B:C ratio when compared to traditional cultivation method. T4a-56P-1567 Improving Productivity of Taramira (Eruca sativa Mill.) Under Conserved Soil Moisture in Arid Environments M. Patidar, R. Saranya and Anil Patidar ICAR- CAZRI, Reginal Research Station, Jaisalmer, Rajasthan 342 003 India The availability of soil moisture is the most important factor for growing crops in arid conditions therefore the choice of crops is limited due to the low and erratic nature of rainfall (Moharana et al. 2016). Sometimes the rain receives at the end of the Kharif season is not utilized by the Kharif crops and is also not sufficient for growing subsequent long duration rabi crops but the conserved soil moisture can be utilized for short duration rabi crops. Taramira (Eruca sativa Mill.) is short duration crop, particularly suitable for north-western Rajasthan, and can be grown in the early rabi season utilizing the conserved soil moisture (Mundiyara and Jakhar, 2017). Further, the time of sowing needs to be adjusted for improving productivity. With this, the experiment was conducted to study the utilisation of conserved soil moisture and the effect of sowing time on its productivity. Methodology The experiment was conducted during rabi 2021-22 involving three different dates (Last week of September (S1), October (S2), and November (S3)). T1 (last week of September)- utilized conserved soil moisture of (103 mm rainfall received in that month) + one irrigation at grain filling stage, T2 (sown at last week of October)- 1 st irrigation after sowing+ 2 nd irrigation at grain filling stage; T3(sown at last week of November)- 1 st irrigation after sowing+ 2 nd irrigation at grain filling stage. The climate of the area is hyper-arid, characterized by exceptionally hot dry summers, and cold dry winters. The soil is coarse loamy sand, low in organic carbon and available nitrogen, and medium in available phosphorus with pH 8.1. The rainfall during the year 2021 is 338 mm. Taramira variety RTM -13 was sown in the plot size of 5.5 m × 4.5m with 30 × 10 cm spacing using a seed rate of 5 kg/ha. The treatments were replicated four times randomly. 689 | Page Resource conservation and rainfed agriculture
International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Observations were recorded for plant height, primary branches, pod per branch, pod length, and seed yield. Results The maximum plant height and pod per branch were recorded in S1 (91.58 cm; 34.92) followed by S2 (87.75 cm; 23.92) and S3 (82.50 cm; 25.50). There was no significant difference in number of primary branches and pod length. The seed yield was highest in S1 (950 kg/ha) followed by S2 (837.5 kg/ha) and S3 (675 kg/ha). The increase in seed yield due to the first sowing was by 13.4 and 40.8 % over the second and third sowing respectively. The higher seed yield in first sowing (S1) was due to better root development and plant growth as result of more availability of soil moisture. Its efficient root system helped in extracting moisture from deeper layers of soil. Conclusion The result indicates that the crop sown in the last week of September, which utilised the conserved soil moisture, gave a better seed yield than other dates of sowing with two irrigations. During periods of severe drought and late monsoon, taramira is the only alternative crop left for arid region farmers to sustain their livelihood.
