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.

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.
