Agniveshyagrihyasutra 2.5.12

Now we shall explain the sowing of seeds.

Under Rohiṇī, Tiṣya, the two Viśākhās, the Maghās, Śravaṇā, Revatī, [or under the asterism] of Mitra and Varuṇa, of the Maruts, or one of the Uttaras—having taken seeds under one [of these] asterisms, having given [a preliminary rite], he performs the preliminary consecration.

Under one of these asterisms, having gone to the field, having worshipped in the eastern quarter with perfumes and the like, having strewn it with leaves of the Siris tree, having anointed himself with the remainder of the perfume, and having given perfume and the like to the ploughman, he should sow the seeds with this section: "The plants that were born..."

Then, before calling [for the harvest], having cooked a strengthening caru, having made [Brahmins] declare an auspicious day, having sprinkled [himself] with water with the three verses: "Waters indeed are refreshing...", with the four verses: "Golden of color, pure, purifying...", and with this section: "The purifying [Soma], the heavenly light...", he then gives a rice-ball with: "O Lord of the field, yield for us a honeyed wave, as a cow yields milk!

Dripping honey, like well-purified ghee—may the lords of truth be gracious to us!" Then on the south-east, then on the south-west, then on the north-east, then on the north-west, then in the center, he performs the reaping as prescribed.

With that grain, he subsequently performs the first-fruits sacrifice.
