Brihat Samhita
स्वातौ निशांशे प्रथमे अभिवृष्टे सस्यानि सर्वाण्युपयान्ति वृद्धिम् । भागे द्वितीये तिलमुद्गमाषा ग्रैष्मं तृतीये अस्ति न शारदानि ॥ २५-०२ ॥
Dividing both the day and night of the Svāti Yoga day each into three equal parts, if at night there should be a fall of rain during the first division, all the crops will flourish; if during the second division, gingelly, green gram and black gram will thrive and if during the third division, the crops of Grīṣma will thrive and those of Śarad will perish.
