Growth of Crops (Sasyajataka)
On the authority of Sage Badarayana, this chapter outlines the planetary configurations (Yogas) that determine the success or failure of summer and autumnal crops, based on the Sun's entry into Vrischika (Scorpio) and Vrishabha (Taurus).
Summer Crops (Sun in Vrischika)
Prosperity Yogas
Benefics in Kendras from Sun or Sun aspected by/conjoined with strong benefics
→ Summer crops thrive splendidly
Sun in Vrischika, Jupiter and Moon in Kumbha/Simha (or vice versa)
→ Summer crops prosper
Venus and/or Mercury in 2nd/12th from Sun (Vrischika)
→ Summer corn grows well
Venus/Mercury in 2nd/12th + Jupiter aspecting Sun
→ Splendid growth
Sun (Vrischika) surrounded by Mercury & Venus (2nd/12th) + Jupiter & Moon in 7th
→ Excellent growth of corn
Venus in 11th, Moon in 4th, Mercury in 2nd from Sun (Vrischika)
→ Corn thrives well
Above Yoga + Jupiter in 10th
→ Great prosperity of cattle also
Adverse Yogas
Sun (Vrischika) surrounded by malefics (2nd & 12th)
→ Destroys crops
Malefic in 7th from Vrischika
→ Crops destroyed even if they grow well
Malefic in 2nd from Vrischika (unaspected by benefics)
→ Destroys first crops; subsequent ones bear fruit
Mars & Saturn in 7th and another Kendra from Sun
→ Destroys crops (unless aspected by benefics)
Autumnal & General Crops
Configurations
Sun in Mesha, Vrishabha, or Mithuna + Benefics (Merc, Jup, Ven)
Result
Summer corn fetches good price, free from pests, useful
Configurations
Sun in Dhanus, Makara, Kumbha + Benefics
Result
Autumnal crops flourish, fair price
Harvest Time Warning
If at harvest time, the Sun is aspected by or conjoined with two malefics, effects are contrary: Corn will be very costly, useless, and infested with pests (though period is good for sale).
