The correct answer is Cucumber. Explanation & Key Takeaways: • Cucumber is an example of zaid crop. • Crops that are being raised throughout the year due to artificial irrigation are Zaid crops. • Zaid crops are grown between Kharif and Rabi Seasons, i.e., between March to June. • They require warm, dry weather as a vital growth period and a longer day length for flowering. • Zaid crop is also known as a gap-filler between two chief crops, Kharif and Rabi. • Examples: Cucumber, Pumpkin, Bitter gourd, Watermelon, Muskmelon, Groundnut, Pulses, etc. • The Time Of Sowing For Zaid Crops Changes from Place To Place Depending On The Rainy Season. So the Sowing Period Of The Zaid Crops Is Not Fixed, It Changes All Over India.
