New Seeds: High Yielding Variety (HYV)

What does the term high yielding variety (HYV) seeds mean?

• Seeds used only for garden flowers

• Seeds that are cheapest in the market

• Seeds saved by farmers every harvest

• Seeds developed for higher crop output

Earlier, why didn’t saved traditional seeds always give good harvests?

• They required no water to germinate

• They always grew into different plants

• They were illegal for farmers to plant

• They sometimes produced lower crop yields

A farmer wants to increase the amount of grain harvested from each field. Which seed choice best matches this goal?

• Planting seeds later than the season

• Planting high yielding variety seeds

• Planting only last year’s saved seeds

• Planting seeds randomly without care

Read the poster that says “Buy high yielding seeds.” What is the most likely reason a shop advertises these seeds to farmers?

• They are older traditional seed types

• They make fields look more colorful

• They grow only in small home pots

• They help raise production per crop

Which method did farmers commonly use in the past to lift water from lower levels?

• Sprinkler pipelines

• Water wheel devices

• Electric tube wells

• Drip emitters

Why did many farmers shift from traditional water drawing to tube wells and canals?

• Rainfall stopped completely

• Wells were banned by law

• Rivers became shorter

• HYV seeds need more water

Which system delivers water directly to plant roots through small outlets, reducing waste?

• Centre pivot sprinkler

• Drip irrigation system

• Canal flood system

• Water wheel lifting

Water naturally moves from a higher level to a lower level. Which challenge does this create for irrigation?

• HYV seeds stop absorbing water

• Sprinklers cannot rotate properly

• Canals always overflow fields

• Lifting water upward is difficult

A farmer has a long rectangular field and wants even watering with rotating arms on a moving frame. Which method best fits this plan?

• Traditional furrow flow

• Water wheel lifting

• Terraced hillside steps

• Centre pivot irrigation

You are planning a farm on a steep hillside. Which irrigation approach helps slow water flow and prevent soil from washing away?

• Deep tube well only

• Centre pivot spraying

• Open canal flooding

• Terraced irrigation steps
