Question

Abu cultivated amaranthus along with plantain in his field. Name this method of cultivation

Answer 1

Answer:

Amaranthus Botanical Name- Amaranthus tricolour L. Family- Amaranthaceae Chromosome number -2n = 32 Origin - India

2. INTRODUCTION • The most common leafy vegetable grown during summer and rainy seasons in India. • Fits well in a crop rotation because of its very short duration nature and large yield of edible matter per unit area. • The estimation of the extent of its cultivation is not available. • Leafy types are usually grown in kitchen and market gardens.

3. BOTANY Habit Amaranthus is an annual herb with erect growth and scarce to profusely branching habit. Plant Annual herb, erect (trailing), mostly unarmed and rarely armed, scarce to produce branches, shallow to deep tap root system. Stem green to purple or with mixed shades of these two colours glabrous and succulent, leaf simple, alternate or opposite, exstipulate, entire obovate to lanceolate with acute tip green to purple or with shades of these two colors, purple coloration prominent in young leaves and fades away at maturity.

4. INFLORESCENCE  Inflorescence is terminal and axillary branched spikes differently coloured from green to deep purple to orange.  Flowers small, regular mostly unisexual, monoecious, pentamerous, membranaceous, often with persistent stamens 2-5, placed opposite to perianth parts, often some reduced to staminoides, filaments either free or united below, anther one or two to three styles and stigma, carpels 2-3, syncarpous, ovary superior with one cambylotropus ovule, styles single to 2 to 3 branched.

Answer 2

This method of crop cultivation is termed Intercropping

• Intercropping is an agricultural technique that entails planting or cultivating many crops on the same piece of land at the same time.
• It entails producing multiple types of crops in the same area at the same time.
• The logic behind this agricultural strategy is that diverse crops planted together are less likely to share insects and disease-causing agents, allowing for a higher yield than would be possible if all of the space was used by one crop.
• Planting more than one crop at the same time, with at least one of the crops planted in a row, is known as row intercropping.
• Strip intercropping is a more industrialised variation of row planting in which different crops are planted in alternate strips with rows large enough to allow for machine harvesting.
• Growing more than one crop at the same time without a distinguishing row pattern is known as mixed intercropping. Plants are naturally clumped together but in an ordered fashion.
• Relay intercropping is when two crops are planted on the same plot of land, with the second crop being planted after the first has flowered or completed its development, or shortly before the first crop is harvested.
• Because the crops take up a lot of space that would otherwise be available for weeds to grow, Intercropping help to suppress weeds.
• Growing two crops next to each other can be beneficial, especially if their interactions improve one or both plants' fitness.
• Plants that are prone to tipping over in the wind, for example, may benefit from the structural support of their companions.
• Light-sensitive plants may benefit from the shadow provided by some plants.
