Cropping System MCQ Quiz in తెలుగు - Objective Question with Answer for Cropping System - ముఫ్త్ [PDF] డౌన్‌లోడ్ కరెన్

In any cropping system Pulse crop is incorporated to replenish the N in field which was exhausted by the previous crop hence maintain soil fertility. One of the main advantages of the incorporating Pulse crop in a cropping system is that most pulses are short duration crop. For example, in Wheat-Rice Cropping system, one can take pulse crop in-between wheat and rice. With this we will have Wheat in Rabi, Rice in Kharif and Pulse in Zaid Season.

The correct answer is Micropropagation.

Key Points

Micropropagation

• Micropropagation is a method of plant propagation.
• It is done using extremely small pieces of plant tissue taken from a carefully chosen and prepared mother plant.
• It involves growing these plants under laboratory conditions to produce new plants.
• It is mainly used in commercial horticulture.

Advantages of Micropropagation:

• Plants produced through this method are clones, which help similarity in plants.
• The disease-free plants can be produced by this method of propagation.
• Rooted plantlets produced by this method of propagation save time for the grower, instead of seeds or cuttings.
• Thousands of plants can be produced at the same time.
• It is an ideal way of multiplying plants for those plants whose seeds can't be stored (recalcitrant seeds).

Additional Information

Embryogenesis	It is the process of initiating and developing an embryo from a zygote or a somatic cell.
Organogenesis	It is the phase of embryonic development that starts at the end of gastrulation and continues until birth.

The correct Answer is: Cassia siamea

Key Points

• Cassia siamea tree species is best suited for alley cropping.
• Alley cropping is an agroforestry system that involves planting rows of trees alongside crops.
• The trees provide shade, reduce erosion, and improve soil fertility, while the crops provide short-term income. 

Additional Information

• Eucalyptus tereticornis, also known as forest red gum or red gum, is a species of eucalyptus tree native to Australia and Papua New Guinea.
• It is commonly used for its wood, which is strong and durable, and for its essential oil, which has medicinal properties.
• Casuarina equisetifolia, also known as Australian pine or ironwood, is a species of evergreen tree native to Southeast Asia and Australia.
• It is commonly planted for erosion control, windbreaks, and as a source of firewood and timber.
• The tree's needles provide a nitrogen-rich mulch, which helps to improve soil fertility.
• Additionally, Casuarina equisetifolia is used in traditional medicine to treat various ailments.
• Ailanthus excelsa, also known as the tree of heaven or stink tree, is a species of deciduous tree native to China and Taiwan.
• It is commonly planted as an ornamental tree and for its wood, which is used in furniture making and paper production.
• The tree has medicinal properties and is used in traditional medicine to treat various ailments.

(a), (b) and (c) are the correct answers.

Ploughing, harrowing, and inter-culturing are the broad groups of tillage operations.

Key Points

Tillage: It is the mechanical manipulation of soil with tools and implements for obtaining conditions ideal for seed germination, seedling establishment, and growth of the crop.

Objectives of tillage:

• To create conditions in the soil suited for better growth of crops.
• To control weeds effectively.
• To make the soil capable of absorbing more rainwater.
• To mix up manure and fertilizers effectively in the soil.
• Providing adequate seed-soil contact permit water flow to seed and seedling roots.

Primary tillage:

• The operations are performed to open up any cultivable land to prepare a seedbed for growing crops known as primary tillage.
• Animal-drawn implements in primary tillage mostly include MB-plough.
• Tractor-drawn implements include MB-plough, disc plough, subsoil plough, chisel plough, and other similar implements.

Secondary tillage

• Lighter or finer operations performed on the soil after primary tillage is known as secondary tillage.
• Harrowing is to be done to a shallow depth to crush the clods and to uproot the remaining weeds and stubbles.
• Seedbed preparation and intercultural operations are done up to a depth of 15 cm.
• Secondary tillage implements: Disc harrow, spike tooth harrow, spring tooth harrow, acme harrow, etc.

The Correct Answer is Maize and Soyabean.

• Parallel Cropping is the cropping system in this cropping two crops are selected which have different growth habits and have a zero competition between each other and both of them express their full yield potential.
• Maize and Soyabean are compatible crops that can be grown along side each other on the same field and is an example of parallel cropping.

Types of Intercropping :- 

• Parallel Cropping:- Cultivation of such crops which have different natural habit and zero competition is called as parallel cropping. e.g. black gram/green gram + Maize. 
• Companion cropping:- System in which production of both intercrops is equal to that of its solid planting is called as companion cropping. e.g. Mustard/Potato/Onion + Sugarcane. 
• Mixed Intercropping:- Growing of two or more crops with no distinct row arrangement is called as mixed intercropping. 

The correct answer is Multiple cropping.

• The growing of two or more crops simultaneously on the same piece of land is known as mixed cropping.
• It is also known as multiple cropping.

Key Points

• This type of cropping leads to an improvement in the fertility of the soil.
• Hence it increases the crop yield.
• Mixed cropping is insurance against crop failure due to abnormal weather conditions.
• In intercropping, two or more crops are simultaneously grown with distinct row arrangements on the same field at the same time.
• Growing different crops on a piece of land in a pre-planned succession is called crop rotation.

The correct answer is Multistoried cropping.

• Practice of planting different crops of varying heights, rooting pattern and duration in the same field at the same time is known as Multistoried cropping. It is mostly practiced in orchards and plantation crops for maximum use of solar energy even under high planting density.
• Objective is to produce more in less space. It is also known as multi-layer or multi-tire cropping. It is one kind of intercropping.

a) Trap crop: A crop planted to attract insect pests from another crop, especially one in which the pests fail to survive or reproduce. E.g. Alfalfa planted with cotton.

b) Cover crop: Plants that are planted to cover the soil rather than for the purpose of being harvested. E.g. Oil-seed radishes planting along with cereal rye.

c) Nurse crop: Crops grown to protect the main crop from vagaries of nature and also to render support to the crop. Alfalfa planted with oats. Oats acting as nurse crop.

d) Inter crop: A crop grown among plants of a different kind. E.g. Planting of maize with beans and squash.

Ratooning is the practice in which stubbles of the original crop are left in field as it is to strike again after harvesting and raise another crop. It is followed in sugarcane production.

In Western Himalayan Region of India mostly Horticulture crops are grown. It has subtropical and temperate climatic conditions which are favorable for growing Horticultural crops which are grown in 16% of gross cropped area and which is higher than all India average of 4%
