What is meant by ratoon cropping?
Ratoon cropping is defined as the cultivation of the crop growth after cane harvest, although not necessarily for grain (Francis 1989). This is essentially sequential cropping to give crop intensification in the time dimension and there is no intercrop competition.
What are the advantages of ratoon cropping?
Sugarcane is an important sugar crop and it can be subjected to ratooning for several years. The advantages of ratooning include quality improvement, efficiency enhancement, and reduced costs and energy use.
Can rice be Ratooned?
With good crop management, ratoon rice gives a yield equivalent to 60% that of the main crop but with a 50% reduction in resources and labor input. Moreover, rice ratooning improves the grain quality, increases the profits for farmers, and decreases greenhouse gas emissions.
What are the two disadvantages of ratoon cropping?
(i) It yields thinner canes with lower sugar content. (ii) Increasing risk of pests and diseases.
What is a ratoon meaning?
: a shoot of a perennial plant (such as sugarcane) : a crop (as of bananas) produced on ratoons. ratoon.
What is ratooning What are the advantages of ratooning?
Ratooning is a method by which a sugarcane crop is propagated from the stumps of an already harvested sugarcane crop. The advantage of ratooning is that the cost of cultivation is less; it matures earlier and requires less labour while growing.
What are the advantages and disadvantages of ratoon cropping?
The advantage of ratooning is that the cost of cultivation is less; it matures earlier and requires less labour while growing. The disadvantage is that the ratoon crop is poorer in quality its yield is less and soil is depleted.
What is ratooning state its two advantages?
This is known as ‘ratooning’. Advantages: (i) The crop yields earlier. (ii) The cost of cultivation is reduced as no preparation is done for the fresh crops.
Can rice be harvested twice?
Just as grass lawns regrow after they are mowed, rice fields can regrow after they are harvested. This second harvest – known as a ratoon crop – has traditionally yielded only a small fraction of the first harvest.
What is Relay cropping?
Relay cropping is a method of multiple cropping where one crop is seeded into standing second crop well before harvesting of second crop. Relay cropping may solve a number of conflicts such as inefficient use of available resources, controversies in sowing time, fertilizer application, and soil degradation.
What are the advantages of ratoon?
The main benefits of ratooning are that the crop matures earlier (by one and half month or so) in the season and also decrease the cost of field preparation, preparatory irrigation as well as seed cane used for planting.
What are the relationships of cultivation to the ratoon crop?
Ratooning is the cultivation practice of two harvests in one cropping season by producing a second crop from the original stubble, which could provide higher resource use efficiency and economic benefit compared with direct sown crops.
What is ratoon stunting?
Ratoon Stunting Disease (RSD) was first identified as a disease (on a world basis) in Mackay in 1944. Caused by a bacterium that lives in the vascular system of the cane plant, the disease restricts the plant’s ability to carry water – leading to lower yields.
What is ratoon management?
I. MANAGEMENT OF THE FIELD AFTER HARVEST OF THE PLANT CROP. Complete the following operations within 10 days of harvest of plant crop to obtain better establishment and uniform sprouting of shoots. Incorporate the trash using trash shredder.
What is ratooning State two advantages of ratooning?
What is ratooning method?
Ratooning: In this method, during the first harvest, the sugarcane is cut leaving a little bit of the stalk in the soil with the roots. The stalk soon puts out new shoots or ratoons. The second or any other successive crop obtained from the roots of the leftover crop is called Ratoon.
How many times rice can be grown in a year?
RICE GROWING SEASONS
Hence, two or three crops of rice are grown in a year in eastern and southern states. In northern and western parts of the country, where rainfall is high and winter temperature is fairly low, only one crop of rice is grown during the month from May to November.
What is double cropping rice?
The cereal crop can be harvested in late spring or early summer of the following season. This allows the farmer to plant a shorter-season grain crop immediately after cereal harvest. The result is harvesting two crops in one growing season.
What are the 3 types of cropping patterns?
Cropping Patterns-Mixed Cropping, Intercropping, Crop Rotation.
What is parallel cropping?
Parallel cropping is an agricultural method by which two crops are grown together, in the same land in parallel rows. Both crops grown do not compete for nutrients and have no effect on each other. They can express their maximum yield potential. They are grown in the same growing season.
Which of the following crops are cultivated by using ratoon cropping method?
Ratooning is associated with Sugarcane crops. This is the best method of growing sugarcane. In this method, after harvesting , the lower part of the plant and the roots are left as they were in the field. This give a new crop for the next year without fresh planting.
What causes ratoon stunting disease?
Ratoon stunting disease (RSD) is one of major sugarcane diseases in Indonesia. The causal agent of the disease is Leifsonia xyli subsp xyli. The pathogen systemically infects xylem vessel. Providing healthy seed cane is the most important management of the disease.
What is ratoon stunting disease of sugarcane?
What is ratooning give two advantages of ratooning?
Which month is best for planting rice?
Based on these studies, rice yields are greatest and most consistent from year to year when varieties are planted in late March. Averaged over all the data, rice can achieve 95% or greater of its maximum yield potential when planted from March 20 to April 20.
