How is cotton grown step by step?
Cotton seeds are planted in spring and the plant grows into green, bushy shrubs about one metre in height. The plants briefly grow pink and cream coloured flowers that, once pollinated, drop off and are replaced with fruit, better known as cotton bolls.
What are the stages of cotton?
The developmental phases for cotton can be divided into five main growth stages: (1) germination and emergence (2) seedling establishment (3) leaf area and canopy development (4) flowering and boll development and (5) maturation (Fig. 1). The transitions between these stages are not always sharp and clear.
What are the stages of crop cultivation?
Different stages of crop production
- Ploughing. The loosening of soil for sowing of seed is called ploughing.
- Sowing. Scattering of seeds into the soil is called sowing.
- Adding fertilizers. Seeds require nutrients for proper growth.
- Irrigation. Watering of plants is called irrigation.
- Protection.
- Harvesting.
What is the cultivation season of cotton?
Cotton is a Kharif crop in the major parts of the country viz. Punjab, Haryana, Rajasthan, Uttar Pradesh, Madhya Pradesh, Gujarat, Maharashtra and parts of Andhra Pradesh & Karnataka. In these areas, the irrigated crop is sown from March-May and the rain fed crop in June-July with the commencement of the monsoon.
What is the lifespan of cotton?
There are many cotton producing countries which have a crop life span of 120-130 days rather than 200 or even more as in our country. It is believed that cotton can be successfully grown in July without any loss in yield and quality, instead of May or June.
What are disadvantages of growing cotton?
Like other crops, cotton farming can lead to land clearing, soil erosion and contamination, and loss of soil biodiversity. Poorly managed soils can lead to the loss of soil fertility and declines in productivity.
Which climate is suitable for cotton?
Cotton is a plant that needs a long frost-free period, a lot of heat and plenty of sunshine. It prefers warm and humid climate. Cotton seeds will have a small germination rate, if the soil temperature is below 60°F (15°C). During active growth, the ideal air temperature is 70 to 100°F (21-37°C).
What does the cultivation of cotton requires?
Conditions required for Cotton cultivation Hard-frost is injurious to cotton cultivation and it requires at least 210 frost-free days. Only light-rainfall (50 to 100 centimetres) is preferred. Cotton can also be cultivated under irrigated conditions. It requires high temperature and bright sunshine for its growth.
What are the stages of development of a cotton plant?
Stages of Growth. The developmental phases for cotton can be divided into five main growth stages: (1) germination and emergence (2) seedling establishment (3) leaf area and canopy development (4) flowering and boll development and (5) maturation (Fig. 1).
How tall does cotton plant grow in India?
Nearly 21 per cent of the area in India is under herbaceums. These are known as upland cotton and about 90 per cent of the current world production use this species. This is a small annual shrub 1 to 1.5 m tall. The stem is usually green or brown with leaves and twigs glabrous to densely heavy.
How long does it take a cotton plant to germinate?
Under favorable germination conditions, the radicle (root) emerges within two to three days. The radicle becomes the taproot that grows downward into the soil. The taproot penetrates the soil rapidly after germination and may reach a depth of up to 10 inches or more by the time the cotyledons unfurl (5 to 7 days, 50 DD60s) (Fig. 2).
When does a cotton plant produce a white flower?
The time requirement for a square to develop into a white flower is not influenced significantly by external conditions or plant stress. Throughout the remainder of the season, the cotton plant, due to its indeterminate growth habit, will continue adding vegetative growth at the same time as the reproductive development.
