| Rice ( Oryza sativa ) | |
|---|---|
| Climatic requirement: | Rice crop need hot and humid climate. It is best suited for the regions having high humidity, prolonged sunshine and an assured supply of water. The average temperature required throughout the life span of a crop is from 21-37° C. At the time of cultivation it requires higher temperature than growth. Temperature requirement for blooming is in the range of 26.5-29.5°C |
| Season: | Rice-growing season varies in different parts of India, depending on temperature, rainfall and other climatic conditions. In parts of eastern and peninsular India, the mean temperature throughout the year is favorable for rice cultivation hence 2-3 crops of rice are harvested in a year. In northern and western part of India where winter temperatures are fairly low only one crop of rice is harvested during the Kharif season. |
| Soil: | Soils with good water retention capacity with good amount of clay and organic matter are ideal for rice cultivation. Clay or clay loams are most suited for rice cultivation. Such soils are capable of holding water for long and sustain crop. Rice being a semi-aquatic crop, grows best under sub-merge conditions. It grows well in soils having a pH 5.5-6.5 |
| Method of sowing: |
1. Dry or Semi-Dry Upland Cultivation i) Broadcasting the seed ii) Sowing the seed behind the plough or drilling 2. Wet or Lowland Cultivation i) Transplanting in puddled fields ii) Broadcasting sprouted seeds in puddled fields |
