Crop pattern refers to the proportion of area under different crops at a particular period of time. A change in cropping pattern means a change in the proportion of area under different crops. It can be described in a number of ways but the most convenient method is to classify the agricultural production into two groups i.e. food grains and non-food grains. They have been discussed as below:
1) Mono Culture: The Practice of growing a single crop in a large area in particular cropping season. It is typical in commercial farming however it is also popular in Indian where subsistence farming is practiced. Rice & Wheat in Punjab are grow almost in a manner resembling monoculture –

2) Double Cropping: There are two Types of double dropping.
Inter Cropping
Practice of grow more than one crop on the same field in the same growing season it is achieved planting two or more crops in rows, mustard & Wheat in Punjab 'and Haryana traditionally cultivated (20 rows mustered & 30 rows wheat).
Relay Cropping
Grow two crops simultaneously making the crop selection in such a manner that while one crop matures and is harvested the other crop has already started growing. It is generally practiced in well, distributed annual rainfall those areas where assured irrigation facilities are available. For ex- Soyabean can be planted while wheat matures.
3) Mixed Cropping
Refers to growing variety of crops in a particular growing season under this system different crops are grown on different fields. It is typical of the areas of subsistence farming where farmers try to produce everything. Whatever they need they cultivate on their on farmland. This practice is just opposite to monoculture.
4) Multiple Cropping
Practice of growing more than one crop in a year on the same land. This practice can be only adopted in areas where the rainfall is well distributed over the year or assured means of irrigation is available. Fertility of land will also be maintained usually by the use of manures and fertilizers, No land kept fallow is this practice. It is also practiced in the areas of Green Revolution.
CROP PRODUCTIVITY TRENDS
Crop productivity is measured as the ratio of agricultural outputs to agricultural inputs, e.g. yield per hectare. Before independence the productivity of food grains showed a decline. With the introduction of economic planning in 1950-51, and with special emphasis on agricultural development, there was a steady increase in the productivity
In last three decades, India has seen significant progress towards increasing production, yield levels and crop diversification. Still, the agricultural productivity in India i.e. average yield per hectare is among the lowest in the world. Also there exist vast differences in productivity between states[1].
Causes for Low Productivity: Some of the main factors are as follows:
The Rural Infrastructure Development Fund (RIDF) has emerged as an important scheme for financing rural infrastructure projects of the State Govts. The RIDF was set up by the Government in 1995-96 for financing ongoing rural infrastructure projects. The Fund is maintained by the National Bank for Agriculture and Rural Development (NABARD).Domestic commercial banks contribute to the Fund to the extent of their shortfall in stipulated priority sector lending to agriculture.
