Short-Duration Crops Can Give Farmers Another Harvest, How Does It Work?

Farmers do not always need more land to increase farm output. In some cases, they can make better use of the land they already have by choosing crops that mature earlier. Short-duration varieties can create enough time between two main crops for farmers to add another crop to their annual calendar.

The approach is already being used in several parts of India. ICAR has developed early-maturing varieties of rice, pulses and other crops that can fit into different cropping systems. The aim is not simply to harvest earlier, but to use the remaining season for another productive crop.

This can increase cropping intensity, but farmers need to consider water, labour, soil fertility and market demand. Growing two crops instead of one does not automatically mean higher profit. The second crop must have enough time to mature and must generate more income than its additional costs.

How Much Time Can Farmers Save?

Pusa Basmati 1509 is one clear example. ICAR says the variety matures in about 115 days, around 30 days earlier than Pusa Basmati 1121. Its shorter duration can give farmers more time to prepare the field for a following wheat crop.

ICAR also reports that Pusa Basmati 1509 can save three to four irrigations and about 33% of water compared with longer-duration cultivation. For farmers facing limited irrigation, an earlier harvest can therefore provide both a time advantage and a water-saving opportunity.

Short-duration pulses offer another option. Mungbean varieties such as IPM 410-3 and IPM 205-7 have been promoted for spring and summer cultivation. ICAR research found that these crops can fit into fallow periods and improve land-use efficiency while adding nitrogen to the soil.

ICAR’s research on spring-summer mungbean in Uttar Pradesh reported yields of 12.20–16.72 quintals per hectare under improved practices, compared with 9.75–11.14 quintals under traditional practices. Demonstrating farmers reported additional income of roughly ₹1.02–1.07 lakh under the programme.

The answer depends on the local cropping calendar. A farmer needs to know when the first crop will be harvested, how quickly the field can be prepared and how much time the next crop needs before weather conditions become unsuitable.

A short-duration crop can create a window, but that window can disappear if harvesting is delayed. Farmers should therefore select varieties according to their actual sowing and harvesting dates rather than relying only on the maturity period printed on a seed packet.

Water availability is another major factor. A second or third crop may require irrigation during a period when rainfall is limited. Farmers should calculate the total water requirement before increasing cropping intensity.

Which Crops Can Fit Into the System?

Pulses are particularly useful for short windows because several varieties have relatively short growing periods. Mungbean, blackgram and some early pigeonpea varieties can be used in suitable regions. The choice should depend on local climate, soil, irrigation and the time available between major crops.

ICAR has also developed Pusa Arhar 16, an extra-early pigeonpea variety that matures in about 120 days. Its compact plant type allows high-density planting, while its early maturity can permit another crop such as mustard, wheat or potato after harvest in suitable systems.

Groundnut also has relatively early varieties. ICAR lists Girnar 4 and Girnar 5 with maturity around 112 days under recommended Kharif conditions in several states. These varieties were developed with high oleic acid content and can provide another option where local conditions are suitable.

Farmers should not choose a short-duration variety simply because it matures quickly. Yield, disease resistance, market demand and input requirements matter too. An early variety with poor performance in local conditions may earn less than a longer-duration variety with a reliable yield.

Some short-duration crops can provide benefits beyond their harvest. Pulses fix atmospheric nitrogen through their association with beneficial soil bacteria. This can contribute to soil fertility and make pulse-based cropping systems useful for diversification.

Mungbean is a good example. ICAR describes it as a crop that can improve land-use efficiency while contributing to soil fertility through nitrogen fixation. Growing it during a fallow period can therefore create an additional harvest without leaving the field unused.

Farmers still need to manage nutrients carefully. A pulse crop does not mean the following crop will require no fertiliser. Soil testing should guide nutrient management, and farmers should return crop residues where appropriate rather than removing every part of the crop from the field.

What Should Farmers Check Before Adding a Crop?

The first calculation should be time. Farmers should map the complete season from sowing to harvest and identify where a short-duration crop can fit without delaying the main crop.

The second calculation should be money. Farmers need to include seed, land preparation, fertiliser, irrigation, labour, plant protection, harvesting and transport. The expected market price should then be compared with the total cost.

Farmers should also check whether buyers are available. A short-duration crop is useful only if its produce can be sold at a reasonable price. FPOs, cooperatives and local traders can help farmers understand demand before sowing.

Short-duration varieties are therefore not simply a way to harvest faster. They can give farmers more choices about how to use their land throughout the year. When the crop calendar, water supply and market all line up, an extra crop can turn an unused period into another income opportunity.

The key is to plan the entire year rather than each crop separately. Farmers should ask what comes before the crop, what follows it and whether the transition can happen on time. This whole-season approach can make multiple cropping more practical and reduce the risk of adding a crop that does not fit the farm.
