Intercropping is a farming technique where two or more crops are cultivated together in the same field, simultaneously or sequentially, to maximize land utilization and enhance productivity. One such intercropping combination that has gained popularity among farmers is toria and gobhi sarson (Indian mustard).
Toria (Brassica rapa subsp. rapa) and gobhi sarson (Brassica rapa subsp. dichotoma) are both brassica crops belonging to the mustard family. Toria is primarily grown for its seeds, which are rich in oil and protein content. On the other hand, gobhi sarson is cultivated for its leaves, which are used as a vegetable in many culinary preparations.
Choosing the right sowing time for intercropping toria and gobhi sarson is crucial for optimal growth and yield. These crops have slightly different sowing requirements, and finding the perfect balance is essential for successful intercropping.
Ideally, sowing toria and gobhi sarson together is done during the late monsoon or early winter season, depending on the geographical location. In most regions of India, the sowing window for toria and gobhi sarson intercropping is between late September and mid-October. However, it is essential to consider local climatic conditions and frost dates for proper planting.
Before sowing, preparing the field is crucial. The land should be thoroughly plowed and leveled to create a suitable seedbed for both toria and gobhi sarson. Adequate soil moisture is vital for germination and establishment, so farmers should ensure timely irrigation before sowing.
When sowing toria and gobhi sarson together, a proper seed rate and spacing are key factors. Generally, toria is sown in rows spaced at about 30-40 cm apart, with a seed rate of 4-6 kg per hectare. Gobhi sarson, being primarily cultivated for its leaves, requires a higher density. It is sown broadcasted or in close rows with a seed rate of 1-2 kg per hectare.
The intercropping of toria and gobhi sarson offers numerous benefits. First and foremost, it maximizes land utilization, allowing farmers to grow two profitable crops simultaneously. Additionally, their growth patterns complement each other, as the taller toria provides shade and acts as a support for the gobhi sarson plants while reducing weed growth.
Intercropping toria and gobhi sarson also promotes biodiversity in the field, attracting different beneficial insects and pollinators that aid in pest control and enhance yield. Additionally, the deep root system of these crops improves soil structure and nutrient availability.
Harvesting time for intercropped toria and gobhi sarson largely depends on the specific purpose of cultivation. Gobhi sarson leaves can be harvested as early as 30-40 days after sowing, while toria seeds are usually ready for harvesting after 90-120 days. Harvesting can be done manually or with the help of machinery, depending on the scale of cultivation.
In conclusion, intercropping toria and gobhi sarson is a viable agricultural practice that can bring multiple benefits to farmers. With the right sowing time, adequate land preparation, and proper seed rates, farmers can enjoy increased productivity, efficient land utilization, improved soil health, and diversified income streams.
