Rice is among the most widely grown grain crops in India because it is a staple food for the entire population. Only China is ahead of India in rice production worldwide. During 2023-24, total rice production was around 1132 lakh metric tonnes (LMT) . Also, as per the First Advance Estimates, the total Kharif rice production is expected to be 1199.34 LMT for 2024-25 . Different varieties of rice are grown in India and have unique tastes, aromas, and sizes. Basmati, Ambemohar and Kalanamak are some popular examples.
Rice is mainly cultivated in tropical and rain-fed regions, and top rice-producing states in India include Uttar Pradesh, Telangana and West Bengal. Farmers across the country undertake different rice cultivation practices based on factors like terrain, scale of cultivation, water availability and cultural influence. In addition, modern cultivation methods have emerged that promise less water wastage and higher yield.
The traditional rice cultivation method is a common practice in India because of its cost efficiency. Also, it is well-suited for areas with high rainfall and low labour costs.
The steps involved in this method are:
This method demands effective water damming and channelling to prevent weed growth. The field is kept submerged in water during the growing season.
DSR involves sowing rice seeds directly into the ground instead of transplanting the seedlings. A seed drill is used to sow these seeds into the soil directly at uniform depth and spacing. Due to uneven soil, seed drill operations may become limited, resulting in poor crop establishment. This is why a land leveller is used before sowing to ensure a uniform surface. Crop establishment can be improved by priming rice seeds with water and Potassium chloride (KCl).
DSR is mainly done in two ways:
The SRI rice cultivation method is becoming popular among farmers as it effectively manages resources like water, labour, seeds, and land. Rather than a technology, it is a methodology or set of management practices that work to increase the crop yield with fewer resources.
The necessary conditions in the SRI method are:
The SRI method is preferred because it encourages soil biotic activities in the root zone and uses fewer chemical inputs and seeds. Such practices not only save inputs significantly but also enhance yields. Overall, it ensures higher profits for rice cultivators.
The use of machinery has made rice cultivation easier and more productive. Some of the important machineries used in paddy cultivation are seed drill and rice transplanters. Let us see one by one.
A seed drill is an important machinery used for the direct sowing of rice in fields. Some popular types of seed drills for direct seeding are inverted zero till drills, conventional seed cum fertilizer drills and machines with vertical or inclined plate metering mechanisms.
One of the main benefits of using a seed drill is that it minimizes seed breakage while maintaining uniform spacing between seeds and rows. The recommended depth to sow seeds via dry DSR is 2 to 3 cm. In the case of pre-sowing irrigation, the sowing depth is 3 to 5 cm. The ideal inter-row distance is 20 cm.
A manual rice transplanter is operated by hand to transplant rice seedlings manually. It is usually ideal for hilly areas and small to medium-sized fields. This compact machine can plant multiple rows simultaneously and thus comes in different sizes, like 2 rows and 4 rows.
In a walk-behind rice planter, the machine moves forward while the operator walks behind to guide it across the field. When the handle is pressed, seedlings are picked up by forks to be planted in rows. So, the operator needs to punch the handle at the desired spacing while pulling the machine. This is why it can be a two-person task.
This machine needs high manual labour and more time; thus, it is not suitable for large rice fields.
One of the most modern machineries for rice plantation is a self-propelled rice transplanter. This machine has an engine of its own to move in the field, and this does not need manual force by the operator. Mat-type rice seedlings can be easily transplanted in puddled soil with this machine.
This machine offers high efficiency with features like automatic hydraulic levelling control. Also, it is easy to operate and operates faster and stronger in deep fields. Further, the transplanting depth can also be adjusted. It saves a significant amount of time and labour in comparison to manual transplanting.
The top brands offering such rice transplanters in India are Kubota and Mahindra. Some popular rice transplanter models are Kubota NSP 4W, Mahindra Planting Master Paddy 4RO and Mahindra MP461.
Traditionally, farmers have been using manual transplanting by hand to plant rice. It makes the entire process highly laborious and time-consuming. In addition, consistent crop spacing is challenging to achieve with hands, leading to unoptimized resource utilization and uneven growth. Compared to the traditional method, there are certain advantages of using machineries in rice cultivation. These are:
Overall, rice transplanter machines offer a wide range of benefits over manual transplanting, making them a competent alternative.
Rice cultivation is a common practice across India. Different methods of rice plantation are used in different regions. However, as labour and water are becoming expensive and limited resources, it is important to adopt methods that use them efficiently. In addition, self-propelled rice transplanters are effective machines that save time and labour while preventing seed waste.
