2.1 技术简介

技术定义:

The Pre-Monsoon Dry Sowing Technology aims to sow 12 to 15 different crop varieties in April without waiting for rain. To achieve this the seeds are pelletized with a mixture of clay soils, bio-inoculants like dried Ghanjeevamruth and Dravajeevamrit, and ash. The main objective of this technology is to empower rainfed farmers by utilizing the initial rainfall in April and May for crop cultivation. By using pelettized seeds, they can maximize the effectiveness of rainfall showers before the arrival of the monsoon season. Such seeds can also survive, if there are delay in the rainfall as the pellets around the seed help it in maintaining the moisture.

2.2 技术的详细说明

说明:

Pre-monsoon dry sowing (PMDS) is a system of sowing, tilling and tending the land wherein the farmer grows crops in non-farming seasons or whenever there is no crop cover on the land. This can be practised before the advent of monsoon, during summer (April-May), after Kharif and before the beginning of the Rabi season (September and October). PMDS harnesses the water vapor from air that gets settled in the form of early morning dew. The dew supplies the required moisture to the soil. (Reference:-https://apcnf.in/wp-content/uploads/2022/05/IDS-2020-2021-APCNF-PMDS-Report.pdf)

In the study where PMDS was practised before the onset of the monsoon season, typically during the dry month of April. The seeds are pelletized with a mixture of clay soils, bio-inoculants, and ash, which creates a protective coating around the seed and helps it to germinate even in the case of delayed rains or very little rainfall. The coating around the seed, helps it to maintain moisture and support its germination. As the name suggests, the technology is good for utilising the pre-monsoon season by advancing the sowing cycles, using the usually dry months of summer and utilising the pre-monsoon rains.

This technology benefits rainfed areas where farmers rely solely on rainfall for irrigation. PMDS aims to promote an extended duration of crop cover under rainfed conditions, allowing farmers to cultivate crops with a reduced risk of crop failure in the cases of delayed or lower rainfall. Since seeds are germinated before the arrival of monsoon, there are times when they can also survive the heavy rains. This technology is useful in utilising moisture to the best extent possible as seeds are covered with the outer layer of clay and other stuff. In the Mandla District of Madhya Pradesh, farmers utilized seeds from their homes, comprising 12 to 15 crops, including cereals, pulses, and spices. These collected seeds were pelletized, dried for 24 hours, and broadcasted into minimally tilled soil. The diversified crop combination was grown until July and mixed with the soil before paddy transplanting. This process improves the soil's microbial activity, resulting in increased yields in crops grown before paddy and in the paddy crop itself. Therefore, the farmers benefit from increased production and yields through this technique of PMDS.

PMDS not only improves the economics of farmers but it also improves soil health. The covering of the soil with different crops protects it from heat, pounding rain, and wind. It also improves diversity in soil microorganisms, beneficial insects and other species. Covering soil for 365 days with plant diversity is also critical to protect soil health and balance climate change. PMDS can facilitate all these functions.

3.6 包含该技术的可持续土地管理措施

注释:

The PMDS (pre-monsoon dry sowing) technique involves crop diversification and the utilization of rainfed land from April to July, typically left unused, to improve soil health. This is achieved by planting green crops that are later harvested, leaving the crop biomass in the soil to retain moisture, and subsequently growing paddy crops on the same land. This approach has the added benefit of increasing yields, improving crop quality, and reducing farmers' reliance on only one single crop.

3.7 该技术强调的主要土地退化类型

Increase PMDS crop productivity and yield 20-25% subsequent crops, especially paddy crops
Soil structure is improved
Crop Diversification: 12 - 15 different crops are grown on the same piece of land
Fodder availability to animals during the summer season

编制者或其他关键资源人员认为的长处/优势/机会
Ensuring a crop cover for 365 days leads to reduced soil erosion and improved soil health
Maintaining the soil moisture for the subsequent crops, which are cultivated in the rain-fed conditions
Regular practice of PMDS can increase the soil's organic carbon as a lot of green manure is incorporated in the soil resulting in higher carbon content

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险	如何克服它们？
Open grazing of cattle during summer is a common practice. As there are no standing crops in the field, farmers tend to allow their animals for open grazing. However, the cultivation of crops using the PMDS method tends to attract cattle as other fields in the project areas do not have any green cover.	Village-level community institutions can develop a system to minimize the grazing in the fields having crops or the higher adoption of PMDS by the farmers will gradually reduce this risk as PMDS can be a good source of green fodder as well.
Farmers are putting in extra quantities of seeds for various crops for sowing during the PMDS. In normal cases, they will sow the seeds only after the onset of the monsoon and when the field is ready for sowing. Thus in PMDS, they may feel like losing their seeds if there is no germination due to delays in monsoon or other reasons.	Farmers can be supported by providing seeds for the first year to mitigate the risk and exchanging weather-related information in advance. So that they can make an informed decision.

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
Very low to no awareness of the PMDS methodology and benefits among the project farmers.	Regular handholding and demonstrations along with good audio-video documentation for dissemination.
Possible delay in sowing and harvesting of the Kharif and Rabi crops due to delayed monsoon or appropriate soil conditions.	Scheduling the crops based on a crop calendar is one solution; another solution is to explore the seed varieties suitable for delayed sowing.
