The biggest problem of farmer in developing countries inlcuding india is the challenge of sustaining the farm productivity with better production returns...

Good question!

Better to do your research knowledge gaps among farmers, social groups, gender, age groups for different crop management! How is the knowledge transfer over generation? What is the interest of different social groups? What is the limiting factor for technology use for the different members of the society mentioned above? These are only few of the research questions? You many also deeply and carefully look at , at what stage of the research should farmers participate for the selection of any crop variety?

1. India, we are following many modern techniques to increase crop's yields. Either it is eco-friendly or not, we continue giving importance to improve the crop yield as to withstand the increasing population. Therefore, we lost the uniqueness of olden day's agriculture as these modern techniques reduce the strength of the crops and also reduce land's fertility.

2. Irrigation problems (water sources)

3. Unpredictable climate

4. Pest and diseases of different agri horti crops.

crop management and smart agriculture

crop management and big data

crop management and IoT

crop management and high-tech, such as irrigation system, drone, organic fertilizer etc.

crop management and AI

There are many topics you can choose. You can google it or use google scholar.

This is just my understanding. Hope it can help. Thanks and have a nice day.

One of the most important problems is crop wastes, especially when all of the crop cannot been harvested because of it's low price so cannot be able to compensate the cost of harvesting.

In this case, all of water, fertilizers, pesticides, soil, and all of resources used in crop culture are wasted.

Haven't your farmers this problem?

Why don't you go for on farm soil analysis?

Soil testing it self a tedious process. If farmer can analyze soil in their farm, i will be very much help full for them. Using modern technologies can you develop on-site micronutrients testing device. Many techniques are available but those are not cost effective.

Artificial intelligence with ancillary soil data can also be useful.

Developing sensors for irrigation and fertilization based on field moisture and nutrient content can also be a major break through.

Modeling and developing apps for calculating soil quality indices as well as product quality can help scientists as well as farmers.

Thank you

Thanks for your nice attention,

But I should explain that the main problem is lack of crop harvesting due to their low prices.

So, Iow prices, Deprive poor farmers the ability of harvesting.
