Due to nCovid19 manufacturing and industrial sectors are facing a lock down and so does the service sector while the farming sector continues to work. Hence this question.
In some scenarios, the price reduction is shown, the cultivation areas will constant, as well as the volumes of some products. The greatest variations will be seen in the other parts of the chain, such as transport, biosecurity costs, etc.
This is certainly a very important question and there is possibly not a unique answer that applies to all countries or regions in the world. In some places, the agricultural sector will be enhanced with the consideration that it is an essential production. In other places, agricultural output will suffer. It is not only a question of production which may increase in general. It is a question of supplying markets and it is here where the pandemic can disrupt supply chains. We also need to differentiate between short-term effects that translate into supply disruptions through different mechanisms and medium- and long-term effects which affect the willingness to invest in the farming sector.
Industrial sector will recover and agro-industrial sector (transformation of food raw material) has not stopped. Therefore, I do not expect a significant increase of the Agriculture sector to GDP due to pandemic effects.
I agree with Carlos Rodríguez-Monroy , I would add the issue of Postharvest losses which can probably hinder the contribution of Agriculture to GDP, especially in Africa.

Most likely, the share of agriculture sector would increase, given that agriculture production (food production in particular) involves shorter time as compared to industrial production or services sector activities. In many countries, though the share of agriculture in the GDP may be low, still, it is quite likely that the absolute value of agriculture production might increase even in the high income countries. This could also be reasoned by a psychological shift in food consumption behaviour, which is anticipated in the post-Covid-19 context. Concerns of regional and local food security challenges have been on the rise in the context of Covid-19 crisis as well. Many developing countries, including India, are also experiencing the return of immigrants (especially, unskilled and semi-skilled workers) following loss of employment in other countries, especially, the Arabic gulf countries. This may cause a pressure of people in the rural areas, which may also cause an increase in agriculture and farm related activities, as the immediate options of survival and livelihood enhancement.
