Scallop squash fruits may be harvested at different stages of development. Small size fruits, intended both for the fresh market and the food industry, have the highest biological value. This study was conducted to determine the yield potential of scallop squash cultivars (‘Polo F1’, ‘Disco’, ‘Gagat’, ‘Okra’, ‘Sunny Delight F1’) grown on mulched (black polyethylene foil or black agrotextile) or unmulched soil, and harvested when fruits reached a diameter of 3–6 cm. Based on 3-year average data, the highest marketable and early yield was produced by ‘Sunny Delight F1’. This cultivar is also appreciated by consumers for its yellow colored skin of fruits. Another advantage of this cultivar was its high nutritional value expressed by the highest content of dry matter, vitamin C, polyphenols and minerals (K, P, Ca, Mg), with limited tendency to nitrate accumulation. Among the other cultivars tested, ‘Okra’ showed high yield potential, ‘Gagat’ was a rich source of carotenoids, and ‘Disco’ – polyphenols. Black polyethylene foil and black agrotextile appeared to be equally effective mulching materials. The benefit from the application of mulch was a significant increase in yield without any change in the chemical composition of the fruit.

Poland represents a country with relatively low agricultural productivity but high potential, particularly for certain crops. The aim of our study was to: (i) Show the potential to increase crop yields to sustainable levels of wheat and rapeseed in Poland based on simulations in the Global Agro-Ecological Zones (GAEZ v3.0) model (ii) Show the yield gap for wheat and rapeseed for Poland (iii) Compare yield gaps in Poland with yield gaps of neighbouring counties: Germany, Czech Republic, and Slovakia (iv) Discuss the potential of agricultural productivity increase along with challenges and pragmatic requirements associated with increasing agricultural productivity in Poland To our knowledge, this is the first study that discusses spatially sustainable intensification of agriculture in Poland and critically assesses opportunities pertinent to such intensification. The results show that Polish agriculture can play an important role in contributing to sustainable agricultural productivity increase in a resource-constrained world. The results presented here also demonstrate that yields can even be doubled, yet significant investment and relevant know-how for agriculture must be provided.
