Impact of the foliar application of potassium nanofertilizer on biomass, yield, nitrogen assimilation and photosynthetic activity in green beans

The agricultural areas of the world face problems that create difficulties when producing food and excessive use fertilizers is generating a negative environmental impact. An alternative appears as solution to this problem nanofertilizers. Within nanofertilizers an area opportunity application macronutrients, which report increase in absorption efficiency 19% compared conventional fertilizers. Potassium (K) one three macronutrients most used agriculture its deficiency affects key processes plant development, limiting crop production. However, number publications where K nanofertilizer limited, despite this, products form are already on market. Therefore, aim research work was study effect foliar biomass, yield, nitrogen assimilation photosynthetic activity green beans cv. ‘Strike’. applied doses 0, 50, 100 200 ppm. biomass accumulation, nitrate reductase enzyme activity, pigments were evaluated. dose ppm obtained higher accumulation SPAD values total chlorophyll content. While 200-ppm yield. results suggest benefits physiological development plants. more studies required compare with traditional
