in case there is shortage of water in farm
Answers
Answer:
Water scarcity has a huge impact on food production. Without water people do not have a means of watering their crops and, therefore, to provide food for the fast growing population. According to the International Water Management Institute , agriculture, which accounts for about 70% of global water withdrawals, is constantly competing with domestic, industrial and environmental uses for a scarce water supply. In attempts to fix this ever growing problem, many have tried to form more effective methods of water management.

Explanation:
Water Shortage and Salinity Stress
Water shortage is the most common environmental stress affecting banana, even in the tropics. Therefore, watering is mandatory in the subtropics and beneficial in tropical dry periods. Mediated by ABA and hydraulic signals, the isohydric banana closes its stomata with increased soil water shortage and increased leaf to air vapor pressure difference. Leaf water potential is thus maintained, but photosynthesis is much reduced, yet recovery occurs when water becomes available (Figure 16). Banana is extremely susceptible to salinity in general and to sodium in particular. Increase in ground water osmotic pressure reduces water availability with the consequences detailed earlier. This situation, however, can be remedied by increase in water application.
