Foliar spray is a widely used technique in modern agriculture for the enhancement of crop yields. It involves the application of plant nutrients and growth stimulants directly onto the leaves of crops. Wheat crop, being the major source of food, has gained immense importance in recent times. It is essential to increase the yield of wheat crop to meet the growing demand for food grains. The application of foliar sprays has emerged as an effective tool in increasing the grain yield of wheat.
Foliar spray of nutrients like nitrogen, phosphorus, potassium, and micronutrients has been reported to increase the yield of wheat crop. These nutrients are essential for the proper growth and development of the crop. The application of foliar sprays has been found to increase the uptake of nutrients by the crop, thereby promoting its growth and development. The application of foliar spray at different growth stages of the wheat crop has shown significant improvement in grain yield.
Apart from the nutrient sprays, plant growth stimulants like gibberellic acid, cytokinins, and auxins have also been found to increase the grain yield of wheat crop. These growth stimulants promote cell division and elongation, thereby leading to higher biomass accumulation and ultimately higher grain yield.
However, the timing and method of application of these sprays play a crucial role in their effectiveness. It is essential to apply the sprays during the appropriate growth stage when the crop is most receptive to the nutrients and growth stimulants. The dosage and frequency of application should also be carefully monitored to avoid overuse or wastage.
In conclusion, the application of foliar sprays is an effective technique for increasing the grain yield of wheat crop. It provides an efficient and cost-effective method for nutrient and growth stimulant application while reducing soil degradation and nutrient leaching. However, careful monitoring and proper application are required for optimal results. With the help of foliar sprays, wheat crop production can be enhanced, ensuring sufficient and sustainable food production for the growing population.
