What foliar fertilizer makes peanuts high-yielding? These several are recommended and work well
Foliar fertilizer is a type of fertilizer in which nutrient elements are applied to the surface of crop leaves and perform their function through absorption by the leaves. As a supplement to the nutrients plants absorb, it makes up for the insufficiency of nutrient uptake by the roots. It is worth noting that foliar fertilization cannot replace soil fertilization. Let us take a look below at which foliar fertilizer is best for high-yielding peanuts!
Which foliar fertilizer is best for high-yielding peanuts?
Peanut foliar fertilizer has the effects of a high fertilizer absorption and utilization rate, saving fertilizer, and significantly increasing yield. Major elements such as nitrogen, phosphorus and potassium as well as trace elements such as calcium, molybdenum, boron, manganese and iron can all be applied to the leaves. Foliar application of nitrogen fertilizer noticeably increases the number of full pods per plant, foliar application of phosphorus fertilizer generally increases yield by 7-10%, and foliar application of trace fertilizers such as aluminum, boron, manganese and iron generally increases yield by 8-10%. When choosing foliar fertilizer for peanuts, it is best to choose a brand registered with the Ministry of Agriculture, and choosing a dedicated-type foliar fertilizer is better.
Principles of peanut fertilizer requirements
1. Major elements: The ratio of demand of peanuts for the three major elements nitrogen, phosphorus and potassium is 3:0.4:1, with nitrogen the most, potassium next, and phosphorus the least. For this reason, when topdressing major-element fertilizer, nitrogen should be the main one and potassium applied in an appropriate amount.
2. Trace elements: Peanuts have the greatest demand for several elements such as calcium, sulfur and magnesium. Calcium can promote faster growth of peanut plants, sulfur can increase the protein content of the kernels, and magnesium can promote the normal formation of chlorophyll in peanut leaves.
How to use peanut foliar fertilizer
1. Fertilizer dilution: Take 35 grams of concentrated liquid fertilizer and add 20 kg of clean water, dissolve and stir evenly. Tap water is best; pond water and rainwater contain more impurities.
2. Foliar spraying: When spraying peanut foliar fertilizer, focus on the undersides of the peanut leaves and spray evenly. A sprayer with a good atomizing effect can be chosen, which helps leaf absorption.
3. Spraying time: The best time to spray peanut foliar fertilizer is from after flowering to the beginning of pod setting, spraying once about every 10 days, which can play a role in enlarging the pods and increasing yield.
Precautions for peanut foliar fertilizer
1. The fertilization time should be determined according to the growth condition and growth stage of the peanuts; generally it should be applied in the later growth stage.
2. Choose a windless cloudy day or, on a sunny day, before 9 a.m. and after 4 p.m. to spray, so as to increase leaf absorption and prevent damage to the leaves.
3. Strictly control the spraying concentration; a high concentration easily damages the leaves and causes fertilizer burn.
4. When spraying peanut foliar fertilizer, spray evenly and finely, and spray both the front and back sides of the leaves.
