Frequently Asked Questions

What are the recommended nitrogen and potassium rates for high-yield onion crops?

The recommended nitrogen rates for high-yield onion crops range from 130 to 200 kg per hectare, while the recommended potassium rates range from 60 to 250 kg per hectare.

Why is potassium nitrate recommended for onion cultivation?

Potassium nitrate is recommended for onion cultivation because it has the lowest contribution to root zone salinity compared to other potassium sources. Onions are highly susceptible to root zone salinity, and high chloride levels can lead to significant yield losses.

What is the effect of increasing rates of potassium fertilizer application on onion yield and quality?

Field experiments have shown that increasing rates of potassium fertilizer application can result in higher bulb yield and improved quality of onions. Application of 100 kg K2O ha-1 resulted in the highest bulb yield, while the quality of the crop was improved by increasing the total soluble solids, non-reducing sugars, and chlorophyll content.

How is nutrient balance influenced by different potassium treatments in onion crops?

Different potassium treatments can influence nutrient balance in onion crops. Higher nitrogen and potassium tissue concentrations result in increased nutrient offtake. Stagnation in yield increase beyond the application of 100 kg K2O ha-1 was observed due to a lack of nitrogen.

What is the recommended ratio of nitrate to ammonium nitrogen for optimum yield, quality, and storability of onions?

For optimum yield, quality, and storability, a ratio of 75% nitrate to 25% ammonium of the total nitrogen applied is recommended. Potassium nitrate helps achieve this desired ratio.

Why is balanced plant nutrition crucial for optimizing yield and quality in onion production?

Balanced plant nutrition is crucial for optimizing yield and quality in onion production because onions have a shallow fibrous root system and require multiple topdressings of nitrogen and potassium for optimum yields. Eighty percent of the nutrients supplied to the onion plant end up in the bulb, and the carbohydrates produced by the leaves are translocated to the bulb during bulb formation.
