3、NPS Fertilizer and Spacing Effects on Yield and Quality of Coriander

Among the tested rates of NPS fertilizer and inter-row spacing, it can be concluded that using 100 kg ha –1 NPS fertilizer with 30 cm inter-row spacing was found to be optimum for growth, yield and quality of coriander production.

4、Impact of NPS Fertilizer and Plant Spacing on Coriander (Coriandrum

This review comprehensively examines the effects of NPS (Nitrogen, Phosphorus, and Sulfur) fertilizer and plant spacing on the growth, yield, and quality of coriander.

Effect of Irrigation and Fertilization on Growth and Yield in Coriander

Coriander needs adequate moisture for its growth and development and responds greatly to applied nutrients, varying widely from place to place depending upon fertility level of the soil and other environmental conditions.

Nitrogen fertilisation in coriander (Coriandrum sativum L.): a review

In most cases examined, N fertilisation allowed a 10–70% increase in seed yields in comparison with each respective untreated control. The efficiency of use of this element, however, has proven to be greatly dependent on the overall fertility conditions of the growing site.

EFFECTS OF NITROGEN FERTILIZATION ON CORIANDER CORIANDRUM SATIVUM L

coriander and interaction (year x fertilizer) factor is significant for Argentinean coriander (p<0.05). In their study about nitrogen doses and density effect on coriander quality, Moosavi et al. (2013) found that nitrogen doses have positive significant effect on essential oil rate of coriander

Influence of Nitrogen Sources Applied by Fertigation to an Enriched

This study aimed to analyze the effect of inorganic nitrogen source applied by fertigation to an enriched soil with organic compost on plant growth, mineral nutrition, and the quality of coriander transplanted in two consecutive harvests.

Guide to Fertilizing Your Coriander Plant

Yes, it is necessary to fertilize coriander plants grown in pots. Container-grown plants do not have access to the same amount of nutrients as those grown in the ground, so they require regular fertilization to maintain their health and vigor.

How to Fertilize Coriander for Optimal Growth?

In early spring, apply a balanced fertilizer to kickstart growth. Again in mid-summer, a light application can help sustain the plant through the hotter months. Avoid fertilizing in fall and winter as the plant's growth slows down, and the nutrients might not be utilized effectively.

Nitrogen fertilizer is one of the essential nutrients for plant growth, playing a critical role in the development of vegetables like coriander. the demand for nitrogen may change as plants enter their later growth stages. This article explores whether nitrogen fertilizer is still required for coriander in its later stages, the reasons behind this need, and offers practical recommendations.

I. Nitrogen Requirements for Coriander in the Later Stages

1. The Role of Nitrogen Fertilizer

Nitrogen fertilizer is a key nutrient that promotes stem and leaf growth. During the early growth stages, appropriate nitrogen application stimulates root development and enhances photosynthetic efficiency, accelerating plant growth. as plants mature, their demand for nitrogen gradually decreases.

2. Nitrogen Consumption and Transformation

During growth, plants absorb nitrogen and convert it into organic compounds like amino acids and proteins, which are vital for development. In later stages, the need for nitrogen diminishes, so the amount of nitrogen fertilizer should be reduced accordingly.

3. Methods to Supplement Nitrogen

If soil nitrogen levels are low in the later stages, supplements like urea can be applied to support growth. Adjusting the timing and method of fertilization can also help meet the plant’s nitrogen needs.

II. Reasons Why Coriander May Not Require Nitrogen in Later Stages

1. Changes in Growth Phases

Coriander is an annual herbaceous plant with a short lifecycle. While nitrogen is critical during early growth, the demand declines significantly in later stages, reducing the need for excessive nitrogen application.

2. Soil Nitrogen Content

Soil nitrogen levels often drop in the later stages as plants absorb and transform nitrogen into organic matter. Low soil nitrogen can hinder growth, but over-fertilization is unnecessary once the plant’s needs decrease.

3. Fertilization Practices

Fertilization strategies should adapt to growth phases. Nitrogen should be applied generously during peak growth periods but scaled back in later stages to avoid overstimulation or other issues.

III. Rational Nitrogen Application for Coriander in Later Stages

1. Controlling Fertilizer Quantity

Reduce nitrogen usage in later stages to prevent excessive growth or potential problems. Adjust dosages based on soil nitrogen levels and plant condition.

2. Choosing Fertilization Methods

Combine organic and inorganic fertilizers. Organic options improve soil structure, while inorganic ones provide quick nitrogen replenishment. Tailor the mix to soil conditions and plant needs.

3. Timing Fertilization

Apply nitrogen primarily during peak growth phases. In later stages, minimize frequency and quantity to align with the plant’s reduced demand.

Excessive nitrogen is unnecessary for coriander in later growth stages. Fertilization should be adjusted based on soil nitrogen content and plant development to ensure healthy growth while avoiding over-fertilization risks.
