Praktikum IHT 1 | Defisiensi Hara Makro | Oktober 2023

Summary

This video presents a detailed study of nutrient deficiencies in plants, focusing on key elements such as calcium, magnesium, potassium, and nitrogen in various crops like kangkung, pakcoy, and papaya. Groups from different locations in Bandar Lampung share their observations on how these deficiencies manifest in plant health, including yellowing leaves, stunted growth, and poor root development. The video also covers practical solutions such as proper fertilization, soil adjustments, and moisture management to address these issues, emphasizing the importance of understanding and mitigating nutrient deficiencies for healthy, productive plants.

Takeaways

• 😀 Deficiency in essential nutrients such as nitrogen, potassium, calcium, and magnesium can significantly affect plant growth and productivity.
• 😀 Calcium deficiency in vegetables like sawi, kangkung, and pakcoy can cause stunted root growth, weak plant development, and reduced flower production.
• 😀 Plants suffering from calcium deficiency often show yellowing at the leaf edges, curling, and eventually leaf drop.
• 😀 Magnesium deficiency leads to chlorosis (yellowing) between leaf veins and can cause leaf necrosis, resulting in poor plant growth and yield reduction.
• 😀 Magnesium-deficient plants may drop older leaves and have impaired biochemical and physiological processes.
• 😀 Nitrogen deficiency in vegetables like kangkung and bayam is evident through yellowing of leaves, slow growth, and stunted plants.
• 😀 Nitrogen-deficient plants also show yellowing in older leaves, starting at the tips or edges, with the leaves curling downward.
• 😀 Potassium deficiency in papaya plants causes older leaves to exhibit yellowing, with edges that turn brown and eventually dry out.
• 😀 Potassium-deficient plants are more vulnerable to diseases and environmental stress, leading to reduced productivity.
• 😀 Farmers can mitigate nutrient deficiencies by applying the correct types of fertilizers, adjusting soil pH, and ensuring consistent moisture in the soil.

Q & A

What is the purpose of the survey conducted in the video?

The survey aims to identify nutrient deficiencies, specifically calcium, magnesium, and potassium, in various vegetable and food crops.

Where was the survey for calcium deficiency conducted?

The survey was conducted in the Waikandis village, Tanjung Senang district, Bandar Lampung city, Lampung province, Indonesia.

What are the symptoms of calcium deficiency in plants observed in the video?

Symptoms of calcium deficiency include yellowing of leaf edges, poor root development, weak plant growth, curling and small leaves, and stunted flowering.

How do farmers address calcium deficiency in Pakcoy plants?

Farmers address calcium deficiency by applying appropriate calcium fertilizers according to recommended doses, adjusting soil pH, and maintaining consistent soil moisture.

What was the role of calcium in plant growth discussed in the video?

Calcium plays a crucial role in root development, cell wall structure, and overall plant growth, influencing the plant's ability to resist diseases.

What are the symptoms of magnesium deficiency in plants as observed in the survey?

Magnesium deficiency leads to chlorosis between leaf veins, where the leaf becomes pale yellow, followed by necrosis and leaf drop, especially in older leaves.

Where was the magnesium deficiency survey conducted?

The magnesium deficiency survey was conducted on a farm in Waikandis village, Tanjung Senang district, Bandar Lampung, Lampung province, with nearly 2 hectares of crops.

What fertilizers were used in the magnesium deficiency survey?

The fertilizers used included organic manure before planting, and chemical fertilizers such as urea were applied 5 and 10 days after planting.

What are the effects of potassium deficiency in papaya plants as observed in the video?

Potassium deficiency in papaya plants causes yellowing at the edges and tips of older leaves, followed by scorching at the leaf tips, and eventually leaf drying and death.

How is potassium applied to papaya plants to address deficiency?

Potassium is applied by burying the fertilizer beside the plants before planting and sometimes spreading it around each plant in the field.

What are the symptoms of nitrogen deficiency observed in vegetables like kangkung and bayam?

Symptoms of nitrogen deficiency include yellowing of the middle and tip portions of leaves, slow plant growth, stunted plants, and small, pale leaves that eventually turn yellow and wilt.

How is nitrogen deficiency addressed in the observed vegetables?

Nitrogen deficiency is addressed by using organic manure and chemical fertilizers such as urea, applied at specific times after planting using a broadcasting technique.
