Explanation
Sodium benzoate is used as a preservative in processed tomato products. It helps inhibit the growth of microorganisms.
Correct Answer
Climacteric
Explanation
Tomato is a climacteric fruit/vegetable, meaning it continues to ripen after harvest, accompanied by a rise in respiration rate and ethylene production.
Correct Answer
Day Neutral Plant (DNP)
Explanation
Tomato is classified as a Day Neutral Plant (DNP), indicating its flowering is not significantly affected by day length. This allows it to be grown in different seasons.
Correct Answer
125-150 gm
Explanation
The recommended seed rate for hybrid tomato varieties is 125-150 grams per hectare. Normal varieties require a higher seed rate of 400-500 gm/ha.
Correct Answer
Flowering occurs at the top and each node
Explanation
Determinate tomato varieties have limited growth, and flowering occurs at the terminal bud (top) and at each node. They are typically grown in open fields and usually don't require staking.
Correct Answer
Flavor Saver
Explanation
Flavor Saver is renowned for its high storage capacity and was the first genetically modified tomato variety developed using biotechnology. It was developed by Calgene in 1994.
Correct Answer
Fruit Cracking
Explanation
Fruit cracking in tomatoes is often associated with Boron deficiency. Applying borax solution can help manage this disorder.
Correct Answer
Calcium
Explanation
Blossom End Rot (BER) is a physiological disorder in tomatoes caused by Calcium (Ca) deficiency. Spraying calcium chloride can help prevent it.
Correct Answer
Whitefly (Bemisia tabaci)
Explanation
The Leaf Curl disease in tomatoes, caused by a virus, is transmitted by the Whitefly (Bemisia tabaci). Whiteflies are common sucking pests in many crops.
Correct Answer
Alternaria solani
Explanation
Early Blight disease in tomatoes is caused by the fungus Alternaria solani. It affects leaves, stems, and fruits, causing characteristic target-like lesions.
Correct Answer
25 meters
Explanation
For certified tomato seed production, the recommended isolation distance is 25 meters. For foundation seed, it is 50 meters.
Correct Answer
Angurlata
Explanation
Angurlata is highlighted as a tomato variety suitable for growing in kitchen gardens. Kitchen garden varieties are often chosen for ease of growth and continuous yield.
Correct Answer
Fully ripening stage
Explanation
Tomatoes intended for processing (like making ketchup or paste) are harvested at the fully ripening stage. This stage ensures maximum color and flavor development.
Correct Answer
High temperature and excess nitrogen
Explanation
Puffiness, characterized by hollow cavities inside the fruit, is caused by factors like high temperature and excess nitrogen application. Proper environmental control and balanced fertilization are key.
Correct Answer
Tomatine
Explanation
Tomatine is a chemical compound found in tomatoes that exhibits fungal-resistant properties. It's a glycoalkaloid naturally present in the plant.
Correct Answer
Citric Acid
Explanation
Citric acid is the predominant acid found in tomatoes, contributing to their characteristic tangy taste. Acid content influences flavor and processing suitability.
Correct Answer
fresh market; Pear shape
Explanation
Punjab Chuara is a tomato variety characterized by its pear-shaped fruits and is considered suitable for processing. Fruit shape and firmness are important traits for processing varieties.
Correct Answer
Damping Off
Explanation
Damping Off, caused by fungi like Pythium and Phytophthora, is cited as the most dangerous disease affecting tomato seedlings in the nursery stage. It causes seedlings to collapse at the soil line.
Correct Answer
No true insect vector
Explanation
TMV is often spread mechanically. Seeds are the main factor in the long-distance transmission of ToMV.
Correct Answer
Boron and Zinc
Explanation
The document explicitly lists Boron and Zinc as essential micronutrients required by tomatoes. Deficiencies in these can lead to various growth issues and disorders.
Correct Answer
High temperature (more than 40°C)
Explanation
High temperatures, especially above 40°C, can cause Sun Scald, damaging exposed fruit surfaces. Providing adequate foliage cover helps prevent this.
Correct Answer

Explanation
Pythium aphanidermatum is a common soilborne pathogen that causes Damping off, especially in young seedlings. It leads to rotting of stem.
Correct Answer
Early Blight
Explanation
Alternaria solani causes Early blight, characterized by dark, concentric lesions on leaves and fruits. It can significantly reduce yield.
Correct Answer
Leaf Curl disease
Explanation
Whiteflies are the vector for the Leaf Curl virus, which causes severe leaf distortion and stunting. Controlling whitefly populations is crucial.
Correct Answer
