Horticulture MCQ Question and Answer | Agriculture MCQ Question

TSS is total soluble solids. It is equivalent to the percentage of a reference sugar solution.
The TSS is mainly composed of sugars (fructose). Minimum sugar values in melon fruits need to be 8%. Melons with a sugar content of 10 - 12% have, as defined by US grading standards, a 'very good eating quality'. They will also transport well.
TSS of ripe muskmelon lies between 11 - 17%.

Brinjal is also known as Eggplant. Brinjal is the Indian name of this vegetable, also called by the same name in Singapore, Malaysia and South Africa.
It is called Eggplant in the US, Canada and Australia.
Its scientific name is Solanum melongena belongs to the nightshade family i.e. Solanaceae. It is grown worldwide for its edible fruit.

The pointed gourd is the dioecious plant among the following options.
A dioecious plant has either male or female flowers, not both. For dioecious plants to reproduce, a male plant must be near a female plant so that pollinators can do their work.
Trichosanthes dioica, also known as the pointed gourd is a vine plant in the family Cucurbitaceae, similar to cucumber and squash, though unlike those it is perennial.
It is a dioecious (male and female plants) vine (creeper) plant with heart-shaped leaves (cordate) and is grown on a trellis. The fruits are green with white or no stripes. Size can vary from small and round to thick and long 2 to 6 inches. It thrives well under a hot to moderately warm and humid climate.

The temperature range that is suitable for the development of red colour in tomato fruits is 18° - 25°C.
The red colour of tomato fruit is due to the carotenoid known as Lycopene. And it develops at a definite temperature range. However, the formation of lycopene is inhibited when the temperature of the fruits exceeds 30 degrees Celcius. High temperature affects the fruit set and development. Also, the plants cannot withstand low temperatures, frost and high humidity.

Potato Witches Broom is caused by MLOs.
Potato witch broom is a plant disease that occurs as an abnormal brushlike cluster of dwarfed weak shoots arising at or near the same point.
Witches broom are caused by a phytoplasma transmitted by several species of leafhopper and within the potato plant seed pieces.
Leaves started rolling up and have yellow margins. Plants are dwarfed in the field.

Cluster bean commonly known as guar has come to be recognized as one of the most important commercial crops of arid and semi-arid regions. It is a drought-hardy leguminous crop because of its deep tap rooting system and has a high capacity to recover from water stress.
Cluster bean contains a mucilaginous substance that is Mannogalacton. The seed of cluster bean contains about 30 - 33% gum in the endosperm. The discovery of the Mannogalacton gum in the endosperm in 1948, led to this hitherto insignificant plant gaining importance as an industrial crop.

Exclusion of moisture is the permanent method of preservation of fruits and vegetables.
Drying is the method of preservation of fruits and vegetables usually practiced in homes. Drying is done to remove moisture from the fruits and vegetables that reduce the chances of rotting and ant microbial activity. Thus it enables us to keep it and used it later whenever required in off season also.

The premature setting of the jam is due to Low TSS. This problem arises due to the presence of low total soluble solids and high pectin content.
A high percentage of total soluble solids makes the jam sticky and gummy. This can be prevented by the addition of a sufficient amount of citric acid, pectin, or both.

From the given options Carrot gives higher protein recovery per unit area.
Raw carrot have 88% water, 9% carbohydrates, 0.9% protein, 2.8% dietary fiber, 1% ash and 0.2% Fat.
Carrot is one of the important root vegetables rich in bioactive compounds like carotenoids and dietary fibers with appreciable levels of several other functional components having significant health-promoting properties.
The consumption of carrots and their products is increasing steadily due to their recognition as an important source of natural antioxidants having anticancer activity.

Embryo abortion by extreme temperatures or by soil supersaturation is a typical symptom of a physiological disorder in tomatoes that is known as Puffiness.
Puffiness in tomatoes results from incomplete pollination, fertilization, or seed development often as a result of cool temperatures that negatively impact fertilization.
High nitrogen and low potassium can also lead to puffiness.
