| What happens to the chillies crop if zinc is not replenished periodically? | not replenished periodically, the crop is prone to suffer from zinc deficiency severely | Chillies: The chillies crop has high affinity for zinc nutrition and hence large amount of zinc is taken up by the plant. If zinc is not replenished periodically, the crop is prone to suffer from zinc deficiency severely. The entire foliage of the crop will be reduced in size with interveinal chlorosis, when zinc is in short supply and the plant will present a stunted growth. | 133 | definition | 1.000 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | If zinc is not replenished periodically, the crop is prone to suffer from zinc deficiency severely. | 5 | page=5,block=0 | 0.850 | valid |
| What is the characteristic symptom caused by the blockage of vascular bundles in plants? | characterized by the tapering of truck towards the crown, the fronds will become smaller, rigid and erect | The onset of this disorder is brought about by blockage of vascular bundles which may lead to disruption in the translocation process. The typical symptom is characterized by the tapering of truck towards the crown, the fronds will become smaller, rigid and erect. The outer fronds will first show yellowing and drop off. | 158 | definition | 1.000 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | The typical symptom is characterized by the tapering of truck towards the crown, the fronds will become smaller, rigid and erect. | 5 | page=5,block=0 | 0.850 | valid |
| What does the term hen and chicken disorder refer to in grapes? | The presence of small sized fruits and large sized fruits in the same bunch | deficient in those elements. Copper and zinc are antagonistic when sprayed together. It is also observed that combined spray may cause tip burning of leaves in the absence of continuous stirring of spray fluid. It is, therefore, best to spray different micronutrients which are deficient individually rather than in combination based on leaf analysis. Grapes: The presence of small sized fruits and large sized fruits in the same bunch is known as hen and chicken disorder. The fruits are sour in taste. The symptoms include death of growing tips, leaf fall and brittleness of young shoots. The leaves may be deformed with interveinal chlorosis spreading from margins to inwards and this is particularly evident after the fruiting. Spraying of 0.2% boric acid a week before bloom and another at full bloom control the disorder effectively. | 360 | definition | 1.000 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | Grapes: The presence of small sized fruits and large sized fruits in the same bunch is known as hen and chicken disorder. | 7 | page=7,block=0 | ||
| What function does iron serve in the growth of citrus plants? | acts as a catalyst in chlorophyll synthesis | reported. Iron deficiency is comparatively very rare in banana plantations. foliar spray of 0.2 –0.5 % ferrous sulphate checks the disorder effectively. The recent researches suggest that iron deficiency in banana can be identified using chlorophyll fluorescence. Fe deficiency decrease the ratio of variable fluorescence to maximum fluorescence as observed from fluorescence induction curves indicating the involvement of Fe in both chlorophyll biosynthesis as well as in components of phosphorylation. Citrus: The element acts as a catalyst in chlorophyll synthesis. The deficiency of iron causes network of green veins against a light green or yellow background in leaves followed by bronzing of leaves. Grapes: The leaves turn yellow (chlorosis) during iron deficiency and the entire shoot become yellow to yellowish green under extreme conditions. | 524 | definition | 1.000 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | Citrus: The element acts as a catalyst in chlorophyll synthesis. | 2 | page=2,block=0 | 0.700 | |
| What term is used for nutrient elements needed in relatively small amounts? | micro or minor nutrients or trace elements | Tamil Nadu Agricultural University, Coimbatore – 641 003 The nutrient elements which are required comparatively in small quantities are called as micro or minor nutrients or trace elements. Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants. The requirement of micronutrients (boron, iron, copper, zinc, manganese, chloride and molybdenum) is only in traces, which is partly met from the soil or through chemical fertilizer or through other sources. The major causes for micronutrient deficiencies are intensified agricultural practices, unbalanced fertilizer application including NPK, depletion of nutrients and no replenishment. Horticultural crops suffer widely by zinc deficiency followed by boron, manganese, copper, iron (mostly induced) and Mo deficiencies. | 146 | definition | 1.000 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | Tamil Nadu Agricultural University, Coimbatore – 641 003 The nutrient elements which are required comparatively in small quantities are called as micro or minor nutrients or trace elements. | 1 | |||
| What is Iron deficiency? | a problem of high pH calcareous soils and is often described as lime induced chlorosis | Iron deficiency is rarely caused through insufficient iron in the soil but usually because it is rendered unavailable for the uptake by alkaline soil conditions or an excess of manganese or phosphorous. Iron deficiency is a problem of high pH calcareous soils and is often described as lime induced chlorosis. Custard apples are relatively sensitive suffering from iron deficiency while other crops such as bananas are usually not affected much. | 222 | definition | 0.980 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | Iron deficiency is a problem of high pH calcareous soils and is often described as lime induced chlorosis. | 1 | page=1,block=2 | 0.850 | valid |
| What is boron required for in plants? | cell division and development in the growth regions of the plant near the tips of shoots and roots. | Peas: Leaves are narrow, pointed and curled in wards. Yellow mottling on the lamina started from the base of the midrib and move upwards. Poor pod set and seed development. 3. BORON Boron is much required for cell division and development in the growth regions of the plant near the tips of shoots and roots. It also affects sugar transport and appears to be associated with some of the functions of calcium. Boron affects pollination and the development of viable seeds which in turn affect the normal development of fruit. A shortage of boron also causes cracking and distorted growth in fruit. Boron does not easily move around the plant and therefore the effects of deficiency appears first, and are usually most acute in young tissues, growing points, root tips, young leaves and developing fruit. | 209 | definition | 0.980 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | BORON Boron is much required for cell division and development in the growth regions of the plant near the tips of shoots and roots.

| What is lime induced chlorosis? | a problem of high pH calcareous soils | Iron deficiency is rarely caused through insufficient iron in the soil but usually because it is rendered unavailable for the uptake by alkaline soil conditions or an excess of manganese or phosphorous. Iron deficiency is a problem of high pH calcareous soils and is often described as lime induced chlorosis. Custard apples are relatively sensitive suffering from iron deficiency while other crops such as bananas are usually not affected much. This sensitivity appears to be related to crop’s poor ability to absorb or utilise iron. The common deficiency symptoms include development of light green chlorosis of all the tissues between the veins. A distinctive pattern results from the network formed by the midrib and veins, which remain green for example, custard apples. | 222 | definition | 0.980 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | Iron deficiency is a problem of high pH calcareous soils and is often described as lime induced chlorosis. | 1 | page=1,block=2 | 0.700 | valid |
| What are the effects of deficiency in tomato plants? | retardation in growth, curling of leaf upwards and inwards with severe scorching | Die back of twigs, slits on the bark and multiple bud development resembling witch’s broom are often witnessed under acute deficiency. Tomato: The deficiency leads to retardation in growth, curling of leaf upwards and inwards with severe scorching. The first symptom of copper deficiency is overall grey green colour followed by chlorosis of lower leaves. | 167 | relationship | 0.970 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | Tomato: The deficiency leads to retardation in growth, curling of leaf upwards and inwards with severe scorching. | 8 | page=8,block=0 | 0.800 | valid |
| Why are Papaya: The fruits of boron deficient papaya deformed and bumpy? | the irregular fertilization and development of seeds within the fruit | The size and quality of guava fruit can be increased greatly by foliar application of borax 1% and potassium chloride 3%. Papaya: The fruits of boron deficient papaya are deformed and bumpy due to the irregular fertilization and development of seeds within the fruit. Ripening is uneven and the developing fruit secrete pinkish white to brown latex. | 197 | relationship | 0.970 | https://agritech.tnau.ac.in/agriculture/pdf/Micronutrients%20for%20horticultural%20crops.pdf | Papaya: The fruits of boron deficient papaya are deformed and bumpy due to the irregular fertilization and development of seeds within the fruit. | 7 | page=7,block=0 | 0.800 | valid |
