| What issue is commonly associated with high pH calcareous soils? | 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 | 1.000 | 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 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 | 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? | 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 | 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 term is used for nutrient elements needed in very 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 | 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 | page=1,block=2 | 0.700 | valid |
| What role does boron play in plant growth? | Boron is much required for 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. | 182 | definition | 1.000 | BORON Boron is much required for cell division and development in the growth regions of the plant near the tips of shoots and roots. | 6 | page=6,block=0 | 0.700 | valid |
| What is hen and chicken disorder 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 | 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 | 0.700 | valid |
| What is the role of molybdenum in plants? | functions in enzyme nitrate reductase which is responsible for reduction of nitrate to nitrite during N assimilation | Cauliflower: The deficiency symptom appears in the older leaves with grey interveinal mottling and necrotic areas. Yound leaves retain their normal colour but become chlorotic between veins, which gradually spread to older leaves. Peas: Marsh spots (Minute brown spots) on the older leaves during flowering which become yellow mottled in the interveinal areas. Flowers shed after fading and seed development is affected. 6. MOLYBDENUM Molybdenum functions in enzyme nitrate reductase which is responsible for reduction of nitrate to nitrite during N assimilation in plants. Although molybdenum deficiency is observed in many soils and pasture legumes, vegetables and occasionally cereals, it is very rare in fruit crops. There are few reports that molybdenum deficiency called as yellow spot is observed in citrus. | 446 | definition | 1.000 | MOLYBDENUM Molybdenum functions in enzyme nitrate reductase which is responsible for reduction of nitrate to nitrite during N assimilation in plants. | 10 | page=10,block=0 | 0.700 | valid |
| What is the role of zinc in plants? | Zinc is important for the formation and activity of chlorophyll and in the functioning of several enzymes and the growth hormone, auxin. | It commonly affects banana, custard apple and mangoes. Problems often appear in spring when crops are growing quickly but have difficulty in absorbing nutrients from cold soil. Zinc is important for the formation and activity of chlorophyll and in the functioning of several enzymes and the growth hormone, auxin. The severe stunting of leaves and shoots, which is so typical of zinc deficient crops is a consequence of low auxin levels in tissue. Young leaves are usually the most affected and are small, narrow, chlorotic and often rosetted due to failure of the shoot to elongate. Bloom spikes are small, deformed and drooping. In young pine apple plants, zinc deficiency is indicated by the young heart leaves bunching together and then tilting horizontally. This condition is commonly called crook neck. | 177 | definition | 1.000 | Problems often appear in spring when crops are growing quickly but have difficulty in absorbing nutrients from cold soil.

| What is pencil point disease in coconut palms? | a physiological disorder affecting coconut palms to a great extent. | 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. Foliar application of zinc sulphate @ 500 g and urea @ 100 g dissolved in 100 lit of water along with 100 ml soap solution is to be given two to three times at an interval of 20 days depending upon the extent of severity. Foliar application has to be supplemented with soil application of zinc sulphate @ 8 kg/acre is given basally during last ploughing of the field. Coconut: Pencil point disease is a physiological disorder affecting coconut palms to a great extent. 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. | 558 | definition | 1.000 | Coconut: Pencil point disease is a physiological disorder affecting coconut palms to a great extent.
