#Penetration agents’ improve absorption of a herbicide by solubilizing waxy cuticle (lipoidal part) of cell wall or the membrane of plant tissues.

#”Woman’, first observed that plant come up from seed.

#Other seeds” shall include seed and seed-like structures of any plant species other than that of pure seed.

#20-25 days old seedlings are ready for transplanting of short duration varieties of rice.

#A herbicide move faster in young plants than in old ones.

#A seed, strictly speaking, is an embryo, a living organism embedded in the supporting or the food storage tissue.

#A significant quantity of plant available boron in soils is held in the organic matter fraction.

#A useful function of chlorine is the contributing to turgor of leaves and other plant parts.

#Absorption rates of H,PO, by plant roots can be described by Michaelis-Menten kinetics.

#Acclimation is the process by which plants become adapted to an unfavourable set of climatic conditions.

#According to Bray’s nutrient mobility concept crop yields obey the percentage sufficiency concept of Mitscherlich for such elements as phosphorus and potassium while are relatively immobile in the soil.

#According to Liebig’s law of the minimum, even if all but one of the essential elements be present, the absence of that one will render the crop barren”

#Acid forming nitrogenous fertilizers are expected to augment the uptake of both native and supplements zinc.

#Acrolein is contact aquatic herbicide.

#Active ingredient in is that part of the formulate product that that is principally responsible for herbicidal effects.

#Active ion absorption is thought to take place by metabolically produced carriers which transfer the lons across otherwise impassable barriers.

#Additive effect refers to the total effect of a combination which is equal to the sum of the effects of the component independently

#Aging refers to the accumulation of degenerative changes which ultimately results in death or the failure or the seed to germinate.

#Agricultural drought is a period of four consecutive weeks from May to mid-October or six consecutive weeks during rest of the year.

#Agriculture today is not merely production oriented, but has become sustainable agribusiness.
Ammonium is the preferred nitrogen source since energy will be saved when it is used instead of nitrate in synthesis of protein.

#An excellent example of the use of plant analysis in crop production is the crop logging carried out for sugarcane in Hawaii.

#An extremely wide N/S ratio say 20:1 or more could restrict organic matter breakdown, if the soil was already deficient in this element.

#Any compact heavy texture soil that is calcareous and basic in reaction is potentially iron deficient.

#Any physical or chemical treatment that weakens the seed coat is called scarification.

#Application of phosphorus especially on phosphorus deficient soils considerably reduces the risk of winter damage.

#At sea, tornadoes are known as waterspouts.

#Awned varieties of wheat and rice are better suited under drought condition than awnless.

#Azospirillum is the nitrogen fixing bacterium on root surfaces of plants like maize, millet, rice and wheat etc..

#Azotobacter and Clostridium are asymbiotic nitrogen fixers.

#Bacillius megatherium var. phosphaticum (Phosphobacterin) increases the plant availability of native and applied soil phosphorus.

#Band placement reduces the surface of contact between the soil and fertilizer with a consequent reduction in phosphorus fixation.

(Agronomy One liner)

#Because of immobility of copper in soil, it is supplied to plant roots mainly by root interception.

#Boron alters the phytohormonal activity with an accumulation of auxin in plants deficient in this nutrient.

#Boron is the only non-metal among the micronutrient elements having the constant valence of +3 coupled with a very small ionic radius.
