Effect of phosphorus and potassium application in rabi sweet corn (Zea mays L. var. saccharata Sturt) under south Gujarat condition
Research Type
Departmental Trail
Experiment Background
The most common important essential macro nutrient for crop growth after nitrogen is phosphorus and it is needed in maize appreciable quantities. Phosphorus requirement is generally low as compare to nitrogen but its application is necessary for promoting root growth and development, early flowering and ripening. It is involved in a wide range of plant processes from permitting cell division to the development of a good root system and for ensuring timely and uniform ripening at the crop. It shows its deficiency mainly at the seedling stage, though it is needed most after flowering stage.
Potassium is taken up in large quantities by plants. It is highly mobile within plant vascular systems and plays an essential role in a number of metabolic functions. Over 60 enzymes require K for catalytic activity, some of which play a role in protein synthesis and sugar degradation. Water relations of plant cells rely on the rapid movement of K ions in order to maintain and regulate turgidity and stomatal control can be affected if K is deficient. Potassium also promotes the translocation of photosynthetic assimilates from leaves to grain through the phloem and demonstrated that both the rate at which grain fills and the period for which it fills can be increased by K fertilization. Application of potash increased vigour and disease resistance in plant, helps in protein production of plants, induced plum development of grain, improved quality of plant, helps in root developments and helps in formation and transformation of starch, sugar and oils. Keeping in this view, the present experiment was carried out.
