Abstract:
The most important role of nitrogen in the plant is its presences in the structure of protein,
nitrogen is also found in chlorophyll, the green colouring matter of leaves. Chlorophyll enables
the plant to transfer energy from sunlight by photosynthesis. Next to nitrogen, phosphorus is the
most important nutrient needed by a wheat crop for plant development starting when wheat is
just a seedling and continuing all the way to maturity. Adequate potassium results in superior
quality of the whole plant due to improved efficiency of photosynthesis, increased resistance to
some diseases, and greater water use efficiency, stronger wheat straw and assists in grain filling.
Plant hormones play a pivotal role in the regulation of plant growth and development. However,
their role becomes more crucial under stress because they also act as stress signaling molecules,
response determiners, and regulators. Thus, phytohormones are considered the most critical
endogenous substances because they regulate many physiological and developmental processes.
A field experiment was conducted during 2019-20 to study the effect of different weed control
methods and mulching on growth and yield of chickpea at Brahmanand Post Graduate College,
Rath district Hamirpur Uttar Pradesh. As a consequence it was found that highest plant height
(cm), fresh weight plant-1
(g), dry weight plant-1
(g) and number of functional leaves plant-1 was
found in application of 120:60:40 (N:P:K) ratio of fertilizer level and this growth put forth
maximum value of yield attributing characters and finally yield viz. number of effective tillers, length of ear (cm) test weight (g) and grain yield (q ha-1
) followed by other reducing fertilizer
levels i.e. 100:50:30, 80:40:20, and control. Application of 1.5 kg ha-1 was increased
significantly these all growth, yield and yield attributing characters in wheat crop as seed
treatment before sowing. The minimum value was recorded with control plots, while, the wheat
yield also decreased beyond the dose of 1.5 kg ha-1
application of Gibberlic acid when compared
with application of 2.0 kg ha-1 Gibberlic acid. |
