Abstract
A field experiment was conducted at the Agricultural farm of the Agricultural
Chemistry Department, Hajee Mohammad Danesh Science and Technology
University, Dinajpur, during the period from September to December, 2015 to
study the effect of different levels of benzylaminopurine on morphophysiological, yield and yield characters of chinigura rice cultiver. Results
showed that the morpho-physiological, yield and yield attributes were
significantly different among the levels of BAP. The plant height, leaf length,
leaf breadth, leaf number per plant, flag leaf chlorophyll content, tiller number
hill-1
, panicle length, panicle number hill-1
, 1000-grain weight, grain yield (t
ha-1
) , biological yield and harvest index were increased markedly due to the
application of BAP. The highest number of effective tiller, grain number
panicle-1
, grain yield (t ha-1
) , flag leaf Mg content , biological yield , and
harvest index were obtained from 100 ppm BAP spraying at vegetative and
pre-flowering stages. The highest yield of chinigura rice was 2.35 ton ha-1
due to the application of 100 ppm BAP which was statistically similar with
150 ppm BAP , where as other levels and controlled condition had less
pronounced effect on the growth and yield components of chinigura rice. Plant
growth regulators promote the growth and yield of rice varieties which might
be an alternative eco-friendly tool to rice production.
Description
Rice is the world’s most important food grain since nearly one half of the
population of the world use rice as their main food. In major Asian countries
rice consumption will increase faster than the population growth. Rice is one
of the most cultivated cereals in all over the world (Golshani et al., 2010) and
the demand for rice will increase dramatically because of the steady increase in
population (Liu et al., 2012). Crop intensification and higher yields are the
only way to bridge the increasing gap between food production and
consumption in densely populated tropical Asia, because there is little new
land available for rice cultivation (Chauhan et al., 1985).
The journey of rice around the world has been slow, but once it took root it
stayed and became a major agriculture and economic product for the people. In
the Indian subcontinent more than a quarter of the cultivated land is given to
rice. It is a very essential part of the daily meal in the southern and eastern
parts of India.
