increase the income of farmers in the coming years in the harsh climatic condition specially
during summer in North India. According to FAO (2005), ramie plants per hectare can produce
up to 300 tons of fresh forage / year, equivalent to 42 tons of dry matter. Suryanah et al.,
(2018) also reported based on the research conducted till now, the best cutting age for the ramie
plant as a source of forage is at the age of 30 days.
Methodology
One trial in previously planted ramie (Boehmeria nivea) field was planned and designed for
accessing the seasonal growth performance and other related parameters during winter season
(December 2021), hot humid season (August, 2021) and hot dry season (April 2022) at ICAR
NDRI, Karnal field area. The month of April 2022 was marked as the hottest month in last 122
years and by chance the dates of trials fall in this duration hence the recorded data have
additional importance. Three years back the ramie plants were propagated by stem cuttings,
layering, division of parent root stalks or rhizome cutting 10 to 15 cm long and 15-20 cm deep
Suckers and planted in rows 100 to 120 cm apart, with individual plants spaced 30 to 60 cm
apart the rhizomes were planted on ridges to keep it safe from water logged situations. Under
experiment 40 lines of well grown ramie plants were harvested 4 inch above the ground level
in one day and from the very next day (1 st day of experiment), the recording of parameters like
total biomass per line in grams, plant height in centimeters, number of leafs per plant and
percent water content were recorded daily for each line for next 40 days continuously on same
time of the day during the experiment period in different seasons.
Results
The data recorded and its graphical presentation is given below. The seasonal comparison on
plant growth number of leafs cut plants individual bund weight and water content percent was
done. The plant growth (height in centimeter) was found to be highest during the month of
April 2022(hot dry season) followed by August 2021(hot humid season) and lowest plant
growth was recorded during December 2020-2021(winter season). During the trial of 40 days,
the plant height was maximum at 40 th day which was 38.39cm in winter, 141.8 cm in July (hot
season) and highest was in hot dry season, which indicates that ramie crop may be able to
survive in high temperature and low humidity zones with regular irrigation facilities.
The number of leafs per plant were highest during hot dry season as compared to winter and
hot humid season. During hot dry season, the percent increase in number of leafs plants was
lower as compared to hot dry season. The number of leafs remained 69.84% as compared to
average value of 100%, whereas it was 81.62% in hot humid season whereas highest
percentage number of leafs increased 148.3% as compared to the average scale of 100% that is
around 1.5 times more than the average value, which clearly indicates that the average leaf
