Abstract
A field study titled "Effect of planting methods and meteorological approach based
irrigation scheduling on yield and water use efficiency of Aloe (Aloe barbadensis)" was conducted
from 2021 to 2023 at the MAP section, Research Area, Department of Genetics & Plant Breeding of
CCS Haryana Agricultural University, Hisar. The experiment included three types of planting methods
(Raised bed, Flat bed, and Ridge and furrow) and four levels of irrigation scheduling (Rainfed (Control),
IW30mm/CPE=0.6, IW30mm/CPE=0.8, IW30mm/CPE=1) arranged in a factorial randomized block design
with three replications.
The results of the study revealed significant effects of both planting methods and irrigation
scheduling on the growth, yield, yield attributes, and economic returns of aloe. Among the planting
methods, raised bed demonstrated superior performance with significantly higher leaf yield (91.59 t/ha),
gel yield (48.33 t/ha), net returns (₹256595/ha), and B:C (2.28) compared to ridge and furrow and flat
bed. This was attributed to the increased number of harvestable leaves (14.80) associated with the raised
bed. Regarding irrigation scheduling, IW30mm/CPE=0.8 closely followed by IW30mm/CPE=0.6 resulted in
significantly higher leaf yield (88.28 t/ha) and gel yield (46.98 t/ha) compared to the control, with an
increment of 32.05 t/ha and 20.77 t/ha, respectively. Additionally, IW30mm/CPE=0.6 exhibited higher net
returns (₹232460/ha) and B:C (2.16), surpassing the control by ₹97435 and 0.23, respectively. Based on
these findings, it is advised to adopt a raised bed planting method along with irrigation scheduling
IW30mm/CPE=0.8 to achieve higher yields and IW30mm/CPE=0.6 to improve economic returns and
enhanced water productivity in aloe.
