Abstract:
The study was carried out at Agriculture research station, Seetha Eliya,
from February to May 2022 to find the effect of red onion peel and garlic peel fertilizer
mixture on the growth and yield performance of lettuce. The pot experiment was laid
out in a completely randomized design with nine treatment and four replicates. Powder
forms of onion and garlic peel fertilizer were used in the 1:1 weight ratio. Nine different
powder mixture; T1 (control) – only ½ recommended compost, T2 – ½ recommended
compost + 2g powder, T3- ½ recommended compost + 4g powder, T4 – ½
recommended compost + 6g powder, T5 – ½ recommended compost + 8g powder, T6
– only 2g powder, T7 – only 4g powder, T8 – only 6g powder, T9 – only 8g powder
were used. Powder form was applied as basal and after 1st and 3rd weeks from
transplanting. Plant growth parameters; leaf length, width, plant height, number of plant
and yield were measured. Data were analyzed in ANOVA one way method using
Minitab software. Among all nine treatments, T2 was showed significantly better fresh
weight (324.79±14.03) and number of leaves (24.00±1.00) than others. T3, T4, T5
were showed good growth and yield performance. Therefore, onion garlic peel fertilizer
improved lettuce yield. The use of organic onion garlic peel fertilizer mixture used as a
plant growth booster is inexpensive, environmentally safe, and low-cost technology to
improve the yields of small farmers.
