Effect of Organic Fertilizer on Growth and Yield Performance of Lettuce
growing using organic fertilizer is becoming increasingly accepted by most of
the agricultural industry due to the persistent of conventional fertilizers
which have huge effects of pesticides doses being consumed by humans. The
environments are also being destroyed by the excess use of inorganic
fertilizers. Organically produced vegetables are being perceived as healthier
and quality as compared to the conventional produced crops.
Organically grown foods are
perceived as better quality, healthier and more nutritious than conventional
counterparts (Warman and Havard, 1997). Lettuce (Lactuca sativa) is
an annual crop of the daisy family. It is mostly grown as a leafy vegetable.
research will be conducted to verify the application of efficacy of different
rate of organic fertilizers on Lettuce (Letuca sativa). There would be five (5)
treatments in total and these would be made up of blank control, organic and
inorganic fertilizers. The organic control treatment may be compost applied
with three different rates (chicken manure tea, cattle manure and sheep
manure). The rest of the treatments will be inorganic fertilizer and blank control.
At the end of the investigation, the vegetative parameters that will be
measured are height, weight, and leaf diameter, stem and leaf number
research will be conducted under field conditions at the European University of
Lefke farm site. Before planting will begin, some soil samples will be taken to
analyze and check the amount of NPK and other properties. The experiment will
be laid out in Randomized Completely Block Design (RCBD) and the treatments are
expected to be replicated three (3) times. Lettuce (Letuca sativa) the best
cultivars will be used for the proposed study plan.
The compost will be prepared by
Passively Aerated Window Method (FAO, 2003)
