Effect of bacteria as a biofertilizer associated with plastic mulch on the growth and economic value of sweet pepper [electronic resource]

Includes bibliographic reference

This research was carried out during 2019/2020 and 2020/2021 seasons, at the Experimental Station of the Central Laboratory
for Agricultural climate CLAC, A.R.C, Dokki, Giza. This experiment was done under a plastic greenhouse to investigate the growth,
fruit quality parameters and yield of sweet pepper plants grown under two different plastic mulch color and three different
cyanobacteria fertilizations. The plastic mulch treatments were transparent polyethylene and white polyethylene with 100 microns thickness.
Bare soil (uncovered soil) was used as a control. Transparent and white polyethylene was laid after the establishment of the double rows
(0.80 m width). Beds were manually installed to correspond to treatments and cyanobacteria fertilization treatments: cyanobacteria foliar fertilization,
cyanobacteria soil fertilization and cyanobacteria foliar with soil fertilization (spray+ Soil). Vegetative growth
(plant height, stem diameter, number of leaves/ plants, number of branches/ plants, leaves fresh weight and leaf area), as well as fruit yield
and quality (total yield, fruit length and fruit diameter), chemical contents (Nitrogen, Phosphorus, Potassium, Leaves dry matter% and Vitamin C)
of sweet pepper (Capsicum species) Gedeon F1 Hybrid. Obtained results revealed that using transparent plastic mulch with a combination of
cyanobacteria foliar and soil fertilization enhanced all vegetative growth measurements and increased all assayed chemical constituents of
plant leaves, as well as increasing total fruit yield and components.
