Evaluating Different Densities Of Lettuce (Lactuca Sativa L) With Varying Levels Of Feeding Regimes On Tilapia Fish (Oreochromis Niloticus L) In Aquaponics System, Ahmed Salem Mohammed Suhail Alkaabi

Theses

Aquaponics uses waste generated by fish as plant nutrients within a re-circulating system that returns clean water back to the fish. The purpose of this study was to cultivate the high quality of lettuce (Lactuca sativa L.) and Tilapia (Oreochromis niloticus L.) production in an integrated aquaponic system with recirculating aquaculture system in the UAE climatic condition on three different densities and feeding regimes. An experiment was conducted under greenhouse conditions in the United Arab Emirates in 2016 (from April to August). The evaluation of the production was based on three parameters viz., head of the …

Determination Of The Ideal Plant Density Of Tomato Solanum Lycopersicum Under An Aquaponic Production System With Tilapia Oreochromis Aureus Under Uae Conditions, Mohamed Ahmed Al Dhanhani

Theses

Aquaponics is an agricultural system that saves water and fertilization and offers a way of growing plants without soil pest infestation or pesticide residues. This system ensures the production of hazardous chemical free food for humans. This system also ensures sustainability by creating a natural relationship between fish and plants and makes gardening more productive and economical.

Aquaponics system is a dynamic ecosystem that can be integrated to achieve food security through the production of fish and vegetables without the intervention of fertilizers.

The focus of this study is optimizing planting density of tomato in an aquaponics system; with assess …

Determining Growth Characteristics And Control Programs For Nealley's Sprangletop (Leptochloa Nealleyi Vasey), Trace Buck

LSU Master's Theses

ABSTRACT

Research was conducted at the LSU AgCenter Dean Lee Research and Extension center near Alexandria, La in 2016 and 2017 to evaluate the growth characteristics and control of Nealley’s sprangletop. Nealley’s sprangletop is a relatively new weed with little research available to understand its growth habit and effective control strategies.

Nealley’s sprangletop undergoes a more drastic height increase of 212 to 742 mm, 4 to 6 WAE than Amazon sprangletop 377 to 612 mm in the same time frame. Averaged across harvest interval tiller and leaf number of Nealley’s sprangletop was approximately 50 and 40% less than Amazon sprangletop. …
