Growers urged to complete sunflower sowing

Punjab Agriculture Department (PAD) has warned the growers to immediately complete sunflower sowing as further delay will result in lower per acre yield. A spokesman of the Department said here on Monday that best time for spring plantation of sunflower in Southern Punjab including Multan, Bahawalpur and Dera Ghazi Khan Division is till February 10. While in Sahiwal, Faisalabad and Sargodha Division best time for sowing is till February 15 and for Lahore, Gujranwala and Rawalpindi Division the suitable time is till end of February. He further stated that the growers should adopt latest technology to get maximum per acre production.

What is Ebb and Flow Hydroponics and How Does it Work?

Ebb and flow hydroponics is a method of growing plants hydroponically that is known for its reliability, simplicity of operation and low cost of investment. Pots or a flood tray are filled with a grow media such as gravel, clay pellets, lava rock etc. These do not function like soil or add nutrition to the plants but will anchor the roots and will function as a temporary reserve of water and nutrients. The hydroponic solution floods the system four to six times a day and is allowed to drain away in between flood cycles.
With this system a water tight flood tray or pot, containing either clean gravel, clay pellets or lava rock is used as the rooting medium. The system is then periodically flooded for short periods of time (5 to 15 minutes) with a nutrient solution pumped from a reservoir. By placing the reservoir below the flood tray, with a over flow drain, the nutrient solution can drain back by gravity through the pump with the same line that supplied the water and nutrients during the flood cycle. Our favorite media is lava rock with this type of system. Lava rock drains quickly and traps air and will not leave a clay residue if using clay pellets, which can clog the water pump after time.

Aeration of an ebb and flood system is one of the most important things of the system. Let me explain, when the system floods it is in a deep water culture mode. Your reservoir may contain an air delivery system such as a air stone to keep the water saturated with oxygen and eliminate a pathogen problem. During the flood cycle the oxygenated air is pumped into the tray or bucket for 5 to 15 minutes. During this 5 to 15 minute period there is no additional air and oxygen being supplied to the tray or bucket. So even though you are now in deep water culture mode your plants are not receiving the amount of air and oxygen as if they were in a deep water culture system. The reason why is a deep water culture system has air constantly pumped into the reservoir 24 hours a day in which the roots are submerged. During the ebb cycle, or draining of the tray or bucket, air is now pulled down into the grow media supplying oxygen to the plants. At this point until the next flood cycle the roots again are being deprived of fresh air and oxygen.

Drawbacks to Ebb and flood hydroponic systems:
1. Pathogens in reservoir, flood tray or pot due to stagnated water during drain time which can contaminate the entire system due to the shared water source.
2. Limited amount of oxygen available during flooding of tray or pot.
3. Limited amount of oxygen available while in the ebb or drain stage.

Is there a solution to the problem above?  Ebb and flow hydroponic system to help eliminate the problems above. By adding Air Injection Technology at the very bottom of the media in your current flood tray or pot you will eliminate the drawbacks to a ebb and flood hydroponic system. You will also increase the plants growth rate and have healthier plants. 1. Pathogens in the flood tray or pot are eliminated because there is a constant supply of oxygen 24 hours a day weather in the flood stage or drain stage. 2. Constant supply of oxygen during the flood stage just like true deep water culture. 3. During the ebb or drain stage there is constant air being delivered to the plants roots 24 hours a day weather in the flood or drain stage. This will bring your current Ebb and flow hydroponics system up to date and will allow you to take full advantage of your ebb and flood hydroponics system at minimal cost.

DAAM win 3rd Position in Pakistan Nature Carnival at PAF museum

Overview:

WWF-Pakistan in collaboration with Horlicks Pakistan organised a fun-filled Nature Carnival at PAF Museum. The Nature Carnival attracted up to 30,000 individuals from various walks of life.
There were over 150 stalls set-up by schools, colleges and universities. The main competition revolved around 3D models set up by students of schools and universities. Expert judges including foresters, conservationists, and environmental historians amongst others graded the models.
Families, corporate and academia representatives including principals attended the carnival. Participants were engaged in eco-friendly games, puppet shows, lucky draw and other activities set up by WWF-Pakistan including pin the tail on the snow leopard and thematic art competitions.
Chief Guest at the event was famous Pakistani drama and film actress Atiqa Odho. She said that each and every one of us should start taking care of the things we need for our survival including forests, water and all our natural resources so that we can give a thriving planet to our children and their children.

DAAM win 3rd Position in Pakistan Nature Carnival at PAF museum:

Department of Agriculture and Agribusiness Management (DAAM) win third position under university category, DAAM represent Hydroponics model system for vegetable and fruit cultivation, hydroponics or soil-less farming system is one of the most discuss technology around the globe, hydroponics is the only solution to fulfill the requirement of world vegetable requirements.
