Delta Agri Liquid Potassium: This product combines the two nutrients, Phosphorus and Potassium, as shown below:
Percentage of nutrient % (W/V): K2O: 45. / P2O5: 2
Each nutrient possesses important functions in plant development.
Potassium (K): Potassium is associated with the movement of water, nutrients and carbohydrates in plant tissue. It is involved with enzyme activation within the plant, which affects protein, starch and adenosine triphosphate (ATP) production. The production of ATP can regulate the rate of photosynthesis.
Phosphorus (P): Phosphorus is an essential element that is classified as a macronutrient. One of its main roles in living organisms is to transfer energy. Organic compounds that contain P transfer energy from one reaction to another within cells. Adequate P availability in plants stimulates early plant growth and hastens maturity.
Beit Alpha Cucumber: A Middle Eastern cucumber that is smooth and blocky with dark green skin. The flesh is crunchy, and the skin is mild, removing the necessity of peeling. It is usually picked small at 5 to 6" long. It can be used for pickling or sliced in salads. It is one of the most important cultivations for greenhouse plants in Iran by more than 6300 Ha planted area in the country.
The largest provinces by area for greenhouse cucumbers in Iran respectively are: Tehran (2246.5 Ha), Kerman (1885.8 ha), and Yazd (1330.5 ha).
Powdery mildew: The first sign of powdery mildew is pale yellow spots on leaves.
White powdery spots can form on both upper and lower leaf surfaces, and quickly expand into large blotches (see Pic 01 below.) When powdery mildew infects the majority of the foliage, the plant weakens and the fruit ripens prematurely.
Trial Method: Used the treatment at the fruit setting stage as foliar and following up the results in two evaluations: the first stage at 7 days after the foliar, and the second stage 14 days following the foliar.
Our treatments were divided accordingly: POT = Delta Agri Liquid Potassium, NOB = Control, UNT = Untreated.
Our parameters were to see indications of mature fruit in the plant in addition to detecting resistance to powdery mildew within the designated timeframe.
Results: The number of mature fruits in each harvest in Delta Agri Liquid Potassium was significantly higher than those of the Untreated and Control. In addition, the POT showcased higher stability than the Control group, as displayed in Chart 1.
Chart 2 portrays the powdery mildew (PM) resistance for each group, indicating a significantly higher resistance in the treated group (POT) than that of the Untreated (POT, Control, and Untreated, respectively).
On December 14, 2021, after a hiatus that lasted two years due to the Covid-19 Pandemic, DPN held its annual gathering in Parsian Azadi Hotel. The meeting highlighted DPN’s “commitment” to its core values despite the prevailing ongoing situation. Tokens of appreciation were offered to employees with over 5 and 10 years of experience as seniors, stressing their valuable contribution to the company as part of its commitment to excellence and constant employees growth and improvement.
In the context of developing its human capital, DPN held a technical training session for all its agricultural engineers on December 14, 2021, followed by another Advanced Negotiation skills Workshop targeting the Sales and Commercial team on the 15th and 16th. The gatherings reflected DPN’s commitment to excellence and constant improvement.
Blossom End Rot or in brevity BER is a physiological problem caused by lack of Calcium in the plant, Generally when the tomatoes’ fruit get rotting in the bottom it’s a sign of Blossom end rot, This is a common problem in the some plants like Tomato, Pepper, Eggplant and Squash, in this case the bottom tissue of the fruits get rotting, deformed and the fruit color get changes (brown or black), thus It has directly affects the fruit’s quality and overall yield of the plant. Cause of Blossom end rot The main cause of BER is the lack of Calcium in the plant, the lack of Calcium may be to due to the low amount of Calcium in the soil, the ability of the plant to absorb it, or the set of factors that have an effect on the absorption, The first one is related to the amount of Calcium, the second one is related to the plant, the last one is from the environment that the plants are faced to, Control and Prevention: The use of tolerant varieties can help reduce the occurrence of this disorder, Application of Calcium fertilizers before planting and in the plant establishment reduces the possibility of incidence of BER, Have an accurate irrigation schedule and avoid watering too much and too little can help to the plant to absorb the Calcium, Use mulches to provide the soil moisture to the plant especially in the dry periods, It can help to prevent this problem, Because blossom-end rot is caused by a calcium deficiency don’t tempt to fertilize your plants more, in most cases, there is already sufficient calcium in the soil but the plants just cannot absorb enough of it. Over fertilization is also harmful, and having too much nitrogen, magnesium, and potassium in the soil can actually make BER worse. Try to keep the soil PH in the range of 6.5 because in this range the most nutrients can be uptake by the plants,
