“…yield was obtained by foliar application of water which increased number of days from sowing to the first flower appearance (DFF) and number of opened bolls/plant (DFB) in both seasons. These results are confirmed with Dwivedi et al (2014), El-Sayed et al (2015), Elansary et al (2016), Emara (2016), Yadav et al (2016), Van Oosten et al (2017) and More et al (2018) who reported that using Algal extracts or potassium silicate or micronutrients improved the growth and yield of plants under water stress.…”

Two field experiments were carried out at the Farm of Nubaria Agricultural Research Station, Agricultural Research Center (ARC), Giza, Egypt, representing the newly reclaimed desert land of North West, Egypt in Nubaria, which located at 46 Km South West of Alexandria city to study the effect of irrigation regimes and NPK fertilization, earliness parameters, seed cotton yield, its components of Egyptian cotton (Gossypium barbadense L.) cultivar Giza 94 was used which represent long staple Egyptian cotton category in the two summer growing seasons of 2017 and 2018. The experimental design was a split-split plot with four replications, where the irrigation regime treatments were allocated to the main plots and the sub-main plots included NPK fertilization, while foliar application treatments were taken place in sub-sub plots, where irrigation regimes were irrigation at 50% depletion of available soil moisture. (I1), irrigation at 70% depletion of available soil moisture (I2) and irrigation at 90% depletion of available soil moisture (I3). While NPK-fertilizer rates were 100% of NPK recommended doses (75 kg N, 31 P 2 O 5 and 48 K 2 O/fad.), 75% of NPK recommended doses (56.3 kg N, 23.3 P 2 O 5 and 36 K 2 O/fad.) and 50% of NPK recommended doses (37.5 kg N, 15.5 P 2 O 5 and 24 K 2 O/fad.). Foliar application treatments were control (water), potassium silicate (two times at the rate of 1 kg/fad., before flowering and two weeks later), extractable mixed of algae, amino acids and micronutrients (two times at the rate of 1 L/fad., before flowering and two weeks later).The results revealed that growth and yield attributes of cotton were affected by water stress under NPK fertilization and foliar application, in this respect the highest value of growth, yield characters were achieved under irrigation regime (50% depletion of available soil moisture) and recommended dose of NPK and foliar application of Algal extracts + amino acids + micronutrient) under Nubaria conditions.

“…Raj and Chandrasekar (2019) reported that seed treatment with nano ZnO in combination with foliar application of nano ZnO @ 1000 ppm recorded significantly higher seed cotton yield than recommended practices. Significantly higher yield attributing character number of picked boll plant -1 , seed cotton yield plant, seed cotton yield kg ha -1 were reported by application of 125% RDF+foliar spraying of 0.5% Zinc+0.2% Boron) twice during flowering and boll development stage (More et al, 2018). A field experiment conducted by Santhosh et al (2016) revealed that soil application of MgSO 4 and three foliar sprays of MgSO 4 (1%)+KNO 3 (2%) recorded maximum seed cotton as compared to control (water spray).…”

“…Raj and Chandrasekar (2019) reported that higher plant height, number of monopodial branches, sympodial branches, LAI, LAD and SPAD chlorophyll meter value than other concentrations due to foliar application of nano ZnO @ 1000 ppm. More et al (2018) reported that application of 125% RDF+foliar spraying of 0.5% Zinc+0.2% Boron twice during flowering (60 DAS) and boll development stage (80 DAS) recorded significantly maximum growth attributes but it was at par with the 125% RDF + foliar spraying of 0.2% of Boron and 125% RDF +foliar spraying 0.5% Zinc. A field experiment was conducted at Raichur to evaluate the effect of nutrient management practices on leaf reddening on Bt cotton and results revealed that 3 foliar sprays of MgSO 4 +KNO 3 , MgSO 4 +19:19:19 NPK along with soil application of MgSO 4 during flowering, boll formation and boll development stages, reduced the LRI by 18.7 and 16.2% at 135 DAS and 12.7 and 11.5% at harvest stages, respectively as compared with control (Santhosh et al, 2015).Reddening in Bt cotton leaves was reduced by 30 to 40 % with foliar application of urea @ 2% + DAP @ 2%+MgSO 4 @ 1% at boll formation stage (CICR, 2009).…”

Secondary and micronutrients are essential elements that are used by plants in small quantities. Yield and quality of agricultural products increased with secondary and micronutrients application, therefore human and animal health is protected.. Secondary (Ca, Mg, S) and micronutrients especially Zn, B are essential for higher productivity of cotton. Magnesium is essential for the production of the green pigment in chlorophyll, which is the driving force for photosynthesis. It is also essential for the metabolism of carbohydrates (sugars), for cell division and protein formation. Zinc is an element directly affects yield and quality because of functions such as activity in biological membrane stability, enzyme activation ability and auxin synthesis, while, boron plays an essential role in the development and growth of new cells in the growing meristem and also required for protein synthesis where nitrogen and carbohydrates are converted into protein. This article reviews the influence of Mg, Zn and B application on yield and quality aspects of Bt cotton.

“…Cotton plants need B during flowering and boll development stages; B stimulates pollen germination and pollen tube growth and causes successful fruit setting (Emara et al, 2015). More et al (2018) revealed the positive effects of spraying with B on growth, fruit retention, and yield components of cotton. Kassem et al (2009), Hamoda (2012), and Karademir & Karadmir (2020) illustrated that foliar application of B gives the highest values in leaves content of N, P, K, Mg, B, Fe, Mn, and Zn and significantly increases the seed cotton yield compared to control.…”

W ATER deficiency is the most common abiotic stress in cotton production in Egypt.Although, cotton plants react strongly to soil moisture, water-deficit conditions during squaring and flowering stages diminish plant growth and productivity. The experiment was conducted to evaluate the physiological response of three Egyptian cotton cultivars (Giza 94, 96 and 97), under irrigation intervals (normal and severe water-deficit conditions) and with spraying with growth inducers [calcium(Ca)-boron(B) and mixed amino acids] and their interactions on the leaves chemical constituents and yield components during the 2020 and 2021 seasons. The experiment design was a split-split plot with three replicates. The main plots included three cotton cultivars, the subplots included two irrigation intervals and the subsubplots included spraying with growth inducers at squaring and flowering stages (400ppm). The results revealed that the performance of the three cotton cultivars was significantly different in chemical constituents and yield components via their different genetic potentials, with the best results registered by Giza 97 compared to Giza 94 and 96. Water-deficit conditions significantly reduced leaves pigment content and all yield components, but significantly improved all osmolyte compounds (total soluble sugars, total phenol, total free amino acids, free proline and total antioxidant capacity) compared to normal conditions. Spraying with growth inducers significantly enhanced the chemical constituents and yield components compared to untreated plants in relation to their positive effects in improving photosynthesis, sugar biosynthesis and all cotton cultivar yields. Giza 97 sprayed with Ca-B under normal conditions recorded the best results compared to other treatments.
