“…Crop growth and yield were affected by nutrient deficiencies. Zinc is an element directly affecting the yield and quality because of its role in activity of biological membrane stability, enzyme activation ability and auxin synthesis [2]. Boron plays an essential role in the development and growth of new cells in the growing meristem and also pollen tube growth and increases pollination and seed development [2].…”

A field experiment was conducted to study the influence of potassium fertilization (K @0, K @60 and K @ 90 kg ha-1) and secondary (Magnesium) and micro nutrients (Zinc and Boron) on growth and yield parameters and yield of cotton hybrid Bt (MRC 7201 BGII) at Hyderabad, India during 2015-16 and 2016-17. The experiment was laid out in a split plot design with three main treatments and eight sub treatments and replicated thrice. Among the potassium levels, K @ 90 kg ha-1 recorded significantly higher plant height (76.86, 106.13 cm), number of seeds per boll (30.3, 30.9), seed cotton yield (1941, 2591 kg ha-1) and stalk yield (1967, 2755 kg ha-1) during 2015 and 2016. Among secondary (Magnesium) and micro nutrients (Zinc and Boron), Mg1%Zn0.5%B0.1% recorded highest plant height (74.65, 102.80 cm), dry weight (221.39, 243.54 g), number of seeds per boll (29.27, 29.87), seed cotton yield (1941, 2591 kg ha-1) and stalk yield (1967, 2755 kg ha-1) during 2015 and 2016.

“…On the other hand, zinc (Zn) and boron (B) are elements directly influence yield and quality due to their functions. Zn affects 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 required for protein synthesis where nitrogen and carbohydrates are transformed into protein (Swetha et al, 2020). B is an important element for plants and single nonmetal among plant micronutrients.…”

A field experiment was carried out through the two growing seasons of 2021 and 2022 to find out the impact of the addition of humic acid and sulphur at soil and foliar spraying with chelated Zn and/or chelated B in addition to their interactions on cotton cultivar Super Giza 94 (Gossypium barbadense L.) grown under calcareous soil located at El-Nubaria Station Farm, Agricultural Research Center, Egypt. The layout of the experiment was a split plot design with three replications. The obtained results revealed that humic acid as well as a mixture of chelated Zn and chelated B increased numbers of monopodia and sympodia/plant, plant height at harvest, total fruiting points number/plant and total bolls number set/plant, bolls setting%, seed cotton yield /feddan, yield components and fiber length in both seasons. Bolls shedding% was decreased in this respect. Humic acid alone significantly improved fiber fineness and decreased the 1 st sympodium node. Similarly, a mixture of chelated Zn and chelated B significantly increased fiber strength. Using humic acid interacting with a mixture of chelated Zn and chelated B significantly increased numbers of monopodia and total bolls set/plant, yield of seed cotton/feddan, yield components, fiber fineness and strength in the two seasons of study. In addition, it increased bolls setting% and number of sympodia/plant only in the 1 st season. However, bolls shedding% was decreased. Addition of humic acid to the soil interacting with chelated Zn foliar spraying recorded taller plants. It could be concluded that using humic acid interacting with a mixture of chelated Zn and chelated B alleviated and counteracted harmful effects of calcareous soil in El-Nubaria region on cotton productivity of cultivar Super Giza 94.

Objective: The objective of this investigation was to determine the effects of different applications of magnesium (Mg) on yield, yield attributes, fiber quality traits, chlorophyll content, and normalized difference vegetative index in cotton. Material and Methods: In this study 7 different Mg applications were applied, and MAY 455 cotton cultivar and Magnesium Sulphate were used. Results: It was determined that seed cotton yield, number of nodes of first fruiting branches, number of vegetative branches, number of bolls, height/node ratio, boll weight, fiber strength, uniformity, elongation, and spinning consistency index were affected by magnesium applications. The highest value in terms of the number of bolls, number of vegetative branches and height/node ratio was observed with 200 cc/da Mg application at the squaring stage, while the highest seed cotton yield was recorded with 200 cc/da Mg at flowering stage and Mg application lead to increase 60 kg/da in seed cotton yield. The highest spinning consistency index and uniformity was obtained with 600 cc/da Mg application at the squaring stage, other quality traits were affected by different doses or application stages. Conclusion: Applying green parts during the squaring or flowering period may be advantageous since magnesium has a positive impact on the yield and certain fiber quality of cotton.
