Cotton is an important fibre and cash crop in India, contributing significantly to the country's industrial and agricultural economies. It provides the textile industry with its main raw material (cotton fibre). Cotton in India is a direct source of income for 6 million farmers, while the cotton trade and processing employs approximately 40-50 million people. Agriculture in the twenty-first century has encountered numerous hurdles in meeting the expanding population's food and fibre needs. Humans will confront greater challenges in meeting their requirements as the population grows to reach nine billion by 2050. A field experiment was conducted in Farmer’s Field at Jayapuram Village, Natrampalli Taluk in Thirupathur District during Aug-Jan (2021-22) to investigate the effect of soil application of NPK fertilizers, Zn-enriched compost and foliar spray of ZnO2 and NAA on enhancement of cotton yield and quality in sandy loam soil. Fertilizers (N: P2O5: K2O) were sprayed at the appropriate dose (60:30:30 kg ha-1) using Urea, SSP, and MOP. Zn-enriched compost (Zn-EC) was treated at 1.0 t ha-1 as a basal one week before sowing. As per treatment. ZnO2 at 0.1% was applied twice during the vegetative and blooming periods of the crop. The treatment included spraying NAA at 40 ppm twice during flowering and boll formation. Cotton cv. Sabari was cultivated as a test crop using suggested cultural methods. The highest seed cotton yield of 1813.73 kg ha-1 was observed with application of 75% RDF + Zn EC @ 1.0 t ha-1 + ZnO2 @ 0.1%+ NAA @ 40 ppm (T9). the present investigation clearly concluded that 75% RDF + Zn EC @ 1.0 t ha-1 + ZnO2 @ 0.1%+ NAA @ 40 ppm (T9) was the best treatment for enhancing growth, yield, quality and nutrient uptake by cotton cv. Sabari. The study examined how different treatments affected growth, yield characteristics, quality, and soil health.

“…However, Pinho et al, (2010) showed reduced gs and transpiration in B-deficit conditions resulted in overheating of coconut leaflets. Seed cotton yield: Beneficial effects of boron application @ 1.0 kg/ha and 2.0 kg /ha have been reported to increase grain yields in wheat (Ahmed et al, 2018). B-doses of 0.75 and1.50 kg ha -1 led to an increase of 22 and 52% in number of bolls plant -1 (Fig.…”

“…Crop growth parameters: Crop growth rate (CGR) refers to dry matter produced by a crop in certain amount of time although it is affected by a variety of environmental and internal factors adequate levels of available micronutrients is one of them (Ahmed et al, 2018). Boron is an essential micronutrient required by plants for normal growth and development and its insufficiency results in growth impairments such as reduced plant height and biomass (Zhao & Oosterhuis, 2003).…”

The productivity of arable crops is greatly impacted by imbalanced nutrient management. The deficiency of one or more mineral nutrients can cause substantial reduction in crop yields. Of the micronutrients, the deficiency of boron affects the yield potential of cotton to the greatest extent. This study was carried out to quantify the boron nutritional requirement of cotton. The treatments included three boron levels (0.0, 0.75 and 1.50 kg B ha -1 ) and two application regimes (soil and soil plus foliar). Foliar application was done at 30, 60 and 90 days after sowing during peak growth stages. The results revealed that application of 1.50 kg B ha -1 along with foliar sprays increases crop growth rate (CGR) and net assimilation rate (NAR) by 15% and 31% respectively. While, the membrane leakage was reduced by 35% by addition of 1.50 kg B ha -1 , chlorophyll a and b contents improved by 2% and 5% through combined application of boron via soil and foliar spray. The water-useefficiency was enhanced by 35% by application of B-fertilizer through soil as well foliar spray. Gas exchange parameters, i.e.net photosynthetic rate, transpiration rate and stomatal conductance increased by 66%, 47% and 62% respectively after application of B-fertilizer and there was a significant increase in number of bolls per plant, boll weight and an ultimate improvement in final seed cotton yield of 16%.
