“…However, the differences between increamental level of RDF from 100 to 125 and from 125 to 150 % were not found to be significant as also reported by Deshpande et al (2014) andRawal et al (2015). Cotton, being an inderminate crop, the positive effect of applied fertilizers can be realized to the level to have the synchronized growth of vegetative and reproductive parts.…”

Fertilizer and moisture availability affect various physiological and growth processes and are key factors in controlling productivity and yield of cotton crop. Two-year experiment (kharif 2012 and 2013) was conducted to evaluate the effects of different fertilizer levels on growth, yield, water and partial factor productivity of fertilizers of furrow irrigated raised bed (FIRB) planted transgenic cotton in semi-arid region of north-west India. The fertilization treatment was based on different ratios of N, P2O5 and K2O. Four fertilizer treatments were designed including 75%, 100%, 125% and 150% of recommended rates with N 175, P2O5 60 and K2O 60 kg/ha. Yield components were measured. Partial factor productivity of fertilizer (PFP), water productivity and economics were calculated. Compared to conventional method of sowing, FIRB planted cotton produced significantly higher yield components, viz. sympods and bolls/plant and boll weight. The seed cotton yield of FIRB planted crop increased by 10.3% in 2012 and 11.2% in 2013. This method of sowing also resulted in higher PFP for individual nutrients, i.e. N, P and K as well as for the total nutrients, i.e. N, P and K. It also provided higher water productivity, net benefit and B:C. Non-Bt genotypes did not show any marked diffence in terms of yield, WP and PFP of nutrients applied over Bt, however, was better in terms of net benefit and B:C. The PFP decreased with the increase of fertilization rates. With 75% RDF, the PFPN during the respective two crop seasons was 14.02 and 12.98 kg seed cotton/kg applied N and decreased to 7.05 and 6.98 with 150% RDF. The corresponding values of PFPP or K were 40.90 and 37.88 which decreased to 21.89 and 20.31 kg seed cotton/kg applied P or K. Similarly, the PFP N,P and K was 8.33 and 7.72 and the corresponding vlaues with 150% RDF were 4.45 and 4.41 kg seed cotton per kg applied N, P and K. Under semi-arid conditions, to achieve higher productivity hybrid cotton (Gossypium hirsutum L.) be planted under FIRB system fertilized with N -175, P2O5-60 and K2O-60 kg/ha.

“…Crop growth, nitrogen and potassium uptake, total chlorophyll content, and dry matter yield of cotton plant are significantly enhanced by phosphorous [69]. The application of phosphorous leads to increased phosphorous uptake and content in leaf, stem, and reproductive parts such as seeds [70]. Phosphorous has a stimulating effect on number of flower buds and bolls per plant as well as is essential for cell division.…”

Cotton (Gossypium hirsutum L.) is a vital fiber crop that is being cultivated under diverse climatic conditions across the globe. The demand for cotton and its by-products is increasing day by day due to more consumption of this fiber in the textile industry and the utilization of cotton seed as a source of edible oil. However, the average seed cotton yield in the world is below that of the potential yield of cultivars. The factors responsible for low yield includes shortage of approved seed, pest and disease attack, weed infestation, unwise use of nutrients, and the incidence of abiotic stresses (including drought, heat, and salinity). Among these, the abiotic stresses are a single major factor, which is responsible for reducing the yield now and will affect the productivity of cotton in future. In this scenario, it is necessary to adopt ways to improve the tolerance of cotton against abiotic stresses. The strategies for improving tolerance against abiotic stresses may include the wise use of macroand micronutrients, the use of osmoprotectants, the use of arbuscular mycorrhizal fungi, and the plant-growth promoting rhizobacteria.

“…Field experiments were conducted for three years during Kharif, 2009-2011 to study the effect of foliar application of nutrients (N, Mg, Fe, Zn, Mn and B) on growth and yield parameters of Bt cotton and results of pooled data indicated highest seed cotton yield with application of MgSO 4 1.0%+ ZnSO 4 0.5% (Singh et al, 2015). The field experiment on effect of fertilizer levels on nutrient availability and yield of cotton on Vertisol was conducted at Rahuri and found that the application of 100% RDF+1% MgSO 4 sprays recorded highest yield of Bt and non-Bt cotton hybrids (Deshpande et al, 2014). Shivamurthy and Biradar (2014) conducted an experiment at Dharwad in medium black soils and revealed that application of 1% solution of 19:19:19 water soluble fertilizers at 70, 90 and 110 DAS along with RDF+FYM+3 foliar sprays of 1% MgSO 4 +soil application of MgSO 4 @ 25 kg ha -1 recorded significantly higher number of bolls plant -1 and boll weight over RDF+FYM+ water spray.…”

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.
