“…Firstly, the promotional effects of N application is more easily observed than P. Secondly, cotton producers can have easier access to N than to P and K [10]. In recent years, China begins to pay more and more attention to the environmental problems caused by the overuse of N and the deficiency of P and K and cotton producers are encouraged to adopt a balanced application of N, P, and K [11].…”

Combined application of nitrogen (N), phosphorus (P), and potassium (K) is a valuable practice to improve the growth and physiological activities of cotton, especially during a boll setting. The main purpose of this research was to investigate the effects of the different combined ratios of nitrogen (N), phosphorus (P), and K (potassium) on morpho-physiological activities of Bacillus thuringiensis (Bt) cotton genotypes Siza 1 and Sikang 1 during the cotton boll development stage. A two-year (2016–2017) field experiment was performed in which the total amount of combined N, P, and K were applied at different levels, B1 = 150 N, 0 P2O5, and 0 K2O kg ha−1 (control), B2 = 150 N, 45 P2O5, and 90 K2O kg ha−1, B3 = 150 N, 90 P2O5, and 135 K2O kg ha−1, and B4 = 150 N, 135 P2O5, and 180 K2O kg ha−1. Results revealed that combined application of N, P, and K significantly increased boll length by 5.8% and 2.3%, fresh boll weight by 12.2% and 16.4%, dry lint weight by 15.2% and 1.7%, number of seeds boll−1 by 15.2% and 2.5% as well as dry boll shell weight by 11.0% and 4.9% as compared with the treatment without P and K (1:0:0) across two growing seasons. Furthermore, superoxide dismutase activity was improved by 2.3% and 15.6% and soluble protein by 5.1% and 14.1% as compared with the control, respectively. Our study indicated that combined application of N, P, and K at appropriate ratios enhanced morpho-physiological activities (boll length, boll width, boll weight, protein content, sugar content, and superoxide dismutase) of cotton during boll development and generally the ratio of 150:135:180 considerably performed best amongst all treatments during two growing seasons in this study.

“…The prevalence of high temperatures (45-48ºC) during the cotton-growing season, especially in the early and mid-season, limits potential yield of the cotton crop in this part of the world (Ali, Afzal, Ahmad, & Muhammad, 2009;Usman et al, 2009;Ali et al, 2010;2013a;2013b;Amin et al, 2017a;2017b). It is commonly understood that flowers appearing during July and August cannot produce good quality lint due to the poor opening of harvestable bolls under the prevalence of high temperatures during this growth period (Dong, Zhang, Tang, Li, & Li, 2005a;Dong, Li, Tang, Li, & Zhang, 2005b;Ali et al, 2010;Tariq et al, 2017).…”

ABSTRACT. Due to high temperatures in arid regions, cotton crop emergence and early establishment of seedlings are adversely affected. Field studies were undertaken to quantify the effects of transplantation of cotton (Gossypium hirsutum L.) seedlings during the early part of the growing season (March) and crop season (May) for potential realization of cotton productivity under the harsh weather of the southern part of Punjab province, Pakistan. Treatments, consisting of (a) two planting dates (March and May), and (b) two sowing methods (transplanting of seedlings and direct seeding), were arranged in a randomized complete-block design with four replications. Results showed that transplanting seedlings improved the productivity of cotton by 14.2% over direct seeding. Productivity was also increased substantially (34.8%) by planting during March over May sowing. The practice of planting cotton by transplanting seedlings and early sowing could be successfully adapted in areas where high temperatures coincide with the May planting and peak blooming periods in different cotton growing areas.Keywords: heat stress; irrigated arid environment; planting techniques; planting time.Aumento da produtividade do algodão por meio de transplante de mudas e semeadura precoce RESUMO. Altas temperaturas, em torno de 48ºC, prevalecem durante os meses de maio na parte do sul da província de Punjab, no Paquistão. A esta temperatura a emergência da colheita de algodão e o estabelecimento precoce da plântula são adversamente afetados. Estudos de campo foram realizados para quantificar os efeitos do transplante de mudas de algodão (Gossypium hirsutum L.) durante a primeira parte da estação de crescimento (março) e da safra (maio) para a realização potencial da produtividade do algodão sob condições adversas da parte sul do Punjab Província-Paquistão. Os tratamentos, consistindo em (a) duas datas de plantio (março e maio), e (b) dois métodos de semeadura (transplante de mudas e semeadura direta), foram dispostos em delineamento em blocos ao acaso com quatro repetições. Os resultados mostraram que o transplante de mudas melhorou a produtividade do algodão em 14,2% em relação à semeadura direta. A produtividade também aumentou substancialmente (34,8%) com o plantio em março sobre a semeadura de maio. A prática de plantio de algodão por transplante de mudas e sua semeadura precoce poderia ser adaptada com sucesso, onde a alta temperatura coincide com o tempo de plantio durante o mês de maio e períodos de florescimento máximo em diferentes áreas de cultivo de algodão.Palavras-chave: estresse por calor; ambiente árido irrigado; técnicas de plantio; tempo de plantio.

“…Lime content of soil greatly affects P availability (Abbaszadeh-Dahaji et al 2020;Delgado et al 2002). Amin et al (2017) suggested 57 kg P 2 O 5 ha −1 for obtaining maximum yield, while Hussain et al (2004) proposed 75-100 kg P 2 O 5 ha −1 for wheat. Even 90 kg P 2 O 5 ha −1 which exhibited about 90% of grain yield could be considered adequate.…”

Crop response to phosphorous (P) application is often erratic in most soil types in the world. In alkaline calcareous soils, P retention and mobilization take place due to precipitation and adsorption. P adsorption isotherms are the powerful tools for assessing optimum P levels for different crops and soils. Laboratory and field studies were carried out to evaluate P sorption capacity in a highly calcareous soil and corresponding fertilizer levels for yielding 0.1 to 1.0 mg P L −1 of soil solution. Although Freundlich adsorption isotherm model showed a better fit than Langmuir model, P fertilizer levels used in the field, ranging from 20 to 150 kg P 2 O 5 ha −1 , were based on Langmuir model to yield the estimated P solution. Moreover, nitrogen (N) and potassium (K) were applied at the rates of 120 and 60 kg ha −1 as urea and potassium sulfate (K 2 SO 4), respectively, in a basal treatment at the time of sowing. Grains per spike, 1000-grain weight, grain yield, spike length, and biological yield were increased as the level of P increased, but the non-significant differences among 90, 100, and 120 kg P 2 O 5 ha −1 for most of the above parameters suggested that the former rate could be the maximum level for wheat fertilization in the calcareous soil. Similarly, plant N, P, and K were increased with application of P, but non-significant differences were observed from doses 90 to 120 kg P 2 O 5 ha −1. Moreover, the rate of 90 kg P 2 O 5 ha −1 could yield 0.6 mg P L −1 of soil solution as per Langmuir adsorption isotherm model, while as per Freundlich model, this value could reach only 0.3-0.4 mg P L −1 , which is close to the published literature. It is concluded that Freundlich adsorption isotherm is more suitable to be used for the calculation of phosphatic fertilizer rate and its adsorption capacity in the given soil than Langmuir adsorption isotherm.
