Experiment Background
|
Cotton is globally considered as one of the most important commercial crops. Being a cash crop, it is grown worldwide for the purpose of oil, lint, and feed for animals. About 30 million hectares of fertile land is engaged in cotton cultivation in almost 70 different countries of the world. China is the world’s largest cotton producer and consumer, with an average lint yield of 14.38 g m−2 during 2013 followed by the US, India, and Pakistan. Due to its indeterminate growth habit, cotton exhibits morphological adaptation, such as modifying the canopy arrangement with phosphorus (P) application. The morphological adaptations in terms of light capture, sink to source relationship, and photoassimilates distribution, are the main reasons of enhancing seed cotton yield. For the last two decades, cotton yield per unit area remained stagnant in spite of the introduction of new high yielding cultivars. Utilization of mineral fertilizers is sought as an effective strategy to improve soil nutrient and boost cotton yield.
The use of increased fertilization has influenced the crop production over the last several years because of its effect on soil nutritional status and fertility characteristics. Phosphate fertilizer is central to crop productivity with a higher P requirement that is not in competition with soil P, especially at sub-optimal level compared with other nutrients. Phosphorus is very important in crop production after nitrogen (N); however, its resources are limited worldwide. The P application improves root architecture by increasing length, width, and diameter of root. Hence, P uptake by the plants is predominantly controlled by the availability and acquisition of P. Therefore, the P deficiency inhibits cotton growth and development by declining the biomass accumulation, leading to lower seed cotton yield.
