Evaluating the Interactive Impact of Nitrogen Levels and Cultivars on Yield Traits, Nitrogen use Efficiency, Water use Efficiency and Benefit Cost Ratio of Ratoon Rice in Punjab, Pakistan
Ratooning of rice (Oryza sativa L.) is process of obtaining grain from tillers that grow from crop stubbles that have already been harvested. Ratooning has gained attention since it has a potential for obtaining yield with conventional techniques. Field experiment was conducted during 2021–2022 at the research farm, Institute of Agronomy, Bahauddin Zakariya University Multan, Punjab, Pakistan. The response of various nitrogen (N) levels (0, 25, 50, 75, and 100 kg ha− 1) was studied on the growth and yield of three rice cultivars (Guard Lp-02, Guard Lp-18, and Super Fine) grown as ratoon rice. In cultivars, Guard Lp-02 and Guard Lp-18 were hybrid but Super Fine was a non-hybrid cultivar. The hybrid cultivars showed a significant response to N levels. The cultivar Guard Lp-18 with higher level of N 100 kg ha− 1 resulted in more plant height, total tillers, fertile tiller, panicle length, and biological yield while the higher number of branches and grains per panicle, 1000-grain weight, and grain yield was achieved by Guard Lp-18 with the application of 75 kg N ha− 1. Maximum agronomic nitrogen use efficiency (ANUE) and economic nitrogen use efficiency (ENUE) was observed at cultivar Guard Lp-18 with N level of 50 kg ha− 1. Likewise, water use efficiency (WUE) was recorded maximum at cultivar Guard Lp-18 with N level 75 kg ha− 1. The highest gross income, net income, and benefit cost ratio (BCR) were noted at 75 kg N ha− 1 among all cultivars but Guard Lp-18 with 75 kg N ha− 1 respond better in ratoon rice. Among rice cultivars, hybrid rice performed better and out yielded non-hybrid cultivars in ratoon rice. The findings of this study revealed that growing ratoon rice will be helpful for increasing farm income; enhancing resources use efficiency and ensuring food security under prevailing agro-climatic conditions of Punjab, Pakistan.
期刊介绍：
IJPP publishes original research papers and review papers related to physiology, ecology and production of field crops and forages at field, farm and landscape level. Preferred topics are: (1) yield gap in cropping systems: estimation, causes and closing measures, (2) ecological intensification of plant production, (3) improvement of water and nutrients management in plant production systems, (4) environmental impact of plant production, (5) climate change and plant production, and (6) responses of plant communities to extreme weather conditions.
Please note that IJPP does not publish papers with a background in genetics and plant breeding, plant molecular biology, plant biotechnology, as well as soil science, meteorology, product process and post-harvest management unless they are strongly related to plant production under field conditions.
Papers based on limited data or of local importance, and results from routine experiments will not normally be considered for publication. Field experiments should include at least two years and/or two environments. Papers on plants other than field crops and forages, and papers based on controlled-environment experiments will not be considered.
