Abstract
To prevent environmental pollution, promote ecological restoration and impart production sustainability in biomass crops, optimization of mineral fertilization regimes is strategically required under changing climatic scenarios. There exist research gaps regarding optimal use of nitrogen (N), phosphorous (P) and potassium (K) fertilizers for the fertilizer-responsive cultivars of forage legumes like cowpea under decreasing soil fertility in semi-arid regions. Therefore, a multi-year field experiment was executed to study yield attributes, green and dry matter yields along with nutritional quality attributes of forage cowpea. The treatments were comprised of different N-P-K levels viz. F 0 = (0-0-0), F 1 = (150-0-0 kg·ha -1 ), F 2 = (150-100-0 kg·ha -1 ) and F 3 = (150-100-100 kg·ha -1 ). The findings revealed that F 3 fertilization regime surpassed rest of treatments by recording the maximum plant population, plant height, leaf area index, plants fresh and dry weights, which led to the highest green forage yield (73% and 5.8% higher than control and following treatment of F 2 , respectively). For dry matter yield, all fertilization regimes performed better than control, however those were statistically at par to each other. Moreover, F 3 treatment exhibited 4.4% and 1.6% higher crude protein and ether extractable fat respectively, compared to the following treatment of F 2 treatment that remained at par with F 3 for total ash content. Contrastingly, the control treatment remained superior by giving the minimum crude fiber content which could be attributed to dwarf plants produced in the absence of fertilizers because stem length tends to contribute the major portion of fiber content in cowpea. Thus, 150-100-100 kg ·ha -1 N-P-K might be recommended to cowpea growers for boosting biomass productivity and nutritional quality, however further field investigations need to assess the impact of these fertilization regimes on biological N fixation process and solar radiation capture by cowpea plants under irrigated and dry semi-arid conditions.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
