Abstract
This study aimed to determine the effect of cultivar, nitrogen fertilizer rate and plant density on sorghum growth performance under different environmental conditions. A field experiment was carried out at two different locations of North-West province during 2016/17 and 2017/18 planting seasons. The experiment was laid out as a split split plot arrangement fitted into a randomized complete block design with four replications. The main plot factors were higher plant density (33 333 plants/ha) and lower plant density (22 222 plants/ha). The subplot factors consisted of nitrogen fertilizer rates of 0, 100 and 150 kg/ha. The sub-sub plot factors included two sorghum cultivars, PAN 8625 and PAN 8816. The measured growth parameters were plant height, stem diameter, leaves per plant, leaf chlorophyll content and leaf area index. Sorghum fertilised with 100 kg N/ha had a significantly taller plant of 94.07 cm than sorghum fertilised with 0 and 150 kg N/ha at 51 DAP. During 2016/17 planting season, sorghum cultivar PAN 8625 had a significantly higher number of 13.29 leaves than PAN 8816 at 51 DAP. Sorghum cultivar PAN 8625 also had a significantly higher number of 12.71 leaves than PAN 8816 at 74 DAP. Sorghum growth was enhanced by application of 100 kg N/ha. In this study, sorghum cultivar PAN 8625 is recommended to farmers due to its superior growth performance.
期刊介绍：
Interciencia is the monthly multidisciplinary publication of the INTERCIENCIA Association. It is dedicated to stimulate scientific research, its humanitarian use and the study of its social context, specially in Latin America and the Caribbean and to promote communication between the scientific and technological communities of the Americas.
Interciencia has been published uninterruptedly since 1976. Its Founding Director, Marcel Roche (endocrinologist and sociologist of science) was editor until 2008, and thereafter Miguel Laufer (neurobiologist) has been in charge. It has been included since 1978 in the Science Citation Index and other international indexes, and since 2008 it maintains an open access electronic version with material from 2005 onwards.
The priority areas of the journal, without exclusion of other areas, are Agronomy, Arid Lands, Food and Nutrition, Biotechnology, Ecology and Environment, Energy, Innovation and Technology Transfer, Marine Resources, Non-renewable Resources, Science Education, Science Policy, Study and Sociology of Science, and Tropical Forests.
Interciencia publishes in Spanish, Portuguese and English research and review articles, communications and essays, all of which are subjected to peer review. Additionally, it includes non-refereed sections such as Editorial, Letters to the Editor, Open Town Hall, Book Reviews and Upcoming Events.
All the material submitted to the journal for publication and accepted by the Editorial Committee in view of its quality and pertinence is subjected to review by peer specialists in the corresponding fields of knowledge. Neither the INTERCIENCIA Association, nor the journal or the institutions to which the authors belong carry responsibility for the contents. Signing authors are responsible for the material published under their names.
