African oil palm (Elaeis guineensis Jacq.) is a bulk feeder of nutrients. In this study, we aimed at devising strategies for efficient nutrient management in the plantations Krishna River basin located Andhra Pradesh, India by assessing soil fertility status, establishing optimal leaf concentrations and identifying yield restrictive total, 67 were surveyed from area 2020, samples collected anal...

A 3, NPK lime factorial experiment is used as a means of testing both soil and leaf norms for sugarcane obtained by the Diagnosis and Recommendation Integrated System (DRIS) developed by Beaufils. ,Soil and leaf samples were taken from the experiment when the cane was 3, 6, 12 and 18 months old respectively and analysed for a number of essential plant nutrients. The results show that these norm...

Domain Resource Integrated System (DRIS) is introduced in this paper. DRIS is a hierarchical distributed Internet information retrieval system. This system will solve some bottleneck problems such as long update interval, poor coverage in current web search system. DRIS will build the information retrieval infrastructure of Internet, but not a commercial search engine. The protocol series of DR...

Abstract Improper nutrient management reduces the yield and affects status of crops. This study aimed to diagnose nutrients limitation in maize. A three-year multi-location (348 sites) experiments were conducted randomized block design analyse for maize production under conventional fertilizer recommendation system Nigeria using DRIS, identify soil factors that influence DRIS indices random for...
