Abstract
Polyhalite is a natural mineral which contains potassium (K2O, 14%), sulphur (SO3, 48%), calcium (CaO, 17%) and magnesium (MgO, 6%). It is used as fertilizer for high value crops. Soil fertility, selection of fertilizer sources and application practices are all crucial factors in maximizing mineral nutrition during the cropping season. With an increasing demand for fertilizer, polyhalite was identified as a potassium source for crops. In view of this context, a present experimental work was conducted during 2021-22 at farmer’s field, Arachalur, Erode district, Tamil Nadu, India to study the influence of polyhalite on growth attributes, yield attributes and yield of sugarcane var. Co 11015. The experiment was conducted in sandy loam soil laid out in randomized block design with 10 treatments replicated thrice. The recommended dose of nitrogen and phosphorus was applied uniformly to all treatments. The potassium was applied in two sources, muriate of potash (MOP) and polyalite in different ratios and levels except control. The results of the field experiment revealed that sugarcane significantly responded to the application of two potassium sources and levels. The maximum values of growth attributes like plant height, number of leaves per stalk, leaf area index, leaf chlorophyll content, yield attributes and yield like, number of internodes per stalk, length of internode per millable cane, length of millable cane, diameter of millable cane, single cane weight, number of tillers per plant, number of millable cane, cane yield and sugar yield were recorded with application of RDF (NP alone) + 150% K (169.5 kg K2O/ha) as polyhalite (T8). The lowest respond was found in the treatment T1, which received RDF (NP alone).
期刊介绍：
The Research on Crops is a peer-reviewed journal publishing original research papers, review articles and short communications in English on all basic and applied aspects of crop sciences, agricultural water management, agro-climatology, agroforestry, agronomy, crop production, crop protection, cropping systems, food science & technology, genetics & plant breeding, horticulture, plant & soil science, plant biotechnology, plant nutrition, post-harvest management of crops, seed science, soil management & tillage, vegetables, weed science, agricultural engineering, agri-business, agricultural economics and extension, etc. The aim of the journal is to provide a forum for the scientific community to publish their latest research findings.
The manuscripts submitted for publication should not contain data older than 4 years on the date of submission.
The articles submitted for publication in this journal should not be submitted elsewhere simultaneously for publication in another journal. These should not carry any copyright material without prior permission of copyright holder.
The articles should present a complete picture of the investigation made and should not be split into parts.
There is no prescribed limit regarding the number of pages in case of full-length articles. However, the authors are advised to keep the length of their articles from 4 to 10 full printed pages of the journal.
The articles should be divided into the sub-sections: ABSTRACT, INTRODUCTION, MATERIALS AND METHODS, RESULTS AND DISCUSSION, CONCLUSIONS, and REFERENCES. Tables and figures should be appended separately at the end.
