Studies on the Soil Nematode Diversity in Relation to the Soil Parameters from Sugarcane Fields of Aurangabad District Maharashtra State, India

Abstract

A survey was conducted from sugarcane fields at four completely different sampling sites like Paithan, Aurangabad, Phulambri and Khultabad taluka. During May-2016 -April-2017. To study the nematodes diversity and their correlation with the soil parameters soil samples was collected from the sugarcane root zones from the four completely different sugarcane fields. The Nematodes were extracted from collected soil samples by the Baermann's funnel technique. And also prepared the soil samples for testing the different soil parameters in the laboratory like Temperature, Moisture content, Water holding capacity, pH and electrical conductivity of the soil. The Nematodes were identified up to Generic level and the numbers of nematodes per 150grams of soil were determined. From all fields, eleven genera of nematodes were collected the collected nematodes belongs to the genus, Iotonchus, Dorylaimus, Dorylaimoides, Indodorylaimus, Xiphinema, Eudorylaimus, Axonchium, Longidorus, Hemicycliophora, Monhystera and Hoplolaimus. Among these, the seven genera were found from Paithan taluka which belongs to Dorylaimus, Dorylaimoides, Iotonchus, Xiphinema, Eudorylaimus, Hoplolaimus and Indodorylaimus. In Phulambri and Khultabad taluka also have same genera, however, in Aurangabad, another generas was additionally recorded i.e. Axonchium, Longidorus, Hemicycliophora and Monhystera. In this study co relationship between plant-parasitic nematodes and soil physicochemical parameters of sugarcane soil. Is carried out and also studied the effect of soil parameters on the nematode diversity. The details are discussed in the text.

The phytonematodes species on sugarcane plants (Saccharum officinarum L.) at Subang Sugar Factory PT PG Rajawali II, West Java

“…Phytonematodes as the cause of plant diseases are widely reported in almost all sugarcane growing countries [5]. Phytonematodes in sugarcane have been widely reported in several other countries, including China [6], South Africa [7], India [8], Nigeria [4], Japan [9], and Brazil [10]. In Indonesia, the initial study of phytonematodes in sugarcane was first reported in 1976-1978 in seven sugar mill areas in East Java [11].…”

Relationship between Nematodes and some Soil Properties in the Rhizosphere of Banana Plants

“…Furthermore, a positive correlation was found between temperature and electrical conductivity and nematode diversity. Finally, a negative correlation was found between soil moisture and pH and the proportion of nematodes, but no correlation was found between soil moisture content and nematode diversity (Gade and Hiware, 2017). In a study that investigated the infection of pineapple by Pratylenchus brachyurus, Sarah et al (1991) found a negative relationship between nematode population densities and soil pH.…”
