Keywords: Fly ash, Press mud, Exchangeable Calcium, Magnesium, Rice
Abstract: This investigation was carried out for the assessment of exchangeable nutrients availability in the soil due to the application of composted organic biosolids (fly ash & pressmud) and fertilizers as broadcast and deep placement under submerged and upland conditions. The two field experiments were conducted in sandy clay loam and sandy loam soils of Madukkur series (Typic Haplustalf) in Central farm, Agricultural College and Research Institute, Madurai during rabi (Nov 2006-Mar 2007) and kharif (July-Nov 2007) seasons, with ADT 39 rice as a test crop in split plot design. Exchangeable Ca and Mg were the highest with the application of fly ash and pressmud @ 6.25 t ha-1 each along with 75% NPK applied treatments. The availability of all these nutrients showed decreasing trend from active tillering stage to post harvest stage but the decrement observed in deep placement method is lower when compared to surface broadcasted one.

Keywords: Oryza sativa, Variability, Heritability, Genetic advance
Abstract: Genetic variability, heritability and genetic advance were estimated for various morphological and quality characters in 50 genotypes of rice [Oryza sativa]. The studies showed high range of phenotypic variation for grain yield per plant, days to 50 percent flowering, plant height, number of panicles per plant, panicle length, number of grains per panicle, 1000-seed weight and protein content. The coefficent of variation (PCV & GCV) was maximum for grain yield per plant (PCV = 28.4% & GCV = 25.8%) and minimum for days to 50 percent flowering (PCV = 9.6% & GCV =9.4%).The phenotypic coefficients of variations (PCV) were higher than those of genotypic coefficient of variation (GCV), which indicated greater influence of environment. High heritability along with high gentic gain was observed for number of grains per panicle (96.4 % & 51.3 %), number of panicles per plant (93.8% & 48.7%) and grain yield per plant (82.5% & 48.3%). High heritability with low genetic gain was observed for days to 50 percent flowering (96.7% & 19.1%). Considering the high estimates of genetic parameters like PCV, GCV, heritability and genetic advance together, it is evident that grain yield per plant, number of grains per panicle and number of panicles per plant are the most important characters.

Abstract: An attempt has been made to study the effects of body weight and sex on oxygen consumption in the air breathing murrel fish, Channa gachua. The oxygen consumption in C. gachua of different body weight in aquatic, aerial media and total oxygen uptake was noted as 68.3-37.2 ml/kg/h, 106.9-39.2 ml/kg/h and 175.23-76.32 ml/kg/h, respectively and was found inversely proportional to body weight. In male fish oxygen consumption in aquatic, aerial media and total was observed as 52.57, 65.14 and 117.71 ml/kg/h whereas in female fish recorded as 54.0, 56.97 and 110.97 ml/kg/h respectively. The result suggested the female fish consumed less oxygen but male fish took more oxygen due to their activities and life style.

Abstract: Histomorphological studies on the midgut of Orthaga exvinacea were carried out durign larval (on emergence & 48 h) and pre pupal (one day old pre pupa, 120 ha & three day old pre pupa, 168 h) development. The midgut is the largest portion of the alimentary canal during these stages. Histologically the wall of the midgut is composed of longitudinal and circular muscle layers, a thin basal membrane inner to the muscle layers and an epithelium in the basal membrane. The epithelium is composed of three types of cells, viz., columnar cells, goblet cells and regenerative cells. Below the epithelium is a thin peritrophic membrane. The larval epithelial layer is completely sloughed off from the basal membrane during three day old pre pupal stage. They were regenerated during pupal stage.
