The effect of bio-fertilizer was studied in banana accessions intensively collected from ICAR Research Complex for NEH Region, Mizoram Centre, Kolasib, Mizoram during 2009-2010. To assess the efficacy of different bio-fertilizer viz., Azospirillium, Azotobacter and phosphorus solubilizing bacteria (PSB) either alone or in combination was applied 20g per plant with recommended dose of FYM. The six treatments were arranged in a Randomized Block Design in three replications and spaced at 2.5 × 2.5 m in order to study its effect on growth, yield and quality attributing traits. All the characters were significantly increased except number of suckers and number of leaves due to application of each of the two-bio fertilizers either separately or in combination. Moreover in combination ofAzotobacter + PSB 20g per plant showed that more effective than either combination or in separately of another bio-fertilizers. This might be due to because biological nitrogen fixation depends appreciably on the available form of phosphorus. So the combined inoculation of nitrogen fixers and PSB may benefit the plant better (by providing both nitrogen as well as phosphorus) than either alone.Keywords

A clay bed is exposed near Garjia (Ramnagar) in the Nainital district of UP at the base of a gravel sequence akin to the Upper Siwalik Boulder Bed. Its principal clay constituent is represented by the smectite group of minerals of bentonitic composition derived from a volcanic source of silicic pyroclastic material. The clay shows similarity with the Toba ash.Full Text

Middle Jurassic rocks of the Habo Dome consist of well-preserved abundant trace fossil genera. These are described from the black limestone of Jhuno Formation and overlying thick classic sequence which is capped by thin bands of oolitic limestone of Jumara Formation. Total 30 ichnospecies of 23 ichnogenera are identified and their preservational aspects, ecological observations, producers and behavioural aspects are discussed. The trace fossils are found in subtidal sequences i.e. sandstone-siltstone-shale partings, thick, massive and cross-Bedded sandstones and in shelf sequences i.e. black limestone which consists of abundant Chondrites species with resting traces (Lockeia). The clastic sequence exhibits poorly sorted and intensely bioturbated cross-bedded sandstone, ripple-marked ferruginous sandstone and laminated shale-siltstone lithofacies which consist of three dimensional buiTow systems of Ophiomorpha, Thalassinoides and Spongeliomorpha, feeding burrows (Rhizocoralhum, Chondrites, Halymenidium, Gordia, Rutichnus, Planobtes) and crawling traces (Scolicia, Gyrochorte) Massive sandstone facies is moderately bioturbated while shale, conglomerate, shell bed and oolitic limestone lithofacies are poorly bioturbated (Thalassinoides). Wave and current energy, substrate consistency, food supply and bathymetry may have influenced the distribution of trace fossils m the shallow marine environments of the Middle Jurassic rocks of the Habo Dome.Keywords

Dhosa Oolite Member of the Jumara Formation comprises alternating bands of oolitic limestones and shales, exposed in Jhura dome of Mainland Kachchh, Western India. This sequence is highly bioturbated and exhibits a moderate diversity and behaviourally complex assemblage of ichnospecies. The rhythmically bedded sequence shows three different levels of preservation of traces. Epichnial tiering consists of moderately bioturbated oolitic limestone exhibiting horizontal or low-angle protrusive/retrusive biogenic laminae, commonly dominated by feeding structures like Rhizocorallium jenense, R. irregulare, Zoophycos brianteus and Zoophycos isp. The endichnial structures within the oolitic limestone can be separated into two different preservational trace fossil suites. The endichnial shallow suites consist chiefly of deposit feeders like Chondrites intricatus, C. targionii, Planolites beverleyensis, Taenidium cameronensis, Thalassinoides isp., Z. brianteus, Z. cf circinnatus and Zoophycos isp. and few suspension feeder forms like Palaeophycus tubularis; while endichnial deep suites consist of Chondrites intricatus, Skolithos linearis and Zoophycos isp. Hypichnial structures consists abundant, cylindrical, branched, horizontal, large-sized three dimensional feeding burrows of Thalassinoides isp. and somewhat irregular, obtuse angle ramification burrows of Phycodes isp., which are attached to the lower surface of the casting medium. The trace fossil association indicates Cruziana ichnofacies and abundance of Zoophycus species below the fair weather wave base level is largely a preservational artifact. The preservational processes of the trace fossils indicate soft substrate and diversity and their abundance reflects the other palaeoecological parameters of the open shallow marine environments.Keywords
