STUDIES ON CERTAIN ECOLOGICAL ASPECTS OF SOIL FUNGI. VII

Mycoflora of soils, separately amended with urea, ammonium sulphate, superphosphate, organic manure and fresh leaves/twigs of Ipomoea fistulosa and regularly irrigated, has been investigated. Each amendments was applied at 60 kg/acre. 52 fungal species, comprising 7 spp. of Phycomycetes, 1 Ascomycetes, 38 spp. of Deuteromycetes and 7 sterile colonies, were isolated from the amended and control plots. Fungal population was higher in the amended soils as compared to control. Organic manure and irrigated plots, however, possessed more fungal populations. Among the fertilized plots, the ones amended by urea gave the highest yield, followed by those amended by superphosphate and ammonium sulphate in the decreasing order. During early stages, the plots supplemented with I. fistulosa gave considerably low fungi, with the population, however, increasing at the later stages. The increased nutrition status by various amendments has been emphasized for the increased mycoflora in the amended plots. (Full paper at Slideshare.net)

STUDIES ON CERTAIN ECOLOGICAL ASPECTS OF SOIL FUNGI. VI

Ten soil samples belonging to 7 soil type (up-lying cultivated field, low-lying cultivated field, garden, waterlogged area, usar, barren land and old mound) were collected from three districts, viz., Hardoi, Lucknow and Unnao of Uttar Pradesh (India). These have been assayed for their mycoflora. A total of 65 fungal species, comprising 10 Phycomycetes, 6 Ascomycetes, 43 Deuteromycetes and 6 mycelia sterilia were isolated. In most of the soil samples, Deuteromycetes were maximum in number followed by Phycomycetes, Ascomycetes and mycelia sterilia. Trichoderma viride and Aspergillus flavus were present in all the soil types. The garden locality displayed the highest fungal population. Cultivated localities also exhibits good fungal population which appreciably lowered in submerged, usar and barren soil. However, the lowest population was recorded in old mound. A correlation between habitat, cover vegetation and physico-chemical characters has been established. (Full paper at Slideshare.net)

STUDIES ON CERTAIN ECOLOGICAL ASPECTS OF SOIL FUNGI. III

Certain ecological aspects of soil fungi from three different localities. viz., forest, cultivated field and grassland, quite near to each other, have been studied. The forest was chiefly dominated by Sal (Shorea robusta). Triticum vulgare, Pisum sativum and Brassica campestris (in winter), Pennisetum typhoides, Sorghum vulgare, Zea mays and different Phaseolus spp. (in rainy season) were grown in cultivated field whereas in grassland Cynodon dactylon was the dominated species. sample were collected from 8 different depths, viz., 0-2, 2-7, 7-12, 12-17, 17-25, 25-35, 35-45 and 45-60 cms separately in sterilized soil containers. The sampling of soil was continued for a year in 3 different seasons i.e. summer, rainy and winter of the year 1970. The fungal population was generally found to be highest in upper layer and with an increase in depth the fungi per gm dry soil decreased gradually. Amongst 3 localities, fungal population was highest in forest sample and lowest in the grassland in all the corresponding depths. The maximum population in forest and cultivated localities was recorded during rainy season whereas in grassland it was in winter. The lowest population was always in the summer season. Organic matter content, moisture content, pH, depth of the sampling spot, locality and seasonal variation seem to play important role in distribution of mycoflora. Aspergilli were in majority through the investigation. (Full paper at Slideshare.net)

STUDIES ON CERTAIN ECOLOGICAL ASPECTS OF SOIL FUNGI - II

The mycoflora of twenty-one soil samples, collected from eight districts, viz., Aligarh, Nainital, Hardoi, Unnao, Lucknow, Gorakhpur, Deoria and Jaunpaur has been described. Apparently similar localities situated widely apart and closely situated localities with diverse characteristics have been surveyed. The fungal population was generally higher in cultivated fields. The different cultivated fields, however, exhibited remarkable variation in their fungal population. Higher population was obtained in three low lying cultivated fields which were under crop cover for short duration in the year. Nature and duration of cropping affected the population. Longer the period the field was under crop coverage higher the fungal population. Uncultivated barren localities like usar land and hillock top possessed lower fungal flora. The type of fungal species associated with different samples differed to some extent. The maximum number of fungal species i.e. 28, was obtained from cultivated field and the minimum i.e. 05 from bare mound. The members of Deuteromycetes outnumbered others followed by the members of Phycomycetes, Ascomycetes and Basidiomycetes. The Actinomycetes and mycelia sterilia were also infrequently isolated from certain localities. Physico-chemical charactes of the soil, i.e. moisture content, organic matter content and pH also affected the soil fungal flora. (Full paper at Slideshare.net)

Studies on certain ecological aspects of soil fungi

Eight localities of village Bhatauli of Unnao district, Uttar Pradesh (India) have been analysed for their soil mycoflora. 52 fungal forms belonging to 29 genera with two members of mycelia sterilia were isolated. Eight species (confined to 7 genera)of Phycomycetes, 3 spp. (2 genera including one Ascogenous species of Aspergillus) from Ascomycetes, 39 spp. belonging to 20 genera of Deuteromycetes and two mycelia sterilia (white and black one each)comprise the total population. Genus Aspergillus alone represents 13 species, viz., A. nidulans, A. fumigatus, A. sydowi, A. flavus, A. terreus, A. terreus var. Africanus, A. flavipes, A. niger, A. aculeatus, A. ochraceus, A. tamarii, A. carncus and A. gorakhpurensis and shows wide distribution in all the localities. On the other hand, few species like Botryodiplodia sp., Fusidium viride, Helicostylum piriforme, Humicola fuscoatra, Penicillium expansum, Pythiopsis sp., Stachybotrys atra, Scopulariopsis sp., Stysanus stemonites and white sterile form were confined to only limited localities. Relationship of various other factors viz., organic matter, moisture content and pH of the soil with fungal population has also been studied. (Full paper at Slideshare.net))

Mushroom Awareness Program at Ayodhya, 2016 (Part-1)

Urbanization has not left enough land for farmers to cultivate different crops. Due to this reason food crisis and malnutrition especially in terms of protein and micro nutrients has developed both in rural and urban areas which is resulting higher incidence of disease like diarrhoea,malaria, measles and acute respiratory infections among malnourished children. In addition to infectious disease, malnutrition is associated with delayed mental development and even growth retardation. In such circumstances, efforts in search of alternative resources of food may be of greater importance. Infact, it is the availability of food sources like meat, mollusks, insects, algae, yeast etc. which can meet up the shortage of food stuff to a considerable extent but unfortunately it may not be adopted by Indian market due to food taboos which prevent people from consuming nutritious food even when these are easily available. Several superstitions, belief and some time religion also have a powerful influence on the food habit of the people. Mushroom may have been considered suitable in this respect which provide a rich addition to the diet in terms of protein, vitamins, minerals and carbohydrates. Keeping this in mind, a mushroom awareness program has been conducted under the banner of Sri Laxman Prasad Pyare Lal Agro Products, Ayodhya during the month of January, 2016. This program was conducted under my supervision. The students of different institutions viz., K.S.S. P.G. College, Sri Paramhans Girls Degree College, Sri Paramhans Agriculture College, Raj Bali Smarak Public Inter Collage, S.R.K.M.K. Higher Secondary School and Modern Study Center took parts on different dates.

A press conference was also arranged at this center on January 22, 2016. In which, journalist from the different leading news papers i.e. Dainik Jagran, Amar Ujala, Hindustan, Janmorcha and Awadh Comment Week took part and covered the work which is being done at this center for the awareness of mushroom production and their consumption in related to protein deficiency problems. This conference was convened by Dr. R.S. Kanaujia and Dr. C.S. Singh Ex. Associate Professor of Botany department, K.S.S. P.G. College, Ayodhya, who are credited for the awareness of mushroom in this area by their untiring efforts through their continuous research program pertaining to mushroom science in last two decades. They revealed the need of mushroom cultivation along with their cultivation technology and health benefits in the press conference. They also narrated the future activities of the firm.
