Two hundred and twenty two water samples were collected from August 2008 to April 2009, which including 49 samples from 13 water purification plants in Basrah governorate (13 samples prior entering to the plants, 13 from precipitation, 10 from filtration tanks and 13 samples from the water coming out of these plants). Furthermore 127 samples of tap water were collected from 18 districts around Basrah governorate. Also 46 samples were collected from tankers which supplying Reverse Osmosis (RO) in 19 different places and from five RO water supplying plants in the governorate.

In the present study aimed to evaluate the growth inhibitory effect of Hibiscus rosasinensis, Azadirachta indica, Ficus religiosa and Ocimum sanctum leaves extracts on Esherichia coli, Salmonella typhii, Staphylococcus aureus and Enterobacter aerogen. Aquous plant extracts were tested against 4 bacteria. Gel diffusion method, were used in this investigation. The antibacterial activity of Azadirachta indica plant extract was exhibited maximum zone of inhibition against Esherichia coli 14 mm (Mean value in Dia.), when compared with other medicinal plant extracts.

Field experiment was undertaken to find out the influence of different orgaftfc inputs and growth regulators on growth, yield and quality of French marigold (Tagetes patula L.) cv. Sindhamani, in a farmer’s field at Sivapuri near Annamalainagar, Tamil Nadu. The experiment was laid out in randomized block design with three replications. Various organic inputs and growth regulators including panchagavya 3%, vermiwash 1:5 dilution, humic acid 0.02%, gibberellic acid 300ppm, triacontanol at 250 ppm were applied.

The study was designed to evaluate the impact of different fertilizer on the growth and yield of soybean varieties at Babcock university farm, Ilishan-Remo in 2009 and 2010. The experimental design was a randomized complete block (RCBD) using three replications. The treatments are three varieties of soybean: (TGx 1740-2F), (TGx 1842 - IE) and (TGx 1448 -2E) and four different fertilizers application: 4ton/ha compost; 30kgN/ha, urea, combination of 2ton/ha compost and 30kgN/ha urea, and (a control).

A total of 60 suspected cutaneous leishmaniasis (CL) cases were diagnosed during the period from December, 2013 to February, 2014 with females representing 67% of the cases. The incidence rate with CL was 88.3% by using Real-Time PCR. Fourty -two (70%) of isolates from different patients were typed as L. major and 11 (18.3%) of isolates were typed as L.tropica while 7 (11.7%) of cases were gave negative results. The present investigation revealed that the highest number of patients 24 (40%) was in age group (10 and less) year.

In the present study, breeding information spread over a period of 14 years from 1995 to 2008, was collected from the history-cum-pedigree sheets and milk yield registers of Murrah buffaloes maintained at four centres of Network Project on Murrah Buffalo Improvement (National Dairy Research Institute, Karnal; Central Institute for Research on Buffalo, Hisar and Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana and Choudhary Charan Singh Haryana Agricultural University, Hisar). Data on first lactation traits of 832 Murrah buffaloes sired by 95 bulls were used for the study.

Tukra is one of the major problem in mulberry growing areas and it is caused by pink mealy bug Maconellicoccus hirsutus which affect both the quality and yield of mulberry leaf. A preliminary attempt has been made to control tukra in mulberry using plant extracts of natural pesticide origin. The seed kernel and leaf extracts of Azadirachta indica, Pongamia pinnata, Madhuca longifolia and only leaf extracts of Lantana camara, Adathoda vasica were directly used as a foliar spray in the control of tukra in M-5 mulberry variety. Total of four sprays were given with an interval of 7 days.

Rapid urbanization in the world is quite alarming, especially in developing countries such as India. In the present study historical change in urban area was analyzed using multi-temporal satellite images of 1980, 2000, 2010 and 2013 respectively to identify the areas where the increase or decrease has taken place over the period of last 33 years. High resolution satellite data of CARTOSAT 1 and 2 was used for base map and Digital Elevation Model generation.

Mulberry, Morus alba L., the only host plant of silkworm (Bombyx mori L.,) is attacked by about 300 species of insect pests. Among them, pink mealy bug, Maconellicoccus hirsutus Green is the most serious causing more than 35 per cent yield loss besides impairing nutritional quality of mulberry leaves. The management of pink mealy bug by using plant products is gaining attention due to proven specificity, biodegradability, low toxicity to non target organisms and low residual toxicity in the mulberry ecosystem.

A newly isolated Pseudomonas aeruginosa MTCC 4996 capable of degrading phenol Pseudomonas aeruginosa MTCC 4996 cells were immobilized with six different matrices. All the immobilized matrices showed faster degradation than free cells. Among the matrices, PUF immobilized cells showed maximum degradation followed by alginate and k-carrageenan, agarose, polyacrylamide and hen egg white. P. aeuriginosa MTCC 4996 cells immobilized with PUF were showed 100% degradation up to 1400 mg/l within 750 min.
