The growth of Actinobacteria was evaluated in a new modified nutrient agar media (MNA) supplemented with 1% sodium chloride (NaCl) and compared with the universally accepted media which are under regular use. Thirteen different Actinobacterial isolates were evaluated for their growth in both solid and liquid media in MNA along with four regularly used media ISP-2, kenknight, starch casein and nutrient media. Results indicated that eight isolates (Streptomyces bulli, Streptomyces griseorubens, Streptomyces viridobrunneus, Streptomyces A3, Streptomyces A7, Streptomyces A11, Streptomyces A12 and Streptomyces A13), out of thirteen isolates could grow significantly faster on MNA compared with other solid agar media. Similarly, growth in liquid media recorded by optical density (OD) indicated that three isolates (S. griseorubens, S. viridobrunneus and A7) showed significantly higher OD followed by ISP-2, nutrient, starch casein and kenknight broth after seven days of incubation. All the isolates except S. viridobrunneus and Streptomyces A12 could tolerate NaCl concentration upto 6% in liquid modified nutrient broth. The present study showed that Actinobacteria can be successfully grown faster with full pigmentation at 1% NaCl concentration and they can tolerate up to 5% NaCl concentration, in the new proposed MNA media.Keywords

Maize has the highest potential yield and responds greatly to applied fertilizers especially in the irrigated conditions in Tamil Nadu. Phosphorus and sulphur are the major yield limiting factor after nitrogen in the study area- Sivagangai district of Tamil Nadu. Therefore, this study was initiated with the aim of increasing the yield of hybrid maize by optimizing the phosphorus and sulphur fertilizers in the farmer's field. The experiment was laid out in a Factorial Randomized Block Design replicated thrice with five levels of phosphorus viz., 0, 50, 75, 100, 125 kg P2O5 per ha and five levels of sulphur viz., 0, 20, 40, 60, 80 kg S per ha. The results revealed that plant height, dry matter production, cob length, cob girth, the number of grains per cob and hundred grain weight were significantly increased with increased dose of P and S, and significantly higher at 125 kg P2O5 per ha and 80 kg S per ha. Similarly, the maize grain yield was higher at 125 kg P2O5 per ha (5964 kg per ha) and 80 kg S per ha (5035 kg per ha). Interaction of phosphorus and sulphur was additive with respect to growth and yield of maize.Keywords

A field experiment was conducted on vertisolsat Natural Resources Protection and Development Society Research Station, Namakkal during Rabi season of 2012-13 and 2013-14 to study the effect of organic manure sand rock phosphate on growth and yield of Bengal gram (Cicer arietinum L.) in vertisols of Tamil Nadu. Significantly higher grain yield was recorded with rock phosphate application @ 200 kg/ha (2140 kg/ha) over 50 kg and 100 kg of rock phosphate per hectare except rock phosphate @ 150 kg/ha (2069 kg/ha). Interaction effect of compost 5 t along with rock phosphate 200 kg/ha recorded significantly higher grain yield 2130 kg/ha) and haulm yield (3300 kg/ha) over other treatment combinations except either for organic manures FYM 5 to rcompost 5 t along with 150 to 200 kg rock phosphate per ha. Significantly higher B:C ratio (3.32)was recorded with rock phosphate @ 200 kg/ha over other lower levels. Similarly, combination of compost @ 5 t/ha with 150 kg rock phosphate resulted in higher B:C ratio (3.37).Keywords

Diabetes mellitus (DM) is a global health problem and the incidence of DM is increasing at alarming rate all over the world. Many Indian medicinal plants have been reported to possess potential anti diabetic activity and could play important role in the management diabetes. The present study aimed to evaluate anti diabetic activities of ethylacetate extract of Azima tetracantha Lam leaf in streptozotocin-induced diabetic rats. Diabetes was induced in male wistar rats by single intraperitoneal injection of streptozotocin (50 mg/kg b.wt.). The diabetic rats were administered orally with Azima tetracantha Lam leaf ethyl acetate extract at two different doses (150 and 250 mg/kg b.wt./day) for 18 days. At dose levels of 150 and 250 mg/kg, glucose levels were decreased by 24.8% and 29.9% at the 6th hour, respectively. Anti diabetic effect of the extract was slightly decreased at the 8th hour, but remained statistically significant. An overall reduction of 26% was observed on the 18th day by 50mg/kg administration (p<0.01). 52.5% reduction of glucose level in the serum absorbed at 18th day administration at dose level of 150 mg/kg (p<0.0001). 250mg / kg extract administration is more effective from 6th day onwards with a reduction rate of 18.9% (p<0.01) and maximum reduction of serum glucose level by 61.9% on the 18th day. Rats treated with higher doses of the extract (150 and 250 mg/kg) showed significant improvements in hepatic and renal function. Additionally, these two dose levels recovered the weight loss and low white blood cell count observed in Streptozotocin-diabetic rats while decreasing liver glycogen. Azima tetracantha Lam leaf ethyl acetate extract (150 and 250 mg/kg) also showed a protective effect on liver oxidative status. The results of present study showed that Azima tetracantha Lam leaf ethyl acetate extract possess significant antihyperglycemic activity and supports the traditional use of Azima tetracantha Lam leaf for the treatment of diabetes mellitus.Keywords

Brown planthopper, Nilaparvata lugens, is the major pest of rice in India and causes significant yield loss. It causes damage by sucking the plant sap leading to a characteristic symptom called ‘hopper burn’. The present study was undertaken to assess the genetic variability of N. lugens populations from different rice ecologies in India, to comprehend and assist in planning proper management strategies. We evaluated the molecular diversity in 17 N. lugens populations based on internal transcribed spacer 1 (ITSI) gene sequences. In all, 53 unique haplotypes were identified and their numbers varied from 1 to 10 in the sampled populations. Genetic diversity indices like nucleotide diversity, haplotype number, haplotype diversity and average number of nucleotide differences revealed low to high levels of genetic diversity among the populations. A highly significant negative relation of Fu’s F and Tajima’s D tests with insignificant sum of square deviation (SSD) values indicated possible recent expansion of N. lugens in different Indian regions with a population expansion time of 3.9 million years. A non-significant correlation in isolation pattern by distance indicated that geographic barriers present in India are inadequate to bring genetic differentiation among N. lugens from different migratory populations. In the present study, the ITSI gene sequence was used to analyse genetic structure among N. lugens in India.Keywords
