Seven bacterial isolates (four of Psendomonas fluorescens and three of Bacillus subtilis) and seven isolates of fungal antagonists (six of Trichoderma spp, and one of Lentinns spp.) were tested for their ability to inhibit cowpea ischolar_main-rot pathogen, Macrophomina phaseolina under both in vitro and in vivo conditions. Among the bacterial antagonists, P. fluorescens charvae isolate recorded a maximum inhibition of mycelial growth of the pathogen followed by P. fluorescens isolate 2, whereas in fungal antagonists, T. koningii recorded a maximum inhibition followed by L. edodes and T. viride isolate 4. Pot-culture evaluation, under greenhouse conditions using P. fluorescens cliarvae, T. koningii and L. edodes revealed talc based powder formulation of P. fluorescens cliarvae and T. koningii was found to be the best in controlling ischolar_main-rot incidence of cowpea.Keywords

Continuous adaption of cereal-based cropping system has necessitated other alternatives such as pulses, which constitute a major part in agricultural economy of India. An experiment was conducted at Millet Breeding Station, TNAU, Coimbatore during Kharif (July, 2006 - October, 2006) in CO 6 green gram with nine different treatments. The yield and yield components were significantly increased by the application of chemicals and bioregulators. Various yield components such as days to 50 per cent flowering, days to maturity, number of clusters per plant, number of flowers per plant, number of pods per cluster, number of pods per plant, fertility co-efficient, number of seeds per pod, pod weight per plant, seed weight per plant, seed - pod ratio, pod length, hundred seed weight, grain yield per plot, grain yield per hectare and harvest index were favorably enhanced by the foliar spray of 0.1 per cent humic acid with 0.1 ppm brassinosteroid treatment.Keywords

Objectives: In the present study, economic analysis of with and without periphyton substrate (aquamat installation) as treatment and control, respectively, was evaluated with semi-intensive culture (stocking density 20 numbers m-2) of Penaeus vannamei. Total duration of the culture was 120 days.
Methods/Statistical analysis: Economic parameters of both ponds were estimated via fixed cost, variable cost and gross revenues, and performance indicators such as benefit cost-ratio (BCR), net profit, break-even price, rate of return on investment, rate of return on operating cost, production per man day and contribution margin were calculated based on the profitability and the capital investment. The primary data was used for the calculation and the experiment was carried out in duplicates.
Findings: The capital investment for periphyton (US$ 23192, INR 62.5= US$) was higher than the control pond (US$ 17544). Higher production in periphyton pond resulted in the increased net income generation by 35.4 % than the control. Periphyton improves the economic return (US$ 18021; BCR – 2.3) of the semi-intensive shrimp farming and reduced the breakeven point (496) and feed cost (US$ 7426) of the culture pond. This indicates that the aquamat installation in semi-intensive shrimp culture system is a profitable venture and paves the way to attain sustainable intensification in the shrimp farming sector. The study was conducted on the field; it depicts the exact scenario of the profitability of aquamat installation when compared to the laboratory trial.
Application/Improvements: This technology also reduces and recycles the wastes, so it can also be applied as economically viable effluent treatment system for shrimp farming.
