A sequential anode-cathode double-chamber microbial fuel cell (MFC) was constructed for the production of electricity using a novel microorganism, Clostridium sporogenes NCIM 5125 which is profoundly known to be a part of MFC studies. The growth of the microorganism was supported by energy derived from the electron transfer process itself and results in stable, long term power production. The electricity generation was optimized by analyzing the growth of the microbe at different parameters using mediated and non-mediated MFC. The results suggested that it is feasible to generate more electricity amounting to 5.6 mA at 160th h with the adopted C. sporogenes using mediated MFC.Keywords

Drought stress adversely affects the growth, development and ultimately yield of cotton. The growth and productivity of cotton plants depend largely on their vulnerability to environmental stress. Water stress is commonly attributed to situations where the water loss exceeds sufficient absorption intensity causing a decrease in plant water content, turgor reduction and, consequenctly, a decrease in cellular expansion and alterations of various essential physiological and biochemical processes that can affect growth or productivity. The experiment was conducted by adopting Factorial Randomized Block Design with three replications. The treatments comprised of water stress imposed at vegetative, squaring and boll development stages of crop growth.Withholding water at any growth stage significantly increased the leaf ABA content. Among the different treatments, stress at squaring had a major impact over the ABA quantity enhancement. Chlorophyll stability index is a measure of integrity of membrane or heat stability of the pigments under stress conditions. The genotype KC 2 X MCU 13 showed tolerance to water stress as it accumulated relatively higher ABA.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

Water stress adversely affects both yield and fibre quality of cotton (Gossypium spp L.). A study was conducted to determine the relative water content (RWC) and drought tolerant index (DTI) of cotton plants under water stress in cotton. The experiment was conducted by adopting Factorial Randomized Block Design with three replications. The treatments comprised of water stress imposed at vegetative, squaring and boll development stages of crop growth. In case of drought tolerant genotype, the leaves maintained higher RWC and photosynthetic activities under water stress than that of drought sensitive genotype. Prolonged water shortages virtually affect all the metabolic processes and often result in severe reductions in plant productivity.Keywords

A study was conducted in the Centre of Excellence in millets, Athiyandal, Tiruvannamalai district during Kharif’ (September, 2015-January, 2016). Scarcity of water is a severe environmental constraint to plant productivity. Millets are small-seeded grasses that are hardy and grow well in dry zones as rain-fed crops, under marginal conditions of soil fertility and moisture. This is important in heavily populated areas. The experiment was conducted by adopting Randomized Block Design with three replications. The morpho and physiological effects were positively correlated with yield components in varagu under rainfed condition. Growth regulator and nutrient spray on the crop growth period had significant influence on the plant height, relative water content, number leaves and yield component of the plant under rainfed condition.Keywords

The crop growth and development are constantly influenced by environmental conditions such as stresses which are the most important yield reducing factors in the world. Millets cultivation is the most important agricultural operation in the country, not only in terms of food security, but also in creating better livelihoods, opportunities for rural population. Water stress and other abiotic stresses can dramatically limit and reduce the plant growth and productivity. In the frame of physiological window, mild drought induces regulation of water loss and uptake in plants allowing maintenance of their leaf relative water content within the limits where the photosynthetic capacity shows no or little changes. But severe drought induces unfavourable changes in plants, leading to inhibition of photosynthesis and growth. The use of bioregulators is the quickest and surest way of boosting crop production under rainfed condition. Panchagavya is an organic product blended from five different cow products, commonly applied to crop plants in organic farming. It is used as foliar spray, soil application and seed treatment. It can act as growth promoter and immunity booster. The organic Panchagavya foliar spray significantly influenced various physiological and biochemical parameters. A field experiment was conducted at Centre of Excellence in Millets, Athiyandal, Tiruvannamalai, during Kharif, 2017 to study the effect of Panchagavya foliar spray for enhancing the productivity of tenai under rainfed situation. In a water shortage conditions, application of enriched FYM +Recommended dose of fertilizer + 3%Panchagavya foliar spray improves plant height, no. of tillers per plant, total dry matter partitioning, SPAD chlorophyll content and highest grain yield (1739.0 kg ha-1) of tenai under rainfed condition.Keywords
