<p>The fruits and vegetables lost due to spoilage in the market can be converted to nutrient rich organic biofertilizer, vermicompost and worm tea. In this study, non-edible vegetables from market [French beans (S1), Lady’s fingers (S2) and Brinjal (S3)] were used for production of vermicompost and worm tea using <em>Eisenia fetida</em> for environmental friendly management and recycling, as value added product for crop production. Vermicomposting was carried out in four bins. Three bins (S1, S2 &amp; S3) consisted of individual pre-digested vegetables and the fourth bin (S4) was set up with a mixture of all three pre-digested vegetables in equal proportions. Physico-chemical properties and essential nutrients like pH, temperature, moisture content, total organic carbon (C), total nitrogen (N), available phosphorus (P) and exchangeable potassium (K) of the pre-digested vegetables and/or compost were analysed at regular time intervals. There was around 6-10 fold increase in earthworm count at the end of vermicomposting. During vermicomposting, the N and P content of the compost showed 2 to 4 fold increase whereas 10 to 15 fold increase in K content was noticed. Low C:N ratio (4 to 9) was obtained for vermicompost VS4. The worm tea (vermi wash) and vermicompost collected were used for plant growth studies on <em>Vigna radiata</em> (Green gram). Growth parameters like germination percentage, vigour index, germination index (GI), shoot length (cm), root length (cm) and leaf length (cm) were studied. There was noticeable improvement in germination % (1.7 fold), vigour index (2.7 fold) and germination index. A 20 fold increase in shoot length was also seen in test plants when compared to control (2 fold). Statistical analysis of various growth parameters like root length and plant height indicated that vermicompost made with waste brinjal has a significant response with p ≤ 0.05. Based on the results obtained, waste brinjal, which is abundantly available locally can be economically converted to organic biofertilizers and used for soil and crop improvement. Through this study, a cost effective and environment friendly method for efficient utilization of market waste vegetables has been proposed for promoting plant growth and development.</p>

Plant growth and the expression of two transporter genes; PoHKT1 and PoVHA transcripts in root and shoot tissues were studied under salt stress of three Portulaca oleracea s.l. taxa. The study showed no significant differences in ratios between root lengths in saline and non-saline treatments of the three taxa, which was correlated with a clear down-regulation of the PoHKT1 transcripts in the root after 150mM NaCl. All measured growth parameters except root length increased in P. oleraceae, decreased in P. granulatostellulata and remain unchanged after 100mM NaCl in P. nitida compared to control under saline conditions. The result was consistent with the type of taxon which had significant effect on the shoot length, number of leaves and dry weight (P< 0.05). All measured growth parameters except root length showed a significant negative correlation with the shoot fold change of PoHKT1 transcripts (r = -0.607, -0.693 and -0.657 respectively). The regulation of PoVHA in root and shoot tissues in the three taxa are significantly different. Under salt stress, both decreased uptake of Na+ into the cytosol by decreasing the expression of PoHKT1 and increased vascular compartmentalization ability of Na+ by inducing the expression of PoVHA seem to work more efficiently in P. oleraceae and P. nitida than in P. granulato-stellulata.

The study was carried out as a pot experiment in controlled conditions in order to reveal the effect of endophyte bacteria (EB) applications on the development of pepper seedlings grown under different drought stress. Mostar F1 was used as pepper variety. Applied endophyte bacterial isolates were Ochrobactrum sp. (CB36/1) and Bacillus sp. (CA41/1). The EB application was applied twice (first application 10 ml- second application 15 ml) at a density of 109 cfu/ml. All pots were irrigated regularly for 52 days after seed sowing. While irrigation was continued at 2-day intervals in control (B0) applications, four and eight days drougth stresses were applied in the second (B1) and last (B2) application. As plant growth parameters, stem diameter, shoot length and root length, shoot fresh and dry weights, leaf number, root fresh and root dry weight were examined. It has been determined that the effects of B1 and B2 stress applications on plant growth were generally negative. It has been determined that endophyte bacteria applications have relatively positive effects against the negativity caused by different drought stresses.

In the present rapid growing world, need for a sustainable agricultural practice which helps in meeting the adequate food demand is much needed. In this context, plant growth promoting bacteria were brought into the spot light by the researchers. Though the plant growth promoting bacteria have several beneficial applications, due to some of the disadvantages in the field conditions, they lagged behind. In the current research work, native PGPR were isolated from the rhizosphere soil samples of maize with an aim to isolate the nitrogen fixing, phosphate solubilising and potash solubilising bacteria. Out of the several isolates, potent PGPR isolates viz., Paenibacillus durus PCPB067, Bacillus megaterium PCBMG041 and Paenibacillus glucanolyticus PCPG051 were isolated and identified by using the 16 S rRNA gene sequencing studies. Genomic DNA sequences obtained were deposited in the NCBI Genbank and accession numbers were assigned as MW793452, MW793456 and MW843633. In order to check the efficacy of the PGPR isolates, pot trials were conducted by taking maize as the host plant. Several parameters viz. shoot length, shoot weight, root length, root weight and weight of the seeds were tested in which PGP treatment showed good results (shoot length - 187±3.5 cm, shoot weight - 31±4 g, root length - 32±3.6 cm, root weight - 17±2 g, yield- 103.3±6.1 g) when compared to the chemical fertilizer treatment (shoot length - 177±3.5 cm, shoot weight - 25±3.6 g, root length - 24±3.5 cm, root weight - 14.6±1.52 g, yield- 85.6±7.6 g). Based on the results, it can be stated that these native PGPR isolates can be effectively used in the plant growth promotion of maize.

The continuous rise in global population demands more food production under limited land resources accompanied by climate change. More oversupply of quality seeds to meet ever-growing food demand is a highly challenging task. Seeds with low vigour level limit the growth and yield of crops at varied field conditions. Hence, an experiment was conducted to develop a technique for the fast and homogeneous growth of kabuli chickpea seeds. The priming treatments evaluated in the present study enhanced the various seed quality parameters of kabuli chickpea significantly when compared to control. Hydro-priming for 4 hours (at 20°C) and air drying for 72 hours showed better results compared to rest of the treatments both in fresh seeds which recorded higher first count (66.38%), germination (92.50%) root length (11.85 cm), shoot length (6.16), mean seedling length (18.01), dry seedling weight (747 mg), seedling vigour index-I (1665), higher speed of emergence (0.3992) and old seeds with higher first count (61.88%), germination (74.13%) root length (8.15 cm), shoot length (5.85 cm), mean seedling length (14.00 cm), seedling dry weight (611 mg), seedling vigour index-I (1056), higher speed of emergence (0.3814). The aged seeds have recorded 29 % increase in germination percentage in contrast to 8 percent increases in fresh seeds. Kabuli chickpea seeds could be subjected to hydropriming, an affordable, alternative, and eco-friendly technique for improving seed and seedling vigour of kabuli chickpea.

This study was carried out to explore herbicidal potential of an asteraceous weed Ageratum conyzoides against an exotic noxious weed parthenium (Parthenium hysterophorus L.). Different concentrations (0, 2, 4, 6, 8 and 10%) of aqueous extracts of various parts of the tested weed were used in laboratory bioassays. ANOVA revealed the significant effect of plant part bioassay and extract concentration on germination as well as various root and shoot growth parameters. Leaf extract was found the most herbicidal where a 10% extract completely inhibited the germination and growth of parthenium. Root and inflorescence extracts were also highly inhibitory in suppressing the germination up to 89% and 95%, shoot length up to 80% and 89%, root length up to 86% and 91%, and plant biomass up to 89% and 98%, respectively. Stem extract showed the least herbicidal activity causing up to 46%, 59%, 73% and 37% reduction in germination, shoot length, root length and plant biomass, respectively. This study concludes that leaf, root and inflorescence extracts of A. conyzoides possess strong herbicidal potential against germination and growth of parthenium.

Arsenic (As) is a well-known toxic metalloid found naturally and released by different industries, especially in developing countries. Purple nonsulfur bacteria (PNSB) are known for wastewater treatment and plant growth promoting abilities. As-resistant PNSB were isolated from a fish pond. Based on As-resistance and plant growth promoting attributes, 2 isolates CS2 and SS5 were selected and identified as Rhodopseudomonas palustris and Rhodopseudomonas faecalis, respectively, through 16S rRNA gene sequencing. Maximum As(V) resistance shown by R. faecalis SS5 and R. palustris CS2 was up to 150 and 100 mM, respectively. R. palustris CS2 showed highest As(V) reduction up to 62.9% (6.29±0.24 mM), while R. faecalis SS5 showed maximum As(III) oxidation up to 96% (4.8±0.32 mM), respectively. Highest auxin production was observed by R. palustris CS2 and R. faecalis SS, up to 77.18±3.7 and 76.67±2.8 μg mL−1, respectively. Effects of these PNSB were tested on the growth of Vigna mungo plants. A statistically significant increase in growth was observed in plants inoculated with isolates compared to uninoculated plants, both in presence and in absence of As. R. palustris CS2 treated plants showed 17% (28.1±0.87 cm) increase in shoot length and 21.7% (7.07±0.42 cm) increase in root length, whereas R. faecalis SS5 treated plants showed 12.8% (27.09±0.81 cm) increase in shoot length and 18.8% (6.9±0.34 cm) increase in root length as compared to the control plants. In presence of As, R. palustris CS2 increased shoot length up to 26.3% (21.0±1.1 cm), while root length increased up to 31.3% (5.3±0.4 cm), whereas R. faecalis SS5 inoculated plants showed 25% (20.7 ± 1.4 cm) increase in shoot length and 33.3% (5.4 ± 0.65 cm) increase in root length as compared to the control plants. Bacteria with such diverse abilities could be ideal for plant growth promotion in As-contaminated sites.

An experiment on seed quality enhancement of common bean (Phaseolus vulgaris L.) var. S 9 (local) was conducted at the department of seed science and technology, OUAT, Bhubaneswar during 2013-14 by use of three biocontrol agents viz. Trichoderma viride, Trichoderma harzianum, Pseudomonas fluorescence. Seeds were bi-oprimed with the biocontrol agents at 40, 50 and 60 % concentration for 4,8,12 and 16 hours of soaking. Seeds were also hydro primed for 4,8,12 and 16 hours. Unprimed dry seed resulted in germination (69 %), shoot length (27.5 cm), root length (14 cm), seedling dry weight (1.71g), SVI-I (2859.2), SVI-II (118.0) and speed of germination (5.8) while hydro primed seeds resulted in germination (72%), shoot length (31.9 cm), root length (15 cm), seedling dry weight (1.80 g), SVI-1 (3375.9) SVI-II (129.8) and speed of germination (6.7). Trichoderma harzianum at 40% con-centration and for 4 hours of soaking resulted enhancement of above quality parameter like 13.0 % in germination, 21.1 % in shoot length, 20.7 % in root length, 31.6 % in seedling dry weight, 36 % in seedling vigour index-I, 48.1 % in seedling vigour index-II and 58.6 % in speed of germination over unprimed seeds. Bio priming with P. fluorescence ( at 40% concentration and for 4 hour) closely followed and at par with best treatment with 11.6 %, 18.2 %, 16.4 %, 30.4 %, 30.7 % and 56.9 % enhancement of above mentioned quality parameters, respectively.
