Interaction between wilt, root rot and root knot complex in lentil was evaluated and formulated its management strategies. Population of plant parasitic nematodes in rhizosphere was observed as pre - and post- sowing of of lentil and found that when variety K-75 was grown, the population of Meloidogyne sp. was increased to be 950, 1000, 1550, after 30, 60 and 90 days, respectively as compared to population 450, in case of essential population before growing of crop.

The purpose of this thesis was to exploit beneficial aspects of microbial rhizosphere communities, especially effective bacteria and fungi of turmeric plant C. longa. The results were expected to support fundamental documents for proposing a suitable integrated nutrient management for turmeric plant in Vietnam.

Conventional tillage practices may adversely affect long-term soil productivity due to erosion and loss of organic matter in soils. Sustainable soil management can be practiced through conservation tillage (including no-tillage), high crop residue return, and crop rotation.

The tomato crop attacked by early blight, late blight, leaf spots, anthracnose, Dampimg off, buckeye rot, wilts and root rots. Among these Damping off diseases in tomato caused by Rhizoctonia solani is very common to see in nurseries, an increased incidence of blight caused by Rhizoctonia solani was noticed in recent past in major tomato growing areas of Ranga Reddy district of Andhra Pradesh.

Conventional tillage practices may adversely affect long-term soil productivity due to erosion and loss of organic matter in soils. Sustainable soil management can be practiced through conservation tillage (including no-tillage), high crop residue return, and crop rotation. Microorganisms in the soil strongly influence soil processes fulfill key roles in the decomposition of organic matter...

Wilt caused by Fusarium oxysporium f. spciceris is a devastating disease of chickpea. It occurs in 2 stages; seedling stage (0-30%) and reproductive stage (0-57%). Annual chickpea yield loss due to Fusarium wilt was estimated to be 10% in India. So, our objective is to control chickpea wilt disease by using Trichoderma based biofilms as an alternative to chemical fungicides. Trichoderma viride is a potential antagonistic fungi which prevents diseases like wilt, brown rot, damping off, charcoal rot etc.

A field experiment was conducted at the Agronomy Research Farm of IGKV, Raipur, during the Rabi season of 2010-11 and 2011-12. Incorporation of tillage and weed management practices considerably improved the yield of chickpea interms of N-uptake, number of nodules per plant and microbial activities of rice rhizosphere.

A field experiment was conducted during kharif, 2017 at the Main Agricultural Research Station, agriculture college farm, Raichur to study the “Activity of soil enzyme and microorganisms in rhizosphere soil of maize (Zea mays L.) as influenced by different weed management practices”. The experiment was laid out in Randomized Complete Block Design with three replications and twelve treatments. It was evident that before sowing, the soil enzyme activity was on par in all the treatments.

Phosphorus is a major limiting factor for plant growth particularly in the tropics and subtropics areas. It play an important role in many biochemical process viz., energy storage and transfer, cell division, cell enlargement and several other processes in plants. The availability of P to plants is a problem owing to its slow diffusion and high fixation in soils. Due to low solubility and mobility in soil, phosphorus use efficiency is very low ranges from 10-20% in normal soil.

In the present study, all the three selected varieties of chilli viz. G-4, NP-46 and Faridabad were susceptible to dry root-rot caused by Rhizoctonia solani. The different modes of application of Trichoderma harzianum were found effective to manage the dry root rot but most effective was found with dry seed treatment.

Biological control is known to be effective eco-friendly method for the management of crop diseases (Cook and Baker, 1983). Rhizosphere antagonists were isolated from healthy rhizosphere soil samples of chilli collected from major chilli growing areas of Andhra Pradesh. A total of 20 rhizosphere microbes were isolated. Out of which (eight fungal antagonists, ten bacterial antagonists and two fluorescent Pseudomonads) were found to exhibit antagonism against chilli wilt pathogen. On further in vitro evaluation, nine isolates including four fungi, four bacteria and one pseudomonas sp.

In the field of plant pathology, exploitation of metal nanoparticles in bacterial disease management is a novel and needy approach. Green synthesis of nanoparticles is most prioritized because of their safe, eco-friendly nature and cost effectiveness. A total of 16 fluorescent pseudomonad isolates were obtained from different crop rhizosphere in various locations.

Management of crop diseases by biological control is an alternative and effective approach with minimum deleterious effect on environment and human health for ecosystem stability leading to improvement in crop yields. The present study was undertaken to characterize antagonistic rhizosphere bacteria against phytopathogenic fungi i.e., Neovossia indica and Rhizoctonia solani, which cause Karnal bunt and root rot disease, respectively. Twenty two rhizobacterial isolates out of total 88 isolates obtained from wheat rhizosphere, 25% isolates inhibited the growth of both R. solani and N.

The activity of dehydrogenase (µg TPF produced g-1 day-1 ) followed decreasing trend from before treatment imposition to 3 days after treatment imposition thereafter it showed increasing trend. Sulfonyl urea herbicides had the lower dehydrogenase activity immediately after herbicide application as compared to the other herbicide group’s viz., chloroacetamide, triazolepyramidine, pyramidinethiobenzole and aryloxyphenoxy propionate. Urease activity (g of NH4 + released g-1 soil 2 hr-1 ), increased from 0 DAT up to 45 DAT and thereafter it decreased.

In modern agriculture there is a pivotal role of pesticides in pest management though, the side effect pesticides on soil biological system is non avoidable. Experimental result shows that imidacloprid recorded 21.42% increased azotobacter population while chlorpyrifos recorded 31.04% less azotobacter in comparison with untreated check. All the treatments showed negative impact on the rhizobium population and rate of growth inhibition was 30.81% to 55.18%; whereas the inhibition rate was ranged 22.08% to 54.37% in case of total bacteria population.

Plant growth promoting rhizobacteria (PGPR) were isolated from rhizospheres of coleus (Coleus forskohlii) and ashwagandha (Withania somnifera) from different parts of Karnataka. Isolated PGPR strains were screened for their efficacy against three soil-borne pathogens like Fusarium, Ralstonia and Meloidogyne in coleus and ashwagandha. Meloidogyne incognita causes root-knot disease complex and in conjunction with other two pathogens.

Eight native strains of Pseudomonas spp. were isolated from rhizosphere of various sugarcane clones on Pseudomonas agar using standard protocols. These strains were characterized for antagonistic traits on red rot pathogen in vitro and Plant growthpromoting (PGP) activities in greenhouse up to 30 days from single node setts in portrays as sett treatment (@109 CFU ml-1 ). The promising isolate was characterized up to species level by PCR amplification of 16S rDNA region using Pseudomonas specific primers. Elite strain was identified as P. putida strain AKP-1.
