The Impact

A field experiment was conducted during rabi season of 2015-2016 at Navsari Agricultural University, Navsari to study the impact of cobalt application methods on chickpea yield, nutrient content and soil status. Four cobalt application methods with three levels of each were evaluated with one absolute control and one with seed priming of water were evaluated with randomized block design with three replications. Least level of seed treatment, soil application and foliar application of cobalt gave highest chickpea seed yield and decreased there after. As cobalt levels increased, NPK content and uptake are decreased linearly in all the methods except seed priming method, however cobalt content and uptake increased linearly by seed treatment and foliar application, on the contrary it decreased linearly by seed priming and soil application of cobalt. Soil application of cobalt at 50 g ha-1 recorded highest chickpea seed yield, residual NPK and Co and which can be useful for succeeding crop and this can be recommended from the cobalt nutrition point of view in plants and animals followed by seed priming at 1 ppm.

Azospirillum bioinoculant is well known for its high nitrogen-fixing and plant growth-promoting characters. Carrier-based bioinoculants generally suffer from shorter shelf-life, poor quality, high contamination and low field performance. As an alternative, the liquid and cyst formulations of Azospirillum inoculants can play a significant role. Liquid and cyst formulations of Azospirillum were developed by adding amendments to the NFb broth and to MSM medium, respectively, which have longer shelf-life and tolerance to adverse conditions such as temperature and desiccation. The dosage of liquid and cyst-based formulations of Azospirillum for various inoculation methods such as seed treatment, seedling root dipping and soil application was standardized and their survival was studied. Inoculum levels of 10 ml/kg seeds, 150 ml/quantity of seedlings required for 1 ha and 300 ml/ha were found to be the optimum doses for seed treatment, seedling root dipping and soil application methods, respectively. The liquid and cyst formulations of Azospirillum have exhibited better adherence and survival on seeds, seedling roots and in the rhizosphere than the carrier-based form. These results indicated that there is substantial room to improve the liquid and cyst formulations of Azospirillum inoculant to obtain the desired benefits.

BurkholderiaSP. Strain TNAU-1 for Biological Control of Root Rot in Mung Bean (Vigna RadiataL.) Caused byMacrophomina PhaseolinaThe potential ofBurkholderiasp. strain TNAU-1 for the management of mung bean (Vigna radiataL.) root rot caused byMacrophomina phaseolinawas evaluated under greenhouse conditions.Burkholderiasp. strain TNAU-1 inhibited the mycelial growth ofM. phaseolina in vitroand produced an inhibition zone of 18.8 mm. Mung bean seeds when treated with the bacterial suspension, showed significant increase in root length, shoot length and seedling vigour. A talc-based powder formulation ofBurkholderiasp. strain TNAU-1 was developed and evaluated for its efficacy in the management of mung bean root rot under greenhouse conditions. Seed treatment or soil application of the powder formulation ofBurkholderiasp. strain TNAU-1 significantly reduced the incidence of root rot and increased the germination percentage and plant height. Seed treatment with the powder formulation ofBurkholderiasp. strain TNAU-1 alone was effective in controlling root rot disease; but the combined seed treatment and soil application ofBurkholderiasp. strain TNAU-1, increased the efficacy. Seed treatment and soil application withBurkholderiasp. reduced the root rot incidence from 52.6 per cent (with non-bacterized seeds) to 16.7 per cent. Control of root rot with the application ofBurkholderiasp. by seed treatment and soil application was not statistically different from that obtained with seed treatment with carbendazim. The endophytic movement ofBurkholderiasp. in the stem, roots and leaves of mung bean was confirmed through PCR usingBurkholderiasp. specific primers which resulted in the amplification of a 417 bp product.

A field experiment was conducted during rabi season of 2015-2016 at Navsari Agricultural University, Navsari to identify suitable cobalt application method and optimum level for enhancing chickpea yield. There were four cobalt application methods and three levels of cobalt each i.e. seed priming at 0.5, 1.0 and 1.5 ppm, seed treatment at 1, 2 and 3 g kg-1 seed, soil application at 50, 100 and 150 g ha-1, foliar application at 0.01, 0.025 and 0.05% and one control with water priming and one without seed treatment were evaluated in randomized block design with three replications. In general least level of all methods has recorded highest growth and yield of chickpea. As cobalt levels increased, growth and yield of chickpea was decreased linearly in all methods. Soil application of 50 g CoCl2 ha-1 produced highest seed yield hence this treatment can be recommended for higher seed yield and can be useful for succeeding crop.

Soil applications with poultry refuse, cocodust, vermicompost, ash, sawdust, khudepana, cowdung, solarized sand, Trichoderma harzianum and or with seed treatment by T. harzianum were evaluated against damping off disease complex of potato and chilli. All the treatments significantly reduced percent damping off over control. T. harzianum treated seed along with soil treatment with T. harzianum performed best in terms of seed germination, percent damping off reduction and enhanced growth characters than soil application with T. harzianum alone. The experiment indicates that seed treated with T. harzianum then sown in different soil amendment applied seed bed performed better in all parameters than only application with soil amendment. Among the different soil amendments, poultry refuse and vermicompost have promising impact on seed germination, reduction of percent damping off and growth of potato and chilli seedlings when applying along with T. harzianum.

To study the impact of vermicompost, arbuscular mycorrhizae and FYM application on the rice ecosystem at low land, a field experiment was conducted with rice CO(R) 51 at the Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University in Coimbatore during the winter of 2020. The experiment was framed in Randomized Block Design comprising of 8 treatments viz., Recommended Dose of Fertilizer Soil Test Crop Response approach (T1), RDF 75 % + Farm Yard Manure @ 12.5 t ha-1 (T2), T2 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T3), RDF 75 % + Vermicompost @ 5 t ha-1 (T4), T4 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T5), FYM @ 12.5 t ha-1 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T6), Vermicompost @ 5 t ha-1+ Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T7) and Absolute control (T8) and replicated thrice. The maximum microbial population were registered in the plots that received integrated nutrient application of RDF 75 % STCR approach + Vermicompost 5 t ha-1 + seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi. Rice root architecture has changed significantly as a result of mycorrhizal inoculation. Mycorrhizal rice plants have more root volume, length, and spread than plants without mycorrhizae. Nutrient retention and availability influenced the presence of microbial-mediated metabolic activities and nutrient transformations during crop growth. Bacteria, fungus, and actinomycetes became less abundant as the crop reached harvest. The population density of mycorrhizospheres that utilize both organic and inorganic fertilizers is higher. The treatments that received Vermicompost or FYM with Vesicular Arbuscular Mycorrhizae and Nitrogen, Phosphorous & Potassium fertilizers obtained the highest yields of rice grain and straw (6740 and 7840 kg ha-1) respectively, and it was clear that the combination of Vermicompost or FYM, VAM and along with NPK fertilizers produced significantly higher yields than their individual applications and absolute control.

Root rot caused by Rhizoctonia solani is an important disease of mothbean, under severe infestation it causes 58-68 % losses in grain yield. Three-year field experiments were conducted in hot arid conditions at Bikaner, Rajasthan during kharif seasons with the objective to find out suitable eco-friendly management strategies for root rot. The experiment was conducted on cv. RMO-225 with six different combination of Trichoderma harzianum + Pseudomonas fluorescens bio- agents viz, seed treatment, soil treatment and their combinations against the root rot disease and compared with an untreated control. Results of experiment showed that all the treatments brought significant decline in disease incidence and consequently enhancement of grain yield compared to control. The treatment having combination of Trichoderma harzianum + Pseudomonas fluorescens seed treatment (4+4 g/kg seed) + soil application of T. harzianum + P. fluorescens (1.25 +1.25 kg in 50 kg FYM for each/ha) had minimum (21.78 %) root rot incidence, highest grain yield (10.56 q /ha) and net return (Rs. 14,338/ha). The T. harzianum seed treatment 8 g/kg seed + soil application of T. harzianum 2.5kg in 100 kg FYM/ha was the next best treatment with 25.56 per cent disease incidence and 9.42 q/ha of grain yield. These treatments can provide an effective, economical and eco- friendly management of root rot of mothbean for cultivators.
