Probiotics for Sustainable Agriculture: Prospects and Challenges

Paper ID- AMA-01-06-2022-11426

The combined influence of conventional agricultural practice and booming population, entice the advanced research on sustainable agriculture. The basic goal of sustainable agriculture includes environmental health, social & economic equity and economic viability, which can be achieved by supplementation of plant probiotics. It will not only fulfil the prime goals of sustainable agriculture but also enhance microbial biodiversity in soil. These latent microbes when applied to host plants, colonize independently or as endophytes and are potentially involved in plant growth promotion, nitrogen fixation, siderophore production, phosphate solubilization and biocontrol activities. Additionally, they have a unique property to break down the complex nutrients into simpler ones thereby improving the soil fertility. The phytobiomes act as an eco-friendly substitute for chemical fertilizers as it promotes plant health, growth & productivity along with soil health leading to organic farming. Hence, this review put forth views pertaining to the traits and applications of potent plant probiotics for sustainable agriculture.

Effect of Phosphorus Activators on Increasing Legacy Phosphorus Availability for Maize Growth in Calcareous Soil

Paper ID- AMA-31-05-2022-11424

Soil legacy phosphorus (P) accumulated due to the long-term continuous application of phosphatic fertilizers in agricultural fields retained in the soil for years, as they are sparingly soluble. This can be made as a possible soil P source using phosphorus activators. In this study, a laboratory incubation and a pot experiment was conducted to evaluate the potential of some P activators (Phosphorus Solubilising Bacteria, Phytase, Humic acid, Oxalic acid, Farmyard Manure) in increasing the availability of residual phosphorus in calcareous soil. For incubation experiment, the P activators were applied alone and combined. Soil samples were analyzed at subsequent intervals for Olsen P, alkaline phosphatase activity, and sequential P fractions. The results showed that Farmyard Manure (FYM) application with Humic acid (HA) increased the available soil phosphorus and alkaline phosphatase activity. All treatments have a significant effect on different soil P-fractions. A greater reduction in calcium phosphate fraction was noted in FYM and Humic acid application. The best five treatments selected from the laboratory incubated experiment were used for the pot experiment with maize, along with the different dosages of P fertilizer. The morphological parameters were observed on 30th and 60th days of the maize crop. The results show that the application of FYM and Humic acid with 100% recommended dose of P was statistically comparable with FYM and Humic acid with 75% recommended dose of P. The findings have illustrated the potential mechanisms of P release by different P activators and the efficiency of P activators in increasing the legacy P availability.

Screening of Mungbean [Vigna radiata (L.) Wilczek] germplasm for Cercospora leaf spot resistance

Paper ID- AMA-31-05-2022-11422

Ninety mungbean [Vigna radiata (L.) Wilczek] germplasm accessions were evaluated for resistance against leaf spot disease caused by Cercospora canescens under field conditions during rabi 2018 and rabi 2019. A disease rating scale of 1-5 was used for the evaluation of resistance of mungbean accessions. A considerable variation was found among the genotypes with respect to the disease reaction. Thirty-two accessions; were found resistant and thirty-five accessions were found to have moderately resistant reactions against the CLS disease. The rest of the accessions were either susceptible or moderately susceptible or highly susceptible. On the basis of present investigations, resistant and moderately resistant genotypes identified against CLS disease may be exploited in the breeding program aimed at the development of a high-level resistant variety of mungbean against Cercospora leaf spot.

Response of salicylic acid and triacontanol on quality of ber (Ziziphus mauritiana Lamk) cv. Gola

Paper ID- AMA-30-05-2022-11419

A field experiment entitled “Response of Salicylic acid and Triacontanol on Quality of Ber (Ziziphus mauritiana Lamk) cv. Gola” conducted during 2020-21 at instructional Farm, Department of Horticulture, College of Agriculture, Ummedganj (Agricultural University, Kota). It consisted of 16 treatment combinations with four levels of salicylic acid (control, SA @ 100, 150 and 200 ppm) and four levels of triacontanol (control, TRIA @ 5.0, 7.5 and 10.0 ppm) and replicated thrice in Factorial Randomized Block Design. The application of salicylic acid @ 150 ppm among the different concentrations proved significantly superior over rest of the treatments in respect to quality parameters viz- maximum chlorophyll content in leaves (3.86 mg/g), nitrogen content (1.84%), phosphorus content (0.33%), potassium content (1.57%), TSS (18.48O Brix), minimum acidity (0.389%), maximum TSS:Acidity ratio (47.90), highest ascorbic acid content (102.28 mg/100g), reducing sugar (5.11%), non-reducing sugar (4.36%) and maximum total sugar (9.70%) and at par with the treatment T3 (10.0 ppm triacontanol) and found lowest in the control.

Productivity and profitability of pigeon pea–vegetable mustard–okra cropping system as influenced by enriched organic formulations in a semi-arid agro-ecology

Paper ID- AMA-29-05-2022-11417

A field experiment was conducted during the rainy (kharif), winter (rabi) and summer seasons of 2020–21 and 2021–22 at the research farm of Indian Agricultural Research Institute, New Delhi to evaluate the productivity and profitability of pigeon pea–vegetable mustard–okra cropping system as influenced by enriched organic formulations. The experiment comprised of one cropping system (pigeon pea–vegetable mustard–okra) and seven nutrient sources viz., control, 100% RDN through FYM, 100% RDN through improved RRC, 100% RDN through PHA enriched FYM, 75% RDN through PHA enriched FYM, 100% RDN through PPC enriched FYM and 75% RDN through PPC enriched FYM were tested in randomized block design with three replications. Results showed that the apparent values of yield of the crops were influenced by enriched organic formulations during both the years. Among the treatments, application of 100% RDN through PHA enriched FYM gave significantly highest seed and stover yield, followed by 100% RDN through PPC enriched FYM and FYM during both the years of study. System productivity of cropping system in terms of pigeon pea-equivalent yield (PPEY) was significantly higher under 100% RDN through PHA enriched FYM (8.70 and 8.97 t ha-1) during both the years of experimentation. Results further revealed that the same treatment resulted into statistically highest system gross returns, net returns and B:C ratio (₹671.7 x103 ha-1 and ₹689.6 x103 ha-1; ₹553.6 x103 ha-1 and ₹567.8 x103 ha-1; 4.96 and 4.94 during 2020–21 and 2021–22, respectively) over other nutrient sources and remained at par with 100% RDN through PPC enriched FYM and FYM during both the years.
