    Abstract Purpose Chicken eggshell (ES) is a global biowaste product of poultry industry and an enriched source of calcium required for plant growth. Therefore, the present study has been carried out to assess the potentiality of the combination of ES with vermicompost (VC) and chicken feather protein hydrolysate (CFPH) on growth and yield improvement of Capsicum plants.Method A field study was conducted through randomized block design (RBD) with eight treatments having three replicates for each. Principle Component Analysis (PCA) have performed to analyze the yield related parameters of plant. Nutritional components of VC and ES were also analyzed.Results The PCA analysis of the field experiment data has indicated that the combination of ES, CFPH and VC (in a ratio of 100:10:3) remarkably increased the agronomic parameters of capsicum plant about four folds as compared to its chemical counterpart and control, while together VC and ES strongly influences the characteristics of fruits. The first two dimensions of first and second PCA analysis showed 88.39 and 66.91 percent of the overall dataset inertia respectively, explaining 88.39 and 66.91 percent of the total variability. These two values are higher than their respective reference values of 36.32 and 46.76 percent indicating substantial variability.Conclusion The co-application of ES, CFPH with VC could enhance the yield parameters of crops by enriching the soil with both micro and macronutrients. It also serves as a source of organic compost with concomitant reduction in the use of chemical fertilizers.

    Abstract Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH for its absorption by plants is about 6.5, but in alkaline and acidic soils, most of the consumed P forms an insoluble complex with calcium, iron, and aluminum elements and its availability for absorption by the plant decreases. The supply of P needed by plants is mainly achieved through chemical fertilizers; however, in addition to the high price of these fertilizers, in the long run, their destructive effects will affect the soil and the environment. The use of cheap and abundant resources such as rock phosphate (RP) can be an alternative strategy for P chemical fertilizers, but the solubilization of P of this source has been a challenge for agricultural researchers. For this, physical and chemical treatments have been used, but the solution that has recently attracted the attention of the researchers is to use the potential of rhizobacteria to solubilize RP and supply P to plants by this method. These microorganisms, via. mechanisms such as proton secretion, organic and mineral acid production, siderophore production, etc., lead to the solubilization of RP, and by releasing its P, they improve the quantitative and qualitative performance of agricultural products. In this review, addressing the potential of rhizosphere microbes (with a focus on rhizobacteria) as an eco-friendly strategy for RP solubilization, along with physical and chemical solutions, has been attempted.

    Abstract Purpose Chicken feather protein hydrolysate (CFPH) has drawn a significant attention as a component/type of biofertilizer in recent years, because of the beneficial impact on the growth of the plant. The current study aims to evaluate the potential influence of the combination of CFPH with vermicompost (VC) on growth-promotion and yield improvement in tomato plants. Method Feather degrading bacteria were isolated and characterized using 16s-rDNA sequencing, and assessed for biochemical reactions, growth-promoting attributes and keratinase activity. The medium used for feather degradation studies consisted of 0.75% (w/v) of raw feather, with 1% (v/v) of inoculum at 37°C, pH 7.5 and at 120 rpm. A field study was done by randomized block design (RBD) with five treatments in tomato. Results Keratinolytic and feather degrading bacteria isolated and used in this study were identified as Bacillus cereus PKID1 with accession number MT158702. The bacterium gave the highest keratinase activity of 80±0.28 U/ml. The CFPH showed the potential to promote remarkably the germination % of tomato (84.13), rice (87.24), onion (84.13), chilli (84.13), chickpea (73.24) seeds

    field experiment significantly increased plant growth and yield compared with control. Conclusion The principal component analysis of the field experiment as a result of tomato plant-growth, the order of best treatment efficacy for improvement of parameter estimates was as follows: CFPH and VC > CFPH > VC > recommended dose of fertilizers (RDF) > control. Thus, the application of CFPH with VC could improve the productivity of crops and decrease the use of chemical fertilizers.
