Abstract

The preparation of enriched formulation by integrating of agricultural wastes such as paddy husk ash (PHA) and potato peel with organic fertilizer such as farmyard manure (FYM), compost can enrich the soil with essential plant nutrients, leading to higher yields in subsequent crops and potentially reducing the dependence on farmyard manure/compost alone. However, there is lack of adequate research findings regarding the impact of different formulations generated from agricultural waste on productivity, nutrient utilization efficiency and profitability of baby corn-kabuli gram-vegetable cowpea cropping system. Therefore, a two-year field experiment (2020–2022) was conducted ICAR-IARI, New Delhi with baby corn-kabuli gram-vegetable cowpea cropping system. Seven nutrient sources were tested in Randomized Block Design and replicate thrice.The results showed that treatment T4 (100% recommended dose of nitrogen (RDN) through PHA based formulation) had significant effect on crop yield grown in rotation, followed by treatment T6 (100% RDN through potato peel compost (PPC) based formulation) and T2 (100% RDN through FYM). The increase in yield was 75.0, 44.3 and 33.1% during first year and 72.6, 45.9 and 31.0% during second year, respectively, over control. Treatment T4 also significantly enhanced system uptake of N, P and K as well as system gross returns and net returns, resulting in 65.6, 84.9, 69.5, 50.7 and 55.2% higher returns during first year and 68.6, 80.5, 73.9, 50.0 and 54.2% higher returns during second year, respectively, over control. Furthermore, treatment T4 significantly improved agronomic nitrogen use efficiency and apparent recovery by 151.6 and 2.0% in baby corn, 74.2 and 1.5% in kabuli gram, 55.7 and 13.9% in veg cowpea over T7, respectively, averaged across two years of study. Based on these results, it is recommended to adopt (T4) 100% RDN through PHA based formulation, and (T6) 100% RDN through PPC based formulation in the area with a shortage of FYM

Abstract

In the present study, we studied the distribution of silicate mineral weathering bacteria (SWB) in stressed environments that release potassium from insoluble source of mineral. Out of 972 isolates, 340 isolates were positive and mineral weathering potential ranged from 5.55 to 180.05%. Maximum abundance of SWB occurred 44.71% in saline environment followed by 23.53% in low temperature and 12.35% each in high temperature and moisture deficit. Among isolates, silicate mineral weathering efficiency ranged from 1.9 to 72.8 μg mL−1available K in liquid medium. The phylogenetic tree of SWB discriminated in three clusters viz. Firmicutes, Proteobacteria and Actinobacteria. This is the first report on SWB in stressed environments and identified 27 genera and 67 species which is not reported earlier. Among them Bacilluswas the predominant genera (58.60%) distantly followed by Pseudomonas(6.37%), Staphylococcus(5.10%) and Paenibacillus(4.46%). These bacterial strains could be developed as inoculants for biological replenishment of K in stressed soils.

Abstract

In the present investigation, five strains of Janthinobacteriumobtained from Rohtang Pass, Himachal Pradesh, India along with one strain of Bacillus decolorationis(IARI-SL-13) were screened qualitatively and quantitatively for their ability to solubilize K at different temperatures ranging from 5 to 30 °C. All the selected strains do not produce violet colonies, instead produced pink or red coloured colonies. In a plate assay, among all the strains tested, Janthinobacteriumsp. IARI-R-81 was most efficient in solubilization of K at lower temperatures of 5 and 10 °C and was closely followed by Janthinobacterium lividum(IARI-R-71). Janthinobacteriumsp. IARI-R-70 did not produce any detectable halo zones at all temperatures except 10 and 25 °C. Quantitative analysis revealed that all the selected pigment-producing strains could solubilize potassium-bearing mineral at low temperature (5 °C). J. lividumIARI-R-50 strain was most efficient in solubilizing K (29.87 ± 1.22 µg K/mL) from its mineral at 5 °C. This strain was typical as it solubilized almost the same amount of K both at 5 and 30 °C indicating its capability to adapt to different temperatures. All other strains showed a significantly higher concentration of solubilized K at 30 °C as compared to other temperatures tested. The non-pigmented B. decolorationisshowed solubilization only at 25 and 30 °C and the concentration of K solubilized at 30 °C was significantly higher than at 25 °C. There was no correlation between pigment production and solubilization of potassium. This is the first report depicting solubilization trait of members of genus Janthinobacteriumand confirms its evolutionary relatedness to Collimonads.

Abstract

A new spectrophotometric method was developed for the quantification of potassium in the culture broth supernatant of K-solubilizing bacteria. The standard curve of potassium with the new method, which is based on the measurement of cobalt, showed a regression coefficient (R2) of 0.998. The quantification values of potassium obtained with flame photometric method and the newly developed method showed a significant correlation (r) of 0.978. The new method depends on the precipitation of sodium cobaltinitrite with solubilized potassium in liquid medium as potassium sodium cobaltinitrite, which develops bluish green colour by the addition of conc. HCl. The intensity of developed colour can be recorded at 623 nm. This method involves less number of steps, is easy and time saving, and can be used for the reliable estimation of available potassium in culture broth supernatant of K-solubilizing bacteria.
