Enrichment of the Waste Effluents of Handmade Paper Industry for Biofertilizer Use in Green Chili Plants

Research Square (Research Square) (2024)

Satya Narayana Mathur Rajesh Rahul Mishra Sunita Chauhan

Abstract Effluents pose a great concern for each and every industry including the paper mills. The effluents of papermaking industry need attention due to their dark colors and alkaline nature which on disposal may destroy the biodiversity and aesthetic value of any water body. Due to the non-woody raw materials with minimum chemicals, effluents of handmade paper industry are rich in organic matter and less toxic and less harmful compared to the conventional paper mills. Therefore, the present study was taken up with an aim to utilize effluents of handmade papermaking from cow dung as liquid biofertilizers. For this, the effluent was enriched with selected Plant Growth Promoting Rhizobacteria (PGPR) and then used to study its plant growth promoting traits with the seeds of NU1919 variety in Green chilli (Capsicum frutescens) plants using four treatments in triplicates with the Random Block Design. The results of plant growth promotion (viz. number of fruits per plant, average pedicel, average fruit length, fruit yield per plant and average plant height) were found to be best in Set D where a consortium of Azotobacter sp and Enterobacter sps was used along with un-autoclaved effluent (RL). However, average girth and average fruit weight (fresh and dry weight) were maximum in Set B where Azotobacter and Bacillus megaterium were used for modifying RL. On analysis of biochemical attributes of chilli harvest, Vitamin A was found to be maximum in the case of Set A where RL (as such) was used as a biofertilizer, whereas, Vitamin C was found to be almost equal in Set A (167.79 mg/100gm) and Set D (167.30 mg/100gm). The Set C (Bacillus + Azotobacter) showed maximum capsaicinoid content (67,793.18 SHU). Thus the handmade paper industry effluents have been found to be suitable for their biofertilizer use in cultivation of chilli (Capsicum frutescence) plants.

Evaluation of Different Extractants to Estimate Bioavailable Arsenic in Soil

Communications in Soil Science and Plant Analysis (2023)

Rahul Mishra Siba Prasad Datta Debasis Golui Mahesh Chand Meena Bramha Swaroop Dwivedi

Owing to the similar chemistry of phosphorus (P) and arsenic (As), sodium bicarbonate (0.5 N NaHCO3) is commonly used to extract plant accessible As in soil. This extractant has neither been tested widely in relation to plant As, nor is this extractant compatible with inductively coupled plasma mass spectrometry (ICP-MS) due to the high concentration of dissolved solid. Subsequently, it is of utmost important to design a suitable chemical extraction method in order to estimate plant available As compatibility with ICP-MS. For this purpose, paired soil and plant samples were collected from paddy fields located in Nadia, West Bengal, India. Soil was extracted with 0.5 M NaHCO3, 0.1 N and 0.5 N phosphoric acid (H3PO4), 0.1 N and 0.5 N sulfuric acid (H2SO4), 0.1 N, 0.5 N, 1.0 N, 1.5 N HNO3 and 0.01 M calcium chloride (CaCl2) solution. Arsenic extracted with NaHCO3, H3PO4 and H2SO4 was determined in hydride generation-atomic absorption spectrophotometer (HG-AAS), while ICP-MS served to determine As extracted from soil with HNO3. Olsen-extractable As in soils ranged from 0.48 to 3.57 mg kg−1 with a mean value of 1.45 mg kg−1. The extractable As content in soil varied from 0.01 to 10.1 mg kg−1 across the extractants. In the case of grain As, 0.1 N H3PO4, 0.5 N NaHCO3 and 1.5 N HNO3 extractable As had distinctly higher correlation coefficients (r = 0.49**, r = 0.47**, r = 0.45**) when compared to other extractants. More or less similar relationships of extractable As were obtained with straw As content like that of rice grain. In view of rapidity of the soil test method for As, 1.5 N HNO3 can be recommended for assessing available As in soil.

Sulphur in Soils and Plants: An Overview

International Research Journal of Pure and Applied Chemistry (2020)

Ashish Rai Arvind Kumar Singh Rahul Mishra Brajesh Shahi Vikas Kumar

In India food demand is increasingly doubled due to calorie consumption of fast growing population rate. For achieving and sustaining a high level of food production, especially in agriculture, soil must be regularly replenished with a balance of crop nutrients, like macronutrients, secondary nutrients and micronutrients. Sulphur (S) comes under secondary nutrients after nitrogen, phosphorus and potash (potassium) at number four as an essential nutrient. It exists in group 16 and period 3 with a molecular weight of 32 in the periodic table. Naturally S occurs as an element found in many minerals like iron pyrites, galena, gypsum and Epsom salts. In Igneous and Sedimentary rocks S occurs as sulphides and in soil it is also present as organic compounds also in industrial wastes, sea water as well as gaseous emission in the atmosphere. Under temperate conditions it assumes that more than 95% of total S in soil is present in the organic matter due to low decomposition rate. In plants, sulphur plays an important role in protein synthesis.
