“…Indian agriculture generated approximately 696.38 million tons (Mt) per year of crop residues [1] either left in the agricultural field or orchard after harvested residues (stalks, stubble, leaves, and seed pods) or left after the crop residues (molasses and sugarcane bagasse) [2,3], and out of these about 85 Mt of crop residues are burnt on-farm as per estimated by the Indian Ministry of New and Renewable Energy [4,5] and Inter-Governmental Panel on Climate Change [6,7]. Among all the crops, corn (Zea mays L.) is one of the most versatile crops having the highest genetic yield potential, wider adaptability under diverse agro-climatic conditions [8], and a variety of food and industrial products [9][10][11]. Globally, corn is known as the queen of cereals because it has been cultivated in over 170 countries Sustainability 2022, 14, 16605 2 of 14 with 1219.76 million tons of grain production [12], and it emerged as a potential remunerative crop, especially among progressive farmers in India.…”

Corn stalk fibers were extracted from corn stalk using sodium hydroxide for textile application. The extraction conditions were optimized on the basis of the quality and quantity of extracted fibers. The optimum conditions were obtained by treating corn stalk with 5 g/L concentration of sodium hydroxide for 60 min at boiling temperature using a 1:50 material-to-liquor ratio. Extracted fibers were bleached and tested for different physical and chemical properties. Besides these properties, the characterization of extracted fibers was carried out by a scanning electron microscope (SEM), X-ray diffraction analysis (XRD) and Fourier–transform infrared (FTIR) analysis. SEM was used to study the morphological changes in the raw and bleached fibers. The crystallinity changes of the raw and bleached samples were measured with an X-ray diffractometer by peak height method. FTIR was used to examine the compositional changes in the bleaching process. It was found that raw fibers contained the cellular residues such as lignin and hemicelluloses, which cement the fibers together. The chemical treatments such as alkali and bleaching partially removed hemicelluloses, lignin, and amorphous fractions of cellulose. This led to the gradually increasing crystallinity of the treated fiber. Peak height values were obtained by measuring the transmittance of the spectra through FTIR analysis. Different physical and chemical properties of the extracted corn stalk fibers indicated that it can be used for making biodegradable composite materials.

“…Soil health and plant productivity are severely affected by various interactions between plants, 2 of 20 soil, and microorganisms [2]. Among the available crops, corn (Zea mays L.) is one of the most diverse crops, with high genetic potential and extensive adaptation to different agroclimatic conditions [3]. It is the source of numerous food and industrial products [4][5][6].…”

Corn (Zea mays L.) is an important annual grain that is cultivated as a food staple around the world. The current study examined the effect of wastewater and a combination of biological and organic fertilizers on the morphological and phytochemical traits of corn, using a factorial experiment based on a randomized complete block design with three replications. The first factor was biological and organic fertilizers at seven levels, including the control (no fertilization), bacterial biological fertilizers (NPK) along with iron and zinc Barvar biofertilizers, fungal biofertilizers made from Mycorrhiza and Trichoderma, biochar, a combination of bacterial and fungal biofertilizers, and a combination of bacterial and fungal biofertilizers with biochar. The second factor was irrigation at two levels (conventional irrigation and irrigation with wastewater). The traits studied included the morphological yield, phenols, flavonoids, polyphenols, glomalin, cadmium content in plant parts, and translocation factor (TF). The results disclosed that the best treatment in regard to the morphological traits was related to conventional water + biochar + mycorrhiza + Trichoderma + NPK. The highest phenol and flavonoid content were observed when biochar + mycorrhiza + Trichoderma + NPK treatments were used in both water treatments. Also, the wastewater + biochar + mycorrhiza + Trichoderma + NPK treatment demonstrated the highest total glomalin and phenylalanine ammonia-lyase (PAL) activity. The obtained results demonstrate that combined biological and organic fertilizer use on corn plants can effectively alleviate the deleterious effects of cadmium present in wastewater.

In Nepal, the productivity of maize is very low in comparison with developed countries. The use of hybrid varieties with proper nutrient management helps to unlock the high yielding potential of maize. So, the experiment was conducted at Fulbari, Dang, Nepal from June 30, 2019 to October 16, 2019 to find the yield performance of two maize varieties (Local and Hybrid) under different nutrient management. The study was conducted in factorial randomized complete block design with three replications and eight treatments. Treatments consist of different combinations of two maize varieties (Local and hybrid) and four different nutrient management practices. Significant effects of Nutrient management were observed on plant height, l eaf area index (LAI), kernels per row, kernels per cob maize, test weight, biological yield, economic yield and harvest index of maize. Similarly, significant effects of varieties was observed on plant height, leaf number, LAI, cob length, kernel rows per cob, kernels per kernel row, kernels per cob maize, test weight, biological yield, economic yield and harvest index of maize. Interaction effect of Nutrient management and varieties was found significant on LAI, kernel rows per cob, kernels per kernel row, kernels per cob maize, test weight, biological yield, economic yield and harvest index of maize. The overall performance of hybrid maize under Leaf color chart (LCC) based nutrient management was found better than other treatments. Therefore, production of Hybrid maize under LCC based nutrient management is suggested. Int. J. Appl. Sci. Biotechnol. Vol 8(2): 191-198
