“…In this regard, the biochar amendment is a viable strategy together with N fertilization. N application is key for increasing crop yields and biomass production (Ali, Khan, Imran, et al, 2019;Ali, Khan, Munsif, et al, 2019;Belete, Dechassa, Molla, & Tana, 2018;Lee, Wycislo, Guo, Lee, & Voigt, 2017).…”

Biochar and inorganic fertilizer when co‐applied have been reported to increase crop yield and enhance soil fertility. However, studies on this complementary effect on soil properties and noodle rice performance in China are still scanty. To investigate the effects of biochar application coupled with inorganic fertilizers on soil sustainability and yield and yield attributes of noodle rice, outdoor pot experiments were conducted in the early and late growing seasons in 2018. The treatment combinations were T1 (B0 t/ha + N270 kg/ha), T2 (B20 t/ha + N270 kg/ha), T3 (B40 t/ha + N270 kg/ha), T4 (B60 t/ha + N270 kg/ha), T5 (B0 t/ha + N360 kg/ha), T6 (B20 t/ha + N360 kg/ha), T7 (B40 t/ha + N360 kg/ha), and T8 (B60 t/ha + N360 kg/ha). The results compiled across the seasons showed an increase in Pn (net photosynthetic rate), grain yield, N uptake, gel consistency, amylose content (AC), and protein content in biochar‐treated pots as compared to T1. Average increases of 63.24, 63.66, 14.85, 58.0, 59.0, 22.39, and 2.9% were observed in soil porosity, moisture content, pH, organic carbon, total nitrogen, available phosphorus, and available potassium in T4 over T1 across the seasons, respectively. Root morphological characteristics such as total root length, surface area, volume, and average root diameter were significantly improved in T3, T4, T7, and T8. Starch‐related enzymes such as starch branching enzyme (SBE), starch debranching enzyme (DBE), and soluble starch synthase (SSS) were not affected significantly; however, granule‐bound starch synthase (GBSS), ADP‐glucose pyrophosphorylase (ADPG), and starch synthesis (SS) enzyme showed higher activity in 40 and 60 t B/ha across N rates. Conclusively, biochar application of 60 t/ha along with 270 kg N/ha is a promising option for improving soil quality and increasing photosynthesis, yield, and yield attributes of noodle rice.

Greengram (Vigna radiata L.) being a leguminous crop has high nutritional value and is one of the most important pulse crops grown in India. In India greengram production is affected by a variety of factors, including biotic stresses like diseases, weeds, and pests as well as abiotic stresses such as drought, floods and poor management practices. Among those the use of inorganic fertilizers has resulted in ground water pollution, deteriorating soil quality, high production cost and poor quality production for livelihood which has resulted in poor productivity. Thus the main objective of this paper is to review the use of organic extracts and fertilizers and their benefits for enhanced productivity in greengram. As organic sources are known to considerably effect the growth and development of a crop yielding significant results, as a result utilization of such organic sources like seaweed extract, vermiwash, humic acid, panchagavya and jeevamruth can play a major role in enhancing the productivity in greengram.

“…It acts as a growth promoter and helps in the nutrient uptake of crops as well as increased yield of vegetables [14,15]. It can increase cell membrane permeability, respiration, and photosynthesis [16], root cell elongation, and phosphate uptake in plants under abiotic stress [17,18]. Similarly, Selenium (Se) is a trace mineral that animals and humans need as a micronutrient [19].…”

Maximizing food production under adverse conditions is a major challenge to food security and sustainability in the face of population growth and climatic change. The use of amendments applied as a supplement under adverse conditions may play a significant role in the mitigation of biotic and abiotic stress. This study aimed to explore the morpho-physio-biochemical changes in chili in response to cadmium (Cd) stress. The present study investigated the effects of foliar-applied selenium (Na2SeO4) (3 µM) and soil-applied humic acid (250 mg kg−1 w/w soil) in the sole and synergistic form under varying levels of cadmium stress (0, 2, and 4 mM using CdCl2) in chili. Results revealed that a linear decrease was noticed in the growth, biomass, and phenological attributes of chili plants by increasing the Cd stress. More reduction was noticed at the higher levels of Cd stress as compared to control due lowering plant dry weight (18.15 and 39.67%), relative water content (RWC) (10.73 and 24.17%), total chlorophyll concentrations (16.01 and 31.44%) and increased electrolyte leakage (49.44 and 129.35%) and malonaldehyde contents (MDA) (68.41 and 104.04%). Dry biomass significantly increased with humic acid and selenium treatments, regardless of cadmium level. The reduced enzymatic activities associated with reactive oxygen species (ROS) detoxification, underscores the pivotal role of Se and humic acid in maintaining redox homeostasis. The combined effect of selenium and humic acid proved better results as compared to the sole application in minimizing Cd uptake in roots and fruit. This study demonstrates that the application of humic acid and selenium activates physio-biochemical defense responses against cadmium stress in chili plants and provides significant pavement for the cultivation of chili in cadmium-containing soils with a target of high-yielding and quality.
