Maize is the most important crop in Mexico, being central to the diets of consumers, particularly smallholders, and an undetermined amount is allocated as straw, green fodder, and, to a lesser extent, as silage for animal feed. Nitrogen fertilizer is considered one of the most important factors affecting growth, grain yield, and maize biomass production. In this context, the main objective of this study was to evaluate the effects of different levels of nitrogen fertilizer on maize production. A randomized complete block experimental design consisted of three treatments of nitrogen (180, 160, and 80 kg/ha) with three replications and morphological (plant height, stem thickness, and rate of growth), yield, and yield components (cob weight, length, thickness, number of rows per cob, and plant biomass) variables were used. The results suggest that the increase in nitrogen levels increases all the parameters of maize production. However, at 160 kg/ha, the greatest production of fodder was recorded with 5.99 tons/ha, superior to the one reported at 180 kg/ha, which was 5.47 tons/ha. We conclude that the maize fodder production can be optimized with the use of 160 kg/ha in the conditions of the altiplano of San Luis Potosí (Mexico).

Background: In north-eastern Thailand, sugarcane is planted normally in late rainy season wherein the plants may experience drought stress during its early growth stage in dry season and waterlogging stress during late growth stage at peak of rainy season. Hence, the objective of the present study was to investigate the effects of soil application alone and soil combined with foliar application of nutrients on growth, yield and sugar quality of sugarcane grown under rainfed conditions. Methods: The field experiment was conducted during November 2016 to December 2017. A split-plot design with three replications was laid out. The two sugarcane cultivars (KK3, K93-219) were assigned as main plots. The fertilizer application methods were assigned as sub-plots that comprised of four treatments: (1) soil applied NPK, (2) soil NPK + foliar N and K applied at 90 days after planting (DAP), (3) soil NPK + foliar N and K applied at 210 DAP and (4) soil NPK + foliar N and K applied at 90 and 210 DAP. Result: The soil NPK + foliar N and K applied at 90 and 210 DAP improved yield components and cane yield. The cultivar K93-219 produced significantly higher cane yield than KK3. The fertilizer application methods and cultivars had no significant effect on sugar quality such as brix (%), purity (%), polarity (%), fiber (%) and commercial cane sugar (CCS-%).

Crop plants are more often exposed to abiotic stresses in the current age of fast-evolving climate change. This includes exposure to extreme and unpredictable changes in climatic conditions, phytosanitary hazards, and cultivation conditions, which results in drastic losses in worldwide agricultural productions. Plants coexist with microbial symbionts, some of which play key roles in the ecosystem and plant processes. The application of microbial biostimulants, which take advantage of symbiotic relationships, is a long-term strategy for improving plant productivity and performance, even in the face of climate change-associated stresses. Beneficial filamentous fungi, yeasts, and bacteria are examples of microbial biostimulants, which can boost the growth, yield, nutrition and stress tolerance in plants. This paper highlights recent information about the role of microbial biostimulants and their potential application in mitigating the abiotic stresses occurring on crop plants due to climate change. A critical evaluation for their efficient use under diverse climatic conditions is also made. Currently, accessible products generally improve cultural conditions, but their action mechanisms are mostly unknown, and their benefits are frequently inconsistent. Thus, further studies that could lead to the more precisely targeted products are discussed.

Recently, the use of biostimulants as natural and eco-friendly fertilizers has received increasing attention because of their efficiency in terms of improving crops’ qualitative and quantitative parameters, i.e., growth, yield, and chemical composition. We studied the effect of four biostimulants—humic acid (20 g/L), vermicompost tea (15 mL/L), moringa leaf extract (1:30 v/v), and yeast extract (5 g/L), with tap water as a control treatment—on the qualitative and quantitative characteristics of snap beans. The experiment was designed using a complete randomized block with triplicates. The results showed a significant improvement in treated plant performance (growth and yield), chlorophyll, and chemical composition compared to untreated plants. Using moringa leaf extract increased the plant height, number of leaves and branches/plant, and fresh and dry weight. Additionally, the diameter of the treated plant stems and the quality of the crop and pods were also significantly higher than those of plants treated with vermicompost or humic acid extract. It is also noted that the profile of amino acids was improved using all tested biostimulants. This leads to the conclusion that the addition of moringa leaf extract and vermicompost tea not only positively affects the qualitative and quantitative properties of snap bean but is also reflected in its nutritional value as a plant-based food.

Rice–wheat (RW) rotation is the largest agriculture production system in South Asia with a multifaceted role in maintaining the livelihood of people. The customary practices and indiscriminate use of synthetic fertilizers have culminated in the decline of its productivity and profitability during the past two decades, thus affecting the sustainability of wheat. Safe Rock® Minerals (SRM) is a multi-nutrient rich natural rock mineral with great potential to manage soil degradation, reducing the input of fertilizers, improving soil fertility, and plant health. Thus, a field trial was conducted at the research farm of ICAR—Indian Agricultural Research Institute, New Delhi from 2016 to 2018 to evaluate the impact of Safe Rock® Minerals (SRM) on biometric parameters, productivity, quality, and nutrient uptake by conventional wheat and System of Wheat Intensification (SWI) in the wheat–rice cropping system. The results indicate that SWI performed better in terms of growth, yield, and quality parameters than conventional wheat. Among nutrient management practices; the highest growth, yield, and yield attributes of wheat were achieved with the use of SRM application 250 kg ha−1 + 100% Recommended Dose of Fertilizer (RDF). SRM application also increased grain protein content significantly. In conclusion, the integrated use of SRM with organic manures can serve as an eco-friendly approach for sustainable wheat production.

Background: Dryland is characterised by drought/dry spell (s) of 10 to 15 days and is the main reason for decline in soybean production. The aim of this study was to develop a strategy of drought amelioration by using foliar sprays and enhancement of yield, quality, energetics and carbon footprint. Methods: A field experiment was carried out at Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, College of Agriculture, Indore, (M.P.) during 2017-18 under spilt-plot design having two main plot treatments viz., foliar application at dry spell (F1), foliar application after dry spell (F2) and seven sub plot treatments i.e. different variants of foliar sprays (DVFS). Different growth, yield, quality, energetic and carbon footprint traits were recorded. The data were analyzed using standard statistical procedures. Result: The highest growth, yield, quality and energetic parameters were recorded for F1 as compared to F2. In case of DVFS, foliar application of water soluble complex fertilizer 19:19:19 (NPK) @ 0.5% + 0.5% ZnSO4 (T4) produced maximum values for growth, energetics, carbon footprint, oil (22.5%) and protein (43.1%) content as well as produced maximum yield.

A pot experiment was set up using completely randomized design (CRD) to compare the influences of different commonly available organic manures in the markets of Dhaka, Bangladesh on the growth parameters and nutrient contents in Mint plants (Mentha sp.). Eight different manures were used as treatments for the comparison, viz. ACI, Alo, Annopurna Vermicompost, Cow dung, Kazi, Mazim, Modern Vermicompost and Trichocompost GBD, along with a control, taking three replications of each treatment. After 2.5 months (75 days) the plants were harvested. Trichocompost GBD showed the highest average number of leaves (130.33 plant-1), plant height (27.67 cm plant-1), number of branches (11.00 plant-1) and number of stolons at harvest (1.67 plant-1). The maximum average single leaf area (2.01 cm2 plant-1) and fresh weight (1.68 g plant-1) were observed in Kazi. ACI was observed to have the highest dry weight (0.26 g plant-1), whereas cow dung had the longest root (8.57 cm plant-1). Nutrient accumulation in leaf and stem exhibited the highest N in ACI, highest P and K in Alo, and highest S in Kazi. Correlation analysis of the explored traits with nutrient concentration of plant shoots was performed to elucidate the impact of plant nutrient contents on the analysed parameters. J. Biodivers.
