Agriculture is the basis of our economic activity. For improving agricultural production greenhouse technology was developed to prevent adverse climatic conditions. Even though higher yield and profit were obtained from greenhouse production compared to open field cultivation farmers were not satisfied with this technique due to the drastic reduction of crop yield with the aging of cladding material. To test this, an experiment was conducted in the instructional farm of Kelappaji College of Agricultural Engineering and Technology (KCAET), Tavanur, Kerala during the period from April to June 2021. Amaranthus variety CO1 was planted inside two greenhouses where one is having cleaned cladding material and the other is an old one. Microclimatic parameters and the biometric observations of crop in both conditions were compared. Mean monthly values of temperature and light intensity were higher inside the cleaned greenhouse than the old one while relative humidity was higher inside the old greenhouse. Crop growth parameters were higher inside the cleaned greenhouse than the old one except the internodal length. From this study, it was clear that the aging of cladding material has a significantly higher influence on crop performance under greenhouse.

Abstract A comparison was made of Canadian sphagnum peat (SP) and Philippine coconut (Cocos nucifera L.) coir dust (CD) as growing media components for greenhouse production of Dracaena marginata Bak. and Spathiphyllum Schott ‘Petite’. Three soilless foliage plant growing mixes (Cornell, Hybrid, University of Florida #2 [UF-2]) were prepared using either SP or CD and pine bark (PB), vermiculite (V), and/or perlite (P) in the following ratios (% by vol): Cornell = 50 CD or SP:25 V:25 P, Hybrid = 40 CD or SP:30 V:30 PB, UF-2 = 50 CD or SP: 50 PB. Dracaena root growth was not affected by treatments but there were significant mix × media component interactions that affected plant top growth parameters. In general, the growth and quality of D. marginata were reduced by using CD in Cornell, had no effect in Hybrid, and increased in UF-2. S. ‘Petite’ grew equally well in all growing mixes regardless of whether CD or SP was used; however, plants grew more in Cornell and Hybrid than in UF-2. S. ‘Petite’ roots, which were infested with Cylindrocladium spathiphylli, had higher grades when grown in CD than when the media contained SP.

Indian mustard (Brassica juncea L. Czern) cultivation is suggested for regions with short seasons and low rainfall. Although there have been many studies conducted on agronomic production of mustard in Iran, the information regarding the interactive impact of cropping seasons and nitrogen fertiliser on growth characteristics and yield quality of mustard plant is still insufficient and requires further investigation. This study focused on the possible implications of different cropping seasons and different nitrogen levels on selected agronomic traits in mustard. In this experiment, five different doses of nitrogen and two sowing periods were used to assess for their combined effects on the growth parameters, seed yield and agronomic characteristics of mustard in the semi-arid climatic conditions of Takestan. The results revealed that cultivation seasons and nitrogen rates had a significant effect on plant height, biomass yield, number of siliques per plant, seed oil content and seed yield.

In the present era, the global need for food is increasing rapidly; nanomaterials are a useful tool for improving crop production and yield. The application of nanomaterials can improve plant growth parameters. Biotic stress is induced by many microbes in crops and causes disease and high yield loss. Every year, approximately 20–40% of crop yield is lost due to plant diseases caused by various pests and pathogens. Current plant disease or biotic stress management mainly relies on toxic fungicides and pesticides that are potentially harmful to the environment. Nanotechnology emerged as an alternative for the sustainable and eco-friendly management of biotic stress induced by pests and pathogens on crops. In this review article, we assess the role and impact of different nanoparticles in plant disease management, and this review explores the direction in which nanoparticles can be utilized for improving plant growth and crop yield.

It is not enough simply to identify the limiting factors to agricultural production, supply the appropriate inputs and then expect to be able to meet food demands. It is essential also to protect the environment in which food is grown, especially in areas of fragile ecosystems and harsh climatic conditions, in order to ensure both increased production and stability of the production base. In the Nigerian savanna belt, traditional and mechanized large-scale farming systems are both practised, and they combine with unfavourable climatic conditions to exert a strong negative impact on the environment. Here, these interactions are examined and the case is made for incorporating fundamental ecological principles and concepts of sustainability into farming systems, in Nigeria and elsewhere.

In view of the significant increase in grain production in Russia, a methodological approach is proposed to analyze the significance of regional factors of grain crop yield growth in the country in recent years, especially against the background of the lack of expansion of acreage under grain crops. Based on the results of the calculations, the effectiveness of the influence of climatic, financial, infrastructural and production factors on the growth of grain yield was described. It is concluded that various factors had different effects on the growth of grain crop yields in regions with high-, medium - and low-intensity grain production complex. The role of reducing the influence of financial factors on the growth of grain yields and a sharp increase in the role of agro-climatic conditions is noted. The revealed trend of increasing depreciation of fixed assets of agriculture as a whole is particularly emphasized, with a slight increase in the volume of their renewal and modernization in the leading regions in terms of grain crop yield growth. Without taking appropriate measures to reduce the depreciation of fixed assets in the near future, this will result in a sharp decline in the achieved volumes of grain production in the country.

Although organic farming is an important topic for society, at the European level there have been few achievements so far. Despite its constant increase, the demand for organic food in Europe is outweighing the development of this sector. As such, we aim to assess the interaction between conventional and organic agriculture, as well as their impact on the value of agricultural production at the European level. The main objective of this article is the assessment of the impact of organic farming, as compared with conventional agriculture, on sustainable development of European countries. Therefore, we used panel models based on data collected from the Eurostat database. We found that an increase of 1% of the organic farming areas will generate a contraction in agricultural production of 0.278%, whereas a 1% increase in the production of fertilizers would generate an increase of 0.260% in agriculture production. Moreover, an increase of 1% in the production of plant protection substances and in gross capital formation would generate increases of 0.1190% and 0.0933%, respectively, in agriculture production. The obtained results depend mainly on the characteristics of work on land, as some agricultural engineering methods (crop rotation, pest control, use of fertilizers etc.) influence productivity and production.

The expected increase in population and the pressure posed by climate change on agricultural production require the assessment of future yield levels and the evaluation of the most suitable management options to minimize climate risk and promote sustainable agricultural production. Crop simulation models are widely applied tools to predict crop development and production under different management practices and environmental conditions. The aim of this study was to parameterize CSM-CERES-Wheat and CSM-CERES-Maize models, implemented in the Decision Support System for Agrotechnology Transfer (DSSAT) software, to predict phenology and grain yield of durum wheat, common wheat, and maize in different Italian environments. A 10-year (2001–2010) dataset was used to optimize the genetic parameters for selected varieties of each species and to evaluate the models considering several statistical indexes. The generalized likelihood uncertainty estimation method, and trial and error approach were used to optimize the cultivar-specific parameters of these models. Results show good model performances in reproducing crop phenology and yield for the analyzed crops, especially with the parameters optimized with the trial and error procedure. Highly significant (p ≤ 0.001) correlations between observed and simulated data were found for both anthesis and yield in model calibration and evaluation (p ≤ 0.01 for grain yield of maize in model evaluation). Root mean square error (RMSE) values range from six to nine days for anthesis and from 1.1 to 1.7 t ha-1 for crop yield and index of agreement (d-index) from 0.96 to 0.98 for anthesis and from 0.8 to 0.87 for crop yield. The set of genetic parameters obtained for durum wheat, common wheat, and maize may be applied in further analyses at field, regional, and national scales to guide operational (farmers), strategic, and tactical (policy makers) decisions.
