The research interest on plant biostimulant applications in vegetable crop production is gradually increasing and several reports highlight the beneficial effects that such products may have not only on crop performance but also on the quality of the final product. Moreover, numerous products with biostimulatory activity are being developed which need further evaluation under variable growing conditions and different crops. Plant hydrolysates which contain amino acids and peptides have been acclaimed with several positive effects on crop performance of diverse horticultural crops, while macro-algae are also considered effective biostimulants on plants grown under stress conditions. A recent study evaluated the use of protein hydrolysates and brown macro-algae (Ascophyllum nodosum and Ecklonia maxima) as innovative and cost effective approaches for sustainable vegetable production. The present editorial provides an overview of the main findings of that study, while discussing the practical applications that biostimulants may have in the greenhouse production of vegetable crops, aiming to increase the yield and the quality of the final produce and improve crop tolerance to abiotic stressors.

A well planned intercropping system can efficiently serve as alternative to input such as fertilizer, herbicides, pesticides and pathogenicides. The interaction between the intercrop species, soil and environmental factors have positive effects on crop nutrition and photosynthesis and these have improved the nutrient content of the soil and different intercrop components. The high percentage ability of the intercrop species to suppress weeds especially when legume crops are involved in the plan, improves the physicochemical properties of the soil, contributes to the health of the intercrop species as the intercrop promotes the synthesis of allelopathic compounds and phenolic compounds such as anthocyanins and flavonoids which may serve as a deterrent to diseases and pests and improve the quality of the intercrop plants. Due to its inherent biological, biochemical and physiochemical properties intercropping system may be used to promote sustainable crop production and for safe management and cost-effective agricultural activities.

Vegetable cultivation is a promising economic activity, and vegetable consumption is important for human health due to the high nutritional content of vegetables. Vegetables are rich in vitamins, minerals, dietary fiber, and several phytochemical compounds. However, the production of vegetables is insufficient to meet the demand of the ever-increasing population. Plant-growth-promoting rhizobacteria (PGPR) facilitate the growth and production of vegetable crops by acquiring nutrients, producing phytohormones, and protecting them from various detrimental effects. In this review, we highlight well-developed and cutting-edge findings focusing on the role of a PGPR-based bioinoculant formulation in enhancing vegetable crop production. We also discuss the role of PGPR in promoting vegetable crop growth and resisting the adverse effects arising from various abiotic (drought, salinity, heat, heavy metals) and biotic (fungi, bacteria, nematodes, and insect pests) stresses.

This chapter is concerned with a set of optimization problems associated to crop rotation scheduling in the context of vegetable crop production according to some ecological criteria: no crop of the same botanic family is planted in sequence, green manure and fallow periods must be present in any schedule. A core mathematical model called the crop rotation scheduling model is proposed to represent these ecological criteria together with specific technical constraints associated to the growing of vegetable crops. Three optimization problems based on crop rotation schedules are written in detail in this chapter. For each problem, the authors present a general modeling framework and a solution methodology based on a technique known as column generation, which iteratively builds crop rotation plans for a number of plots. Some extensions are also presented, with the aim of incorporating additional characteristics found in production field conditions. This chapter ends with a brief discussion on a set of computational experiments and some suggestions for future research.

Abstract Vegetable production in Jamaica, and throughout the world, faces many diseases that affect the yield and the quality of the fresh harvest produce. However, some diseases are more predominant than others. The most observed diseases of vegetables are anthracnose, leaf spot, club root, downy mildew, gray mold, mosaic and geminiviruses, early blight, septoria leaf spot and leaf rusts. Nevertheless, other diseases can also be found seriously affecting the grown vegetable. Greenhouse cropping systems are also affected by similar and other diseases such as septoria leaf spot, early blight, anthracnose, fusarium wilt, verticillium wilt, late blight, bacterial spot, bacterial speck, bacterial canker, gray mold, leaf mold, powdery mildew and elephant's foot disease. Although not specific to the country, other diseases are also found more frequently than others, and the frequency varies with the region and the cropping system (indoor or outdoor).

AbstractCrop production in most developing countries is faced with a dearth of resources for optimum production of which fertilizer is one. The use of human urine as well as its mixture with compost are potential solutions to this problem. Thus, this report investigated the influence of human urine and its combination with compost on yield and soil quality of land under green amaranths (Amaranthus caudatus). This study involved a field experiment to determine the response of green amaranths to the application of 100% urine, 2/3 urine N + 1/3 compost N, 100% compost N, NPK (15:15:15) at the rate of 100 kg N ha−1 and control with no fertilizer treatment using farmers’ participatory approach. The vegetables produced from the experimental treatments were analyzed in the laboratory for pathogenic microbial risk as well as effects of the fertilizer on nutrient status of the experimental soils (before and after planting). Perception of farmers and consumers in the study area regarding use of urine as fertilizer for vegetable production was investigated with the aid of a structured questionnaire. The result of this investigation revealed that 100% urine resulted in 58.17 t ha−1 total plant yield, while NPK 15:15:15 gave 34.34 t ha−1 total plant yield in the two plantings. Microbial analysis of edible portion of vegetable from plot fertilized with urine did not reveal any significantly different pathological contamination compared to other fertilizer treatments used in this investigation. Urine treatment improved soil nutrient exchangeable cations and acidity. The perception study revealed that respondents perceived urine to be a good agricultural input that could be used as a fertilizer in vegetable crop production and there was no strong cultural norm that would prevent them using it for crop production. Vegetable consumers would also buy vegetable crops grown with urine if they are well informed about its safety for crop production. Since the use of urine as fertilizer for crop production improved amaranth's yield and did not show any negative implication on soil environment, human urine seems to have good potential both in crop yield and acceptability by farmers and consumers.

Method Of Evaluation

Questions of quality of the sowed seeds in agriculture have paramount value. Use of highquality uniform seeds is the key to successful production of crop production. Vegetable seeds, in particular, leaf vegetables, are most vulnerable in this plan in view of their shallow amount, the long period of fructing time and some other factors. The modern tool methods of evaluation test allow to glance in internal structure of seeds and to scoop more information. The most suitable for these purposes is us the developed method of microfocal X-ray of vegetable seeds. In this work seeds of different types of green and spicy and flavoring vegetable crops are analysed: melissa, marjoram, asparagus, spinach and garden cress. The analysis was carried out both by a method of r of seeds, and by a standard technique. The most typical defects and shortcomings of internal structure of seeds influencing their economic and biological indicators are identified. Comparison of methods is carried out. It is shown that X-ray analysis of quality of seeds, in particular, viability, by visualization of images efficient and rather precise. The small error of a method is compensated with its bigger informational content: that is, the analysis is carried out not by the principle of viable and not viable seeds, there is their division as on viability (full, low quality), and on defects and shortcomings (outstanding, ugly, the defective, injured, etc.). At the same time seeds as a result of the analysis aren't utilized and remain for further work. The method differs in speed and ease of execution. The prospects of development of a method are specified. It is the integrated automatic analysis of quality of seeds. The algorithm of automatic computer X-ray analysis of quality of vegetable seeds is so far developed, the first version of the program is approved.
