Reduced Water

As climate change evokes changing precipitation patterns, the cultivation of vegetable crops in open fields might become more difficult in the future. Nowadays, many vegetable growers are already facing relatively long unprecedented precipitation-free periods. In many growing regions, irrigation is only available to a limited extent or not at all, and the cultivated plants will suffer from moderate water stress more often. Therefore, we examined the effects of moderately-reduced water supply on the chemical composition of pickling cucumber, cultivated in an open field and in a separate greenhouse trial. In the field trial, the reduced water supply treatment (RWS) provided 85–90% of the total water amount of the well-watered control treatment (CTR), applying a randomized block design with six replications comprising two consecutive weekly harvest periods. In fruits obtained by cultivation with reduced irrigation, levels of malic acid, calcium, and magnesium significantly increased, while those of phosphate, phosphorous, nitrogen, and iron decreased based on dry matter. Fresh matter-related results additionally revealed a decrease of myo-inositol and zinc, while sugars and total phenols remained unchanged. In the greenhouse experiment, the RWS obtained 60% of the irrigation amount of the CTR. Here, single cucumber compartments (exocarp, mesocarp, and endocarp) were examined. Chemical compositions changed in a similar, but more pronounced, manner as compared to the open field trial. The levels of individual, nutritionally relevant carotenoids in the peel of pickling cucumber, like lutein and β-carotene, were affected by RWS. Regarding the nutritional quality of fresh marketable cucumber fruits, malic acid, certain minerals and trace elements, as well as the carotenoids were shown to be sensitive to moderate water reduction.

Research Article

AbstractThe success of genetically modified crops (GMCs), claimed to hold solution to impending environmental problems, depends on land holdings, agroclimatic and geoclimatic conditions, food preferences and sociocultural factors. The direct and indirect impacts of these crops on human health, ecology and environment have not been evaluated on long-term basis. In India, with rich background of farming, GMCs remain a minor change. Introduction of first GMC, Bt Cotton (BC), showed varied response throughout the country. New GMCs like Bt Brinjal and GM Mustard approved for open-field trials in the country were marred under contentious debate and were never approved for commercial cultivation. The current research article aims to study the ecological implications of only GMC available for experimentation in India, BC. A three-phase study carried out as field survey, glass dome experiments and open-field trials compared the BC and conventional cotton (CC) plants with extensive experimentation of ecological parameters including vegetation diversity, insect diversity, plant morphology and infestation intensity. Results highlighted the better morphological characteristics of BC over CC, while infestation studies showed 40% survival rate of insect pest on BC for which it is genetically modified. High electrical conductivity and low organic matter content in the BC soil samples as compared to CC soil samples were indicative of impact of Bt toxins in soil but need further in-depth soil studies to reach scientifically valid results. The current research article substantiates the environmental concerns raised against GMCs especially BC in the country. Its objective is to trigger more research in this direction, so that the technology of GMCs is utilized for the benefit of humankind.
