A field experiment was carried out at the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Rabi 2021-2022 with a view to determine performance different varieties spinach beet (Beta vulgaris var. bengalensis) for its growth, yield under Prayagraj climate work economics various treatments. U...

In this study, we evaluated the effects of municipal solid waste compost supplemented with inorganic N on physicochemical properties soil, plant growth, nitrate concentration, and antioxidant activity in spinach. Experiments were carried out neutral acidic soils that low organic matter. A fertilized soil was used as a control, while four treatments—two rates 35 70 t ha−1, or not (92 kg ha−1 Ca ...

The residual effects of biochar doses on Entisols after five years application have not received attention. However, there is an assumption that the positive can last longer in soil. Therefore, field experiments were carried out polybags to assess impact applying fifth year and addition urea fertilizer growth red spinach (Amaranthus tricolor) Entisol. growing media used this study was a medium ...

Intensive cultivation of vegetables and imbalanced fertilization depleted the soil nutrients caused low yield with poor quality crops. A novel microbial enriched biochar fertilizer combination could alleviate nutrient stress. Therefore, a field experiment was conducted 14 treatments [4 levels (5, 7.5,10, 15 t ha-1), 3 doses fertilizers (50, 75,100% recommended) along without absolute control] i...

A Planck law relationship between absorption and emission spectra is used to compute the fluorescence spectra of some photosynthetic systems from their absorption spectra. Calculated luminescence spectra of purple bacteria agree well but not perfectly with published experimental spectra. Application of the Planck law relation to published activation spectra for Systems I and II of spinach chlor...

Inhibition of net photosynthesis (Pn) by moderate heat stress has been attributed to an inability of Rubisco activase to maintain Rubisco in an active form. To examine this proposal, the temperature response of Pn, Rubisco activation, chlorophyll fluorescence, and the activities of Rubisco and Rubisco activase were examined in species from contrasting environments. The temperature optimum of Ru...

BACKGROUND Insulin resistance, which is associated with an increased risk of cardiovascular morbidity and mortality, has become a leading nutrition problem. Inorganic nitrate enriched in spinach has been demonstrated to reverse the pathological features of insulin resistance and endothelial dysfunction. However, the effects of a direct intake of nitrate-enriched spinach on insulin resistance an...

The content of individual chlorophyll and carotenoid pigments is determined in three spinach varieties (Lorelei, Springfield, and Ballet) after processing. Raw spinach and spinach that is steam-blanched for 3, 9, or 15 min is stored frozen at -24 degrees C for 6 months. In addition, spinach is air-dried at 75 degrees C, packed in atmospheric air or nitrogen, and stored at ambient temperature fo...
