A field experiment was conducted for three consecutive years to study the effect of various combinations of nitrogenous fertilizer (in the form of urea), vermicompost and FYM on yield and soil-available nutrients in sapota. Largest number of fruits (4820 tree-1) and maximum fruit yield (31 tons ha-1) were recorded with 10kg vermicompost + 350:50:450g NPK tree-1, and was on par with application of 40kg FYM + 350:50:450g NPK tree-1. The net profit and yield trend over the years showed that application of 10kg vermicompost + 350:50:450g NPK tree-1 was more suitable for meeting nutrient requirement for enhanced yield in sapota. Application of organics (irrespective of source) showed positive, significant effect on organic matter content of the soil after three years. Highest build-up of organic matter in the soil was recorded with 10kg vermicompost alone (T10), which was at par with 40kg FYM alone (T5). Moreover, there was a clear trend of increasing total soil nitrogen content in plots supplied with increased levels of inorganic nitrogen with organic manures, and, this was subsequently reflected in potentially mineralized nitrogen, suggesting an improved labile pool of plant-available nitrogen. Therefore, there is an obvious need to include organic manures along with the inorganic nitrogenous fertilizer for optimizing the use-efficiency of soil and applied N to achieve sustainable yields in sapota for profit.Keywords

Potassium is often considered as the quality element for crop production. Grapevine is one of the most potassium-friendly plants that has a better ability to utilize soil potassium. Grape berries are a strong sink for potassium, particularly during ripening. To ascertain the influence of the combined application of different sources and methods of potassium application on the quality of grape cv. Sharad Seedless, an experiment was conducted at Indian Institute of Horticultural Research, Bengaluru during two consecutive years, viz. 2016–17 and 2017–18 with three different sources of potassium fertilizers (SOP, KNO3 and 19 : 19 : 19), and two methods of application (soil application and fertigation). Pooled analysis revealed that among the treatments, grapevines treated with sulphate of potash as 60% through fertigation and 40% through soil registered the highest total soluble solids (22.16° ºBrix), Brix : acid (36.38), total sugars (19.66%) and least titratable acidity (0.61%) in berries. With regards to biochemical constituents like total phenols, total flavonoids and anthocyanins, significantly highest value was observed in vines treated with 100% SOP through fertigation.Keywords
