Effect of Nitrogen and Plant Spacing on Nutrients Uptake,Yield and Growth of Tuberose (Polianthes tuberosa L.)
Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed th...
متن کاملNitrogen–phosphorus–potassium Effects on Forms of Sulfur in Leaves and Fruits of Cucumber
The impact that nitrogen (N), phosphorus (P), and potassium (K) application rates on the sulfur (S) fractions in leaves and fruits of greenhouse-grown cucumbers plants (Cucumis sativus L. cv. Brunex) are presented. The treatments were as follows: N (N11⁄4 5 g NO3NH4=m, N21⁄4 10 g NO3NH4=m, N31⁄4 20 g NO3NH4=m , N41⁄4 40 g NO3NH4=m), two levels of P (P11⁄4 8 g H3PO4=m 2 and P21⁄4 16 g H3PO4=m), ...

متن کاملCanola Response to Nitrogen, Sulfur, Phosphorus, and Potassium Fertilization in Arkansas
Canola (Brassica rapa) is an oilseed crop that is related to broccoli (Brassica oleracea var Italica) and turnip (Brassica campestris var Rapifera). The name ‘canola’ actually stands for ‘Canadian oil, low acid’. Canola’s low erucic acid content differentiates it from rapeseed (Brassica napus) and is sometimes referred to as LEAR or ‘low erucic acid rapeseed.’ Canola seed contains about 40% oil...
متن کاملNitrogen, Sulfur, Potassium and Phosphorus Fertilization in Alfalfa When Are They Necessary?
Determining when applications of nitrogen (N), sulfur (S), potassium (K) and phosphorus (P) fertilizer are needed is important to maintain alfalfa yield and quality. The Western U.S. is diverse in terms of climate, soil types, irrigation water need and availability, historical nutrient use and alfalfa production systems. Therefore, few generalizations hold regarding the timing and location of N...
