Nitrogen is essential for both vegetative and generative stages of plant growth. Nitrogen efficiency is related to plant growth, production cost, and fertilizer residue. Azolla has the ability to increase nitrogen fixation from the atmosphere. Thus, Azolla cultivation in paddy field is one strategy for improving nitrogen fertilizer efficiency and increasing plant vegetative and generative growt...

wheat flour is known as the best nutrients supplier for human. in this research, the effects of combined application of nitrogen fertilizer, farmyard manure (fym), sewage sludge and municipal waste compost on nutrients concentrations of wheat flour (triticum aestivum cv. alvand) were studied in a randomized complete blocks design with 15 treatments and three replicates in agricultural research ...

Although cool-season grasses increase DM yield at high N rates, N recovery (kg plant N kg 1 N applied) Nitrogen removal by cool-season grasses may aid in capturing exgenerally declines as N rate increases. Ramage et al. cess N from animal confinement operations or phytoremediation. (1958) reported fertilizer N recovery of 0.59 and 0.59 kg Limited information exists on the N dynamics of these gr...

Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manur...

INTRODUCTION Desmopressin (DDAVP) testing (DT) in patients (pts) with haemophilia A (HA) and carriers (CHA) is up to now not standardized. This prompted us to evaluate results of DT carried out between 1996 and 2011 in centres of the Competence Network Haemorrhagic Diatheses East. PATIENTS AND METHOD An increase of the factor VIII activity (FVIII) above 50% or at least the two fold of initial...

Two cultural treatr7zents were applied in an overstocked loblolly pirze (Pinus taeda L.) plantation (2,900 trees/ha after eight growing seasorzs): precom~nercial tlzinning (Yes or No) to 747 tt-ees/lza after the eighth growing season and broadcast fertilizatiorz (Yes or No) with diamrrzonium phosphate (150 kg/ha of P and 135 kg/ha of N) early in the ninth growing season. Total height and diamet...

The effect of aldicarb and fenamiphos on Tylenchulus semipenetrans population densities and on orange yield was investigated during a 3-year (1986-88) field trial in Italy. Rates were 10 and 20 kg a.i./ha as an early spring single application, 5 kg a.i./ha in spring and 5 kg after flowering, and 5 kg a.i. in spring followed by 2.5 kg/ha after flowering and 2.5 kg/ha in early autumn. Rates and t...

A field experiment was conducted during Zaid 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil experimental plot sandy loam in texture, nearly neutral reaction (pH 7.1), low organic carbon (0.36%), available N (171.48 kg/ha), P (15.2 kg/ha) and K (232.5 kg/ha). laid out Randomized Block Design with nine treatments each replicated thrice on the basis one year ...

A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). To study treatments consisting three levels Nitrogen such as, 80, 100 and 120 kg/ha with spacing as 75 x 10 cm2, 60 20 cm2 45 30 cm2. The soil experimental plot sandy loam in texture, nearly neutral reaction (pH 7.1), low organic carbon (0.28%), available N (225 kg/ha), P ...

The article shows for the first time results of studies on aftereffect 4 years a single use dairy industry waste - cake as fertilizer crops in crop rotation link: potatoes spring wheat barley productivity and product quality. In 2017, experimental plot after harvesting remains perennial grasses was mechanically processed with motor cultivator divided into plots 10 m2 following options: 1. Contr...
