Abstract Accurate estimation of tuber size distribution (TSD) parameters in discretely categorized potato ( Solanum tuberosum L ) yield samples is desirable for estimating modal sizes, which fundamental to prediction. In the current work, systematic digs were conducted on five commercial fields N = 119) compare Weibull, Gamma and Gaussian functions relative-likelihood-based goodness-of-fit obse...

High N fertilizer and irrigation amounts applied to potato (Solanum tuberosum L.) on coarse-textured soils often result in nitrate (NO3) leaching and low recovery of applied fertilizer N. This 3-yr study compared the effects of two rates (140 and 280 kg N ha(-1)) of a single polyolefin-coated urea (PCU) application versus split applications of urea on 'Russet Burbank' potato yield and on NO3 le...

qareh qeshlaq marble quarry as one of the valuable resources of ornamental stones in west azarbaijan province formed through thermal carbonate springs while its mineral deposit thickness is limited in comparison with surface extension. in the present research, geological and blocky modeling of the marble deposit was carried out in order to develop a production planning for this quarry, identify...

Abstract Brazilian potato production is based on cultivars originating from the USA and Europe; however, these were developed under different environmental conditions than those found in Brazil. The aim of this study was to evaluate adaptability stability 18 clones (MLG), by Universidade Federal de Lavras, four six environments state Minas Gerais, following traits evaluated: marketable tuber yi...

In order to investigate the effect of organic and inorganic nutrient sources on sweet potato tuber yield, we carried out a series of experiments at Hobu, Morobe Province, PNG. In the first experiment, plots were planted with Piper aduncum , Gliricidia sepium and Imperata cylindrica . After one year, these plants were slashed and sweet potato was planted. Sweet potato yield was lowest in plots w...

The aim of the study conducted in 2019-2021 was to determine effect biostimulants and growth regulators on yield size structure, as well chemical composition edible potato tubers. cultivar evaluated Vineta. Asahi SL, Kelpak Aminoplant, Tytanit, gibberellic acid (GA3) Moddus 250 EC were applied cultivation. application SL Tytanit increased total marketable tuber yield, average weight. Aminoplant...

Irrigation is required for profitable commercial potato (Solanum tuberosum L.) production. Excessive or deficit soil water availability during the growing season can have adverse effects on tuber yield, quality, and storability. A field study was conducted 2018 2019 storage seasons in Central Wisconsin, a region U.S. with high volume of production, to evaluate impacts different irrigation rates...

In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...

Traditionally, Corydalis tuber has been used for the control of pain including headache, stomach ache, and neuralgia. In the present study, modulation of the Corydalis tuber on glycine-activated ion current in the acutely dissociated periaqueductal gray (PAG) neurons was studied by a nystatin-perforated patch-clamp technique. High concentrations of Corydalis tuber elicited ion current, which wa...
