In order to finding cultivars with high yield and compatible with potato in the form of fall cultivation in jiroft area, an experiment in randomized complete block design with three replication, was done in Jiroft agricultural research center in 2013. In this experiment height plant, No. Stem, Tuber diameter, Tuber weight/plant, No. tuber and yield were examined. Effect Prevent Freezing Cropaid...

application of trichoderma species is a harmless method in controlling soil borne plant diseases thus reducing hazardous pesticide use and environmental pollution. some trichoderma isolates performing proper inhibitory effect against fusarium oxysporum f. sp. tuberosi under laboratory and green house conditions were screened against wilt disease of potato caused by this pathogen under field con...

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 and 50+200...

this study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in iran. to this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. the main factor included different levels of silicon (0, 10, 20, 30 mm.l-1) ...

in order to study the weed populations in wheat, under different crop rotations an experiment was carried out at agricultural research station of jolgeh rokh, iran. during growing season this project was done in five years, based on randomized complete bloch design with three replications, on crop rotations included: wheat monoculture for the whole period (wwwww), wheat- wheat- wheat- canola- w...

in order to investigate the possibility of planting grass pea and common vetch crops after harvesting wheat and to evaluate the effects of  green manure of these crops on yield of potato-wheat in croprotation cycle, this research was carried out using a randomized complete block design with four replications during 2006-2010 at khair-abad research station, zanjan, iran. the treatments were eith...

India is the second largest producer of potato in the world. The Indo-Gangeticplains (IGP) is the main potato growing region accounting for almost 85% of the1.8 Mha under the crop in India where it is grown as an irrigated crop during thewinter season. Since IGP is in sub-tropical plains, duration of the thermally suitablewindow is the main determinant limiting yields. Hence the impact of clima...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

MANEVA, S. and Zl. TRIFONOVA, 2015. Globodera rostochiensis population density effect on potato growth and yield. Regression models estimation. Bulg. J. Agric. Sci., 21: 815–821 Effect of initial population densities (Pi) of Bulgarian population of Globodera rostochiensis on the population dynamics and potato plants growth and yield was investigated in glasshouse and estimated using mathematica...

J. Econ. Entomol.91 (1): 7-20 (1998) ABSTRACT The relationship between Irish potato tuber yield, So/anum tuberosum L., and defoliation by the Colorado potato beetle, Leptinotarsa decem/ineata (Say), was investigated and the use of regression and mean separation analyses as a basis for developing economic injury levels were compared. The type of statistical analysis used to describe this relatio...
