to investigate the effect of dose and applying time of paraquat on soybean weed control, especially wild melon, factorial experiment conducted as a randomized complete block design with four replications in 2009 in dashte naz co. sari-iran. the treatments included different doses of paraquat (0, 1, 1.5, 2 and 2.5 liters per hectare of commercial material) and different growing stages of wild me...

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...

BACKGROUND AND AIMS Light quantity and quality affect internode lengths in cucumber (Cucumis sativus), whereby leaf area and the optical properties of the leaves mainly control light quality within a cucumber plant community. This modelling study aimed at providing a simple, non-destructive method to predict final internode lengths (FILs) using light quantity and leaf area data. METHODS Sever...

ABSTRACT- Field experiments were conducted to determine the relationship between plant leaf area as the dependent variable with leaves number, leaf dry weight, and total vegetative components dry weight and plant height as the independent variables. Treatments were two tillage systems (conventional and no-tillage) as main plots, and seven sowing dates (11 May, 18 May, 25 May, 1...

in order to investigate genetic correlation and path analysis between grain yield and yield components, fifteen early maturing hybrids of grain corn (zea. mays) using a randomized complete block design with 4 replications were evaluated in khoramabad agricultural research center, iran. the data were collected and analyzed for ear emergence date, anthesis date, maturity date, plant height, ear h...

in order to study the effect of ca, k, and mn foliar spray on vegetative traits of safflower (padideh cultivar) under salt stress, a factorial experiment was conducted based on randomized complete blocks design with three replications in vali-asr university greenhouse. factors included salinity with four levels representing 0, 500, 1000, and 1500 mg nacl kg -1, and foliar spray with four level ...

seven maize inbred lines were crossed in a complete diallel cross design at the seed and plant improvement institute, karaj, iran, during the 2006 growing season. the parents and 42 f1 hybrids were grown in the research field of islamic azad university of firoozabad, firoozabad, iran, using a randomized complete block design (rcbd) with three replications, during the 2007 growing season. the ha...
