introduction integrated weed management is based on combination of several management methods, while reducing the rate of the use of herbicides, will result in efficient management and sustainable weed control. ability of crop tolerance and prevent weed growth are two important traits in weed competition. an appropriate and suitable cultivar, has high yield potential in the presence of weed and...

To determine how intra-row spacing and potassium levels affected sweet corn (Zea mays L. var. Saccharata), a field experiment was conducted in Junagadh (Gujarat) during the Rabi season of 2016–17. Four (5, 10, 15 20 cm) four (0, 20, 40, 60 kg K2O/ha) were combined into sixteen different treatment combinations. Three replications factorial randomized block design used to set up experiment. Based...

A model to predict the distribution of harvest dates in an Easter lily crop was validated using data from several locations. Plants were individually harvested (i.e. removed from the greenhouse for shipping) when flowers on a plant reached a minimum flower bud length. A computer decision-support system called LilyDate was developed to allow the model to be used to optimize greenhouse temperatur...

Thyme (Thymus vulgaris L.) is an important medicinal plant with highly valuable essential oils. In this study, effects of different fertilizer treatments and cuts on Thymus vulgaris L. was evaluated in 2008-2009. The research was conducted at Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The Experimental design was split plot in time in the form of a random...

Sustainable production of timber from commercial species across felling cycles is a core challenge for tropical silviculture. In this study, we analysed how the intensity and type (harvesting and thinning) of silvicultural interventions affect: (a) recruitment of small stems (5 cm 6 DBH < 15 cm), (b) increment of future crop trees (15 cm 6 DBH < 50 cm) and (c) recovery of harvestable growing st...
