9:30–10:10 Organic alternatives for cranberry fruit rot control/ Use of prophyte for Phytophthora root rot of cranberry/ Use of varying irrigation rates for cranberry cultivation (Bogs 11-16) A trial was planted to test the practical potential of several alternative establishment methods, particularly when plant material is limiting. The following aspects were considered: 1) quantity of plant m...

In terms of tillering potential, the aboveground portions of rice are significantly influenced by the nitrogen level (NL) and transplant density (TD). To obtain a suitable combination of NL and TD, five NLs (0, 90, 180, 270 and 360 kg ha-1) and two TDs [high density (HD), 32.5×104 hills ha-1; low density (LD), 25.5×104 hills ha-1] were used in the rice experiments during 2012 to 2014, in Jiangs...

Tropical forests continue to be deforested because forest owners believe they can earn more income through land uses involving forest conversion. A case study in a Mexican rainforest revealed that enrichment planting with the native tree species Pouteria sapota (‘mamey’) is a management approach that can increase the commercial value of the forest enough to compete with these destructive land u...

In intercropping distance research, traditional field experiments are time-consuming and tedious, and cannot be applied to quantitative interspecific distance quickly. Therefore it has become a big concern for researchers in this field to further reduce manual operation, and more automatically and quickly get the optimal planting distance. In this paper, an optimization algorithm was applied to...

The light deficiency in the canopy is not the main factor limiting maize (Zea mays L.) production but the lower radiation use efficiency (RUE). Conservation tillage planting patterns were used to construct a sustainable agricultural system for soil protection and higher RUE. On these bases, we tried to create more uniform light distribution in crop canopy for increasing radiation use efficiency...

We examined the influences of selected environmental variables on stomatal behavior and regulation of transpiration in 26-month-old Acacia koa Gray (koa) stands planted at spacings of 1 x 1 m or 2.5 x 2.5 m and grown without irrigation. Field measurements were made during recovery from an extended 60-day dry period with only 38 mm of precipitation. Biomass and leaf area were also measured at 3-...

The limitations on spatial resolution and on the availability and measurement accuracy of remote sensing images are the primary problems in the estimation of the large-scale planting area for maize. The integration of midand low-resolution images is the one of primary methods used for the estimation of large-scale crop planting areas using remote sensing. The use of a single-temporal thematic m...

Field experiment was conducted at KPK Agricultural University, Peshawar, Pakistan to find out the effect of planting methods on the yield and yield components of maize varieties. Analysis of the data revealed that planting methods had a significant effect on days to tasseling, days to silking, plant height, number of plants ha at harvest, thousand grain weight, grain yield, biological yield, fr...
