A study was conducted in the Shandong province in North China to investigate the effects of different planting patterns on water potential characteristics of soil-plant-atmosphere continuum (SPAC) and yield of summer maize. Three planting patterns were applied, i.e. bed planting (BE), furrow planting (FU) and flat planting (FL). The results showed that although soil moisture content in 0–20 cm ...

The use of water resources should be restricted until a suitable irrigation and planting system is developed in the North China Plain. This study was aimed to study the effects of planting pattern and irrigation on the farmland microclimate, and indentify possible ways to improve the yield of winter wheat. The field experiments in a randomized complete block design with four replicates were con...

Iran with a cultivation area of 45000 ha and production of 150 ton/year is the number one saffron producer in the world. Planting of large size corms will increase flowering, but production of corms (number and size) may be affected by irrigation method or frequency. In this research which is performed in the farm of College of Agriculture, Shiraz University, the effects of method and frequency...

water resources are limited in most parts of the country, including isfahan,where cotton is cultivated but it’s planting time coincides with the sensitive stage of cereal grain growth. therefore, developing and adopting techniques that could maximize use of the existing resources is needed. to study the effect of basin and furrow irrigation methods on yield and some yield components of cotton  ...

Agricultural investigations use computer models for simulation of crop growth and field water management. By using these models, the effects of plant growth parameters on crop yields are simulated, hence, the experimental costs are reduced. In this paper, the model of MSM (Maize Simulation Model) was calibrated and validated for the prediction of maize forage production at Agricultural College,...

J. Econ. Entomol. 72: 261-264 (1979) Potatoes grown under furrow irrigation sustained over 58 times greater infestation by Phthorimaea operCIIlella (Zeller) and 3 times more green tubers than potatoes grown under sprinkler irrigation even though foliage tuberworm populations, soil type, and soil moisture levels were similar. Water usage on a per ha basis was more efficient under sprinkler irrig...

The ridge and furrow farming system for rainfall concentration (RC) has gradually been popularized to improve the water availability for crops and to increase the water use efficiency (WUE), thereby stabilizing high yields. In the RC system, plastic-covered ridges are rainfall harvesting zones and furrows are planting zones. In this study, we optimized the mulching patterns for RC planting to m...
