In the 1990s numerous winter orographic cloud seeding experiments were conducted over Utah’s Wasatch Plateau. Several previously published case studies successfully documented the physical response in clouds and precipitation to ground-based seeding with silver iodide and liquid propane. A previously unpublished case study that shows additional evidence of positive seeding effects is presented ...

Four cloud-seeding cases over southern Idaho during the 2010/11 winter season have been simulated by the WeatherResearch and Forecasting (WRF)model using the coupled silver iodide (AgI) cloud-seeding scheme that was described in Part I. The seeding effects of both ground-based and airborne seeding as well as the impacts of model physics, seeding rates, location, timing, and cloud properties on ...

Edible-oil flax (Linum usitatissimum L.) can be an alternate oil-seed crop in Isfahan region. Seeding date is very important in obtaining higher grain yields and a successful flax production. The present study was conducted at the research farm, Isfahan University of Technology in the year 2000 to determine the effect of seeding date and genotype on yield, yield components and maturity of edibl...

In direct seeded rice, weeds are the major problems limiting crop productivity. Sesbania with rice (DSR) as well seeding rates of affects weed density by smothering effect and therefore, it can be a better management practice. Two year on farm trials were conducted at Kusma, Boarijore Block Bhaluka, Sundarpahadi block Godda from 2020 2021 to assess yields economics in DSR. The results revealed ...

The remobilization of water soluble carbohydrates (WSC) has an important role for grain yield. This study investigated the accumulation and remobilization of WSC in non-leaf organs (chaff, upper stem, and lower stem) and their contribution to grain yield, under different irrigation levels (rainfed, reduced irrigation, and full irrigation) and seeding rate treatments (450, 600 and 750 plants...
