Maize is the staple food of China, produced on 33.6% total arable land. In this context, an effective strategy to enhance maize yield essential meet demand without expanding cultivation areas. can be increased by two key measures: plant-row space optimization and nutrient management. However, in traditional practices, fertilizer utilization plants inefficient. We therefore performed a manipulat...
in order to evaluate the effect of row space and weed management on weed population, chickpea yield and yield components, a factorial experiment based on rcbd with three replications was conducted at field research of agriculture college of lorestan university in cropping season of 2006-2007. in this research experimental factors were chickpea row spaces with four levels (15, 20, 30 and 40 cm w...
Including cover crops in established crop rotations can enhance the delivery of ecosystem services from agricultural lands. Inclusion rainfed cropping systems northern Great Plains, however, is challenging due to short growing season, limited precipitation, and variable weather conditions. Cover interseeding row has been proposed as one approach address these challenges. A 3-yr study was conduc...
Effects of transplanted seedling density and species on sward structure of native warm-season grass (NWSG) stands were compared in a randomized complete block design. About 6-week-old NWSG (big bluestem (BB, Andropogon gerardii Vitman), eastern gamagrass (GG, Tripsacum dactyloides L.), indiangrass [IG, Sorghastrum nutans (L.) Nash] and switchgrass (SG, Panicum virgatum) seedlings were transplan...
Intra-row spacing is known to determine early productivity of super-high density olive orchards depending on growing conditions, cultivar growth characteristics, planting geometry and subsequent pruning management but few experiments have been carried out in this olive hedgerow orchard design. In 2008 an experiment of 4-m spaced hedgerows was established with 8 intra-row spacings (from 1.0 to 2...
Abstract Climate adaptation is an essential strategy for responding to climate change at local levels and required sustainable food production meet the growing demand. In this light, study analyzed effects of strategies on technical efficiency maize farmers in Northern Ghana. This involved a total 619 that were selected through multistage sampling procedure. A Cobb-Douglas stochastic frontier w...
in order to study the effect of planting pattern and herbicide application on corn (zea mays l.) grain yield and weeds control, an experiment was carried out in 2007 at varamin research station of plant protection research institute. the experimental design was a randomized complete block in a split plot arrangement with 4 replications. experimental factors consisted of planting patterns at 4 l...
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...
Stale seedbeds are used by organic growers to reduce weed populations prior to crop planting. Ryemulches, derived from mechanically killed (rolled and crimped) winter rye cover crops, can serve the same purpose for spring-planted organic crops. Both methods can also be employed by conventional growers who face looming problems with herbicide resistant weeds. The objective of this research was t...
