poplar trees are becoming extremely important as fast growing species due to the increasing need for wood and decreasing productivity of some lands in iran. the present study aimed to find the effect of canopy of poplar clones as one of the most important effective factors on soil properties compared to the distances inter-row trees. five poplar clones and species included: populus euramericana...

A field study was conducted during kharif, 2021 at College Farm, of Agriculture, Rajendranagar, PJTSAU to evaluate the performance rice varieties under different systems cultivation for Southern Telangana Zone. The treatments consisted three i.e., transplanted with spacing 15 cm x 10 cm, wet direct seeded (Drum seeding) a 30 6-8 and dry 5 row in main plots four RNR 11718, JGL 11118, 24423 15048...

in order to evaluate the effects of intercropping of maize- peanut, weeding and their planting design on weed population dynamics, an experiment was conducted as a factorial experiment in the form of rcbd with three replications at the research farm of agriculture center of zabol university (iran) in 2012. the treatments including sowing system in four levels as first factor  (sole maize, sole ...

At present a small number of full-scale marine current energy converters are undergoing sea trials to demonstrate commercial viability of the technology. In order to provide meaningful quantities of electrical power to the grid, the next phase in the development of the technology will be the installation and operation of farms or arrays composed of multiple devices. As most tidal current sites ...

management practices can affect the yield, maturity, and fiber quality of cotton. one practice used to increase yield has been to adjust the spacing between cotton rows. typically cotton is planted in row spaced 70-100 cm apart. ultra narrow row cotton production has been proposed as an economical means to increase yields and reduce production costs. a field study was conducted to assess the ef...

to yield reductions (Higley, 1992; Hunt et al., 1994; Haile et al., 1998). Hunt et al. (1994) concluded that removal Soybean [Glycine max (L.) Merr.] producers in many regions of of leaf area delayed the time to achieve a critical leaf the USA are confronted with significant yield losses because of crop damage from white-tailed deer (Odocoileus virginianus). Our objecarea index (LAI) of 3.5, li...

A field experiment was carried out during the summer season to study effect of microclimate modification on growth and yield paddy straw mushroom under outdoor cultivation as maize intercrop. Randomised Complete Block Design (RCBD) with eight treatments comprising combination spacing (60 x 25 cm, 45 paired row 45/75 30/60 cm) mulching (with or without application), in three replications used fo...

in order to study the effects of supplemental irrigation and planting arrangement on yield, yield components and water use efficiency (wue) of kabbuli chickpea (cv. arman), an experiment was carried out at the agricultural research station of gonbad for two years, iran. the experiment was a split-plot factorial arranged in a randomized complete block design with three replications. the main plo...

The characteristics of effectiveness and heat transfer for a row jets impinging on corrugated surface were experimentally investigated. Reynolds number, Re which was calculated based the exit velocity hydraulic diameter nozzle, 20000 jet-to-target spacing, L, varied from 2 to 10 times jet diameter, d. spacing between adjacent jets, Sx, kept constant at 4d. actual angle impingement distance diff...

Yield per unit area increased rapidly to a maximum as the number of stools increased, and either remained relatively constant or declined slightly with higher stool densities, depending upon the particular component of yield. The results imply that under favourable growing conditions, maximum yield per unit area can be achieved with relatively low stool populations. There is considerable potent...
