Nearly one quarter of New Zealand’s unique vascular plant flora is threatened, and weed invasion is implicated in the decline of more than half of these threatened species.

This study experimentally tested the hypothesis that competition with invasive weeds threatens the ...

Abstract The authors have designed a seed pelleter and combined precision sowing rig, which are the backbone of technology pre-sowing treatment sowing. method is based on operation continuous pelleter, where protective nutritious coating formed around seeds while they move along spiral trajectory. next component rig that performs several technological operations in one pass: laying drip tape fo...

in order to study the effects of different sowing dates on yield potential of cumin ecotypes and to appoint the best sowing dates of cumin at kerman, the present experiment was performed base on rcbd with split plot arrangement and 3 replications during growing season of 2011-2012. different sowing dates (25th december, 9th january, 24th january, 8th february and 23th february) as main plot, an...

the dragon's head(lallemantia iberica f. & c. m.) can be introduced as a new oilseed crop to cold rainfed areas because of its unique characteristics. the field trial was carried in a split-plot factorial in a randomized complete block design (rcbd) with three replications in dryland agricultural research institute (dari) in 2010-11. the treatments included three landraces of dragon’s head...
