The antiaggregation pheromone verbenone was operationally tested for 5 yr to deter mass attack by the mountain pine beetle on lodgepole pine in campgrounds and administrative areas surrounding RedÞsh and Little RedÞsh Lakes at the Sawtooth National Recreation Area in central Idaho. Each year, Þve-gram verbenone pouches were evenly distributed ( 10 m apart) within seven of 14 0.2-ha plots. Durin...

This research was conducted to determine the effects of different row spacings and sowing rates on hay quality characteristics under Tokat-Kazova ecological conditions during years 2014-2016. In study, cultivars alfalfa Bilensoy-80 sown at four (15, 30, 45 60 cm) six (5, 10, 15, 20, 25 30 kg ha-1) The experimental design completely randomized in split plots with replications. Main were sub-plot...

Doctor's dissertation. ISSN 1401-6230, ISBN 91-576-6304-1. Global warming is predicted to affect the carbon balance of forests. A change in the carbon balance would give a positive or negative feedback to the greenh...

The objectives of this study were to examine the effects of stand development and soil nutrient supply on processes affecting the productivity of loblolly pine (Pinus taeda L.) over a period approximately equal to a pulpwood rotation (18 years). The experiment consisted of a 2 x 2 factorial combination of complete and sustained weed control and annual fertilization treatments (C: control treatm...

terminal heat stress in mediterranean climates like ahwaz is reduced wheat yield. in order to study effect of terminal heat stress on yield and yield components of 20 spring bread wheat cultivars, an experiment was conducted in ramin university of agricultural and natural resources, ahwaz in 2007-2008. the experimental design was stripe block design in randomized complete block design with thre...

A field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during Aman season of 2011 to evaluate the effects of manures and fertilizers for maximizing the yield of BRRI dhan49. The experiment had six treatments, laid out in a randomized complete block design (RCBD) with four replications. The treatments were T0 = Control, T1 = ...

Sowing date and density are two important factors in produce of coriander. A field experiment was conducted with treatments: sowing time (5 May, 20 May, 4 June and 19 June 2009) and plant density (10, 30, 50 and 70 plants m). The experimental plots were laid out in a factorial according to a RCBD with three replications. Results showed that the effect of sowing dates and densities were signific...

Pyraclostrobin 25%EC at., 50, 75 and 100ga.i/ha, was evaluated for two seasons against early blight of tomato cultivar NS2535. The efficacy of pyraclostrobin was compared with commonly used chemicals viz., captan, mancozeb and an untreated control. Phytotoxicity effect of pyraclostrobin was evaluated using a single spray, at concentrations of 100, 200 and 400gm a.i/ha Pyraclostrobin at all conc...
