ABSTRACT: Crop-weed competition and interactions are the focus of many researchers to make the weed management decision accurate and economical. Therefore, field studies were conducted in two consecutive years (2012-13 and 2013-14) at two different locations viz Peshawar (34.0167o N, 71.5833o E) and Chitral (35o50’46" N, 71o47’9" E) of Khyber Pakhtunkhwa (KPK) province, Pakistan. The aim of the studies was to determine the competitive ability of wild oat (Avena fatua L.) with wheat (Triticum aestivum L.) at two ecologically different locations and the possible effects on quantity and quality of wheat grains. In field studies, the experiment were laid out in randomized complete block design (additive design) with three replications in which the seed rate of...

ESTIMATING YIELD LOSSES AND ECONOMIC THRESHOLD LEVEL OF Parthenium hysterophorus IN FORAGE SORGHUM
Provedor de dados: 87
Autores: ASIF,M.; AYUB,M.; TANVEER,A.; AKHTAR,J.
ABSTRACT A field trial was conducted for two consecutive years to evaluate the effect of different parthenium densities (0, 2, 4, 6, 8, 10, 12, 14 and 16 plants m-2) on the yield and yield components of forage sorghum along with parthenium economic threshold level. The experiment was laid out during the summer in a randomized complete block design with four replications. Different parthenium densities reduced yield and yield components of forage sorghum, as the parthenium density increased significant decline in yield and yield components. The highest parthenium density (16 plants m-2) reduced plant height by 17.19% and 15.32%, stem diameter by 31.79% and 28.10%, leaf area per plant by 18.88% and 10.16%, leaf to stem ratio by 51.01% and 45.03% and fresh...

Shortage of good quality rice seeds is the main problem in rice production system in Thailand. One of the important factors affecting quality and quantity of rice seeds during storage is the damage caused by storage insects which resulted in 3.2 – 4.5% weight loss. For the effective control of these insects, understanding of type, shape, life cycle and types of damages must be concerned. Five sacks of sixty kilograms of RD6 rice seed stored in jute sack were placed in 5 positions in the rice silo during January 2014-January 2015. Each month, 1 kilogram per sack of rice seeds was sampled to investigate types, number of the insects and quality of rice seeds.  The results revealed that there were 5 types of insects found during storage; Angoumois grain moth,...
