to study the response of pinto-bean yield and yield components in intercropping with maize and naked-pumpkin under weed competition, two similar experiments were conducted in rasht and roudsar separately each in a randomized complete block design with 3 replications on factorial arrangements experiment in 2013. the treatments of first factor consisted of pinto bean (100 and 75%) sole cropping,...
In order to study the effects of weeding and plant density on forage yield of two sorghum cultivars, an experiment was conducted in 2011 at Bahonar University of Kerman Research field station. The experiment was designed as a randomized complete block with a factorial-split treatment arrangement and with three replications. Treatments were included four levels of weeding (whole season wedding, ...
To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
An experiment was conducted at the Research and Training Farm of Federal College Horticulture Gombe State (10020’N 10030’E) during 2021 rainy season in Sudan Savanah agro-ecological zone Nigeria. The aim research is to evaluate effect seedling age time application post-emergence herbicide on growth yield lowland rice (Faro 44). consisted two factors, namely:- ( 3, 4, 5-week-old seedlings) weed ...
The effect of some weed control treatments (Bifonex, Tribenuron-methyl, hand weeding and unweeded check), five wheat cultivars (Sakha 69, Sids 6, Sids 7, Sids 8 and Sids 9) and their interaction on the productivity of wheat plants and associated weeds were examined under the sandy soil conditions. The obtained data indicated that total dry weight/m2 recorded at 60 days from wheat sowing signifi...
Winter flooding of paddy rice production is characterized by fields during the winter fallow season. It has attracted attention in terms its ecological function, supporting biodiversity field ecosystems. Therefore, recent Japan been conducted organic farming. However, it not well documented how farming with affect productivity rice. We experiments to examine changes yield compared those convent...
