Chemical Weed Control in Paddy Fields Inoculated with Azospirillum lipoferum
Provedor de dados: 87
Autores: SEDDIGUI KIASARI,A.; AMINPANAH,H.; SHARIFI,P.
ABSTRACT: Herbicides, as a major part of weed control strategy in paddy fields, have different impact on growth and activity of soil-beneficial bacteria such as Azospirillum species. A field experiment was conducted at Sefid Rood Livestock and Agricultural Company, northern Iran, to investigate the possibility of chemical weed control in paddy fields inoculated with Azospirillum lipoferum. The experiment was designed in a factorial arrangement based on a randomized complete block with three replicates. The factors were Azospirillum application (inoculation with or without Azospirillum lipoferum) and weed management regime (butachlor application with supplementary hand-weeding, bensulfuron methyl application with supplementary hand-weeding, combination of...

Prospects for adopting system of rice intensification in Sri Lanka: A socioeconomic assessment
Provedor de dados: 31
Autores: Namara,   Regassa E.; Weligamage,   Parakrama; Barker,   Randolph.
Today, there is an increasing worldwide interest in assessing the potential for maintaining or increasing rice yields by reducing or eliminating the use of chemicals and by decreasing irrigation requirements. The System of Rice  Intensification (SRI) first developed in Madagascar and now being tested in many countries, is an example of such an approach. The system is based largely on organic farming principles and additional requirements for spacing and the transplanting of seedlings.

Estimation of infiltration rate of a paddy growing area in a micro watershed of Sikkim, India
Provedor de dados: 111
Autores: Patle, G T.
This study aimed to estimate the constant infiltration rates from paddy growing area of a micro watershed located in the hilly state of Sikkim, India. Double ring infiltometer test was used for the field measurement of infiltration rates. The observed infiltration rates were compared with predicted values obtained by Horton, Philip, Kostiokov and Green-Ampt infiltration models. The suitability analysis of models was checked through statistical tools namely coefficient of determination and standard error and the best model was identified for the paddy fields of hill topography. The soil samples were collected for the estimation of soil moisture content, bulk density and soil texture analysis. Soil texture was sandy loam to loamy sand within the micro...
