Pest Management Science, 1999
To evaluate the fate of pesticides in paddy fields, the pesticide paddy field model (PADDY) has been developed for predicting pesticide concentrations in paddy fields and the run-off amount of pesticides to the aquatic environment. This model focused particularly on granule formulation because these formulations have been used widely as herbicides on ...

Linguistics of the Tibeto-Burman Area, 2023
Abstract This brief note proposes a new Proto-Sino-Tibetan etymon for FIELD-DIKE, the dike between irrigated paddy fields, and provides an etymology relating Chinese and Lahu forms. It also discusses related etymologies with similar rhymes in Lahu and their reflexes in Burmese. There is also a postscript on the Written Burmese rhyme -añ.

Seasonal variations of carbon isotopic composition of methane from Indian paddy fields
Global Biogeochemical Cycles, 2008 Systematic measurements of methane (CH4) flux and δ13C of methane from two paddy fields, one each from southern and western India, were carried out. There is a significant variation in δ13C values of methane emitted during the entire season.

Phototransformation of the Herbicide Propanil in Paddy Field Water
Environmental Science & Technology, 2017When irradiated in paddy-field water, propanil (PRP) undergoes photodegradation by direct photolysis, by reactions with •OH and CO3•-, and possibly also with the triplet states of chromophoric dissolved organic matter. Irradiation also inhibits the nonphotochemical (probably biological) degradation of PRP.

Nitrogen Fertilizer Recommender for Paddy Fields
2017There are many factors and ways to increase the quality and quantity of paddy yields. One of the factors that can affect the quality of paddy is the amount of fertilizer used. The optimum amount of fertilizer for any field in any year cannot be determined with absolute certainty, thus in this project, we aim to find the optimum amount of nitrogen ...
