Influence of climatological factors on evapotranspiration (Et) of rice
(Kerala Agricultural University, 1976) Sreedharan, C; Vamadevan, V K
It is concluded that if weather records are used to estimate evapotranspiration, solar radiation, air temperature, pan evaporation and wind velocity should be taken into consideratation. Out of these, solar radiation and air temperature are the most important factors which influence ET in this locality.
Effect of split doses and times of nitrogen application on the content uptake and utilisation efficiency for direct sown rice in puddled soil
(Kerala Agricultural University, 1977) Balachandran Nair, G K; Sreedharan, C
A field experiment conducted to study the effect of split dose and times of N application on N uptake and utilisation efficiency showed ' that the skipping basal application of N and applying half at active tillering and the other luiif at panicle initiation stages gave maximum grain yield for direct sown rice in puddled soil. This was made possible by a higher total N uptake and a higher incremental N uptake contributting to grain yield.
