Weather Parameters

An investigation was carried out at the Agro Climate Research Centre, Tamil Nadu Agricultural University, on the effect of weather parameters on the green gram yield sown at various sowing dates during the rabi season of 2019. At various sowing dates, two green gram cultivars, VBN 4 and ADT 3, were sown. For both cultivars, the phonological crop length decreased with delays in sowing dates beyond October 23rd. The yield of green gram sown on 23rd October was significantly higher than the crops sown on 30th October and 6th November. The weather parameters Maximum Temperature (Tmax), Diurnal Range (Trange), Bright Sunshine Hours (BSS), Relative Humidity (RH I), Wind Speed (WS) were found to be negatively correlated with seed yield whereas Minimum Temperature (Tmin), Relative Humidity (RH II), Vapour Pressure (VP) were found to be positively correlated with the yield of green gram. The accurate prediction of green gram yield could be done with the maximum temperature, bright sunshine hours, wind speed and with thermal indices especially hygrothermal unit II with 82 percent, accuracy level.

Experiment was conducted during 2012- 2014 to screen 41 green gram genotypes against anthracnose (Colletotrichum truncatum) under the effect of challenge inoculation both in vivo and in field at university research farm AB block, Gayespur and Jaguli, Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India. Attempt was also made to evaluate the stability in yield and disease reactions under this specific biotic stress. Under in-vivo condition all the 38genotypes were found to be moderately resistant except three Sonali, PM-4 and Pusa- 1174 showed moderately susceptible reaction. Whereas, in field stability analysis showed that four genotypes TARM- 18, CZMK-1, PM-D5 and Sukumar were resistant, three genotypes were moderately susceptible (Sonali, PM-4 Pusa-1174) and 34 genotypes showed moderately resistant reaction. Whereas, among the 34 moderately resistant genotypes, 18 genotypes RMG-62 , RVSM-14, NVL- 638, HUM-16, Utkarsha, CZMS-1, AKMN-09-02, ML-1464, KM12-29, AKM-10-13, PM-2, PUSA 0932, RMG- 975, IPM- 306-6, MB-37, IPM-3/2-2, ML-1741 appeared to be stable for disease reaction and yield with high regression co- efficient (bi>_1 ) and low deviation from regression. (s2di less than 1).
