Abstract
An investigation entitled “Studies on Crop weather calendar of major crops of north eastern plain zone of U.P.” was carried out through the collection of historical weather data major crop data and insect pest data. The results revealed that, climatic normal for wheat, T max (37.90C) and T min (19.10C), in 15th week was found. for chickpea, The highest total rainfall in 41th week (6.5 mm), highest T max in (340C), 13th week and T min (21.10C) in 41th wee; For mustard crop T maxi (31.20C) in 43th week and T mini (19.30C) in 42th week; For rice crop highest rainfall (71.5mm) in 29th week T maxi (35.60C) in 25th week and T min (26.60C) in 25th, For maize crop rainfall (71.5mm) in 29th week T maxi (35.60C) in 25th week and T min(26.60C) in 25th & 26th week RHm (90.1%) in 33th week were found suitable. In wheat at seedling stage T maxi (30-320C) and T min (14-170C) and highest T maxi during milking stage of the crop (32-340C) and T min (14-15 0C). In chickpea T maxi during pod maturity (30-350C). In mustard during flowering maxi (20-250C) and T mini at (5.5 to 60C). During the pod filling stage was found (22- 240C) and T mini (4-70C). Whereas RHm (95-97%) and RHe (45-52%). At this stage, In rice During the seedling phase and transplanting T maxi and T min (30-340C) and (24-260C) respectively, In maize At maturity T max, T min RHm, RHe was recorded (12-360C), (18-.220C), (90-92%) and (40-52%)
respectively, were found congenial weather for better yield. For army worm in wheat T maxi ( 22-300C) and T min (7.5-150C), RHm (92-94%), Gram pod borer T maxi (23-290C), T min (6-130C), RH m( 90-94%).,for Aphid T maxi (23.20C), T min (6.70C), 7 Okta cloud cover in the sky is the congenial condition for the mustard aphid. RH maxi (91.3%) RH min (70-85%) and (2-11) mm of rainfall. for Yellow stem borer T maxi (320C), T min (26.20C), RHm (90.6%) RHe (67.8%) and (48) mm of rainfall. For maize borer T maxi (34.50C), T min (25.20C), RH m (90.1%) RHe (72.6) and rainfall (29.1) mm. for shoot fly in maize T maxi (32-340C), T min (24-260C), RHm (89-90%), T min were found. Congenial weather conditions for infestation.
