Chilli (Capsicum annuum L.) is an important commercial spice and vegetable crop. In chilli, flower abscission will be high if day temperature is in the range of 32-38 o C, whereas fruit retention will be maximal at 16-21 o C day temperature (Demers et al., 1994).Early summer to early rainy season is the lean period of production. Prevailing high temperature and shortage of soil moisture during early summer are the major factors limiting its cultivation during summer months. Area under cultivation for chilli during summer season was very much negligible in comparison with the cropping area during
