dc.description.abstract | An experiment on development of a ridge-vent type naturally ventilated riet"Cum-polyhouse and its performance on capsicum (^Cdpsicum dnnuum l.) production during December 2011 to May 2012 was conducted at the farm of Dept. of RE&RE, located at Junagadh Agricultural University, Junagadh (21.5°N, 70.1 °E). For experimental study, a naturally ventilated net-cumpolyhouse having size (12.1 m x 4.86 m) with ridge-vent was constructed at the experimental site. The experiment was laid out in two-factor split-plot design with three replications comprising of total six treatment combinations. Irrigation was the main factor with irrigation levels i.e. IW:CPE ratio, \^ = 0.6, I2 = 0.8 and I3 =1.0 whereas mulching was the sub-factor with Mi = normal black plastic mulch and Mo as no mulch (bare soil). The daily environmental parameters I.e. ambient temperature, relative humidity and solar radiation and soil parameters as soil temperature were taken and computed mean, average was used for the analysis. The response of capsicur evaluated in terms of plant height, number of flowers per pli^^, fruits per plant, weight of fruits per plant and yield per treatmerl analysis was also done to determine to financial viability of the During the crop season, the average of mean weekly reduction, increase in relative humidity and reduction in solar radiation between external and internal environment of the structure was found as 5.3 °C, 17.35 % and 65.3 % respectively. The soil temperature was found highest in treatment hMi i.e. IW; CPE ratio 0.6 + Mulch where as it was found lowest in the treatment I3M0 i.e. IW:CPE ratio 1.0 + No mulch during the crop period. There was no effect of the treatments, either alone or in combination, on the plant height. All the three levels of irrigation were at par with each other in terms of the number of flowers and number of fruits but effect of mulch was significant on both number of flowers and number of fruits. Irrigation levels and mulch, individually and in interaction, had a significant effect on the weight of fruits. The treatment I3M1 i.e. IW:CPE ratio 1.0 + Mulch was highly superior as compared to the other treatment combinations. The highest benefit cost ratio and lowest payback period was found for I3M1 as 5.07 and 2.6 years respectively. | en_US |
