The experiment was conducted in two growing conditions of open field and poly house with four ferigation levels and having one control with conventional method of irrigation and fertilizer application with 100% NPK as per POP. From this study result revealed that under Kerala condition during February 2017 to August 2017 better performance of growth parameters and yield contributing characters resulted in higher yield under open field condition with conventional method of irrigation and fertilizer application than open field and poly house with fertigation. The study revealed that the growth and yield of chilli was better for plants receiving higher quantity of water. The quantity of water fixed was 100% PE for the fertigation. It was not sufficient to meet the growth requirement and to meet the evaporation demand of crop under poly house condition. Water productivity and nutrient use efficiency under conventional method of irrigation and fertilizer application followed by open field with fertigation was found higher compared to poly house plants receiving fertigation. This was due to the higher yield under open field condition. Result of the study indicated that microclimatic condition prevailed during the growth period had significant influence on the growth and yield parameter of chilli. The yield, water productivity and nutrient use efficiency were not affected by the levels of fertigation. Through fertigation, providing lesser nutrients that is application of 75% NPK with 25% as basal is enough for the maximum production. So there will be a reduction of 25% of nutrients. Net return and Benefit cost ratio were found to be much higher under conventional method of fertilizer application compared to open field and poly house with fertigation. | |
