Impact of integrated nutrient management on flowering, fruit set and yield of coloured capsicum (Capsicum annuum L.) cv. Orobelle under naturally ventilated greenhouse.

摘要

An experiment was conducted during 2004-05 to study the influence of integrated nutrient management on the flowering, fruit set and yield of coloured capsicum (Capsicum annuum) cv. Orobelle under greenhouse conditions. Treatments comprised: three organic manures (Pongamia cake (220, 440 and 880 g/m2), vermicompost (375, 750 and 1500 g/m2) and farmyard manure (FYM) at 25 t/ha), recommended dose of fertilizer (RDF) at 250:250:250 kg NPK/ha (applied at three different levels 50, 75 and 100%) and Azotobacter at 5 g/plant. The results revealed that the application of 25% of nitrogen through Pongamia cake+75% of recommended dose of fertilizer+FYM at 25 t/ha+Azotobacter at 5 g/plant has significantly increased the fruit set (29.10%) and number of fruits per plant (15.07), fruit yield per plant (2.8 kg), yield per square metre (11.76 kg) and yield per hectare (117.6 t/ha). The capsicum plants responded significantly to the integrated nutrient supply.
