Abstract
The left over compost after harvesting full or remunerative crop of button mushroom is generally called as spent mushroom compost (SMC). An investigation was carried out at Integrated Farming Systems unit of Project Directorate for Farming Systems Research, Modipuram, Meerut, India, during 2013-14 to evaluate the alternative use of SMC for mass multiplication of Trichoderma harzianum and its further evaluation in the form of Trichoderma enriched button mushroom spent substrate (TEBMSS) for enhancing growth and yield parameters of potential fruit crop Kinnow mandarin. One month old Trichoderma enriched button mushroom spent substrate (TEBMSS) was applied in root zone of Kinnow @ 25 kg/plant in the month of April (flowering/fruiting stage). Uninoculated plants were treated as control. The c.f.u. of T. harzianum, which was in the range of 10 4 /g substrate at starting (0 day), reached 8.72 x 10 6 /g substrate at the end of 4 th week. It indicates better growth and sporulation of T. harzianum in the SMC. In Kinnow, the average leaf area in treated plants was 24.40 cm 2 against 14.23 cm 2 in control. The SPAD and NDVI values were also significantly higher in treated plants. The number of fruits/plant (395), average fruit circumference (22.87 cm) and fruit weight (148.57 g) were significantly higher in treated plants as compared to control. There was over 3 fold higher fruit dropping in control plants during May-June and September-October when Kinnow fruits are generally vulnerable for dropping. The increased leaf area, general greenness and canopy cover; increased fruit numbers, circumference and weight and decreased fruit dropping in TEBMSS treated Kinnow plants clearly exhibited the alternative use of SMC for multiplication of the fungal bioagent and its potential use in increasing the growth and yield of fruit crops like Kinnow mandarin.
