Abstract

The effects of stockosorb and mulching on the growth, yield and quality of Assam lemon were investigated in this study. This experiment was carried out at the Fruit Research Farm of College of Horticulture and Forestry, Pasighat, Arunachal Pradesh in the year 2014–15. The experiment was carried out in factorial randomized block design with 12 treatments which were replicated three times. The treatments included, S0M0=No stockosorb with no mulch, S0M1=No stockosorb with black polythene mulch, S0M2=No stockosorb with sawdust mulch, S0M3=No stockosorb with rice husk mulch, S1M0=50 g stockosorb with no mulch, S1M1=50 g stockosorb with black polythene mulch, S1M2=50 g stockosorb with sawdust mulch, S1M3=50 g stockosorb with rice husk mulch, S2M0=100 g stockosorb with no mulch, S21=100 g stockosorb with black polythene mulch, SM2=100 g stockosorb M2 with sawdust mulch and S2M3=100 g stockosorb with rice husk mulch. Experimental results showed that the incorporation of the different stockosorb concentrations and mulching regimes had a positive effect on growth parameters. Highest increase in plant height (8.85%) and canopy spread (12.84%) was recorded by S1M1, i. e. 50 g stockosorb with black polythene mulch. The treatment combinations also had a significant influence on yield parameters where S1M1 recorded the highest number of fruits per plant (68.16) and fruit yield per plant (7.99 kg). S1M1 also recorded significantly higher soil moisture content (27.93%). Thus, it was concluded that although some of the treatment combinations showed significant results, S1M1 (50 g stockosorb+black polythene mulch) is considered as the ideal treatment combination for significant production.
