dc.description.abstractThe present investigations were carried out to ascertain the influence of different floor management treatments in Kinnow mandarin orchard on weed infestation, soil microclimate, fruit yield and quality under sub-mountainous zone of Punjab. Six years old kinnow mandarin plants were subjected to different treatments viz. clean cultivation, chemical weed management, mowing of weeds, black polyethylene mulch, silver polyethylene mulch, subabul leaf mulch and control (weedy check). Although, no weed growth occurred under synthetic mulches (black and silver polyethylene mulches), but the mulching with leaves of subabul plant; the locally available wild species in abundance also exhibited significant reduction in grassy (13.41 m-2) as well as broad leaf weed (17.72 m-2) count and biomass (8.90 and 12.67 gm-2) as compared to grassy and broad leaf weed count of 54.75 and 58.67 -2 and weed biomass of 35.72 and 39.94 gm-2 under control plants, respectively. Soil micro-climatic parameters in terms of soil moisture (20.93 % and 21.18 %) and soil temperature (27.69 o C, 27.35 o C) at 10cm and 20 cm depth were recorded maximum under black polyethylene mulch, respectively. Whereas, the minimum soil moisture was recorded under control plants. The fruit yield and yield attributing characteristics were significantly higher under black polyethylene mulch with maximum fruit retention (3.01 %), fruit number per plant (447.33/plant), fruit size (6.29 × 7.74 cm), fruit weight (160.13g) and ultimate yield (71.63 kg/plant). Fruit quality in terms of TSS (10.72˚B), vitamin C (40.28 mg/100g pulp), total sugars (8.72 %), non-reducing sugars (4.44 %) was also significantly better under black polythene mulch followed by silver polyethylene mulch and subabul leaf mulch. Thus, it can be concluded that the black and silver polythene mulches were superior in terms of weed suppression, soil moisture conservation, sustained soil temperature, improving fruit yield and quality of Kinnow. However, subabul leaf mulch was economically more feasible as an orchard floor management practice for kinnow orchards under sub- mountainous region of Punjab.en_US
