dc.description.abstractThe experiment entitled “Effect of manures, bio-fertilizers and mulching on growth and yield of potato” was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2010-11 and 2011-12 to find out the sutaible level of manures and mulching for getting higher yield as well as keeping quality of potato tubers at ambient room temperature. The potato variety used for the investigation was Kufri Bahar. The treatments comprising two levels of mulching and non- mulching and sixteen levels of organic manures were laid out in a split plot design with three replications keeping a net plot size of 3.0 x 3.0 m. The ten competitive plants were selected randomly from each treatment to record data on various parameters, which were influenced significantly by different levels of mulching and organic manures. The maximum value for plant height at 45, 60, 75 and 90 days after planting, number of stems per hill, number of leaves per stem, leaf weight per hill (g), stem weight per hill (g), leaf area index, number and weight (kg) of <25, 26-50, 51-75 and >75 g size tubers, total number and weight of tubers (kg / m2) total and marketable tuber yield (kg/m2 and q/ha) were recorded maximum with the application of vermi-compost @ 6.0 t/ha + biofertilizers + ( Azotobactor + PSB). However, the number and weight (kg) of up to 25 g size tubers was noticed maximum with out organic manures application. Dry matter and starch content of potato tubers (%) at harvest was recorded maximum with vermi-compost @ 6.0 t /ha + bio-fertilizers + ( Azotobactor + PSB), while the total ethanol soluble sugars content of potato tubers at harvest on dry weight basis (mg/100 g) was minimum vermicompost @ 6.0 t /ha + bio-fertilizers + ( Azotobactor + PSB). The minimum value for physiological loss in weight and decay loss of potato tubers (%) at 15, 30, 45 and 60 days after harvest was recorded with vermi-compost @ 6.0 t /ha + bio-fertilizers + ( Azotobactor + PSB). The interaction effect of mulching and manures showed significant variation for leaves weight, leaf area index, tuber yield and keeping quality parameters. Significantly the highest values for leaves weight per hill (g), leaf area index, weight (kg) of <25, 26-50, 51-75 and >75 g size tubers per square meter, total weight of tubers (kg) per square meter were registered with the treatment combination of mulching and vermi-compost @ 6.0 t /ha + bio-fertilizers + (Azotobactor + PSB) . Similarly, minimum value for physiological loss in weight and decay loss of potato tubers (%) at 15, 30, 45 and days after harvest was noted with treatment combination of mulching and application vermi-compost @ 6.0 t/ha + bio-fertilizers + (Azotobactor + PSB). The two years results suggest that the mulching in combination with vermi-compost @ 6.0 t /ha + bio-fertilizers + (Azotobactor + PSB) has shown the best treatment combinations for potato production and storage at ambient room temperature, respectively under semiarid conditions of Hisar (Haryna).en_US
