The treatments comprising six levels of mulches and nine levels of herbicides were laid out in a randomized block design with three replications keeping a net plot size of 6.0 x 6.0 m separately. The data were recorded on various parameters, which were influenced significantly by different levels of mulching and herbicides. In mulching experiment, the minimum value for soil pH and ECe, while, maximum values for soil moisture per cent, NPK and growth parameters viz. plant girth, spread, height and leaf water potential were recorded with black polythene of 200μ mulch. However, maximum TSS, ascorbic acid and minimum acidity were recorded in paddy straw mulch and maximum juice content was recorded with black polythene 200μ mulch, while maximum fruit weight, length, breadth, number of fruits and yield were recorded in black polythene 200μ mulch. Similarly, lowest number, fresh and dry weight of weeds at all monthly interval were observed with Black polythene 200μ and 100μ mulch followed by paddy straw mulch. The results suggest that the Black polythene 200μ mulch has shown the best economical mulch for higher yield with quality fruit production at commercial scale. In weed control experiment, soil pH, ECe, leaf water potential and fruit acidity were remaining unchanged during the time frame. However, manual weeding at monthly interval treatment found best for all other parameters viz. soil NPK, moisture, growth, yield, quality and weed parameters while, in herbicidal treatments, atrazine 2 kg + glyphosate 1% recorded best for the same. Manual weeding at monthly interval treatments gave the best results but it was very costly and herbicidal combination of atrazine 2 kg + glyphosate 1% resulted almost similar to manual weeding at monthly interval treatment. Atrazine 2 kg + Glyphosate 1% found best economical combination for commercial production of kinnow with quality fruits under semi arid condition of Hisar (Haryana).enCultivation, Weeds, Fruits, Heterocyclic compounds, Planting, Crop residues, Herbicides, Yields, Control methods, Soil water contentThesis
