Abstract
Abstract A field experiment entitled “Effect of different mulches and fertigation scheduling on growth, yield and quality of turmeric” was conducted at the Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif season of the years 2017 and 2018.
The experiment was laid out Strip Plot Design with three replications and two factor i.e. factor “A” consist of different mulches (M) viz. control (without mulch), soybean straw mulch and 50 micron silver polythene mulch and factor “B” consist of fertigation scheduling (F) viz. control (100 % RDF through soil application), 10 no. of splits with 15 days interval through fertigation @80% RDF, 20 no. of splits with 8 days interval through fertigation @80% RDF, 30 no. of splits with 5 days interval through fertigation @80% RDF and 40 no. of splits with 4 days interval through fertigation @80% RDF with 15 treatment combinations.
The result of the present investigation indicated that, mulching treatment M2 (soybean straw) has recorded significantly superior results in respect of plant height (at 60,120 and 180 DAP), number of tillers plant-1, leaf area (at 180 DAP), number of mother rhizome plant-1, number of fingers plant-1, length of mother rhizome, length of primary fingers, length of processed fingers, weight of primary fingers plant-1, weight of fingers plant-1, total yield plant-1, weight of primary fingers plot-1, weight of fingers plot-1, total yield plot-1, weight of processed fingers plot-1, yield of primary fingers , fingers, total yield and processed fingers (q/ha), dry matter plant-1, recovery percentage, available soil N, P and K (kg/ha) after harvesting and total plant uptake of N, P and K (kg/ha).
Regarding the fertigation scheduling treatment F4 (30 no. of splits with 5 days interval through fertigation @80% RDF) exhibited significantly superior results for plant height (at 60,120 and 180 DAP), number of leaves plant-1 (at 60,120 and 180 DAP), number of tillers plant-1, leaf area (at 180 DAP), number of mother rhizome, primary fingers, fingers plant-1, length of mother rhizome, length of primary fingers, length of processed fingers, weight of mother rhizome plant-1, weight of primary fingers plant-1, weight of fingers plant-1, total yield plant-1, weight of mother rhizome plot-1, weight of primary fingers plot-1, weight of fingers plot-1, total yield plot-1, weight of processed fingers plot-1, yield of mother rhizome, primary fingers, fingers, total yield and processed fingers (q/ha), dry matter plant-1, recovery percentage, available soil N, P and K (kg/ha) after harvesting and total plant uptake of N, P and K (kg/ha).
The interaction effect between different mulches and fertigation scheduling, treatment combination M2F4 (soybean straw mulch with 30 no. of splits with 5 days interval through fertigation @80% RDF) was found significant for number of leaves plant-1 (at 60,120 and 180 DAP), weight of mother rhizome plant-1, weight of primary fingers plant-1, weight of fingers plant-1, total yield plant-1, weight of mother rhizome plot-1, weight of primary fingers plot-1, weight of fingers plot-1, total yield plot-1, weight of processed fingers plot-1, yield of mother rhizome, primary fingers, fingers, total yield and processed fingers (q/ha), recovery percentage, and total plant uptake of N, P and K (kg/ha) of turmeric.
Considering the cost economics, the treatment combination M2F4 i.e. soybean straw mulch with 30 no. of splits with 5 days interval through fertigation @80% RDF was found to be most remunerative and profitable as per the B:C ratio (1:3.35) obtained for processed fingers of turmeric under Akola conditions.
