Abstract
The experiment entitled “Effect of integrated nutrient management on growth, yield and quality of potato (Solanum tuberosum L.) in northern hills of Chhattisgarh” was carried out at Raj Mohini Devi College of Agriculture and Research Station, Ambikapur (Surguja), Indira Gandhi Krishi Vishwavidyalaya (Chhattisgarh).During therabi season of the year 2015-16 and 2016-17
The experiment was laid out in split-split plot design with three replication. The treatments consisted of three levels of FYM (t ha-1) i.e. (5 t), (10 t) ha-1 with controlas main plot and four levels of fertility i.e. 50% RDF, 75% RDF and 100% RDF (at 30, 45, 60 and 75 DAP) as sub-plot and two levels of biofertilizers B1(Azotobacter + PSB)and B0 (control)potato cultivar KufriPukhraj was used for experiment duringrabi season of 2015-16 and 2016-17.
Among different levels of FYM, F2 i.e. 10 t FYM ha-1 had found significantly superior for over other treatments which was recorded the maximum growth parameters (plant emergence per cent, plant height (cm), number of shoots plant-1, number of compound leaves plant-1, tuber initiation (in days), leaf area index, fresh weight of shoots (g) plant-1, dry weight of shoots (g) plant-1)and yield attributes i.e. number of stolons plant-1, number of tubers plant-1, fresh and dry weight of tubers plant-1, tuberization efficiency,dry matter content of tuber, shoot and roots plant-1, grade wise number of tubers plot-1,grade wise yield (kg) plot-1, number of marketable and unmarketable tubers plant-1, marketable and unmarketable yield (kg) plot-1, marketable and unmarketable yield (q) ha-1, harvest index, biomass plant-1, dry matter partitioning, tuber yield(g) plant-1 (401.87), tuber yield (kg) plot-1 (30.14) and total tuber yield (q) ha -1 (334.89) with highest net profit (226235.42Rs.), b:c ratio (3.04) and quality parameters (reducing sugar content, total sugar, starch, protein and fiber per cent with content of chlorophyll) was also obtainedunder F2 (10 t FYM ha-1).
The 100% RDF of NPK(C3) had remarkable superiority over all the levels of fertility for growth parameters (plant emergence per cent, plant height (cm), number of shoots plant-1, number of compound leaves plant-1, tuber initiation (in days), leaf area index, fresh weight of shoots (g) plant-1, dry weight of shoots (g) plant-1) and yield attributes [number of stolons plant-1, number of tubers plant-1, fresh and dry weight of tubers, tuberization efficiency, dry matter content of tuber, shoot and roots plant-1, grade wise number of tubers plot-1,grade wise yield (kg) plot-1, number of marketable and unmarketable tubers plant-1, marketable and unmarketable yield (kg) plot-1, marketable and unmarketable yield (q) ha-1, harvest index, biomass plant-1, dry matter partitioning, tuber yield (g) plant-1 (406.44), tuber yield (kg) plot-1 (30.48) and total tuber yield (q) ha -1 (338.70)] with highest net profit (225567.35 Rs.), b:c ratio (3.00) and quality parameters (reducing sugar content, total sugar, starch, protein and fiber per cent with content of chlorophyll) was also obtained under C3 (100% RDF)than the other levels of RDF. However the maximum unmarketable tuber yield (kg plot-1& q ha-1) was noticed with 50% RDF and control (0% RDF). Thus 100% RDF found superior for this trait also as the lowest number and weight of unmarketable tubers noted in this treatment.
Among the levels of biofertilizers combination of both Azoto+PSB has recorded remarkably higherin growth parameters, yield attributesand quality parameters with net profit (198100.80Rs.) and benefit: cost ratio (2.8) was also obtained maximum under B1(Azotobacter+ PSB)than all the other treatments.
The interaction data over the year indicated that between interaction effects of levels of FYM F2 (10 t FYM ha-1)with levels of fertility C3(100% RDF) or application of biofertilizerB1(Azotobacter+ PSB) showed significant effect for all growth, yield and quality parameters during both the years as well as in the pooled data under this study.
