Abstract

The field experiment was conducted to study the effect of various weed control measures on growth and yield of potato in grid region at the Directorate of Weed Science Research (DWSR) Centre, College of Agriculture, (RVSKVV) Gwalior (M.P.) during the rabi season of 2016-2017. Crop growth parameters, viz., plant population (7.94), plant height (26.73, 41.27 and 42.40 cm), number of compound leaves (26.27, 48.27 and 51.96) and number of stem (4.53, 5.25 and 6.18), fresh (60.40, 222.40 and 306.61g) and dry weight of plant (8.14, 40.88 and 65.28 g), fresh weight of haulm /plant (53.73, 97.07 and 108.61 g) and Dry weight of haulm /plant (6.88, 15.34 and 21.72 g) were recorded at 30, 60 and harvest stage respectively. Yield attributes and yield parameters, viz., Number of tubers plant-1 (4.47, 5.58 and 5.91 g), Fresh (6.67, 125.33 and 198 g) and dry weight (1.27, 25.54 and 43.56 g) and tuber yield ha-1 (145.83 q) and Biological yield (231.51 q/ha), haulm yield (85.68 q/ha) and harvest index (63.40 %) were significantly influenced at 60 DAP and maturity respectively by the different weed control treatments. Resulting in production of higher crop growth parameters, yield attributes and yield than other organic weed control treatments T6 and was found highly effective for attaining higher weed suppression and yield simultaneously and superior over rest of the organic weed control treatments.

Conclusion

On the basis of above findings, it may be concluded that weed reduced growth, yield attributes and ultimately tuber yield. In organic farming situation weed reduced tuber yield about 50-60 %. Based on the result of this experiment two hand weeding at 20 and 40 DAP find out most effective weed management practice for potato under organic farming in Gwalior region. — The cost of chemical weed control is actually less than that of manual weeding, hoeing and mulching. This has been a major incentive to many farmers for switching over to herbicides but under organic farming chemical use restricted. — Hence, it may be concluded that significantly highest plant population (7.94), plant height (26.73, 41.27 and 42.40 cm), number of compound leaves (26.27, 48.27 and 51.96) and number of stem (4.53, 5.25 and 6.18), fresh (60.40, 222.40 and 306.61g) and dry weight of plant (8.14, 40.88 and 65.28 g), fresh weight of haulm /plant (53.73, 97.07 and 108.61 g) and Dry weight of haulm /plant (6.88, 15.34 and 21.72 g) were recorded at 30, 60 and harvest stage respectively. — Yield attributes and yield parameters, viz., Number of tubers plant-1 (4.47, 5.58 and 5.91 g), Fresh (6.67, 125.33 and 198 g) and dry weight (1.27, 25.54 and 43.56 g) and tuber yield ha-1 (145.83 q) and Biological yield (231.51 q/ha), haulm yield (85.68 q/ha) and harvest index (63.40 %) — Tuber yield (145.83 q/ha) and Net return (97446.67 Rs./ha) were obtained from two hand weeding at 20 and 40 DAP, followed by HW at 20 DAP + hoeing at 40 DAP (8.39 q/ha, 91474.44 Rs./ha) and Two hand hoeing at 20 and 40 DAP (135.42q/ha, 90363.33 Rs./ha).
