Grade of tubers, Organic and inorganic, Potato, Row proportions, Varieties


The effects of row proportions and nutrient management was studied in potato (Solanum tubersoum L.) + Indian mustard [Brassica juncea (L.) Czernj.] intercropping system during 2014–15 and 2015–16 at Amar Singh College Farm, Lakhaoti (Bulandshahr), Uttar Pradesh. The field experiment was laid out in a split-split plot design with 3 replications. The main plot treatments consisted of 3 varieties, viz. ‘Kufri Pukhraj’, ‘Kufri Anand’ and ‘Chipsona 3’, and subplots comprised row proportions of 2 : 1 potato : Indian mustard (P : M), 4 : 1 P : M, potato sole and Indian mustard sole and the sub-subplot treatments consisted of 3 nutrient sources 100% organic (FYM), 100% inorganic and 50% organic + 50% inorganic. The maximum fresh weight of tubers (450.33 g), total tuber dry weight (56.99 g), total number of tubers/plant (15.40) as well as total biological yield (49.14) were recorded in ‘Kufri Pukhraj’ both for A - grade and total tuber yield. Row ratio of 2 : 1 (P : M) recorded higher fresh weight of haulms/ plant (191.48), while higher dry weight/plant of potato (119.70) was recorded in the sole crop. Number of tuber/ plant, fresh and dry weight of tubers were significantly higher under sole potato than row ratio of 4 : 1 however, row ratio of 4 : 1 was slightly superior to row ratio of 2 : 1. Sole potato and row ratio of 4 : 1 resulted in significantly higher total biomass than row ratio of 2 : 1. Yield of different grades and total tubers was recorded significantly higher in sole crop than that for row ratio of 4 : 1 and 2 : 1, though variations were observed nominal in case of Cgrade tubers. Significantly higher potato yield (2.85 t/ha) was observed with the application of nutrients through 50% organic + 50% inorganic fertilizer application.
