Abstract
The research investigation entitled “Studies on intercropping and crop geometry in organic production of broccoli (Brassica oleracea var. italica)” was conducted at the research farm and laboratory of Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during 2012-13 and 2013-14. The experiment was laid out in split plot design replicated thrice with three different organic manure and two spacing as main plot treatments and five intercrops including sole crop of broccoli as sub-plot treatments, thus making a total of thirty treatment combinations, from the various parameters recorded number of leaves, days to first and 50 per cent harvesting, maximum weight of main head (g), girth of head (cm), number of sprouts per plant, weight of sprouts per plant (g), yield of sprouts per plant (g), total yield per plant (g), total yield (q/ha), plant biomass (g), mineral content in whole plant, vitamin A (mg/100g) and vitamin C (mg/100g) of broccoli were maximum in the M2S1C1 While, phosphorus content (mg/kg) in plant in the treatment M3S1C1. However, plant height (cm), minimum days to harvesting and yield (q/ha) of intercrops was maximum in the M2S2C4 treatment. So, it is concluded from the present investigation that application of vermicompost under a spacing of 45 x 45 cm the sole crop of broccoli (M2S1C1) recorded higher total yield (303.9 q/ha). The highest total yield of greens and roots was recorded with the application of vermicompost under paired row spacing and radish as the intercrop planted in broccoli (M2S2C5) followed by the application of poultry manure also under paired row planting system and radish as intercrop (M3S2C5). The maximum net return (Rs. 162795) was obtained under the M2S1C4 treatment, however, benefit: cost ratio (1: 0.84) was under the treatment M3S1C4, which was statistically at par with the M2S1C4 treatment (1: 0.83).
