dc.description.abstractABSTRACT The present investigation entitled, “Studies on effect of different level of irrigation and fertigation on yield and quality of broccoli (Brassica oleracea var. italica)” was carried out at the research farm of the Precision Farming Development Centre, Department of Soil Science and Water Management, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during rabi season of 2017-2018. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The study comprised of ten treatment combinations consisting of three levels of irrigation (I1: Drip irrigation with 100 per cent ETc, I2: Drip irrigation with 80 per cent ETc and I3: Drip irrigation with 60 per cent ETc) and fertigation (F1: 100 per cent of RDF, F2: 85 per cent of RDF and F3: 70 per cent of RDF) along with one surface control (surface irrigation + conventional application of fertilizers- Conventional Practice). Drip irrigation with 100%, 80% and 60% ETc in conjunction with polyethylene mulch consumed 14.71, 11.76 and 8.82 cm water throughout the cropping season that were lower as compared to the surface irrigated plots which consumed 30cm water. This resulted into saving of irrigation water to the tune of 50.9%, 60.8% and 70.6%, respectively, over the surface irrigation. Growth parameters of broccoli were significantly affected by different levels of irrigation and fertigation. In all the cases, treatment I2F1 (drip irrigation with 80 per cent ETc with drip fertigation @100% RDF) was found significantly superior over the rest of the combinations but was at par with I3F1 and I2F3 for some parameters. The treatment combinations of drip irrigation with 80 per cent ETc and fertigation @ 100 per cent of RDF registered maximum yield (249.67 q ha-1) as compared to rest of the combinations but was statistically at par with the treatments I2F2(248.11 q ha-1) and I3F1(246.55 q/ha). Treatment combination of drip irrigation with 60 per cent ETc + drip fertigation @ 100 per cent of RDF recorded maximum water use efficiency (27.95 q ha1 cm-1) and fertilizer use efficiency (73.97 kg kg-1 of nutrient). Highest benefit cost ratio (2.63) was recorded with the treatment combination of drip irrigation @ 60 per cent ETc with 70 per cent recommended dose of fertilizer through fertigation.en_US
