Effect of Integrated Nutrient Management and Bio-regulators on Yield and Economics Attributes of Sprouting Broccoli {Brassica oleracea (L.) var. italica}

Abstract

The field experiment was conducted at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur) during Rabi seasons of 2016-17 and 2017-18. The experiment consisted of thirty five treatment combinations including seven INM (100 per cent RDF through inorganic fertilizer, 75 per cent RDF through inorganic fertilizer + 25 per cent through FYM (5 t/ha), 50 per cent RDF through inorganic fertilizer + 50 per cent through FYM, 100 per cent RDF through FYM, 75 per cent RDF through inorganic fertilizer + 25 per cent through VC, 50 per cent RDF through inorganic fertilizer + 50 per cent through VC and 100 per cent RDF through vermicompost and five bio-regulator levels [Control, Brassinoids @ 5 ppm, Brassinoids @ 10 ppm, Salicylic acid @ 100 ppm and Salicylic acid @ 150 ppm] were under taken in Split plot design with three replications. The results showed that the maximum weight of primary curd (222.51 g), number of secondary curds per plant (6.58), weight of secondary curd (154.05 g), yield per plant (384.56 g), yield per plot (7.69 kg), yield per ha Ola et al.; CJAST, 35(5): 1-8, 2019; Article no.CJAST.49153 2 (189.90 q), biological yield per ha (1081.85 q) and net returns ( 304019/ha) were recorded with the application of 50 per cent RDF through inorganic fertilizer and 3.5 t/ha vermicompost (F 5 ) in sprouting broccoli. Whereas, the maximum B:C ratio (4.39:1) was recorded under 75 per cent RDF supplied through inorganic fertilizer and 1.75 t/ha vermicompost. Harvesting index was found non significant. In the case of bio-regulators maximum weight of primary curd (213.17 g), number of secondary curds per plant (6.20), weight of secondary curd (147 g), yield per plant (362.57 g), yield per plot (7.42 kg), yield per ha (183.19 q), biological yield per ha (1002.18 q), net returns ( 287563 / ha) and B:C ratio (3.99:1) were recorded significant by superior over control with foliar application of 5 ppm brassinoids. While harvesting index was found non significant to broccoli. Original Research Article

Soil fertility, growth and yield of broccoli (Brassica oleracea L. var. italica) as influenced by integrated nutrient management practices

“…In addition, farm yard manure improves the chemical, biological and physical characteristics of the soil, which facilitates optimal nutrient uptake by the plants and an increase in output. The results of present study are similar with Mohanta et al, (2018) [17] , Devi et al, (2018) [6] and Shankar et al, (2019) [20] . [11] , Yadav et al, (2020) [27] and Merentoshi et al, (2022) [15] .…”

Effect of Different Organic Fertilizer on the Growth and Yield of Broccoli (Brassica oleraceae var. italic)

“…Among different types of organic fertilizers treatment the highest marketable yield was recorded from T5 (19.242 t ha -1 ) followed by T4 (17.370 t ha -1 ), T3 (16.724 t ha -1 ), T2 (16.285 t ha -1 ), T1 (13.947 t ha -1 ) respectively and the lowest marketable weight of curd was observed from T0 (7.878 t ha -1 ) treatment (Figure 10). This finding showed that combined application of vermicompost with cowdung provided the best marketable yield which had also supported by Akter (2021) and (Ola et al, 2019).…”

Impact of fermented organic formulations combined with inorganic fertilizers on broccoli (Brassica oleracea L. var. italica Plenck) cv. Palam Samridhi

“…Pooled data showed that the maximum net income of ₹ 2,45,840 was obtained in treatment T 8 followed by T 7 (90% of recommended dose of fertilizers + 5% drenching with jeevamrit @ 1.0 L m −2 + 5% foliar spray with jeevamrit) with net income of ₹ 2,34,757. According to Ola [ 39 ], the highest benefit cost ratio might be due to changes in the form of plant growth, yield and quality parameters. This improvement led to the proportional increase in yield and higher B:C ratio.…”
