Effect of organic amendments for sustainable production of Broccoli( Brassica oleracea var. italica)

A field experiment entitled “Effect of organic amendments for sustainable production of Broccoli(Brassicaoleracea var. italica)was conducted at Horticulture Research Station, Mondouri, Bidhan Chandra KrishiViswavidyalaya, ,Nadia, West Bengal from November 2017 to February 2018.The design of experiment was Randomized Block Design(RBD) and with 3 replications. The variety used was Sadhana (F1 hybrid).From the experimental result,it was observed that application of the recommended dose of fertilizers recorded higher values for both the vegetative growth parameters like plant height(44.07cm),plant spread(68.60cm),stem girth(19.49mm)etc. and reproductive parameters like curd diameter(10.42cm),curd weight(153g) and yield(17.32t/ha).The treatment T3(Vermicompost+Azotobacter+PSB) was found next best treatment after T1(recommended dose of fertilizers).But as per economics and sustainability was concerned,T3 recorded the maximum values like B:C ratio(3.50) and net return(Rs 235150) followed by T4(Neemcake+Azotobacter+PSB) with B:C ratio(3.18) and net return (Rs 189650).From the experiment,it may be concluded that application of vermicompost+azotobacter+PSB may be viable and sustainable for cultivation of broccoli for new alluvial plains of West Bengal.
