Effect of organic manures on growth, yield and economics of pomegranate (Punica granatum L.) 'Super Bhagwa' under northern dry zone of Karnataka
An experiment was conducted to study the growth behavior, fruit yield and the benefit:cost ratio (B:C) of pomegranate (Punica granatum L.) 'Super Bhagwa' as influenced by different organic sources of nutrients under northern dry zone of Karnataka during hasta bahar (September-October) season of 2016-17. The experiment was laid out in a complete randomized block design with seven different sources of nutrients and 3 replicates: recommended dose of nitrogen (RDN) through Farm Yard Manure (FYM) (T1), RDN through vermicompost (T2), RDN through poultry manure (T3), RDN through green manure with sunn hemp (T4), RDN through sheep manure (T5), RDN through neem cake (T6) and RDN of mineral fertilizer (control; T7: 400:200:200 g N:P2O5:K2O plant-1). Results revealed that RDN through vermicompost recorded significantly higher number of shoots (45.73 plant-1), highest shoot length (95.30 cm), plant height (3.97 m) and plant canopy in both directions compared to all other tested treatments. RDN through poultry manure recorded significantly more number of productive flowers (85.15 plant-1), highest fruit set (67.16%) and yield (13.43 kg plant-1) compared to other treatments, which was followed by RDN through neem cake and control (T7). Highest gross income (as Indian Rupi (Rs.932512 ha-1)), net income (Rs.620695 ha-1) and B:C (2.99) were recorded by RDN supplied through poultry manure. Thus, the present investigation revealed that the vermicompost was superior over other organic sources in improving vegetative growth and closely followed by poultry manure and poultry manure was superior over other organic sources in improving flowering, fruit set, yield and B:C of the pomegranate 'Super Bhagwa'.
