Comparative efficacy of muriate of potash and sulphate of potash on yield attributes, yield and economics of chilli (Capsicum annuum L.).

摘要

Field experiments were carried out with chilli (C. annuum) cv. PKM 1 during the kharif and rabi seasons of 2001-02 in Coimbatore, Tamil Nadu, India. The treatments included 2 sources (muriate of potash (MOP) and sulfate of potash (SOP)) and 5 levels (0, 30, 45, 60 and 75 kg/ha) of K, with application of farmyard manure (FYM). Additional 2 treatments, i.e. 30 and 60 kg K2O/ha as SOP, were tried without FYM. K at 60 kg SOP/ha increased the number of fruits per plant, fruit length and fruit weight during both seasons. This treatment also recorded the highest fruit set percentage, harvest index and dry fruit yield (5.77 and 5.09 t/ha during the kharif and rabi seasons, respectively). Economic analysis showed that application of K at 60 kg SOP/ha was significantly superior in increasing the net return and benefit cost ratio (5.80 and 5.11 during kharif and rabi, respectively)..
