Effect of organic manure and panchagavya on the growth and yield of Sweet corn (Zea mays L.)

Abstract

A field experiment was conducted during Rabi 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) on the topic “Effect of Organic manures and Panchagavya on growth and yield of Sweet corn”, to study treatments consisting of two leval of poultry manure (3.0, and 1.5 t/ha) and Farm yard manure (2.5 and 5.0 t/ha) with spary of panchagavya (3%, 5%, 7%). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 8.0), low in organic carbon (0.62%), available N (225 kg/ha), available P (38.2 kg/ha) and available K (240.7 kg/ha). There were 9 treatments, each being replicated thrice and laid out in Randomized Block Design. The results revealed that significant and higher plant height (159.13 cm), higher plant dry weight (87.10 g), maximum number of cobs/plant (2.10), maximum number of row/cobs (12.48) , maximum number of grain per row (29.36) seed index (21.19 g), seed yield (5.10 t/ha), stover yield (17.42 t/ha), gross returns (162340.00 INR/ha), Net returns (115740.00 INR/ha) and Benefit cost ratio (2.48) was recorded in treatment 9 - (Poultry manure 1.5 t/ha + FYM 2.5 t/ha + Panchagavya 7%).
