Effect of fly ash, farm yard manure and soil amendments to maize crop on morphological and yield contributing characters of Kharif maize ( Zea mays L.)

Abstract

An experiment was conducted at farm of Mr. Gurmail Singh at Village Kiker Khera, Teh. Abohar, District Fazilka, Punjab in kharif season of year 2018 to study the effect of fly ash, farm yard manure and soil amendments to maize crop on morphological and yield contributing characters of kharif maize. The treatments were fly ash, fly ash + FYM, FYM + Lime, FYM + Gypsum, FYM, Control. The effect of these factors on plant height, number of leaves per plant, stem girth, days to cob maturity, number of cobs per plant, average cob length, number of seeds per cob, test weight and grain yield were observed. Fly ash treatment gives highest plant height (181.4 cm) and stem girth (5.94 cm) than other treatments. Maximum test weight (250.00 g) and average cob length (22.2 cm) were obtained in combined application of fly ash and farm yard manure. Average numbers of cobs were found maximum in combined application of farm yard manure and gypsum. For yield purpose fly ash treated plot gives maximum grain yield (23.73 q/acre) of maize, thus it can be stated that fly ash gives better growth and yield of maize crop as compare to other treatments.
