Effect of ameliorants on canopy architectures of jack bean (Canavalia ensiformis) cultivated in marginal soils

Abstract

A research dealing with the effect of ameliorants on jack bean cultivated in marginal soils i.e. sandy, grumusol, and podsolic soil can be an interesting report. This research was carried out in dry season in 2017, 2018, and 2019 for sandy, grumusol, and podsolic soil respectively. The research relating with the cultivation of jack bean in sandy soil was conducted in sandy beach area of Kulonprogo Regency, Yogyakarta. Whereas, the research dealing with the cultivation of jack bean in grumusol as well as podsolic soil were carried out in Gunung Kidul Regency, Yogyakarta. Kinds of ameliorants i.e. chicken, goat, cow, and green manure were used as factor of the treatments. The variables of leaf number, productive branch number, and plant height were observed. Results of the research indicated that the application of chicken manure gave better growth of plant canopy of jack bean in sandy, grumusol, as well as in podsolic soil, except in grumusol soil there were no significantly different of ameliorant application on the productive branch number of the plants.
