Effect of Farmyard manure, Seedling age and Spacing on the growth and yield of rice (Oryza sativa L.) under System of Rice Intensification in Sudan savanna ecological zone, Nigeria
Abstract
Field trials were conducted at Irrigation Research Station, Kadawa, Institute for Agricultural Research, Ahmadu Bello University, Zaria and Bakalori Irrigation Project, Birnin Tudu, Talata Mafara, both in the Sudan savanna ecological zone of Nigeria during 2018 and 2019 dry seasons, to investigate the effect of farmyard manure, seedling age and spacing on the performance of FARO 44 (Sipi 692033), under system of rice intensification (SRI). Treatments consisted of four levels each of farmyard manure (FYM) (0, 7.5, 10.0 and 12.5 t ha-1); seedling age (A); (9, 15, 21 and 27 days old) and three spacing (S) (15 x 15cm, 25cm x 25cm and 35cm x 35cm). The experiment was laid out in a split plot design and replicated three times. Data were collected on shoot dry weight, number of tillers per plant, panicle weight per plant and paddy yield. Data were subjected to analysis of variance and means partitioned using Duncan’s Multiple Range test (1955) at 5% level of probability. The results revealed that application of 12.5 t ha-1 FYM, transplanting of younger seedlings at 9-15 days old and plants spaced wider at at 25 x 25cm, significantly produced heaviest shoot dry weight, with the highest number of tillers per plant and highest paddy yield per hectare in 2018 and 2019 at Kadawa and Talata Mafara. It was concluded that the SRI practice enhances rice performance and productivity. It is therefore recommended that rice farmers in the study areas imbibe the practice towards increasing rice yield.
