Abstract

Combinations of fertilizer application and plant spacing are expected to increase grain yields and plant growth of special quality rice varieties on irrigated lowland rice field. The research was aimed to observe the effects of fertilizer application and plant spacing on the special rice varieties. The trial was conducted in a farmer's field, at Mekarwangi Village, Ciranjang District, Cianjur Regency, West Java, during the dry season of April-September, 2016. The treatments were arranged in a split-split plot design with three replications. The main plot, was two inorganic fertilizer application (present local recomendation 45 kg N/ha, Phonska and organic fertilizer versus SSNM 112,5 kg N/ha, and Phonska. As sub plot was planting methods legowo 2:1 (27-54) cm x 13.5 cm and legowo 4:1 (27-54) cm x 13,5 cm]. As sub-sub plot There were four special quality rice varieties namely Cisokan, Inpari 21, IR 42, Lusi and Tayke. The smallest plot size was 4 m x 5 m, with the total number of 60 plots. The results showed that combination application of present local recommendation fertilizer and jajar legowo 4:1 planted with IR 42 gave higher yield (9.80 ton/ha dry grain) than Lusi. Legowo 4:1 with SSNM fertilizer application (9.33 ton/ha dry grains) and Cisokan planted on legowo 4:1 with application of present local fertilizer recommendation (9.24 t/ha dry grains). The special quality rice varieties (Cisokan, Inpari 21, IR 42 and Lusi) planted on legowo 2:1 and legowo 4:1 produced siginificantly higher yields than the Tayken. The effect of jajar legowo 4:1 plant spacing resulted in higher yield (8,50 t/ha dry grain) than that of legowo 2:1 (8,03 t/ha dry grain).

Rice Growth and Physiological Response in The Salibu Cultivation System

“…However, the difference in this variety is no different from the other characters. Yield components can describe types of rice varieties that vary, such as many or few tillers, long or short panicles, grain density in panicles, and grain size, thus, the influence of cultivation components on one or several yield components can relate to each other [8]. .…”

“…This can occur due to genetic and environmental factors that affect the adaptability of plant growth. )difference in yields obtained is due to each variety having different genetic, morphological and physiological properties and having different yield potentials (Alavan et al, 2015;Ikhwani and Rustiati, 2018.graincontents is one of the characters of rice plants that is controlled by many genes (Herawati et al, 2019) Table 5.
