Correlation and Peat Analysis of Leaf Characters and Physiology to yield to Four Environments of Organic Swallow Guano Fertilizer

ABSTRACT. An experiment to estimate correlation and path analysis of leaf characters to yield of four micro environments (without organic fertilizer and three rate of organic fertilizer) was conducted at Arjasari Experiment Station, Agriculture Faculty, Padjajaran University from January 2003 to August 2003, in 26 soybean genotypes and Wilis at four levels of organic swallow guano fertilizer. The level of organic fertilizer were: without swallow guano, 225, 450, and 675 kg ha^-1 swallow guano. Each environment was arranged in completely randomized block design, replicated two times, check genotype (wilis) was planted between six genotypes for each replication. Result of this experiment showed that: leaf number did not have any correlation wit net assimilation rate (NAR). Leaf angle (LA), stomatal length (SL) and stomata frequency (SF) had a negatively correlation with NAR, whereas DTDW and chlorophyll (Chl) were positively correlated to NAR: NAR, seed fiiling period (SFP) and dry matter accumulation rate (DMAR) were positively correlated to yield, and high path coefficient was found either between DTDW and NAR, or between SFP and yield.
