Abstract

An experiment was carried out from May to October 2015 at Experimental Field of Agriculture Faculty Winaya Mukti University Tanjungsari Campus, at the altitude of 850 m above sea level,  Inceptisols soil order. The objective of these experiment was to study interaction effect of   Chicken manure and Phonska Rates on Yield of Sweet Potato Cilembu Variety. Experimental design used was a Randomized Block Design (RBD) in factorial pattern with 2 replications.  The fisrt factor named chicken manure rates (A), contain of 4 levels, named : a0 = without chicken manure,  a1 = 10 t ha-1,  a2 = 20 t ha-1, a3 = 30 t ha-1. Rates of Phonska (P) contain 4 levels, named : p0 = without Phonska,  p1 = 400 kg ha-1, p2 = 800 kg ha-1  p3 = 1.200 kg ha-1. Result of experiment showed that interaction between chicken manure and phonska rates was not significant on yield of sweet potato Cilembu variety.  Main effect of chicken manure rates and phonska rates were significant on plant dry weigt at one, two, three and four month after planting, weight of  first class tuber and total tuber plot-1, while the effect on number of tuber is not significant.  The optimum chicken manure rate was 28,87 ton ha-1 with maksimum first class yield  17,96 t ha-1, and optimum chicken manure rate  was 27,18 t ha-1 with total tuber yield 20,51 t ha-1. Tuber yield response toward phonska rates was linear.

Abstract

The objective of the research was to know the variability and heritability some field rice genotype important characters on high salinity pressure. The research was carried on Laboratory and Screen House of Balai Pengawasan dan Sertifikasi Benih Tanaman Pangan dan Hortikultura, Bandung with the altitude is 600 m above sea level. The time of the research was started on October 2011 until February  2012. The research used experimental methods and Randomized Block Design with 16 field rice genotype and replicated 2 times. The main observation variables are plant height, weight of dry shoot, weight of dry root, relativity of shoot and root, age of flowering, age of harvest, number of tassel per plant, number of rice per plant, percentage of empty rice per plant, weight of 1000 grain seeds per plant and result of unhulled rice per plant. The research and also showing different expected value heritability for important characters of field rice on high salinity pressure. High heritability value held by age of harvest 0,52; number of tassel per plant 0,95; number of rice per plant 0,978; percentage of empty rice 0,96 and weight of 1000 grain seeds 0,81 characters. For plant height 0,31 and age of flowering 0,42 characters including to middle heritability. While for low heritability value there are weight of dry shoot -0,028;weight of dry root -0,082; relativity of shoot and root -0,25 and result of unhulled rice per plant 0,11 characters.
