The quality component measurement of horticultural products becomes more important to achieve better quality products also to obtain uniform product. Recently, measurement by non-destructive methods turns out to be more needed, because consumers become more selective and demand producers to develop a quick, effective and accurate quality assessment system. Near Infrared Spectroscopy (NIRS) can measure plant contents quickly, relatively economical in a bigger scale, and importantly non-destructive. The measurement of quality components of green bitter gourd, such as firmness, water content, total soluble solid, and color, are important but have not been widely conducted.

Balanced organic and inorganic fertilization is expected to improve low nutrient on Inceptisols to increased snap bean production. The effect of the combination of N, P, K, and granule organic fertilizer on bean harvests was the purpose of this study. The parameters were leaf area index (LDA), shoot-root ratio, the weight of pods, pod length, pod diameter, percentage of the number of pods, marketable and unmarketable,and percentage of pods by quality class. The experiment was conducted in February to April 2016 at Ciparanje Experimental Farm, Faculty of Agriculture, Padjadjaran Univeristy, Jatinangor. The study was conducted using a randomized block design (RBD) with 10 treatments and 3 replications. The experimental results showed that N, P, K fertilizer and granule organic fertilizer (GOF) in the order of Inceptisols significantly affected the weight of pods. Application 50% of the dosage N, P, K fertilizer combined with 50% dosage of granule organic fertilizer resulted in a higher pod weight per plot, which reached 2 439.84 g. Keywords: an organic fertilizer, granule organic fertilizer, leaf area index, quality grade, shoot-root ratio,

Abstract. Kusumiyati, Kurniasari I, Oktavia AR. 2017. The color detection of two cucumber cultivars by NIR Spectroscopy. Asian J Agric 1: 59-65. The color of cucumber fruit can be estimated as fruit quality trait. Genotypes and cultivars affect the color of cucumber fruit. The estimation can be done quickly and without tissue damage by NIR Spectroscopy. The purpose of this study was to determine the accuracy of color quality values with NIR and conventional methods. The experiment was conducted at Horticulture Laboratory, Faculty of Agriculture, Padjadjaran University in 2013. The color components observed were L, a, b, hue and chroma. The results indicated that the predicted component of cucumber color approximates values obtained from conventional methods. Based on the data obtained, the correlation coefficient (r) of color component approaches 1.00 and the standard calibration error (SEC) is low or close to 0.00.
