Multienvironment testing is an important phase to study the interaction of G × E and to select stable hybrids for a broad environment or for a specific environment. To study the interaction of G × E and the stability of earliness and yield of Indonesian new sweet corn hybrids under different locations and seasons in West Java, Indonesia, eighteen hybrids were evaluated in six environments in West Java, Indonesia, and were analysed using parametric and nonparametric stability models, additive main effects and multiplicative interaction (AMMI), and GGE biplots. Results showed that the most promising sweet corn hybrids including hybrids G5 (SR 24 x SR 17) and G11 (SR 31 x SR 17) were identified. The parametric and nonparametric stability parameters and ASV were complement to the AMMI and GGE biplots in selecting stable and adaptable hybrids in terms of earliness and yield. G5 was selected as a high-response hybrid for grain yield to Jatinangor (E1, E2), Lembang (E3, E4), and Wanayasa (E5, E6), as well as earliness to Jatinangor (E2), Lembang (E3, E4), and Wanayasa (E5, E6). G5 sweet corn hybrid, therefore, is suggested to be extensively evaluated on farm and produced for smallholder farmers in West Java, Indonesia.

Respon pertumbuhan dan hasil cabai keriting (Capsicum annuum L.) Ck5 akibat perlakuan pupuk NPK dan pupuk hayatiResponse of growth and yield of curly red pepper (Capsicum annuum L.) Ck5 due to NPK fertilizer and biofertilizer Abstract. This study aims to find out response of growth and yield of curly red chili plant cv. CK5 as a result of NPK and organic fertilizer . The experiment was conducted in Sindanglaya Village, District Sukamantri, Ciamis Regency West Java Province, from August 2017 until January 2018. The experiment design used was Split Plot Design with 4 replications. The main plot was the dosage of NPK fertilizer consisting of two levels : 50% and 100% NPK, and the sub plot was concentration organic fertilizer consisting of three levels : 0%; 0.5%; and 1%. The results showed that : the effect of NPK dosage interaction with concentration of biological fertilizer occurs only at plant height of 28 day after planting, the best treatment was 100% NPK dosage with 0.5% biofertilizer concentration. NPK fertilizer and concentration of biological fertilizers independently affected the amount and weight of fruit. The best dosage of NPK in producing the amount and weight of fruit was 100% NPK, and the best concentration of biofertilizer was 0,5%.

Pengujian efektivitas berbagai jenis dan konsentrasi sitokinin terhadap multiplikasi tunas mikro pisang (Musa paradisiaca L.) secara in vitroThe experiment of effectiveness with concentration of cytokinin on micro shoot multiplication banana (Musa paradisiaca L.) on in vitro culture Diterima : 15 Juli Abstract The use of banana sucker continuously as a material of conventional propagation technic reduces quality and it takes a long time due to the increasing of disease accumulation. Therefore, the fast propagation by in vitro culture is needed. The aim of this experiment was to find out the best type and concentration of cytokinins for growth and development banana 'Kepok Kuning' in vitro. The experiment was carried out from October to December 2015 at Seed Technology Tissue Culture Laboratory of Agriculture Faculty, Universitas Padjadjaran. Completely Randomized Design (CRD) with eight treatments are the types and concentration of cytokinine was used in this experiment (2 mg L -1 BAP, 4 mg L -1 BAP, 2 mg L -1 2-iP, 4 mg L -1 2-iP, 0,08 mg L -1 TDZ, 0,2 mg L -1 TDZ, 2 mg L -1 Kn, 4 mg L -1 Kn). The results showed that 2 mg L -1 BAP was effective in increasing the explant shoot percentage (%) and length of shoot (cm).
