Effect of Slurry Composting and Bio-filtration (SCB) by Fertigation on Soil Chemical Properties and Growth of Red Pepper (Capsicum annuum L.)

Physio-chemical properties of hybrid chilies (Capsicum annuum L.), parental lines and commercial varieties were evaluated in three experiments and showed significant differences among them. Heterosis, and heterobeltiosis were studied in hybrids while, combining abilities were investigated in maintainers and restorers. Positive statistical differences in the general combining ability of the maintainer lines for vitamin C, capsaicin and Hue were observed and general combining ability indicated that, CA1286 and CA1303, were good maintainers for the improvement of capsaicin and vitamin C. The other maintainers;-, CA1441 and CA1442, are good for the improvement of L* and Chroma. The maintainer, CA1441, was better than CA1442 for capsaicin content,- while the maintainer, CA1442, was better than CA1441 for vitamin C. Positivity and statistically significant differences among the restorers were observed for vitamin C, capsaicin, Hue and Chroma and the lines;-, CA 1447, CA 1448, CA 1449, CA 1450 and CA 1451, were useful for the improvement of these physio-chemical properties of chilies.

Postharvest Ripening

The influence of post-harvest ripening conditions of pepper Aleva NK picked in red maturity stage on the composition of volatiles in spice paprika was investigated by GCMS. The post-harvest ripening in the dark and under daylight was conducted under semicontrolled conditions for two weeks. The obtained chromatograms indicated that the aroma of investigated spice paprika consisted of a large number of volatile compounds regardless of the application and conditions of the post-harvest ripening. The main volatiles of the analyzed paprika samples were fatty acids and their esters, terpenes and terpenoides and aldehydes and ketones. The share of fatty acids and their esters decreased during the post-harvest ripening, and the ripening in the dark favored the decrease. The share of terpenes and terpenoides and the share of aldehydes and ketones in the total volatiles increased during the post-harvest ripening. The post-harvest ripening in the dark favored the increase of the share of terpenes and terpenoides, while the ripening under daylight favored the increase of the share of aldehydes and ketones.

ABSTRACTApplication of liquid organic fertilizer formula plus on degraded soil to improve the productivity of the land and chili (Capsicum annuum L.) productionSoil exploitation in large numbers occurred in the District Wanaraja of Garut Regency. Excavation of soil more than 2 meters from the top layer for the manufacture of red bricks has exceeded the ability of the soil to re-establish its structure. So that the soils, which were agricultural lands, can be classified as degraded soils with less fertility and chemical properties. Lans reuse for agriculture requires adequate recovery and fertilizer input. This study aimed to determine the formula of LOF (liquid organic fertilizer) plus used with NPK compound fertilizer on degraded soil to improve the soil productivity. The design used was a Simple Randomized Block Design (RBD) by 10 combinations of LOF plus treatment with NPK compound fertilizer as follows: A = Control (degraded soil, no fertilizer), B = 0% LOF + 1 NPK, C = 0.25% LOF + 1 NPK, D = 0.50% LOF + 1 NPK, E = 0.75% LOF + 1 NPK, F = 1.00 % LOF + 1 NPK, G = 0.5% LOF + 3/4 NPK, H = 0.5% LOF + 1/2 NPK, I = 0.5% LOF + 1/4 NPK, J = 0.5 LOF + 0 NPK, and K = 1 NPK of normal soil that all replicated three times. The results showed that the degraded soil of red bricks required concentration of LOF above 0.5% to 1% when applied with 1 dose of standard NPK. It is able to balance the uptake of nutrients P, Ca, and B and percentage of fruitset in chili commodities equivalent to normal soil.Keywords: Chilli, Liquid Organic Faertilizer (LOF), NPK, Soil degrededABSTRAKEksploitasi tanah dalam jumlah yang besar terjadi di Kecamatan Wanaraja, Kabupaten Garut. Terjadinya penggalian tanah lebih dari 2 meter dari lapisan atas untuk pembuatan batu bata merah melampaui kemampuan tanah untuk membentuk struktur tanah kembali, sehingga tanah-tanah yang sebelumnya merupakan tanah pertanian ini dapat digolongkan menjadi tanah terdegradasi dengan sifat kimia kurang subur dan pemanfaatan kembali untuk pertanian memerlukan pemulihan dan input pupuk yang cukup. Penelitian ini bertujuan untuk mengetahui formula pupuk cair organik (PCO) plus yang digunakan bersama NPK pada tanah terdegradasi guna meningkatkan kembali produktvitas tanahnya. Rancangan yang digunakan adalah RAK sederhana dengan 10 kombinasi perlakuan PCO plus bersama NPK yaitu A = Kontrol (tanah terdegradasi, tanpa pupuk), B = 0% PCO + 1 NPK, C = 0,25% PCO + 1 NPK, D = 0,50% PCO + 1 NPK, E = 0,75% PCO + 1 NPK, F = 1,00% PCO + 1 NPK, G = 0,5% PCO + 3/4 NPK, H = 0,5% PCO + 1/2 NPK, I = 0,5% PCO + 1/4 NPK, J = 0,5 PCO + 0 NPK, dan K = 1 NPK tanah normal. Semua perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa tanah terdegradasi bekas tambang batu bata merah memerlukan konsentrasi PCO di atas 0,5% sampai dengan 1% apabila diaplikasikan bersama 1 dosis NPKstandar. Hal ini mempu mengimbangi serapan hara P, Ca, dan B serta persen fruitset pada komoditas cabai setara dengan tanah normal.Kata Kunci: Cabai, NPK, Pupuk Cair Organik (PCO), Tanah terdegradasi
