Caisim (Brassica juncea L.) is one of vegetable commodities that has a high commercial value. Many people like it because it has a good taste and it contains several kinds of vitamin and mineral that good for health. This research aims to know the influence of liquid bio organic fertilizer and inorganic fertilizer addition to post harvest product caisim leaf and know the best combination of fertilizer for post harvest product caisim leafquality. Data analysis used is Analysis of Variance (ANOVA) and then continued by test significant different used Duncan Multiple Range Test (DMRT) 95%. The caisim plant that have been harvested then being observed on its fiber content, water content, and physical appearance. The result showed thatthe addition of liquid bio organic fertilizer and inorganic fertilizer has not influence for water content and physical appearance of caisim leaf, but it has an influence on fiber content. Treatment with basic media with the addition of 1 mL + 2,17 g NPK is the best treatment to increase fiber content of caisim leaf Tosakan variety.   Keywords: liquid bio organic fertilizer, caisim, quality of post harvest product

The experiment was laid out in randomised block design (RBD)during the crop season of 2004 -05 and 2005-06 at the research farm of J.V.P.G. College, Baraut, Baghpat (U.P.) comprising 10 treatments with 3 replications. DEBPCFYM, combinations of DEBPC+FYM and inorganic fertilizer significantly increased seed yield. Biological yield and quality content of Indian mustard. Among the various treatments, application of FYM 5t/ha + DEBPC 3t/ ha recorded highest seed yield, biological yield and all the quality contents in both the years.

This paper summarizes a series of field experiments that investigated the effects of organic and inorganic nutrients on sweet potato tuber yield in the humid lowlands of Papua New Guinea. In the first experiment, plots were planted with Piper aduncum, Gliricidia sepium and Imperata cylindrica, which were slashed after one year, whereafter sweet potato was planted. Sweet potato yield was lowest after Gliricidia fallow, but no yield differences were found after piper and imperata fallow. In the second season, there was no significant difference in sweet potato yields. The second experiment consisted of a factorial fertilizer trial with four levels of N (0, 50, 100, 150 kg ha–1) and two levels of K (0, 50 kg ha–1). Nitrogen fertilizers increased yield in the first season, but depressed tuber yields in the second and third seasons. Potassium fertilizer had no effect on marketable tuber yield. The third experiment consisted of a comparison between N from inorganic fertilizer and poultry litter at four rates (0, 50, 100, 150 kg ha–1). No difference was found between the inorganic fertilizer and poultry litter, and the highest yields were found at 100 kg N ha–1. In the second season no significant response was observed. Although yield variation was considerable, this series of experiments has shown that sweet potato yield can be significantly increased by inorganic or organic N applications. Sweet potato yields after fallows were less variable than after inorganic nutrient inputs. Inputs of inorganic fertilizer or poultry litter may strongly increase or decrease tuber yields.

The maximization of organic substrates production for land sustainable management is a major challenge for agricultural production in countries like Burkina Faso. The objective of this study was to assess the quantity and the quality of organic substrates produced by poultry activity on station. Therefore, 54 local chickens at eighteen months old were allocated to 3 batches (boxes), with 18 chickens per batch. Rice husk was spread on the floor of the 3 boxes as litter for the chickens. The chickens were reared on the litter for 6 months in semi-confinement. Then, the poultry litter (PL) was used as substrate for maggots’ production. The quantities and the chemical characteristics of the raw PL as well as the residues of the litter after maggots’ production (RMP) were determined, and, simulations were done to estimate the quantities of organic substrates and the chemical nutrients that poultry farms can produce. The results show a production of 226.06 kg DM of PL after 6 months of semi- confinement, with a decrease of 30.33% when the PL was used to produce maggots. Carbon and nitrogen contents also registered a decreased of 8.83 and 8.39% respectively when PL was used to produce maggots. However, with phosphorus and potassium contents, an increase of 49.12 and 34.21% were noted, respectively. It was concluded that small poultry farmers with 30 to 100 adult chickens, could produce the equivalence of 100 to 300 kg of fertilizer (NPK (15-15-15)) in semi-confinement condition.Keywords: local poultry, litter, organics substrates, maggot production, fertilizer, small farm.
