Abstract

The current season shift caused the rice planting period in MT II to retreat around May-June this resulted in crop failure due to limited irrigation water only relying on rain. The cropping pattern which was originally rice bero, in several locations in Sumilir Village the planting pattern was only rice in MT 1, while entering MT II who planted rice experienced drought resulting in puso. In an effort to increase cropping in paddy fields after rice, it can be done for the cultivation of green bean palawija plants. Problems that arise include: a. cropping patterns in paddy fields in Sumilir Village are paddy-paddy and paddy-paddy so that paddy fields are still not widely used economically, b. planting green beans on land has never been done in the village of Sumilir, Kec. Kemangkon, c. the unavailability of superior varieties of green beans in the village of Sumilir, and d. Nutrition management of mung bean plants in the former paddy fields has not been mastered. To overcome the problems of partners, several technology solutions offered are technology transfer through mentoring, training and demonstration plots. Evaluation of activities is carried out in the form of monitoring which is carried out after the training, counseling, guiding and demonstration plots are completed. The results of the activity showed that farmers were able to absorb knowledge about the cultivation of green beans in paddy fields properly. The demonstration plot was carried out in the area of paddy fields in Sumilir Village with an area of 1.4 ha. The initial growth of plants showed that plants that were able to grow reached 80 percent. Low yield caused by drought stress since early vegetative phase.

Abstract

The aim of this research was to determine the effect of inorganic fertilizer proportion and organic fertilizer as well as its interaction to N uptake, N uptake efficiency, and physiological characters of rice plant. This research was conducted in the Experimental Farm of Agriculture Faculty of Jenderal Soedirman University Purwokerto, with soil type used was Inceptisol and located 110 m above sea level. This research was arranged using split plot design with four replicates. The main plots were the type of organic fertilizers i.e cow manure 5 t/ha, and straw compost 5 t/ha. The subplots were the proportion of inorganic fertilizers i.e P1: general dose recommendation (250 kg Urea, 150 kg SP-36 and 150 kg KCL), P2: 75% of general dose recommendation (187.5 kg Urea, 112.5 kg SP-36 and 112.5 kg KCL), P3: 50% of general dose recommendation (125 kg Urea, 75 kg SP-36 and 75 kg KCL), P4: P and K according to soil nutrient status + N according to Leaf Color Chart scale (LCC), P5: 150 kg SP-36, 150 kg KCl, and N according to LCC scale, and control (without fertilizer). The observed variables were leaf area index, leaf greenness, leaf chlorophyll content, N uptake, and N uptake efficiency. Data was analyzed using F test and if the differences were significant, the analysis was proceed with DMRT test at 5% error levels and orthogonal contrast test. The results showed that the dose of inorganic fertilizer increased the leaf area index, chlorophyll content, N uptake and N uptake efficiency. The reduction of inorganic fertilizer dose up to 50% of general dose increased the content of chlorophyll a. N uptake efficiency was higher in the N fertilizer added based on LCC and P and K based on soil nutrient status treatment than the recommendation dose when straw compost was applied.
