Abstract

The decline in crop productivity can be caused by environmental factors. Lack of water availability, nutrients, light gain and competition between plants at denser plant spacing and competition for plants with weeds can lead to a less optimal growth of crops, which results in less production. This study aims to determine the effect of mulch use with several different spacing on the growth and yield of mustard plants. The study was conducted using Factorial Complete Group Random Design (RCBD) which was repeated 4 (four) times. The first factor is the type of mulch consisting of three levels, namely M0: without mulch, M1: black silver plastic mulch, M2: straw mulch. The second factor is the spacing which consists of three levels, namely JT1: 20x25 cm, JT2: 30x25 cm, JT3: 40x25 cm. Observation parameters consisted of plant height, number of leaves, leaf area, root length, and plant fresh weight. Data analysis was performed using SAS software with variant analysis (Anova) at the level of 5%. If the results of variance analysis show a significant difference between treatments, the analysis is continued by Duncan's multiple distance test (DMRT). The results showed that the provision of straw mulch with the spacing of 30x25 cm between plants showed a better effect with a higher value, namely the number of leaves 13.50 strands, leaf area 63.13 cm2, root length 8.18 cm and fresh plant weights of 210.00 grams/plant compared to other treatment.

Abstract

Giving trichoderma and compost is one way to maximize the function of roots and nutrient availability to be absorbed by plants so that it affects plant growth and yield. This study aims to determine the effect of giving trichoderma and compost on the formation of root nodules and peanut crop yields. The study used a Randomized Block Design (RBD) method which consisted of 6 treatments that were repeated 4 times, so that there were 24 experimental units. The treatment consisted of P0: control (without trichoderma and compost); P1: trichoderma 40 grams + 1 kg of compost; P2: trichoderma 60 grams + 1 kg of compost; P3: 80 gram trichoderma + 1 kg of compost; P4: 100 gram trichoderma + 1 kg of compost; P5: 120 gram trichoderma + 1 kg of compost. The parameters observed were number of root nodules, number of active root nodules, number of inactive root nodules, number of pods per plant, pod weight per plant, number of empty pods, number of filled pods, and number of seeds per pod per plant. Observation data were analyzed using SAS software. Analysis using variance analysis (ANOVA) at 5% level. If the results of the analysis of variance showed that there were significant differences between treatments, the analysis was continued with Duncan's multiple range test (DMRT). The results showed that administration of trichoderma and compost with the highest dose (P5: trichoderma 120 gram+1 kg of compost) was among all the best treatments on the number of nodules. While the lowest dose of P1 (trichoderma 40 gram+1 kg of compost) gives the highest yield for the production component (number of pods per plant, pod weight per plant, number of filled pods, and number of seeds per pod per plant).
