Effectiveness of rice straw with biodecomposer and biofertilizer application in new land clearing in Merauke, Papua

Abstract

In order to fulfil rice production, there were new land clearing programs outside Java, including Merauke, Papua. There were several obstacles on rice cultivation in this area such as low soil fertility which has an effect on less optimal production. The objective of the research was to determine the effect of rice straw with biodecomposer and biofertilizer application for improving soil quality in new land clearing in Merauke, Papua. The research design was a split plot with the main factor was fertilizer (with and without rice straw with biodecomposer and biofertilizer application). The sub factor was three kinds rice varieties. The data were collected consist of soil chemical and biological properties, the rice growth and yield components. The results showed the addition of fertilizer did not significantly improved soil quality in new land clearing in Merauke, Papua. On the contrary, biofertilizer affect to seed vigor and viability in the nursery. The fertilizer addition significantly effected on rice growth and yield components, it was suspected by rice varieties having different resistance to pests and diseases and straw as compost will suppress the blast growth through temperature factor during decomposition. The highest yield was reached by Inpari 33 of 8.20 Mg ha−1.

Sustainable cultivation of red chili plants (Capsicum annuum L.) through a composition of NPK and biological organics fertilizers

“…This indicates that the application of sludge compost followed by biofertilizer will have a positive impact on the soil so that it can improve the level of fertility and nutrient availability which will affect plant growth and development. According to [17], the use of organic matter and biofertilizer is a solution in overcoming the low level of soil fertility and the ability of microorganisms contained in compost to spur plant growth, fix nitrogen and dissolve phosphate. The number of fruits is the total number of fruits formed in each sample plant in each plot.…”

Pengembangan VUB Inpari IR Nutri Zinc dan Inpari 43 Agritan GSR pada Lahan Sub Optimal di Papua

“…Jauh sebelumnya, VUB khusus untuk lahan rawa yang dihasilkan Kementerian Pertanian dikembangkan pada lahan rawa pasang surut di Merauke menghasilkan produktivitas 5.10 t/ha dan 4.20 t/ha untuk Inpara 2 dan Inpara 4 (Handayani et al, 2016). Dengan bantuan pemberian jerami terdekomposisi dan pupuk hayati, produktivitas Inpari 33 di Merauke mencapai 8.2 t/ha (Wulanningtyas et al, 2021). Nilai di atas lebih tinggi daripada rata-rata produktivitas padi di Papua yaitu 3.9 t/ha (BPS, 2021).…”

Utilization of solid organic waste as a biofertilizer formulation for upland rice plants supports sustainable rice farming

“…This study used a consortium of bacteria derived from two rice straw bacteria (Bacillus cereus JP6 and Bacillus cereus JP7), two acacia litter bacteria (Providencia vermicola SA1 and Bacillus cereus SA6), and two oil palm empty fruit bunches (Proteus mirabilis TKKS3 and Proteus mirabilis TKKS7) [6].
