THE EFFECT OF POROSITY LEVEL ON THE NUMBER OF MYCORRHZA SPORES AND THE LENGTH OF CATTLE CHILI ROOTS
No full textPorosity is the proportion of total pore space or empty space in a unit volume of soil that can be occupied by water and air (Hanafiah, 2015). Solid soil will interfere with plant root penetration so that plant growth (Haridjaja et al., 2010). Appropriate soil porosity can optimize the increase of mycorrhizal spores. High oxygen content can increase the spores. Flooded soil has little pore space so the oxygen content is low which causes the development of mycorrhizal spores to be low (Gustian et al., 2015). Research needs to be carried out to determine the best soil porosity for increasing of mycorrhizal spores and cayenne pepper root growth. The research hypothesis is that different levels of porosity influence the mycorrhizal spores and the root length of cayenne pepper plants. Research was the Satu Nusa Lampung University Greenhouse and the Soil Science Laboratory, Lampung State Polytechnic. The research was conducted from July to October 2024. The research used RAL repeated 5 times to obtain 25 total treatments. Each treatment consisted of 4 plants so there were 100 plants. Very poor porosity (P1), poor porosity (P2), poor porosity (P3), good porosity (P4) and porous porosity (P5). The results of the research show that different levels of porosity have a significant effect on the mycorrhizal spores and the root length of cayenne pepper plants. The best level of porosity was porous porosity with a number of spores of 25.70 g and cayenne pepper plant root length of 32.90 cm.

EFFECT OF FERTILIZER TYPE ON THE PRODUCTIVITY OF ELEPHANT GRASS (PENNISETUM PURPUREUM): A COMPARATIVE STUDY OF GOAT MANURE COMPOST, UREA, AND NPK ON INCEPTISOL SOIL
No full textForage productivity strongly depends on appropriate fertilization strategies, particularly in the cultivation of Pennisetum purpureum (elephant grass), a key tropical livestock feed. This study aimed to compare the effects of three fertilizer types—goat manure compost, urea, and NPK—on the productivity of elephant grass grown on inceptisol soil. A Completely Randomized Design (CRD) was employed with four treatments (no fertilizer, 2 tons/ha compost, 150 kg/ha urea, and 422 kg/ha NPK) and three replications. Observed parameters included fresh biomass yield, dry matter yield, and organic matter yield. The results indicated that NPK treatment significantly outperformed others in all parameters: fresh biomass (35.27 tons/ha), dry matter (5.88 tons/ha), and organic matter (5.35 tons/ha). Urea provided moderate results, while compost did not significantly differ from the control. These findings suggest that NPK delivers readily available macronutrients, which greatly enhance vegetative growth. Nevertheless, goat manure compost holds long-term potential to improve soil structure and fertility. The study recommends integrating organic and inorganic fertilization as a sustainable approach in tropical forage production systems.
