“…Nitrogen (N) in plants functions as a synthetic material for chlorophyll, protein, and amino acids [15]. Nitrogen is absorbed by plants during the growth period until seed ripening, so plants require continuous N availability at all growth stages until seed formation [16,17]. N deficiency affects productivity and yield quality; while excess N causes plants to fall over easily, besides being inefficient and having a negative impact on the environment [16,10,11,18,19].…”

In long dry season (El Nino), thousand hectares of agricultural land in Indonesia to experience drought, and sometimes wildfires occur naturally. Land management without burning and environmentally friendly agricultural cultivation needs to be done in the long dry season. It is not recommended to use crop residue that is burned on the land, since the residue can be composted into organic matter which later is returned to the agricultural land as organic fertilizer. Currently, about 40% farmers use local corn varieties. Corn farming lands in Indonesia are generally deficient in nitrogen. Consequently, drought tolerant new superior corn varieties complemented with right dose fertilizer based on plant needs, especially N fertilizer, are needed to increase corn productivity in the dry season. This research aimed to ascertain adaptive hybrid corn varieties and right N fertilizer rate on the growth and productivity of corn planted on the land without burning. The experimental design was Randomized Complete Block Design consisting of 2 factors. The first factor was corn varieties, namely Bima 19, Nasa 29, and JH 21; whereas, the second factor was N fertilizer rate, namely 64, 86.5, 109, and 131.5 kg ha-1. The combination of the two factors consisted of 12 treatments, which were repeated 3 times. The results showed that there was an interaction between the new high yielding varieties and the N fertilizer rate on corn productivity. Greater yields were performed in Bima 19 with N rate of 109 and 131.5 kg ha-1 and Nasa 29 with N rate of 131.5 kg ha-1 i.e., 8.45, 7.94, and 8.04 t ha-1, respectively. Bima 19 and Nasa 29 are drought tolerant high yielding corn varieties.

Alfisols have low fertility, so fertilization is carried out to increase soil fertility and support the growth of maize plants. The continuous use of inorganic fertilizers in high quantities can cause land degradation, so it is necessary to reduce the amount by adding other fertilizers, such as organic fertilizers, as well as the relatively high price of inorganic fertilizers. This research was aimed to examine the potential of organic fertilizers in replacing inorganic fertilizers. The experimental design was a completely randomized block design with nine combination treatments of organic and inorganic fertilizers with three replications. The results showed fertilizer treatment ½ NPK + 1 PO affected and increased levels of organic C, CEC, base saturation, total N, and available P in Alfisols and maize yield. However, it did not significantly affect pH, base saturation and available S in Alfisols. The chemical properties of the soil had increased values of 48%, 9.01%, 61.3%, and 134.5%, respectively. The treatment of ½ NPK + 1 PO increased maize productivity by 47.76% compared to the control with the productivity of 12.7 t ha-1, which the results were not significantly different from standard NPK. Thus, the application of 10 t ha-1 of organic fertilizer has the potential to replace ½ doses of inorganic fertilizer.

“…The presence of macro and micro nutrients can possibly replace the difference in N, P and K. In relation to nutrient availability, the N element in fish waste LOF is thought to play a direct role in increasing stem diameter. According to Saragih et al (2013), the element N is a constituent of plant biomass, including the diameter of plant stems. The more N given, the higher the biomass produced so that the stem diameter also increases.…”

The productivity of purple eggplant has decreased and consumption continues to increase, it is necessary to increase the productivity of purple eggplant. Increasing productivity can be done by applying liquid organic fertilizer (LOF) derived from organic waste such as banana peels and fish waste. The purpose of this study was to determine the type and concentration of LOF that can help the growth and yield of purple eggplant. This research was conducted on the land of the Faculty of Agriculture, University of National Development (UPN) "Veteran" East Java in March to July 2022. The study used a factorial Randomized Block Design (RBD) consisting of 2 factors. The first factor was the LOF of banana peels and LOF of fish waste. The second factor is the LOF concentration level, namely 10%, 15%, 20%, 25% and 30%. The results showed that the treatment combination of fish waste LOF with a concentration of 30% gave plant with a biggest stem diameter of 1.01 cm. While the treatment combination of fish waste LOF with a concentration of 25% gave results with a total of 16.78 flowers and a total fruit weight of 1435.61 g/plant.
