This article aims to study the effect of different time intervals for bed maturation in compost sheds for dairy cattle, such as organic manure in maize crop for silage. The experimental design was a randomized block in split-plot with five treatments, six collection times, and five replicates. The data were submitted to variance analysis and compared by Scott-Knott. Sigmoid functions of logistic growth were adjusted to the data. The treatments with addition of fresh and mature compost with nitrogen cover showed higher shoot dry matter production when compared to treatments without compost. For maize plant height, stalk diameter and number of leaves, it was observed that from 35 days after plant germination, these variables were considered superior for the treatments that received bedding. The sigmoid function was proper to represent the plant growth to the silage point. It is concluded that the use of bedding from compost sheds as an organic manure is recommended as a sustainable alternative in the reuse of waste from milk production.

This study presents the results of a four-year field experiment assessing the effectiveness of phosphorus application in maize cultivation according to the depth of two-component fertilizer (NP) placement in the soil layer, type of nitrogen fertilizer and date of application. Nitrogen utilization from mineral fertilizer was low—on average, 37.1% during the four years of research. The nitrogen metabolism index, measuring the agricultural and physiological efficiency of nitrogen use, confirmed the significant impact of NP fertilizer placement at 10 and 5 cm as optimal in maize fertilization. The use of nitrogen in maize cultivation before sowing, compared to the application of this component at the phase of 5-6 leaves BBCH 15/16 stage (stage of leaf development with five–six leaves unfolded), significantly increased the agricultural and physiological effectiveness of nitrogen applied in mineral fertilizer. Ammonium nitrate application before sowing the maize, compared to top dressing at the BBCH 15/16 stage, significantly increased nitrogen uptake and utilization from mineral fertilizer. Date of urea fertilizer application to the soil did not have a significant impact on these indicators in maize cultivation.

Maize (Zea mays. L) is a source of carbohydrates as food, feed ingredients for livestock and industrial raw materials and bioethanol raw materials. To optimize the productivity of local maize, fertilization can be done. The use of organic fertilizers is very good for maintaining soil health, one of them is vermicompost. The application of vermicompost fertilizer is the right solution in this problem because composting of organic waste with the help of earthworms (Lumbricus sp.) contains high nutrients. The needs of adequate nutrient and growing environment will maximize the genetic potential of a variety. This research was conducted with the aim to determine the effect of vermicompost fertilizer on growth and yield of several maize varieties (Zea mays L). This study used a grooved plot design (Strip Plot) with 3 replications. The vertical path consists of 4 doses of fertilizer, namely P0 = 0 ton /ha, P1 = 4.5 tons/ha, P2 = 9 tons/ha, and P3 = 13.5 ton/ha. Horizontal path consists of 4 varieties, namely V1 = Dampit local variety, V2 = Arjuno superior variety, V3 = Karangploso local variety and V4 = Madura local variety (V4). Results of this study shows that fertilizer dose is 13.5 tons/ha (P3) and themaizeDampit localvariety (V1) showed good results on the growth and yield of maize crops. The results of P3V1 in maize plants were 2.66 kg of maize per bed and 1.15 kg of maize per bed. Keywords: Maize, Varieties, Vermicompost.

The response of crops to the application of biofertilizers in the soil is not yet well established. Therefore, we carried out this study with the objective of evaluating the productive potential of maize fertilized with doses of sewage sludge, comparing with the use of mineral fertilizer over four agricultural seasons. The experiment was conducted in a Red Dystroferric Nitosol (Ultisol) in a randomized block design and repeated measures in time. The treatments consisted of five doses of sewage sludge and one treatment using nitrogen, phosphorus and potassium in formulation. All fertilizations were carried out at maize sowing at four planting times (summer and 2nd crop of 1st agricultural year and, summer and 2nd crop of 2nd agricultural year) and replicates. The results showed a cumulative increase in the P, Ca, Mg and Zn leaf concentrations over the four seasons crops, when the sewage sludge was used in the 30 and 40 Mg ha-1 doses. However, reductions in plant height, weight and maize cob diameter, mass and grain yield were observed at the end of the last harvest. The treated sewage sludge is a viable alternative for maize fertilization in the first harvest, provides increases in grain yield in the order of 1.35 Mg ha-1 and can be recommended instead of NPK mineral fertilizers in built-up fertility soils.

In a long-term field experiment set up at the Látókép experimental station of the Center of Agricultural Sciences of Debrecen University, the data of the last five years (1995-1999) were analyzed to determine the crop production factors with the greatest influence on maize production and the relationship and interactions between irrigation and fertilization.In the extremely dry year of 1995, fertilization was found to cause substantial yield depression in the absence of irrigation. According to results of analysis of variance, fertilization significantly reduced the maize yield by 40-90% compared to control plots. Under irrigated conditions, there was a considerable increase in the maize yield, the yield surplus being 4.4-9.4 t ha-1, depending on the nutrient supply level.During the period from 1996-1999, when rainfall conditions were favorable for maize, fertilization significantly increased the maize yield even without irrigation over the average of the four years. The yield surplus due to fertilization was 3.9-4.6 t ha-1, depending on the fertilization rates. The maximum yield surplus was obtained on plots fertilized with 120 N kg ha-1, while at the rate of 240 N kg ha-1 the maize yield did not differ significantly from this value. During the period examined, corn yield was significantly higher at all three nutrient supply levels as the result of irrigation than in the non-irrigated treatment. As in the case of non-irrigated conditions, the highest fertilizer dose did not result in a substantial yield increase. An analysis of the interaction between fertilization and irrigation indicated that the yield-increasing effect of fertilization was not significantly different under irrigated and non-irrigated conditions. The significant year x irrigation interaction was confirmed by the fact that the yield surplus (1.3-2.3 t ha-1) differed greatly from the irrigation effect recorded in 1995.
