“…The use of sprinkler irrigation for fertigation allows for a decrease of production cost and leads to a better productivity of corn yield. Similar results regarding the effect of the fertigation rate on corn yield were obtained in several case studies [6,8,25]. The results of three nitrogen levels (120, 180 and 240 kg/ha) indicated that the interaction of nitrogen and irrigation has no significant effects on maize height.…”

A high efficiency of fertigation was established after three years of research at an ordinary chernozem on the production of corn hybrid DКС 4351 instead of traditional mineral fertilizing methods. Nitrates are washed out of the root layer after spreading urea on the soil surface before the cultivation in the spring. The nitrate content in the soil in the last two phases was 16-26% higher than in the 5-6 leaf phase after applying the KAC -32 solution with a sprayer on the soil surface.The mass of 1000 grains was the highest after several times urea application in dose N200 depending on irrigation rate. The maximum yield of corn grain was obtained by applying urea with rate N200 and КАС -32 with irrigation water during corn vegetation period. There is a tendency to increase the protein in corn grain during fertigation with urea and КАС -32. The data obtained show that the combination of irrigation with mineral fertilizer application is an effective way to save energy and material resources, increase the yield and grain quality.

Agricultural intensification has led to an elevated use of pesticides and fertilizers such as urea, without considering the negative effects these products can cause, such as acidification of the soil and the entry of lead (Pb) into the trophic chain. The objective of this research was to determine the effect of urea on the absorption of lead (Pb) in the leaf structure of corn (Zea mays L.), spinach (Spinacia oleracea L.), and cabbage (Brassica oleracea L.). These three plant species were exposed to five different concentrations of urea and a constant concentration of Pb in the form of Pb acetate for 93 days. The effect of urea and Pb was determined through analysis of the leaf structure. The results showed an increase in the dry weight of corn, whereas in spinach (T4) (1.5 g urea kg-1 of soil plus 0.5 g Pb kg-1 of soil) dry weight decreased as well as the fresh weight and foliar area. An increase in the chlorophyll index in corn, spinach, and cabbage was observed in the treatments with urea, and there was an influence on soil acidification. We also observed that spinach concentrated more Pb (T4) in its foliage at higher rates of N application. The idiosyncratic nature of the crop combined effects of Pb and N highlights the need for more research on this subject.

“…Kata kunci: irigasi mikro, nitrogen, mulsa plastik, pemupukan of the precision technologies that have been developed for vegetable crops is fertigation through drip irrigation. Fertigation is the application of fertilization together with water irrigation (Chauhdary et al, 2018). Through fertigation technology, the composition and rate of nutrients can be adjusted according to the physiological development of the plant, so that in addition to more efficient use of nutrients, it also affects plant growth and yield.…”

Chili (Capsicum frutescens L.) has an important role in Indonesian cuisine. Conventional crop management with less-efficient fertilizer application was still commonly implemented by farmers; on the other hand, fertilizer application through fertilizer will increase yield and reduce production costs. Research objectives were to find out the best fertilizer application methods through drip irrigation and obtain a nitrogen fertilizer source that can increase polyethylene mulched chili yield. This research was conducted in Inceptisol (Dytropept Fluventik, Isohiperthermik) soil type. The experiment was conducted at Bogor Agricultural University Research Station, Cikarawang, from June to December 2016. The first experiment was arranged in a randomized complete block design (RCBD) with three methods of fertilizer applications: split, drip, and conventional (no fertigation). The second experiment, from March to October 2017, was arranged in RCBD, with three N sources (Urea (46% N), ZA (21% N), and NPK (16-16-16)% N-P2O5,-K2O), with four replications. Results showed that split and drip fertigations had no different effect on total and marketable yield; however, the yields of both treatments were higher than that of conventional applications. The second experiment results showed that all N sources did not affect the growth and yield of chili.Keywords: fertilization, nitrogen, micro-irrigation, polyethylene mulch
