Dryland has low soil fertility. Efforts that can be made to improve soil fertility are fertilizer technologies such as green manure compost. The aim of this study was to determine the type and dose of green manure to increase the growth, production and nutrient uptake of maize in the dryland. The research was conducted in Sidera Village Sigi Biromaru District, Sigi Regency, Central Sulawesi from June to December 2018. The research used a factorial randomized block design. The first factor is the type of green manure consisting of three levels, namely mungbean green manure (K1), peanut green manure (K2) and Centrosema pubescens green manure (K3). The second factor is the dose of green manure which consists of three levels, namely 5 t. ha-1 (D1), 7.5 t. ha-1 (D2) and 10 t. ha-1 (D3). Thus, there are 9 treatment combinations, each treatment consisting of 3 replications so that there are 27 experimental units. Data were analyzed statistically using the F test and if significantly different it was followed by the least significant difference (LSD) Fisher’s test, P-value 0.05. These results showed that the types and dose of green manure increase the growth and yield of maize, namely leaf area, stem diameter, cob length, the weight of 100 dry shelled seeds, and production per hectare of the dry weight of corn shelled. The highest nutrient uptake and maize production were obtained in the application of C. pubescens green manure at a dose of 10 t. ha-1, namely nitrogen uptake of 7.68%, phosphorus of 0.39%, potassium of 0.09% and yield of 6.44 t. ha-1.

The objectives of this work were to evaluate the management of N and S (as ammonium sulphate) fertilization under no-tillage system on the components of maize productivity and on N and S accumulation in the crop, as well as to evaluate the minimum value of the Nitrogen Sufficiency Index (NSI 0.95) as an indicator for side dressing requirements. The experiment had a completely randomized block design with six treatments and four replications carried out in Red Latosol dystrophic soil (Hapludox), in Campo Mourão, Paraná State, where the following treatments in summer growth maize were applied: T1- 120 kg ha-1 N in seeding; T2- 120 kg ha-1 N in side dressing; T3- 40 kg ha-1 N in seeding and 80 kg ha-1 N in side dressing; T4- 30 kg ha-1 N in seeding and 90 kg ha-1 N in side dressing, monitored by a chlorophyll meter using the Nitrogen Sufficiency Index (NSI); T5- 120 kg ha-1 N anticipated in wheat seeding; T6- without nitrogen fertilization. NSI was determined by the relationship between the leaf chlorophyll index (ICF) average of T4 plants and that one in the plot fertilized with 120 kg ha-1 N at the maize seed sowing (T1). During two years, ammonium sulphate was applied to the maize crop after wheat under no tillage system. In the first year, with adequate rainfall, the maize yield was similar to the one in which the complete ammonium sulphate dose application was done in maize seeding and side dressing. The anticipated fertilization to wheat seed sowing resulted in maize yield without difference from the parceled form. In the second year, with irregular rainfall, all treatments with N were similar and they increased maize yield compared to that without N fertilization. NSI of 0.95 was not efficient to evaluate maize N requirements in side dressing, and resulted in lower maize yield. N was accumulated mainly in the grains unlike S that accumulated in the plant shoots; both were highly correlated to maize productivity.

The objective to evaluate the maize yield components as a function of the top-dressing nitrogen partitioning in maize plants with conventional and transgenic technology. The experiment was carried out in the agricultural crops of 2012/2013 and 2013/2014, in the municipality of Tenente Portela-RS, Brazil. The experiment was set up in a randomized block design in a factorial scheme with two genetic technologies x 11 nitrogen fertilization treatments, arranged in three replications. The treatments were composed of top-dressing applications in the phenological stages V2 - two fully expanded leaves, (V2), V4 - four fully expanded leaves, (V4), V6 - six fully expanded leaves (V6) and V8 - with eight fully expanded leaves (V8) and split applications in V2+V4; V2+V6; V2+V8; V4+V6; V4+V8; V6+V8; and V2+V4+V6+V8. There was interaction between genetic technologies and levels of nitrogen fertilization in the maize crop. The highest grain yield was obtained with conventional technology because it presented plants with greater prolificacy, ear diameter and number of grains per row. Grain yield was superior with nitrogen fertilization in V4 and in nitrogen splitting in the V4 + V6, V4 + V8 and V2 + V4 + V6 + V8 stages.

Abstract Successful cultivation of maize depends largely on efficient weed control, adequate supply of essential nutrients and sufficient soil moisture. Screenhouse and field trials were conducted at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta, Nigeria during the early and late cropping season of 2013 to evaluate effects of biochar integrated with manual weeding and pre-emergence herbicides on weed control efficiency and productivity of maize. The screenhouse trial was a 6 × 5 factorial experiment fitted into Completely Randomized Design in three replicates. The two factors were biochar: 0, 2, 4, 6, 8 and 10 t ha−1 and weed control methods: weedy check, hoe weeding at 6 Weeks After Sowing (WAS), hoe weeding at 3, 6, and 9 WAS, pre-emergence herbicide application (Codal Gold) at 1.0 and 2.0 kg a.i./ha−1. The field trial was laid out in split-plot arrangement fitted into Randomized Complete Block Design with three replicates. The three main treatments plots on the field consisted of the optimum rates of biochar obtained in the screenhouse (10 t ha−1) compared with 20 t ha−1 and 0 t ha−1 which served as the control. The sub-plots treatments consisted of weed control methods used in the screen house experiment. Data were collected on grain yield and weed dry matter. The result showed that biochar at 10 and 20 t ha−1 in the screenhouse and field trials, respectively, resulted in significantly (P < 0.05) higher grain yield compared with other rates tested. Highest grain yield was obtained in pots hoe weeded thrice at 3, 6 and 9 WAS. Whereas similar grain yield was recorded in plot weeded once at 6 WAS and that hoe weeded at 3, 6 and 9 WAS in the field experiment. Biochar application of 20 t ha−1 gave optimum maize yield. Among the weed control treatments manual weeding either at 6 WAS or at 3, 6 and 9 WAS recorded the highest grain yields. Therefore, incorporation of biochar with either preemergence herbicide or manual hoe weeding would enhance the growth and yield of maize.
