Effects of Methods of Seedbed Preparation and Organic Amendments on Soil Properties, Growth and Yield of Sunflower (Helianthus annuus L.) in a Humid Zone of Nigeria

An abandoned land after tin-mining activities are degraded lands with undulating and destructed land scape and low soil fertility status. The objective of this study was to determine the effects of organic amendments on the soil properties, growth, and grain yield of corn (Zea mays L.) on abandoned tin-mining areas in Bangka Island, Bangka Belitung Archipelago. The field experiment was conducted at the abandoned tin-mining areas in Cambai Village, Bangka Belitung Archipelago. Five treatments of organic amendments were applied and replicated three times and laid out in a Randomized Completely Block Design. All treatments were applied with the recommended rate fertilizer of 135 kg N ha-1, 72 kg P2O5 ha-1, and 120 kg K2O ha-1. The treatments were T1= 20 Mg chicken manure ha-1;T2= 20 Mg cattle manure ha-1; T3= 20 Mg rice straw compost ha-1; T4 : 10 Mg of chicken manure ha-1 + 10 Mg rice straw compost ha-1; and T5= 10 Mg cattlemanure ha-1 + 10 Mg rice straw compost ha-1. Application of organic amendments (chicken manure, cattle manure, and rice straw compost) on abandoned tin-mining land improved soil fertility due to the increasing of soil pH and nutrient availability, especially available-P and -K, and exchangeable bases. Application of chicken manure and cattle manure were significantly better than rice straw compost to improving soil fertility, nutrient uptake, growth and yield of maize. Application of cattle manure gave the highest yield of maize, namely 6.24 Mg ha-1.

Four Levels

A factorial experiment was applied according to Randomized Complete Block Design (R.C.B.D) with three replications, during the spring season 2017 in Diyala / Baquba / Buhriz city, using silt loam soil to study the effect of four levels of foliar fertilization with humic acid 0, 2, 4, 6 ml.L-1 in the growth and yield of sunflower, Helianthus annuus L. (LuLeo). The results showed significant differences for level of humic acid 6 ml.L-1 in plant height which gave an average 213.73 cm, leaf area of the plant 5597.32 cm2, chlorophyll index 48.64 SPAD, dry weight of the plant 215.0 g, number of seeds in the flowery disc 1494 seed.disc-1, 1000 seeds weight 88.3 g, plant yield 127.91 g.plant-1, total yield 6.81 ton.h-1 and oil percentage in the seeds 43.184%, while the level 4 ml.L-1 humic acid gave the highest average for the protein percentage in the seeds 18.34%.
